Asymmetric Keyboard Key Structure for Correct Switch Triggering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional multiple key structures in mechanical keyboards face issues due to the deviation of force application and pivot points, leading to incorrect triggering of switch shafts, and the symmetrical design of balance shaft sleeve seats limits the structure and width, complicating manufacturing.
Innovation Solution
A key structure with asymmetrically designed balance shaft sleeve seats, allowing for different structures and widths on the left and right sides, enabling increased spacing between balance and switch shaft sleeve seats for improved design flexibility and correct triggering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If two balance shaft sleeve seats are injection molded with the same mold using symmetrical design, then manufacturing cost is reduced, but the structure and width of the balance shaft sleeve seat and switch shaft sleeve seat are limited
Solution Approach 1:
The patent applies asymmetry by designing the balance shaft sleeve seat with different structures and widths on the left and right sides. Specifically, the first balance shaft sleeve seat has a first width and the second balance shaft sleeve seat has a second width that is different from the first width. This asymmetric design allows each sleeve seat to be optimized for its specific position, providing greater structural freedom and adaptability while still being manufacturable with cost-effective methods.
2Adaptability or versatility
If the balance shaft sleeve seat is designed asymmetrically with different structures and widths on left and right sides, then structural freedom and design flexibility are improved, but manufacturing complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the balance shaft sleeve seat into distinct left and right portions (first balance shaft sleeve seat and second balance shaft sleeve seat) that can be manufactured separately or as modular components. This segmentation allows each portion to be optimized independently for its specific functional requirements while simplifying the overall manufacturing process through standardized production methods for each segment.

AI summary
A key structure may include a switch shaft sleeve seat and a switch shaft accommodated in the switch shaft sleeve seat, where an end of the switch shaft penetrates the switch shaft sleeve seat and is movable relative to the switch shaft sleeve seat; two balance shaft sleeve seats on sides of the switch shaft sleeve seat, where each of the balance shaft sleeve seats may include a sleeve body and a top of each sleeve body may include a through hole. Moreover, the key structure may include two balance shafts respectively accommodated disposed in the sleeve bodies, where top ends of the balance shafts penetrate the through holes. Also, the key structure may include a key cap arranged above the switch shaft sleeve seat and the two balance shaft sleeve seats and fixedly connected to the switch shaft and the two balance shafts.
