Drawers TRIZ Cases

Rotary scroll-groove and thrust-groove adjusters let a sliding box move horizontally and vertically without unfastening the rail connection.

A pretensioned driver, pivotable lever, and retraction device keep drawers stably closed without precise installation and reduce impact noise.

An elastic snap-in rail coupling lets drawers lock securely yet be removed and reinserted without tools or component damage.

Receiving elements built into C-shaped guide rails let damping or self-closing units be pre-mounted, cutting installation effort and saving space.

A control cam in the pull-out guide enables push or pull opening while reducing emergency-opening effort, noise, and closure impact.

A single slide assembly combines locking, elastic closing, and push opening to cut drawer hardware count, assembly cost, and user complexity.

By merging locking and synchronizing functions into one member, this rail assembly cuts machining cost while keeping inner and middle rails moving smoothly.

A stepless adjustable ejection stop and magnetic coupling simplify drawer assembly while enabling precise panel gap adjustment and smooth closing.

A linearly adjustable engagement element lets drawers keep a stable push-out mechanism while enabling precise front-gap setting without removal.

Adjustable travel limiting balances ejection and pull-in forces in furniture parts, easing installation and improving closing alignment.

Rack end supports keep the toothed wheel engaged during drawer over-extension, preserving synchronization and stability without added mechanism complexity.

A shared speed-dependent brake shaft damps the final retraction of multiple furniture pull-outs, reducing impact and damage risk.

A gear-linked extension leg overlaps the lever in the closed position, cutting drawer ejector depth while preserving a longer contact path.

A variable-length ejector lever changes during motion to prevent kinking, improve torque transfer, and fit different furniture layouts.

A four-stage slide rail mechanism combines damping, pull-back, and push-out springs to lock drawers quietly and rebound them for easier reopening.

Mounting the ejection catch on the movable furniture part enables full-stroke spring recharging and automatic return to a fully closed state.

A retaining cursor blocks premature drawer closure until full opening resets the auto-closing mechanism for reliable manual reclosing.

An elastomer stop damper with a movable transmission part absorbs normal drawer loads and shifts high forces to an end stop to cut wear and save space.

Spring-elastic comb tongues lock drawer wall parts through simple openings, cutting component count, assembly force, and structural space.

A rack-and-gear coupling synchronizes drawer guide rails to prevent tilting, stabilize off-center opening, and simplify furniture assembly.

Spring-loaded side pegs and guide sections lock a drawer rear wall securely while allowing easy removal and tolerance compensation.

A spring-loaded cam and secondary energy accumulator cushion hard drawer-closing impacts, reducing latch stress without increasing guide space.

A combined bearing pin and height-adjustment fitting lets drawer front panels be mounted quickly and aligned precisely in both directions.

Bent tabs in a stepped drawer bottom edge let a thinner base resist assembly loads, increasing storage height without breakage.

A nested retaining pin and bearing part enable tool-free drawer alignment and gap adjustment without bulky mounting plates.

A compressible buffering member between the support base and rail stop softens drawer extension impact and cuts operating noise.

Tension-braced mounting elements clamp functional parts to drawer guide rails, resisting detachment forces while keeping movement aligned.

A locking actuator subassembly lets drawer guides add self-retraction later, avoiding welded mounts, corrosion issues, and extra production lines.

Clamped bearing elements secure drawer rail functional parts against detachment while supporting high forces, damping, and synchronized movement.

Spring-biased installation members lock into different rack hole shapes to prevent pin shifting, sliding, and inward retraction under vibration.

Dual springs, a hooking member, and synchronized rails enable one drawer slide assembly to self-open and self-close with smooth mechanical motion.

A spring-loaded piston retainer locks full-extension drawers against unintended opening and rebound while improving slide durability.

A folded support adapter converts standard slide modules into hidden drawer slides with better anti-droop strength and longer, smoother buffering.

A spring-loaded connection element returns to neutral after drawer removal, making tool-free reattachment easier and more stable.

A movable connecting element and rotary-to-linear adjuster enable sensitive, tool-free lateral drawer positioning with stable retention.

Preassembled spacer plates let one drawer guide fit different side wall thicknesses, cutting guide variants, assembly complexity, and cost.

A front-mounted bearing body with gear and eccentric adjustment lets loaded drawers be aligned from inside without widening the side frame.

An adjustable rear hook receiver lets drawer guide rails be aligned in height and side position without tools while keeping the furniture part secure.
