Foldable Cycles TRIZ Cases

A scooter hinge joint uses an arc-shaped slot and guide pin to create a torque-free locking mechanism for secure folding.

A vehicle suspension system uses a rocker arm and universal damper structure to maintain wheel contact during turns.

An asymmetric main frame hinge pivots the front wheel inward to reduce the folded footprint, while a rear rack support stand provides self-support stability.

Segmented frame design with rotatable joints reduces storage volume while maintaining structural strength during riding.

A foldable bicycle frame uses a lower tube to form a triangle structure with the center and main beam tubes.

A two-stage quick-release structure connects foldable bicycle frames using an elastic hook and safety fastener.

Multi-axis hinge couplings pivot the scooter frame into a compact package, resolving the contradiction between small storage volume and adult ride comfort.

Pre-forming the arcuate flange prevents corrugation from excess fiber redundancy during bending, enhancing structural strength.

Deformable articulated quadrilateral frame enables longitudinal folding without disassembly, preserving comfort and stability of normal-sized wheels.

A dual-axis swivel hinge links front and rear frame sections to enable compact folding of two-wheel vehicles.

Nested seat tube and self-locking clamps resolve the contradiction between compact folded width and secure riding reliability.

Motor generates torque between frames when lever unlocks, eliminating high folding force.

A rotatable scooter seat unit transforms into a handrail via an elastic locking mechanism for compact storage.

Arc guide slots and positioning notches in a kick scooter folding mechanism enable efficient size reduction while maintaining connection security.

Skewed hinge axes on a folding bicycle enable rolling in the folded state, resolving interference between frame segments.

A scooter folding mechanism uses a return spring to drive a limiting piece into clamping slots for stable position control.

A one-person vehicle uses a pivot-mounted damper assembly to actuate control arm return.

A folding bicycle frame bypasses itself during collapse using a seat tube rotation axis and integrated fastening system.

A folding bicycle frame uses universal mounting interfaces to accept standard industry components.

Segmenting the front wheel assembly into two steerable units improves cornering stability, while a foldable frame reduces volume for transport.

Eliminates separate brackets by merging the fixing structure with the generator housing to resolve complexity and reliability contradictions.

Rotating top tube and down tube joints enable parallel wheel alignment, reducing storage volume while maintaining frame rigidity.

A compact electric bicycle pedal generator uses a planetary gear accelerating unit to increase rotational speed for efficient power generation.

A kick scooter wheel housing connects to the handlebar and includes a wall section that blocks foot contact with the front wheel.

A foldable electric scooter uses a retractable front hinge to pivot the steering column, enabling compact backpack transport.

Dual hinges rotate the rear wheel perpendicular then parallel to the footboard, while the steering bar collapses to reduce folded volume.

Segmented down tubes and pivoted joints resolve the contradiction between frame rigidity and folding complexity in foldable bicycles.

A folding bicycle frame uses a handle to drive simultaneous unlocking of hinge lock buckles for quick operation.

A foldable vehicle integrates a mechanical linkage with a synchronized locking system to coordinate head and chassis movement.

A folding bicycle uses a central hinge shaft and locking pin to pivot three frames for compact storage.
