What Structural Principles Are Used in Folding Houses?

Folding houses rely on four core structural principles to achieve foldability,portability and structural stability,all designed to balance compact storage with quick deployment:
Hinged joint rotation
Hinges(metal/heavy-duty engineering plastic)connect foldable panels(wall/roof/floor)and load-bearing frames,enabling 90°/180°rotation for folding/unfolding—the basic mechanical principle for the whole structure’s deformation.
Scissor-type telescopic bracing
Telescopic scissor frames(steel/aluminum alloy)are embedded in the frame as auxiliary load-bearing structures;they stretch to form a stable triangular/square support system when unfolded,and retract to reduce volume when folded,preventing structural collapse under light loads.
Foldable frame nesting
The main load-bearing frame(light steel keel/aluminum alloy)is designed with a nested/overlapping structure;the main and secondary frames fold into each other,minimizing the overall size for transport/storage while ensuring the unfolded frame has sufficient rigidity to bear the weight of panels and daily loads.
Snap-fit locking fixation
After unfolding,spring-loaded snap locks,bolt fasteners or self-locking mechanisms lock the hinged joints and telescopic braces in place,converting the foldable"movable structure"into a fixed rigid structure,ensuring stability for short-term use(wind/light impact resistance).
In short,all principles serve to maximize compactness in folding state and structural stability in deployed state,with lightweight high-strength materials(aluminum alloy/light steel)matching the structural design to reduce overall weight and improve portability.
