Probably you will know them, the standing lamps with a switch on the floor which are handled by feet. Well, if you thought it would be easy to handle them by everyone, you got it wrong anyway! This easy DIY product is specially designed for people who use trained dogs to help them in daily life. The problem was that the dog couldn' t push the button very well, therefor this lever system is the solution.
Another advantage of this specific product is that it can be handled very easly by the dog, people who sit in a wheelchair and older people.
This project is developed by four industrial design students from the University of Ghent, Belgium.
Step 1: Materials & Tools
If you want to see how we made the product, just look at this movie "Hoe te bouwen".
Step 2: Laser all the wooden components
In this step we are going to laser all the parts made out of wood.
What you need for this step:
1. Download the illustrator file
2. Print file to lasercutter make shure that the file is in the right properties to laser:
- RGB color mode
- For cutting: R = 256, G = 0, B = 0
- For etching: R = 0, G = 0, B = 256
- Line thickness: 0,025mm
3. Let the laser machine do his job!
Step 3: Make the box
After the parts are laser cut we can assemble the box.
To make this box you need following components:
02, 03, 04, 05, 06 and 07 (Ref. to material overview step1)
tools you need:
1. Glue part 03 and 04 on to part 02. (Clamp the two pieces good to each other!)
2. Glue the lever together.
3. If the glue is dried from part 03, 04 and 02, knock the side panels (06) into the bottom plate with the hammer.
Note: Use another piece of (wasted) plank to knock on so you don' t damage the good planks
4. Knock the other side panels (05) into 06.
5. The box is now ready, the lever is also dry enough to glue the button piece (07) on it.
Step 4: Pour the concrete
In this step we will show you how to make the concrete block. This block has as purpose to give counterweight to the moment that the dog/person generates when pushing the lever. This is the beautiful, cheap and clean solution, feel free to use other heavy objects instead of pouring the concrete.
You will need for this:
1. Mix the concrete: use 3 units cement in proportion to 1 unit water. Use the stick to mix the water and the cement. (search for a stick with a rectangular section, this is better than a cilindrical stick)
Note: It' s easy to use one cup for the water and the other for the cement, then pour the water with the cement and mix it firmly.
2. After 1min30 you should get a fluid and homogeneous substance which you can pour into the box (see images).
3. Press the Cover (08) to the concrete on top so everything becomes closed. (We only did this because of easthetic reasons. You can leave away this cover if you like the view of concrete.)
Step 5: Make the axis
Now we are going to make the most important part of the product: the lever system and the axis.
For this step you will need:
1. Cut the aluminium tubes:
The 13mm diameter tube has a length of 150mm
The 16mm diameter tube each has a length of 57mm
2. Assembly the axis in following order:
Step 6: Finishing
Last but not least: finishing of the product.
What you will need for this step:
1. Stick the Antislip dots at the bottom side of the bottom plate. We did each in one corner.
2. Secure axis with gluing the 2 cilindrical wood pieces at the side panels before the axis holes (09)
3. You can use sandpaper to remove sharp edges.
The product is now ready to use! Just put your switch in it and give it a good place at your house.
Step 7: Final result
As you can see our client can operate her lamp with or without her service dog. In short, we are convinced that this product can facilitate the life of our target audience and many others!
