FleXiseat floor seat

January 27, 2017 in Solution


This DIY product is designed for a three years old boy that was born with cerebral palsy. He has an inadequate trunk control so he can not sit independently, he would fall on his side.

At home he sits in a custom tailor made seatshell. But this is too big to take everywhere along. His parents like to go out by bike to friends or family, but there is always the problem that they can’t let hem sit on a normal chair to play with other children.

The question of the parents was to make a chair which is foldable, easy to carry, giving enough support so that the boy can sit straight and play with his friends, but still compact to put in the bicycle bag.

A shot movie, following on the intractable, will explain the advantages of the seat.

Step 1: Materials needed

Materials needed

Step 2: Saw the wooden pieces

Saw the wooden pieces

Buy two different pieces of wood, a 3mm multiplex and a 15mm multiplex. Than saw two 395x300x4mm pieces and two 330x400x15mm pieces.
Drill holes in the 15 mm pieces; drill in a line 35mm of the border. The distance between two holes is 3 mm.Buy two different pieces of wood, a 3mm multiplex and a 15mm multiplex. Than saw two 395x300x4mm pieces and two 330x400x15mm pieces.

Drill holes in the 15 mm pieces; drill in a line 35mm of the border. The distance between two holes is 3 mm.

There have to be cut out rectangulars as well, this can also be done with a drill, by drilling holes close to each other.

Step 3: Attach a lath

Attach a lath

First there has to be sawed a lath 330x20X15, we attached this to one of the wooden pieces of 15 thickness, with an air staple gun but this can also be done manually.

Step 4: Connecting the wooden pieces

Connecting the wooden pieces

Weave the rope between the thickest wooden pieces by using the saddle stitch. This technique will ensure the proper firmness.

Step 5: Attach Foam

Attach Foam

Attach the foam using an air staple gun or an manual stapler.

Step 6: Skai


Attach the leather, by using an air staple gun or manually with a stapler.

Step 7: Handles


Stich handles and attach them onto the back of the wooden pieces.

Step 8: The back

The back

Attach the thinner wooden pieces with some nails onto the backs of the seat, to hide the ugly staples.

Step 9: Add the straps

Add the straps

First make a finishing stitch around the openings for the buckles.

We used a support pants, because the child can not sit straight by himself. That little pants ensures support around the waist and helps him to sit up straight.

To attach the support pants, insert the buckles in the openings and secure them at the back with the clamping buckles.

Step 10: Make a fitting table

Make a fitting table

The table ensures extra stability for the child. The child can put his arms on the table and lean on it, this will make him sit up more straight by himself. He has to do some effort by himself with is better than a belt around his chest, because exercise is good for the child, otherwise he will get lazy which is bad for his muscles.

The table is made in the same style as the seat.

We used the multiplex. Dimensions:

– table leaf: 390x310x5mm
cutout for the belly: 260x150mm

– table legs: 310x210x5mm

To make the cutout for the belly, measure the waist of the child and see for yourself what the best measurement is for your child.

To put the table together, we used the same technique as the seat so we drill holes in the planks 20 mm of the borders. The holes are drilled 30mm from each other. For the plank, also drilling 20mm from the border and 30mm from each other.

For stability, we attached 4 laths again on the side planks, on each side plank, two laths. This laths are 18x15x310mm.

The planks are fixed to each other with rope again, we will do this in the same way as we did with the seat.

The loop that can be seen on the pictures has been stitched out of the skai and attached with staples onto the middle plank. This loop can be attached onto the support pants. This ensures that the table can’t be pushed away by the child while he is playing. This gives extra safety.

Easy-Bin Wheelchair Aid

November 25, 2015 in Solution

An aid to assist wheelchair users when taking out the bin

The Easy-bin wheelchair aid is an simple but effective solution to taking the trash out for people in wheelchairs. It allows the user to take the trash out while still having full control of the wheelchair and being able to navigate tight spaces with ease.

Research has shown us that wheelchair users who live fairly independently find it hard to take out the rubbish.  This is because you need two hands to push a wheel chair so it is hard to push it whilst carrying a bin or bag, plus few people want to rest their rubbish on their laps. We were able to speak to man living in America, who makes a variety of YouTube videos showing his daily struggles, about how he takes out his trash. He was able to give us insight on how to develop a product which solves this issue.

The final solution we have come up with is a combination of arms and hinges which are permanently attached to a dustbin and then lifted up and attached to a wheelchair. The arm has the ability to fold up against the bin and clip into place, this keeps the product compact and out of the way. When the user wants to take out the trash all they do is simply go to the dustbin, unclip the first arm, lift the bin up and slot the arm into the attachments on the wheelchair, they can then twist the bin around in front of their legs.

To test the product we made a model and once was made we acquired our wheelchair and began to test our final outcome. The process of utilising our product starts off with the user travelling towards the bin lifting it up and clipping the bar in the clips attached to the wheelchair. Connecting the bar to the clips wasn’t a smooth process when we tested it but it was a simple process. Baring in mind we intend to make the actual product out of a metal such as aluminium because metals tend to have a more polished surface finish, so there would be less friction between the bar and the clip. Therefore connecting the pieces together should be a smother process.

Picture1 Picture2 Picture3  Picture4Picture5 Picture6

Finally we tested if you could utilize the wheelchair with our model attached. Because the bin can placed in front of the user it doesn’t cause much of an obstruction. We discovered the wheelchair was still usable with our attachment on and the performance of the wheelchair seemed the same as before which is dependent of the users physicality.


This product uses material and components that are easy obtainable from any hardware or DIY store. This means that actually making the product is simple because it mostly involves attaching components in various ways.

For a dustbin with dimensions of: 600mm x 400mm x 400mm

The size of the product is very dependent on the size of the dustbin and wheelchair being used. These three components are the most varied and would need to be adjusted. The rest of the components would be bought in as standard parts.

How to make a handle for roll on deodorant

Step-by-step instructions; how to make a handle for roll on deodorant. Useful if it’s difficult to grip the bottle or hold it at the angle needed to get the deodorant in the right place. This handle could also be useful for other household tasks because of it’s simple clip holder. If you discover another use take a picture and share your tips in the comments!




  • Pliers
  • Junior hacksaw



  1. Insert the threaded rod into the hole in the tool clip. Use one nut on either side to secure it in place, tighten with the pliers if necessary.


2. Mix a small amount of epoxy glue and cover each nut to make sure they won’t loosen over time. Leave to harden.

3. Use the pliers to bend the threaded rod into a curve. Test the handle with a deodorant bottle to find the correct angle to easily reach the underarm.

4. Trim the threaded rod using the hacksaw if it is too long. People with smaller hands might find a shorter handle is easier to hold.


5. Use some of the lightweight air dry clay to mould the handle. Make a sausage shape and push the threaded rod inside. Use your hand to shape the clay and make the handle comfortable to hold. Use 2 small balls of clay to cover the sharp edges of the tool clip that could scratch. Leave everything to dry for at least 24 hours. (Don’t dry in the microwave because of the metal parts!)


6. Paint the handle with acrylic paint or spray paint to make it wipe-clean. The clay is porous before painting. Here are just a few ideas:


7. To make the handle more ‘grippy’ dip it in Plasti-Dip and leave to cure.

8. The handle is ready to use! Slip the tool clip over the thinnest part of the deodorant bottle, take off the lid and put some on!

uWalk – Design walking aid which also doubles up as a tricycle for children aged 4-8 who have Cerebral Palsy.

November 19, 2015 in Solution



The Final Product

We have redesigned a walking aid for children diagnosed with Cerebral Palsy. We have focused on the age range of 4 – 8 years old. The aim of this product is to provide help to the children with the condition in everyday mobility difficulties. We understand that there are currently a wide range of successful mobility devices for this condition however, we found these products not be user friendly or aesthetically pleasing.  For this reason we redesigned the cerebral Palsy walking frame and chair, and incorporated a tricycle to allow the user to cycle. This is a common therapeutic hobby for children with cerebral palsy, so we thought it was an appealing and necessary element to add to the product.

Features and Functions

The final product is displayed in the image to the left. The product is constructed from 5-layer plywood. Using plywood provides many benefits to the products function. Not only is it widely available, but also it is also durable and strong, meaning it can with stand the weight applied from the user. We decided to use specific plywood, which is bonded with a synthetic resin, as this then makes it waterproof.

The product includes adjustable seating to allow the user to change mobility methods, from walking to cycling. The purpose of this is to create a more suitable distance when the user wants to use the pedals. This is adjusted using the holes for the pegs that run down the main frame. The user will remove the pegs provided and align the seat in to the position that best suits the, before reapplying the pegs into the holes to secure into place.

The products steering works through a hinge system constructed using a sheet metal bracket that turns on a vertical axle. This is shown in the image displayed on the left. The joints on the image to the right are attached to the back of the front panel. These are handmade pieces, which are screwed to the surface of the front panel. A 3mm steel bar is then inserted through all the joints. Not only does this hold the two sections together but it also creates a pivot.

The gear system is what makes this product unique. It converts the product from a walking aid to a tricycle, simply by inserting pedals into the driver gear.

The cross sectional view on the image to the left shows how this mechanism functions. The gear on the left is the driver gear. This can be seen from outside the casing through the transparent ABS laser cut window. This is connected to the following gear with a bicycle chain. Both the driver gear and following gear are the same size with the same number of teeth. This means how many rotary motions the driver gear is turned, the following gear will turn the same amount of rotations. The back axle holds two fixed wheels on either side of the gear casing. This if for added stability and balance when the user is walking. The back axle is also fixed to the follower gear to allow the wheels to turn when the driver gear is moved with rotational movements from the pedals. This axle is made using 10mm steel tubing (hollow, wall thickness 3mm).  All wheels from this product are up-cycled children’s bicycle wheels. The front wheel of the product is an up-cycled child’s tricycle wheel. The actual wheel itself is not fixed to the front axle. Only the bearing section is attached. This allows the wheel to rotate without the axle turning. This was useful because the front frame has very little space to attach a rotating axle to. Instead the axle was bolted straight to the back of the frame. The front axle is made from 5mm steel. It was turned and cut on the lathe to get it to the correct thickness and length.

Anthropometrics and Data

Anthropometrics influenced the design majorly when looking at what shapes and sizes to use for the frame and wheels. We had to consider a number of aspects in the design and how they would vary depending on the users sizing. Looking at the highlighted area on the graphs to below, it indicated our target markets (4-8) average weight and height.

Manufacturing processes

Manufacture for the frame is relatively easy. This is one of the main benefits of using plywood, as it is so easy to machine. The main body, front panel and gear box casing are all laser cut from a sheet of five layered Plywood. A laser cutting machine uses less energy to run than most alternative methods, whilst still being efficient to maintain. They are also designed to run without human supervision making it very time effective. If a laser cutting machine is not available, the parts can be cut using a band saw. Both processes would still require a hand finish to the edges for safety precautions. Sheet bending is required to form the bracket that will join the front panel and the main frame together. A brake machine will be needed to accomplish the 90 degree angles needed. This part could be brought in but is cheaper to manufacture if the machine is available.

How the product suits the user

There are many things to consider when designing for a young child with Cerebral Palsy. Every child will have different weak points in their body and we must make sure they have the support needed to overcome said weakness.

The bike is low riding and features removable pedals. By removing the pedals we are making it easier to walk with the bike as a support system, the pedals would only obstruct the movement of the child. Having a lightweight support system with a seat means that when the child gets too tired from walking they can rest and sit. They could even sit while pushing themselves along.

On the pedals we have included a strap to secure the foot to the pedal. By doing this we making it easier for the child to continuously make a cycling motion without worry of trying to keep their foot on the pedals.

Due to it being a tricycle, and having three wheels, there is more stability than if it were just a bike with two wheels. This means that the child does not need to balance the bike; in fact the bike will provide balance for the child. Having this extra balance has mean that we can have pedals that the child straps into as there is no worry of them losing balance and toppling the tricycle.

The handlebars have to be appropriate for both cycling and walking. So we considered if it had to be extendable or not, and after taking anthropometrics into consideration we designed the correct distance for the user meaning there was no need for the extension.

The seat has to have the most support, requiring mainly lower back support. It is cushioned and padded in the required areas for maximum comfort and support. The seat is adjustable so that it can be put in five positions to suit the use, whether this is using the product as a walking aid or as a tricycle.

We have made sure that the tricycle has a very low centre of gravity and is extremely stable, this is highly important as if the child were to lose stability and lean, or become ridged it is important that the bike will not tip over. We want the user and their parents to have complete confidence in the aid.

From our research of existing products we saw that they all seemed very clinical and not very child friendly. To make our product more appealing to a young child we have chosen materials that can be coloured easily, making it available in many colours. We focused on primary colours initially to show how simple colours can make the bike stand out.

We are also hoping that as it is wood we could provide the child with stickers so that they can even personalise their bike, as it is wood the stickers could be easily sanded off and painted over if the child changed their mind on what they wanted on their bike. Our product encourages the child to walk from an earlier age, building muscles, flexibility and confidence. When muscle is built and exercised more often the child is less likely to have stiff muscles, which can be extremely painful.

“Physical therapy empowers the child physically and emotionally, and sets the stage for entering adulthood as an independent individual.” (What are the benefits of physical therapy?)
