Computer Mouse Spring Cushioning Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Long-term use of conventional computer mice leads to wrist fatigue and shoulder pain due to constant force application, with existing solutions struggling to provide adequate elasticity and smooth operation.
Innovation Solution
A computer mouse design featuring a spring-based cushioning system where the upper case moves up and down in response to gripping force, dispersing load and adjusting height, incorporating protrusion boxes, bosses, and springs for elastic support, allowing smooth operation and reduced strain on the wrist.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mouse is held and force is applied thereto, then the upper case is resiliently moved up and down by a spring, but the mouse cannot provide flexible elastic force due to force applied to the wrist, so that smooth operation is difficult
Solution Approach 1:
The mouse is divided into an upper case and a lower case that can move independently. The upper case contains the spring mechanism and can move vertically relative to the lower case, allowing the elastic force to be isolated and controlled separately from the wrist application force, thereby enabling smooth operation while maintaining flexible elastic response
Solution Approach 2:
The spring mechanism provides dynamic elastic force that automatically adjusts to the force applied to the wrist. As the user applies force, the spring compresses and provides proportional resistance, creating a dynamic adaptive system that maintains smooth operation across varying force levels
2Reliability
If the mouse is manipulated in a state of being wrapped around the user's palm, then the mouse can be held securely, but excessive force may be applied to the wrist, causing wrist fatigue and shoulder muscle pain
Solution Approach 1:
The spring mechanism is pre-installed between the upper and lower cases to provide cushioning before excessive force is applied. When the user grips the mouse, the spring immediately begins to compress, absorbing force and preventing it from being transmitted directly to the wrist and shoulder, thereby preventing fatigue and pain while maintaining secure holding
3Device complexity
If the mouse height is fixed, then the structure is simple, but the mouse cannot adjust to different gripping forces, leading to muscle stiffness and fatigue
Solution Approach 1:
The mouse incorporates a dynamic spring mechanism that allows the upper case to move vertically in response to gripping force. This simple dynamic structure automatically adjusts the effective height and firmness of the mouse based on user input, providing muscle fatigue resistance without complex control systems or multiple components
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
The mouse effectively alleviates wrist fatigue and shoulder pain by dynamically adjusting height based on gripping force, absorbing impact and enabling smooth operation without straining the wrist, with a simple and manufacturable design.
Implementation Method 1
springs supported by the protrusion boxes are inserted into the bosses, so that the lower sides of the bosses are not separated from the protrusion boxes. When force is applied to the upper case, the upper case bounces due to the springs.

AI summary
The present invention relates to a mouse for a computer, which is a computer input device. The mouse has an upper case with a vertical cushioning function against force imposed on the mouse, and thus can operate smoothly. The present invention provides a cushioning function to a mouse, thereby eliminating fatigue and muscle pain of the wrist and fingers even when a user uses the mouse for a long time. The mouse is manufactured by assembling an upper case and a lower case, and is configured such that a protrusion box which protrudes upwards is formed on the lower case, a boss is fixed on the lower side of the upper case and penetrates the protrusion box, thereby being joined with the same, and a spring which is supported by the protrusion box is inserted into the boss from the outside while the lower side of the boss can be prevented from being separated from the protrusion box.
