Adjustable Mouse Click Force Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mouse devices have a fixed click force that cannot be adjusted, leading to wrist pain issues for users with varying strength levels, including elderly people, children, and heavy computer users, and existing adjustable solutions compromise tactile feedback and switch stability.
Innovation Solution
A mouse device with an adjustable click force mechanism featuring a button, switch, linkage element, plate body, supporting element, and adjusting element, where the supporting element moves to contact either the first or second fulcrum, altering the click force through a leveraged mechanism that maintains switch alignment and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the click force is increased to accommodate stronger users, then the button becomes more durable, but users with weaker strength (elderly, children, women) experience wrist pain and difficulty operating the device
Solution Approach 1:
The patent implements an adjustable click force mechanism that allows the button's resistance to be dynamically changed between at least two different force levels. This enables the device to adapt to different user strength levels, allowing stronger users to benefit from higher durability while weaker users can operate with reduced force requirements, thereby resolving the contradiction between button strength and ease of operation for diverse user groups
Solution Approach 2:
The invention changes the physical parameter of click force by providing multiple selectable force levels through an adjusting mechanism. By varying the click force parameter according to user needs, the system maintains button durability while accommodating users with different strength levels, including elderly people, children, and women who would otherwise experience wrist pain
2Ease of operation
If the click force is decreased to help weaker users, then ease of operation improves, but the button may become too weak for stronger users and regular use
Solution Approach 1:
The adjustable mechanism allows stronger users to select higher click force levels when needed, ensuring the button receives sufficient force for durable operation. Meanwhile, weaker users can select lower force levels for easier operation, resolving the contradiction by allowing the system to dynamically adapt to different user strength requirements rather than being fixed at a single force level
Solution Approach 2:
The button is designed to serve multiple user groups with different strength levels through the adjustable force mechanism. It functions as both a durable button for stronger users and an easy-to-press button for weaker users, achieving universality across different user populations without compromising either durability or ease of operation
3Adaptability or versatility
If the triggering switch is moved away from the button click position to allow adjustment, then click force adjustability is achieved, but the empty travel distance of the button increases and tactile feedback deteriorates
Solution Approach 1:
The patent introduces a linkage element as an intermediary component that connects the button to the triggering switch. This linkage mechanism transmits the button's pressing motion to the switch while allowing the switch to be positioned optimally for both tactile feedback and adjustability. The linkage element mediates between the button click position and the switch position, maintaining short empty travel distance and good tactile feedback while enabling click force adjustment through the supporting element's movement
4Adaptability or versatility
If the triggering switch is moved during adjustment, then click force adjustment is achieved, but the switch stability decreases and cable detachment risk increases
Solution Approach 1:
The patent extracts the adjustment function from the triggering switch itself and places it on a separate supporting element. The supporting element can be moved to different positions to adjust click force, while the triggering switch remains fixed in its optimal position. This separation allows adjustment without moving the switch, thereby maintaining switch stability and preventing cable detachment while still achieving click force adaptability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables customizable click force settings that reduce wrist strain while maintaining tactile feedback and enhancing switch reliability by minimizing the empty travel distance and preventing cable detachment during adjustments.
Implementation Method 1
The plate body includes a first fulcrum, a second fulcrum and a triggering part. There is a first spacing distance between the triggering part and the first fulcrum. There is a second spacing distance between the triggering part and the second fulcrum. While the button is pressed down and the linkage element is moved downwardly toward the triggering part, the triggering part is swung around the first fulcrum or the second fulcrum to push the switch

AI summary
A mouse device includes a button, a switch, a linkage element, a plate body, a supporting element and an adjusting element. A triggering part of the plate body is arranged between the linkage element and the switch. When the adjusting element is moved, the supporting element is correspondingly moved. Consequently, the supporting element is selectively contacted with the first fulcrum or the second fulcrum. While the button is pressed down and the linkage element is moved downwardly toward the triggering part, the triggering part is swung around a first fulcrum or a second fulcrum of the plate body to push the switch. Consequently, the switch is triggered.
