Detachable Screen Key Structure with Internal Signal Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional keyboards with display screens suffer from exposed connecting lines affecting appearance and lack of user-replaceable display elements, making them inconvenient and aesthetically unpleasing.
Innovation Solution
A detachable screen key structure with a key signal connector housed inside the key body, allowing for signal transmission without external exposure and enabling users to replace display elements by docking and undocking the display butting element with the key butting element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the key signal connector is exposed outside the key, then signal transmission is achieved, but the overall appearance is affected
Solution Approach 1:
The key signal connector is nested inside the hollow portion of the key body, with its two ends respectively connected to the key butting element and circuit board. This nesting arrangement hides the connector within the key structure, eliminating external exposure and improving appearance while maintaining signal transmission functionality.
2Ease of operation
If the display element is fixed permanently, then signal transmission is reliable, but users cannot replace it themselves
Solution Approach 1:
The key structure is segmented into separable components: the display element with display butting element can be detached from the key body with key butting element. This segmentation enables users to replace display elements themselves while the butting elements ensure reliable reconnection through precise docking.
Solution Approach 2:
The butting elements (key butting element and display butting element) serve as intermediary docking mechanisms that facilitate both permanent connection during normal use and temporary separation during replacement. These intermediaries maintain connection stability when engaged while enabling user-replaceable functionality.
3Shape
If the key signal connector is placed inside the hollow portion, then appearance is improved, but the connector arrangement becomes more complex
Solution Approach 1:
The key signal connector is merged with the hollow portion of the key body, utilizing the existing internal space for connector placement. This merging approach integrates the connector into the key structure rather than adding separate external components, improving appearance while managing internal complexity efficiently.

AI summary
A detachable screen key structure mainly includes a key body having a hollow portion, key butting element and screen carrying element, where a key signal connecter is configured in the hollow portion, the screen carrying element is configured with a display element and a key cap is configured on the display element, and the display element is configured with a display butting element adapted to dock the key butting element. Whereby, a user can accommodate the key signal connecter for signal transmission inside the hollow portion so as to increase use beautification. Furthermore, since the display will be connected to the key butting element through the display butting element, the user is allowed to carry out the removal and replacement by themselves, which can increase use convenience.
