Side-Key Mouse Structure to Prevent Accidental Presses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mouse devices with additional keys on opposite sides are not user-friendly due to accidental triggering, as they do not accommodate individual operating habits effectively.
Innovation Solution
The mouse device features key modules that can be switched between pressable and non-pressable states using a stopper mechanism, comprising a switch, elastic element, and keycap, allowing users to selectively disable keys based on their habits to prevent accidental presses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional keys are provided on both sides of the casing to enhance functionality, then the versatility of the mouse device is improved, but the ease of operation deteriorates due to accidental triggering of keys on the non-dominant side
Solution Approach 1:
The keycap is designed to be selectively removable from the elastic element, allowing the operational state of each key to dynamically change between pressable and non-pressable. This enables users to adapt the mouse configuration to their specific operational needs, preventing accidental triggering of keys on the non-dominant side while maintaining full functionality when needed
Solution Approach 2:
The key module is segmented into separable components: keycap, elastic element, and switch. This segmentation allows independent configuration of each key, enabling users to remove keycaps from keys they wish to disable while keeping other keys functional, thus resolving the contradiction between having all keys available and preventing accidental presses
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
This design enhances user convenience by preventing accidental key presses, allowing users to customize key functionality according to their habits, thereby improving the overall usability of the mouse device.
Implementation Method 1
an elastic element, and a keycap. The keycap is detachably connected with the elastic element

AI summary
A mouse device includes a casing and plural key modules. The plural key modules are installed on two opposite sides of the casing. Each key module includes a switch, an elastic element, a keycap and a stopper. The switch and the elastic element are disposed within the casing. The keycap is detachably connected with the elastic element. The elastic element is arranged between the keycap and the switch. When the keycap is in a pressable state and the keycap is pressed in response to an external force, the keycap is moved in a direction toward the switch and the elastic element is moved with the keycap, so that the switch is triggered by the elastic element. The stopper is detachably connected between the keycap and the elastic element. When the keycap is stopped by the stopper, the keycap is switched from the pressable state to a non-pressable state.
