Keyswitch Module Movable Plate Horizontal Stroke Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional keyboards face challenges in reducing thickness due to varying dimensions of keyswitch modules, leading to increased design and manufacturing complexities, as they require different scissors-like connecting assemblies to accommodate different specifications, making it difficult to lower all keyswitches to the same height.
Innovation Solution
A keyswitch module design featuring a movable plate that moves horizontally between two positions, utilizing forcing structures to adjust the height of keycaps relative to a bottom plate, allowing keycaps to move between opening and closing positions, with the sum of distances and horizontal movements equal to the horizontal stroke, enabling uniform height adjustment of keyswitches of different specifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional keyboards use different scissors-like connecting assemblies for keyswitches of different dimensions, then each keyswitch can be accommodated according to its specifications, but the design costs increase and manufacturing tolerances become harder to control
Solution Approach 1:
The patent applies universality by designing a single standardized abutting structure that can accommodate keyswitches of different dimensions. The movable plate with统一的抵接结构 (standardized abutting structure) can lower keyswitches of various specifications to the same height, eliminating the need for different connecting assemblies for different keyswitch types.
Solution Approach 2:
The patent employs dynamics by introducing a movable plate that can shift horizontally to adjust the lowering distance. This dynamic mechanism allows the same abutting structure to adapt to different keyswitch specifications by adjusting the horizontal position, thereby achieving uniform keyswitch heights without requiring multiple fixed configurations.
2Length of stationary object
If the keyboard is designed to lower all keyswitches to the same height to reduce overall thickness, then the keyboard becomes more compact, but it becomes difficult to accommodate keyswitches with varied dimension requirements
Solution Approach 1:
The movable plate provides dynamic adjustment capability, allowing the keyboard to lower keyswitches of different dimensions to the same height by horizontally shifting the plate to appropriate positions. This resolves the contradiction between reducing thickness and accommodating varied keyswitch dimensions.
Solution Approach 2:
The patent segments the keyswitch lowering function into individual adjustable units. Each keyswitch can be lowered independently to the target height through the movable plate's horizontal displacement, allowing precise control over the final keyboard thickness while accommodating different starting dimensions.
3Adaptability or versatility
If multiple abutting structures with different shapes are designed to accommodate different keyswitches, then all keyswitch specifications can be met, but the manufacturing tolerances and assembly tolerances become even harder to control
Solution Approach 1:
The patent uses a universal abutting structure design that works with keyswitches of different specifications. This single standardized structure simplifies manufacturing and assembly tolerance control compared to multiple specialized structures, while still achieving specification compliance through the movable plate's adjustable positioning.

AI summary
A keyswitch module includes a bottom plate, a movable plate, a keycap, and a connecting assembly. The moving plate is stacked with the bottom plate and capable of moving between a first position and a second position relative to the bottom plate. The movable plate moves a horizontal stroke from the first position to the second position. The connecting assembly is operatively connected to the bottom plate and connected to the keycap. A forced portion of the connecting assembly is configured to be moved by a forcing structure of the movable plate to make the keycap move between an opening position and a closing position relative to the bottom plate. When the movable plate is located at the first position, the forcing structure and the forced portion are separated by a distance, and the keycap is located at the opening position.
