Two point subtraction

Two point subtraction



In this prototype I wanted to explore further the idea of shearing or subtracting away from an object, that's why I kept the cube as a further shape to explore as it was simple but could be extrapolated to create something cool. 

My handout of shear showed off just one straight cut through the near middle but I thought what happens if I were to slice down the middle from two points of cutting. This in the end gave be an "M" kind of shape. There was potential to this prototype because of the legs of the "M" potentially becoming some sort of base for my product.

I like how you can look at this prototype multiple ways or multiple orientation and it changes its purpose completely. That could be a possible development where I look at multiple purposes. 



In Order to keep the centre of the chair stable and strong I decided to go for a filling box kind of mechanism. As seen with my original joints where I explore the usage of "Stacking". The final solution of this was a strong top force down but a weak side force. This was a problem most because of its one way fill. It didn't have enough different orientation cardboard pieces. 

Also with the friction being a problem, difficulties in measurements were faced with the inside cardboard being too loose or too tight for the outside cardboard body which made stacking inside not very secure and could easily fall out.
























In this image you can see the connection types which I could bring forward into new prototypes. The use of folding was one not previous explored in my original joints. I thought if there was no broken pieces it would make the structure stronger as there would be not tabbing required and allows for a big of flex which is good for support. The key to creating a good fold I learnt was to coincidentally relating back to my spatial verb, to shear away some of the cardboard but not all to creating a slight weakness in that fold so it can be bent to create a fold. 

 Bending it one way will be easier than the other, but the one which is a lot harder usually comes out to be the cleaner one.

Exploration of Cardboard Joints

Joints Original sketches for potential joints Joint 1: Slotting This joint derives from the technique of interweaving two pieces of cardboard that slot into each other. There are two slots in each cardboard which if measured correctly would connect on top of each other and have a flush finish. Accuracy of measurement was crucial here for a finessed finish and also getting the right tab size effected how easily it would slot into the gap without it ruining the integrety of the cardboard material (bending or folding). That was a diffuculty with creating the model. As for the actual joint, i tried using an "x" shape first and it was strong only in the middle because there was only one point of intersection but the sides were flappy and weak and would have needed more support. Also a crucial part of using this one was balance, it needs to be equally weighted in order to be the most effective thats why getting the measurements accurate was a must. I then di...

Exhibition day!

EXHIBITION DAY Good points: Structure was strong and durable, could hold Kevin and others without any stress. It was comfortable and Tane said it was amazing craftsmanship.  Critique: Spatial verb could have been shown a little more as shearing means to be asymmetrical.

Scaling up and refining

Scaling up Refinement and Scaled up version of prototype 5 to outline key problems and give a better perspective This prototype brings into effect the shear amount of structure I will need to put into my design for it to hold up effectively. The side bits are very thin and not strong. You can see how weak the top of the slider is. Next time I will have to figure out where that will stop in order to make it really strong to be able to hold up a person. The amount of stress and force put onto that slider will force it to come off as shown in the next photo. Reinforcing on a horizontal was not such a good idea as it is very weak. The way to overcome this issue is to look back at my previous joinery such as the crossing one and figure out that it needs to be on a vertical line in order for it to be really strong and have structural integrity for not only me. The sliders with one are not strong, but as seen with various more holes, there is opportunity for mor...
