Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mechanical keyswitches lack flexibility in providing adjustable tactile feedback, requiring users to replace entire keyboards or keyswitches to change feedback types, leading to high replacement costs and limited operational convenience.
Innovation Solution
A keyswitch design featuring a substrate, upper sleeve component, lower sleeve component, and recovering component that allows for adjustable actuation force, travel distance, and feedback modes through movable parts and concave/convex structures, enabling manual or automatic switching between different hand feeling modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional mechanical keyswitches are used, then the keyboard provides a fixed type of tactile feedback, but the user cannot adjust the feedback type without replacing the entire keyboard or keyswitches, leading to high replacement costs and limited flexibility
Solution Approach 1:
The keyswitch employs a rotatable lower sleeve component that can switch between multiple angle positions (first angle position, second angle position, third angle position) to dynamically change the tactile feedback characteristics. This dynamic adjustment mechanism allows the same keyswitch to provide different hand feeling modes (e.g., clicky, tactile, linear) without physical replacement, resolving the contradiction between adaptability and device complexity.
Solution Approach 2:
The keyswitch integrates multiple functions into a single component: it provides both the structural function of a conventional keyswitch and the additional function of adjustable tactile feedback through the rotatable lower sleeve. The lower sleeve can be positioned at different angles to achieve different feedback types, making the keyswitch universal for multiple usage scenarios without requiring separate keyswitches for each feedback type.
2Adaptability or versatility
If users replace keyswitches to experience different tactile feedbacks, then the tactile feedback type changes, but the replacement cost increases and operational convenience decreases
Solution Approach 1:
The lower sleeve component enables dynamic switching between different tactile feedback types by rotating to different angle positions. This allows users to adjust the feedback type conveniently during operation without the need to physically replace keyswitches, thereby maintaining ease of operation while providing variety in tactile feedback.
Solution Approach 2:
The keyswitch structure allows users to adjust the tactile feedback type themselves by simply rotating the lower sleeve component, without requiring professional intervention or replacement of parts. This self-service adjustment capability enhances operational convenience while providing access to multiple feedback types.
3Adaptability or versatility
If the lower sleeve component is rotated to different angle positions, then the gap between the lower sleeve component and substrate changes, but the recovering component length must be adjusted accordingly
Solution Approach 1:
The recovering component (spring) is designed to work in conjunction with the rotatable lower sleeve, where the spring length and pre-compression can be adjusted according to the selected angle position. This dynamic configuration allows the recovering component to adapt to different gap measurements, enabling multiple hand feeling modes while maintaining proper mechanical function.
Solution Approach 2:
The invention allows for parameter changes in the recovering component (such as spring length, wire diameter, or pre-compression force) to match different angle positions of the lower sleeve. By adjusting these parameters, the system can compensate for the changing gap between the lower sleeve and substrate, thereby providing different tactile feedback characteristics without compromising the mechanical reliability of the keyswitch.

AI summary
A keyswitch with adjustable tactile feedback is adjusted by an adjusting method. The keyswitch includes a baseplate, an upper housing, an upper bushing component, a lower bushing component, a keycap and a recovering component. The baseplate has an electrode module, the upper housing is disposed on the baseplate, the upper bushing component is movably disposed on the upper housing, the lower bushing component is movably located between the baseplate and the upper housing, and the keycap is connected to a connecting portion of the upper bushing component. The lower bushing component can rotate relative to the baseplate to switch between a first position and a second position. The lower bushing component has a first lateral surface and a second lateral surface with different shapes. The recovering component is disposed between the baseplate and the lower bushing component to upwardly push the lower bushing component.
