Emergency Casings TRIZ Cases

Group IV oxide flame-retardant aids replace antimony trioxide in relay case resin, preserving thin-part flame resistance and environmental safety.

A protective button cover blocks accidental tact switch presses during handling, preventing power loss and preserving cordless lamp reliability.

Water pressure acting through passage holes and elastomeric material switches a pinpointer into underwater mode without button sequences.

A split PCB and centrally aligned single antenna shrink machine-guard safety switches while simplifying wiring and preserving reliable access locking.

A sliding head-to-case coupling removes extra screws, keeping machine-guard safety switches compact, stable, and resistant to mechanical loads.

A stepped housing bottom compresses the seal at the lead wire while preserving drainage, improving switch waterproofness in wet environments.

See-through slots let the upper and lower casings assemble vertically, easing demolding, cutting cost, and expanding keycap design freedom.

Sealed air chambers in a flexible keyboard circuit block liquid and cleaning-agent ingress while preserving tactile feedback and reliable operation.

Segmented sealed air chambers in a flexible keyboard circuit block liquid ingress while preserving tactile feedback and disinfection resistance.

Selective punching and cutting let one notebook keyboard frame switch between US, UK, and JIS layouts while reducing mold cost and inventory.

A stop plate constrains switch-member movement in a button assembly, preventing loosening after long use or drops and keeping each press effective.

A rupturable seal at the enclosure division interface reveals unauthorized opening or reconditioning of circuit breakers.

An insulated bolt and separate metal terminal keep current out of the stud, preventing bypass and broadening single-bolt fuse mounting options.

A flexible composite membrane spans between keycaps to block liquid and dust ingress while preserving key movement, alignment, and a clean keyboard surface.

An insulated bolt joined to a metal terminal keeps current out of the fastener, prevents bolt loss, and broadens single-bolt fuse connections.

A stepped housing bottom lets the seal block water ingress while draining trapped water, keeping opening detection reliable under water exposure.

A molded side-key sealing structure uses shaped protrusions and bracket support to improve waterproof adhesion, button feel, and assembly stability.

A replaceable elastic part in the keyboard shaft changes pressing resistance and sound feedback without swapping full switch modules.

Projections maintain a uniform housing-cover gap so adhesive flows evenly, preventing sealing failure in sealed electromagnetic relays.

Localized piezo actuators give thin non-actuating keys a mechanical click feel, improving typing speed and keystroke confidence.

An elastic waterproof film and foam partition replaces loose O-rings, simplifying button assembly while preserving water resistance and tactile feel.

An annular flexible support at the recess edge keeps a button film smooth under pressure, avoiding buckling, crease lines, and indentations.

A push switch substrate features a corner groove to enable effective pressing force transmission.

Integrated elastomer shaft eliminates separate water stop components, reducing assembly complexity while maintaining waterproof reliability.

Segmenting the top cover from an intact circuit board assembly allows cleaning without disassembling scattered components.

A push button switch uses a rotating tongue lever to drive movable contacts within a compact housing.

A detachable support mounts switches between a steering wheel and boss to enable repositioning.

Preliminary action aligns button assemblies with openings, and extraction hides fasteners to prevent wear on electronic device casings.

A trip cam engages the operating handle to reduce friction at component interfaces.

A magnetic sensor detects a button-mounted magnet to generate signals without mechanical contact.

A waterproof cover uses a translucent flexible dome to reveal the internal reset button when tripped.

A swivel actuating pressure switch uses a rotating shorting member guided by a fluted receptacle to close electrical circuits.

A circuit breaker integrates a movable terminal barrier into its housing to protect electrical terminals while maintaining a low profile.
