Rotatable Keypad Covering Deformation Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotatable electrical connectors for detachable 2-in-1 laptops face issues such as deformation or peeling of leather materials due to long-term rotation and expose unsightly shaft structures, affecting the product's appearance.
Innovation Solution
A keyswitch device design featuring a main body with an engaging structure and a flexible covering layer, where the engaging structure is connected to the main body and protrudes into a recess, and includes a pivot and fixing portion to securely engage with the connection base, preventing deformation and exposure of the connection base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a leather material is used to cover the keyboard with a rotatable electrical connector, then the electrical connector can be rotatable, but the leather material may be deformed or peeled off from the keyboard surface due to pulling after long-term rotation
Solution Approach 1:
The patent extracts the rotatable electrical connector from the leather material covering, placing it on the keyboard surface instead. This separation allows the connector to rotate independently without causing deformation or peeling of the leather material, thus maintaining both rotatability and the integrity of the covering layer.
2Adaptability or versatility
If a rotatable-shaft type design is used with shaft structures on both sides of the base, then the electrical connector can pivotally connect with the keyboard, but the shaft structure can be seen through a gap between the keyboard and the electrical connector, affecting the product appearance
Solution Approach 1:
The patent introduces a base as an intermediary component between the keyboard and the rotatable electrical connector. The base is positioned within the keyboard structure, allowing the connector to pivot while the base itself remains hidden. This intermediary element enables the pivotal connection function while preventing the shaft structure from being visible through gaps, thus maintaining appearance quality.

AI summary
A method for assembling a keyswitch device includes: connecting a first covering portion to a surface of a first housing; connecting a second covering portion to a connection base comprising an engaging portion; rotatably engaging the engaging portion with an engaging structure; connecting the engaging structure to the first housing; and fixing a second housing to the first housing such that the first housing and the second housing constitute a recess communicating with the surface, wherein the engaging structure partially protrudes into the recess.
