Construction Fastening Devices TRIZ Cases

A controller maintains electric display energization while a vehicle door remains unlocked.

Profiled drive rods establish line contacts with guide elements, reducing frictional forces and easing operation while accommodating tolerance variations.

A safety device uses a control sensor to keep the locking member secured even if the key cylinder is forcibly removed or destroyed.

Flexible push-pull cable drives latch mechanism while blocker pin physically constrains secondary lever to resist jimmying attempts.

A hook and recess engaging structure connects two electronic device casings through a precise gap between the hook end and the recess front edge.

A locking device uses a guide pin to block rod translation and prevent unauthorized access.

A movable support body retracts via a drive rod to clear the sash path during unlocking.

A spacer component supports hand levers in driving rod gears across large distances between the transmission housing and the sash web.

A vehicle door closure latch uses a lock lever cam to disconnect the inside release lever from the pawl during child-lock states.

Front-mounted input gear and step-up transmission resolve rebate space constraints while reversing rotation direction for conventional locking compatibility.

A vehicle latch uses a single switch to detect fork bolt and detent lever positions.

A window lock uses a mechanical adjusting mechanism to set torsion spring preload for different operating requirements.

Segmenting the lock into two parts eliminates tool-based assembly, reducing time and costs while maintaining reliable quarter-turn operation.

Spring-loaded latches resolve the contradiction between secure closure and user strain by enabling easy battery compartment access.

A combination lock uses a segmented bolt and latch mechanism to secure locker doors against frame bending attacks.

A locking part uses a tilted clamping plate to engage groove edges securely.
