Legends TRIZ Cases
- Illuminated Push-Button Locking Assembly for Clear Switch State Indication
A light-guided locking assembly makes push-button switch states clearly visible while keeping the structure simple and cost-effective.
- Keyboard Key Module With Dual-Color Backlighting for Faster Key Recognition
Alternating key-module light colors helps users locate specific keys faster while keeping adjacent illuminated keys visually distinct.
- Membrane Keyboard Circuit Venting for Waterproof Keystrokes
A four-layer membrane circuit routes compressed gas through stacked channels to prevent trapped air, corrosion, and waterproofing loss.
- Middle-Illuminated Key Switch With Guide Core Light Path
A bottom-mounted LED and guide core route light through the button center, overcoming shielding while keeping switch travel accurate.
- Push Button Display Cover Locking Structure for Easy Replacement
Lock hooks, an alignment feature, and a retaining washer let push button display covers be swapped easily without losing fixed orientation.
- Key Switch Mechanism With Mid-Travel Contact and Tactile Feedback
A conductive spring makes contact before full dome collapse, speeding key response while adding tactile and audible feedback.
- Illuminated Knob Module With Annular Light Guide Structure
LEDs inside the knob module feed an annular light guide to illuminate the rotary encoder without increasing size for dim-use operation.
- Nested Keycap Structure for Wear-Resistant Character Layers
A nested inner-outer keycap protects the character layer from wear while cutting paint steps to improve manufacturing yield and efficiency.
- Integrated Membrane Keyboard Switch for Ultra-Thin Backlighting
By integrating switch traces and LED backlighting on one flexible substrate, this case cuts keyboard switch thickness while preserving press response.
- Multi-Level Button Backlighting With Ambient-Light Feedback
Differential LED intensities and ambient light detection keep selected and unselected buttons distinct under changing lighting conditions.
- Keyboard Light Guide Structure for Uniform Key Illumination
A light guide with reflection and extraction features redistributes LED output across a keycap to improve glyph visibility and reduce light leakage.
- Frameless Keyboard Shielding Structure for Hidden Through Holes
A membrane switch shielding portion covers through holes between keycaps, hiding the base plate while preserving key travel and keyboard aesthetics.
- Rocker Switch Illumination Layout for Precise Press Guidance
Two under-slot light sources alternate illuminated zones with switch position, making the correct press area visible in the dark.
