Building Braking Devices TRIZ Cases

A friction hinge uses a pneumatic regulating chamber to create directional resistance during pivoting.

A hinge device uses a slider and compressive coil spring to elastically support a pivotal lever.

Composite jamb liner combines extruded sealing tracks with wood filler to match window frame appearance.

Segmented linkage arm with dual assembly states compensates for depth offset when mounting on opposite hinge sides.

A slide rail section guides a slider maintaining surface-to-surface contact with the torsion bar, preventing partial wear from uneven hinge arm abutment.

An integrated door housing combines a bottom seal channel with a guide track, using an activator pin to engage soft close devices for controlled deceleration.

A damping device uses a movable blocking member to abut different damper parts, enabling variable stroke control.

A self-closing hinge integrates closing and hydraulic damping mechanisms within a single operating chamber for controlled door motion.

A hinge with a sliding plunger and elastic counteracting means controls door rotation between open and closed positions.

Integrated ratchet pawls on the brake disk prevent incorrect orientation during installation while enabling manual operation during power failures.

A vehicle armrest hinge uses a movable pin to toggle between locked and released positions for mechanical reset.

Housing channel and transmission align indicator with size indicia to resolve poor visibility of door closer adjustment settings.

A sliding door carriage uses a fin insert for anti-derailing and an internal fluid damper for soft closing.

Inclined coupling surfaces convert horizontal displacement into vertical movement for precise height adjustment.

External valve grips allow adjustment from any mounting position, eliminating the need for multiple device variants and reducing manufacturing complexity.

Reorienting the damper vertically aligns the pressure rod with the force axis, eliminating oblique forces that damage pistons and extend service life.

Gravity stabilizes the door at a partially open position, eliminating battery drainage from constant power draw and removing mechanical brake costs.

Extracting the damping mechanism into the movable hinge arm resolves space constraints while maintaining reliable noise reduction during closure.

Segmentation separates the bracket body from the plate during installation to resolve shipping assembly constraints.

A revolving door brake shoe assembly uses a nested tension spring to apply adjustable friction against a rotating drum.

Internal damping mechanism decelerates invisible furniture hinge movement, eliminating impact noise while preserving the flat fixed part dimensions.

Non-coaxial springs reduce installation space while maintaining wire tension, resolving the trade-off between compact linkage design and reliable operation.

A connecting rod links a vehicle hood to a frunk lid, converting pivotal motion into simultaneous lid opening.

A door drive lever mechanism moves an axle device into preset positions to simplify assembly.

Segmented sealing elements and an adjustable backcheck spring resolve fluid leakage and fixed force trade-offs in hydraulic door closers.

Segmented fastening and buffering prevent rattling noises and disengagement risks in motor vehicle hood stops.

Electromechanical constraint mechanism converts rolling friction to sliding friction on suspension rollers.

Segmented coil springs in a door hinge provide multistage damping, reducing the force needed to open the panel while ensuring reliable camshaft return.

An electromagnet repels a permanent magnet on a sliding door to counteract weight and reduce pulling force without complex sensors.

A spring-driven connecting element guides a curved sliding door along its path to ensure reliable automatic closure without electrical components.

Perpendicular surfaces on the stopper engage door stiles to limit off-axis movement and prevent binding damage in vertically hung bi-fold doors.

A floating compensation housing with a weighted channel encloses gas to manage hydraulic fluid volume changes, eliminating complex sealing requirements.

Asymmetric hinge shaft positioning suppresses rotation and tilting caused by a single-side damper, ensuring proper fitting without complex dual mechanisms.

An injection molded plastic spindle nut eliminates costly metal assembly steps while reducing noise and vibration in vehicle door drives.
