Adjustable Mouse Button Structure for Tunable Click Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mice lack adjustable pressing force settings, leading to inconsistent user input and potential damage from magnetic connections that can cause buttons to separate from the mouse body upon impact.
Innovation Solution
A mouse design featuring a key structure with an elastic section and a pressing force adjusting component that allows users to change the location of a limiting portion, altering the lever arm length and thus the required pressing force, while also preventing accidental separation of the key housing through magnetic attraction and a flange mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the distance between the fixed end and free end of the button is increased to reduce pressing force, then the required pressing force decreases, but the button becomes more prone to accidental separation from the mouse body
Solution Approach 1:
The patent makes the fixed end position of the button dynamic and adjustable rather than fixed. The limiting portion can be positioned at different locations on the elastic section, allowing users to adjust the effective length of the button lever arm according to their needs, thus dynamically changing the pressing force requirement while maintaining secure connection.
Solution Approach 2:
The button structure is divided into separable components: the key housing, elastic component, and limiting portion. This segmentation allows the limiting portion to be independently positioned at different locations on the elastic section, enabling adjustment of pressing force without compromising the overall structural integrity and connection stability.
2Reliability
If the button structure is made more secure to prevent separation, then connection stability improves, but the pressing force required increases
Solution Approach 1:
The patent resolves this contradiction by making the connection stability mechanism dynamic. The limiting portion can be adjusted to different positions on the elastic section, allowing users to optimize between connection security and pressing force requirement based on their specific needs, rather than having a fixed compromise design.
3Ease of manufacture
If the button structure is simplified for ease of manufacture, then manufacturing cost decreases, but the ability to adjust pressing force is lost
Solution Approach 1:
The patent achieves adjustability through segmentation into simple, manufacturable components: key housing, elastic component, and limiting portion. Each component can be manufactured independently using standard processes, and their assembly creates the adjustable functionality without requiring complex integrated manufacturing.
Solution Approach 2:
The patent introduces dynamic adjustability through a simple mechanism where the limiting portion can be positioned at different locations on the elastic section. This dynamic feature is achieved through straightforward component design and assembly, maintaining ease of manufacture while adding versatility.
4Adaptability or versatility
If multiple positioning locations are added for the limiting portion, then pressing force adjustability improves, but device complexity increases
Solution Approach 1:
The patent implements multiple positioning locations by dividing the elastic section into distinct segments or zones where the limiting portion can be positioned. Each positioning location corresponds to a specific segment, providing discrete adjustability options without requiring complex continuous adjustment mechanisms.

AI summary
A mouse includes a main housing, a key structure, and a pressing force adjusting component. The key structure has a connecting end, a free end, and an elastic section. The connecting end is connected to the main housing, and the elastic section is located between the connecting end and the free end. The pressing force adjusting component is movably disposed on the main housing and has a limiting portion, and the limiting portion limits elastic deformation of the elastic section. A location of the pressing force adjusting component on the main housing is adapted to be changed to change a location of the limiting portion at the elastic section.
