Transparent Key Module Assembly for Stable Layer Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transparent key modules suffer from inconsistent layer thicknesses leading to depression issues, alignment deviations, and potential damage to display panels due to pressing actions, affecting user experience and component alignment.
Innovation Solution
A transparent key module design featuring a top cover, elastic member, switch circuit, and base plate, with hooks and positioning recesses, ensuring stable assembly and alignment by clamping the contact point layer and switch circuit between the top cover and base plate, preventing depression and maintaining display panel integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the transparent key module uses a stack structure of multiple layers with inconsistent thicknesses, then the module can achieve transparent functionality, but the inconsistent thickness causes depression when pressed and potential damage to the display panel
Solution Approach 1:
The patent introduces a cushioning layer between the switch circuit and the display panel that is configured to cushion the pressing action. This cushioning layer prevents the pressing force from directly transmitting to the display panel, thereby avoiding depression issues and potential damage while maintaining the transparent key module's functionality.
Solution Approach 2:
The cushioning layer serves as an intermediary element between the switch circuit and the display panel. It mediates the interaction by absorbing and distributing the pressing force, preventing direct contact between the key module components and the display panel, thus solving the depression and damage problems.
2Device complexity
If the transparent key module lacks alignment design between different layers, then the assembly process is simpler, but position deviation occurs causing misalignment with the graphic image on the display panel
Solution Approach 1:
The patent incorporates alignment marks or positioning structures on the cushioning layer and other components before the final assembly. These preliminary alignment features guide the positioning of different layers during assembly, ensuring that components are correctly aligned with the graphic image on the display panel before permanent fixation.
Solution Approach 2:
The alignment marks or positioning structures are designed to automatically guide the correct positioning of components during assembly. The structure itself provides the alignment function through its geometric features, eliminating the need for external alignment tools or complex adjustment procedures.

AI summary
A see-through key module includes plural keycaps, an elastic member, a switch circuit and a base plate. The elastic member includes plural support parts, plural lateral parts and a lower part. The lower part includes a connecting region and a periphery region. The plural lateral parts are installed on the connecting region of the lower part. The periphery region is arranged around the connecting region. The periphery region of the lower part includes at least one positioning recess. The switch circuit is located under the elastic member. The base plate is located under the switch circuit. The base plate includes at least one hook. The at least one hook is penetrated upwardly through the switch circuit and inserted into the corresponding positioning recess. Consequently, the switch circuit is fixed between the elastic member and the base plate.
