Keyboard Shielding Layer Conceals Heat Staking Protrusions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The aesthetic appeal of electronic keyboards is compromised by visible gaps and protrusions resulting from heat staking technology, which affects user experience.
Innovation Solution
A keyboard design incorporating a shielding layer with a black surface that extends over a through hole on the bottom plate, partially covering the protruding parts to conceal them and enhance aesthetics.

Engineering Contradiction Analysis
1Weight of moving object
If heat staking technology is used to replace screw and nut bonding, then the keyboard becomes lighter and thinner, but visible gaps and protrusions appear compromising aesthetics
Solution Approach 1:
A shielding layer is introduced as an intermediary component between the bottom plate and the key units. This shielding layer covers the gaps and protrusions created by heat staking technology, mediating between the functional requirement of lightweight construction and the aesthetic requirement for a clean appearance.
Solution Approach 2:
The shielding layer is designed with a black surface that matches the color of the bottom plate and key units. By using color matching, the shielding layer becomes visually integrated with the surrounding components, effectively hiding the gaps and protrusions while maintaining overall aesthetic consistency.

If a shielding layer is added to cover gaps, then aesthetics are improved, but device complexity increases
Solution Approach 1:
The shielding layer is designed to serve multiple functions: it acts as a shielding component to cover gaps, provides structural support, and serves as a mounting surface for key units. By making the shielding layer multi-functional, the need for additional separate components is reduced, thereby limiting the increase in device complexity.
Solution Approach 2:
The shielding layer is integrated with the bottom plate through extension parts that extend toward through holes and overlap with black surfaces. This merging of components reduces the number of separate parts and simplifies the overall structure while maintaining aesthetic coverage.
3Shape
If the shielding layer extends toward the through hole, then gap coverage is improved, but manufacturing precision requirements increase
Solution Approach 1:
The shielding layer is designed with extension parts that pre-position themselves near the through holes before final assembly. This preliminary positioning action ensures that the shielding layer will cover the gaps without requiring high-precision positioning during the final assembly process, thereby reducing manufacturing precision requirements.
Solution Approach 2:
The shielding layer extends partially toward the through holes but does not require complete coverage. The extension part is designed to overlap with the black surface area, providing sufficient gap coverage without requiring precise alignment with the through hole boundaries, thus reducing manufacturing precision demands.

AI summary
The disclosure provides a keyboard including a bottom plate, a key unit and a shielding layer. The bottom plate includes a through hole. The key unit is disposed on the bottom plate. The shielding layer covering a portion of the bottom plate includes a main part and an extension part extending from the main part toward the through hole. The shielding layer is provided with a black surface, and an orthographic projection of the key unit on the shielding layer overlaps the black surface.
