Mouse Button Elastic Element Eliminates Empty Travel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mouse devices experience an empty travel distance between the pressing structure and the triggering part, leading to delayed signal generation and impaired tactile feedback when a button is pressed.
Innovation Solution
Incorporating an elastic element between the contacting portion and the upper casing, which is in contact with the switch module, allowing for immediate triggering of the switch module and enhanced tactile feedback by eliminating the empty travel distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional button structure with a gap between the pressing structure and triggering part is used, then the device structure is simple, but the switch module cannot generate control signal promptly and tactile feel is impaired
Solution Approach 1:
An elastic element is introduced as an intermediary component between the pressing structure and the triggering part. This elastic element maintains continuous contact with both components, eliminating the gap while allowing the button to pivot smoothly. When the button is pressed, the elastic element immediately transmits the force to the triggering part, ensuring prompt signal generation and providing responsive tactile feedback to the user.
Solution Approach 2:
The elastic element is pre-installed and pre-compressed between the pressing structure and the triggering part before the button is pressed. This preliminary positioning ensures that there is no empty travel distance when the button is activated, as the elastic element is already in contact and ready to transmit force immediately upon pressing.
2Reliability
If the elastic element applies excessive force to maintain contact, then the contacting portion remains in contact with the switch module, but the button becomes difficult to press
Solution Approach 1:
The elastic element is specifically designed with controlled elastic properties, including appropriate material selection and dimensional parameters, to provide just enough contact force to maintain continuous contact between the pressing structure and the triggering part. This optimized parameter configuration ensures reliable signal transmission while keeping the button pressing force within comfortable limits for the user.
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 elastic element ensures prompt signal generation and improved tactile feedback by maintaining contact with the switch module without excessive force, reducing the empty travel distance and enhancing user experience.
Implementation Method 1
The elastic element is arranged between the contacting portion and the upper casing. Moreover, two ends of the elastic element are respectively contacted with the contacting portion and the upper casing. Consequently, the contacting portion is in contact with the switch element.

AI summary
A mouse device includes a lower casing, a circuit board, an upper casing, a button and an elastic element. The switch module is disposed on the circuit board. The circuit board is located over the lower casing. The upper casing has a slot. The upper casing and the lower casing are combined together. The button includes a push structure. The push structure includes a contacting portion corresponding to the switch module. The push structure is penetrated through the slot. The button is pivotally coupled to the upper casing. Consequently, the button is permitted to be swung relative to the upper casing. The elastic element is arranged between the contacting portion and the upper casing. Moreover, two ends of the elastic element are respectively contacted with the contacting portion and the upper casing. Consequently, the contacting portion is in contact with the switch element.
