Adjustable Keyboard Mechanism for Variable Key Pressing Stroke
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing keyboards, whether membrane or mechanical, have fixed key pressing strokes that cannot be adjusted by users to accommodate personal operation preferences, limiting flexibility and comfort during use.
Innovation Solution
An adjustable keyboard design featuring a driving element, first and second plates, and keys, where the driving element rotates or slides to adjust the distance between the keys and the second plate, allowing users to change the pressing stroke through a mechanical adjustment mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the pressing stroke of the key is determined at the factory, then the keyboard structure is simple and easy to manufacture, but the user cannot adjust the pressing stroke according to personal operation requirements
Solution Approach 1:
The patent applies the dynamics principle by making the second plate movable relative to the first plate through guide portions that allow sliding adjustment. This enables the pressing stroke to be dynamically changed from a fixed factory setting to an adjustable parameter, resolving the contradiction between adaptability and device complexity by using a simple sliding mechanism rather than a complex adjustment system
Solution Approach 2:
The patent segments the keyboard structure into two separate plates (first plate and second plate) that can move relative to each other. The keys are mounted on the second plate which can be adjusted independently from the first plate, allowing the pressing stroke to be modified without affecting the overall keyboard structure, thus maintaining simplicity while adding adjustability
2Ease of operation
If the pressing stroke is fixed, then the manufacturing process is simple, but the user experience and comfort cannot be optimized for different users
Solution Approach 1:
The patent implements self-service by allowing users to independently adjust the pressing stroke according to their personal preferences without requiring manufacturer intervention or complex calibration procedures. The simple sliding mechanism enables users to easily modify the key position and pressing stroke, improving ease of operation while maintaining manufacturing simplicity
Solution Approach 2:
The patent applies parameter changes by allowing the pressing stroke parameter to be modified by the user through the adjustable mechanism. The physical distance between the key and the key opening can be changed to create different hand feelings, optimizing user comfort without complicating the manufacturing process

AI summary
An adjustable keyboard includes a driving element, a first plate, a second plate and a plurality of keys. The second plate is disposed between the first plate and the keys, wherein the second plate has a plurality of key openings and the keys are respectively aligned with the key openings. The driving element is configured to drive the first plate to move, and thus a plurality of first guide portions on the first plate respectively push a plurality of second guide portions on the second plate so as to move the second plate and adjust the distance between each of the keys and the corresponding key opening.
