Cutting time. 1:1 moch ups

Cutting time. 1-1 moch ups

I started to cut the board out. It took me a long time to find a peice of cardboard big enough to do the model out of.

My new puppy thought it would be extremely fun to continuously run over the board while i was on my knees cutting the board at 1 am.

This is the end product!










I will need to figure out all the angled cuts to get he concept to work perfectly out of x board!

Refinement!

Refinement!

I initially started with a simple concept but found a few vital errors. Thus i have slowly refined my design to accommodate these problems. this first step I took was folding the same pattern a differnt way to come up with a stronger outcome this is what i came up with!

Tww legs out two legs in!


After a bit of trial and error i found out that it was much more effective to put all four legs in the middle, this create a nice aesthetic finish as well.

Four legs folded inwards!



This is the problem! the legs keep poping out if there is no weight applied!


I still could lock the legs together effectively so I made more scale models to test many theories.



Locking the legs themselves together!!


Cross it off!! fail - to flimsy, doesn't sit flat!

Adding two tab s on angles off two opposite legs!





Putting a cap on the bottom face abf fliping hte whole model upside down!




This did work... but wasn't very sound! There was no way i could fit such a large one peice flat pack into the allocated cardboard size!


So I tried cutting the corners of the square based falt pack!



This looked quite appealing but didnt help the structure!

So I tried cutting two of the four corners off the flat pack!



This shape is really nice. I will use this shape for my final model. This also solves the cardboard restrictions. By cutting the corners it enables me to make the model tall enough to comfortably sit on!

OK locking system!
Placing a back on the base and slotting it through the two opposing corners to hold the model from opening up!


This worked unbelievable well! but the back rest is on the angle! S o the user would have to sit with the point between there legs. Not to bad tho!

Second attempt!

This didn't really worked and looks bad, because of the angle of the board it didnt stop one leg from comming out.






I think I will combine the two backrest locking systems for my final model!

Concept Development/Refinment

Concept Development and Refinement


I managed to remove cross off one of the concepts leaving me my simplistic concepts to refine and develop. This was the first one...


After making mock ups and doing some basic testing I realized that this idea however simple dosnt function to well. There is to much pressure on the top connection. It can be fixed but I think this idea would have to many problems to make of it worth it.

Mock Up...


Second Concept to develop, the flat pack stool...


This idea was one of my favorites, but again after doing some testing and creating some moch ups there were simple complications that occurred when translated into cardboard. The idea worked perfectly in all the paper trials but the extra weight/thickness of the cardboard create problems..


Once placed together the design wouldn't stay in shape unless constant pressure, however light, was enforced on top. This sketch explains...


After making a few adjustments to relieve the tention created inside the design, (in hoped to make it free standing) but no tweaks worked!! By accident, after making adjustments to one of the mock ups I took pressure off the mock up and it stood by itself, haha, but in a position I didn't fore see.....



But cutting off the corners it makes the model sit in a different position...



I didn't realize this at the time so I continued trying to get the previous idea to work by create larger gaps to try and release the tension inside...


Again the failed, haha, so I redid the cut off idea with better fitting dimensions...



This idea is still stronge but much more stable, and I can enlarge the design to allow 2 or even 4 people to fit on the chair. There are still a few problems...


This legs still want to slide out, I need to create a small change to the legs allowing them to sit in the correct position..... the battle continues!!!!
