Circle Cross: Evolved a human body posture into a mechanical
structure of an arm chair.

OVER VIEW

Among all the common daily objects, I have a unique love for wooden furnitures. Based on my abundant crafting skills and human-centered design background, I am always interested in creating furnitures which can build intimate and meaningful connections with their users. Circle Cross is such an early attempt, an evolution from a smart human body posture to an imaginative arm chair.

INSPIRATION

All started with an experience of being rescued from a fall caused fracture

I was impressed by this interesting arm cross guesture used to transport victims, which reminds me of the mortise-tenon structure applied in traditional Chinese wooden furnitures and buildings,

Unlike other transferring ways relying on surrounding objects, this smart supporting method with stable mechanical properties, is formed just by inserting and overlapping arms.

It is so similar to the mortise-tenon connection used in wooden structures. Without glue and iron nails, wood components can be firmly assembled together by inlaying each other. All the freedom degrees of individual parts are limited, so as to construct a stable load-bearing structure.

So, why no evolve this arm gesture into a new type of wooden

mortise-tenon structure, and apply it to a chair design?

 

IDEATION

Evolve this human posture to a furniture form

Make it stabler to bear weight on the ground

Attach four legs to the core, develop it into a centrosymmetric structure

Size components to withstand maximum load

Using the mechanical analysis plug in Solidworks, the appropriate sizes of different components were verified to bear the maximum weight of 200kg
