Mouse Key Module Stopping Assembly for Accidental Press Prevention
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 the operating habits of different users can lead to unintended key activation.
Innovation Solution
A mouse device with key modules that can be switched between a pressable and non-pressable state using a stopping assembly, comprising an actuating screw and stopper, allowing users to selectively disable keys based on their usage habits, preventing accidental presses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional keys are added on both sides of the mouse 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
Solution Approach 1:
The keycap is designed to be dynamically adjustable between a pressable state and a non-pressable state through the stopping assembly mechanism. This allows the key's functionality to change based on user needs, resolving the contradiction by making the key structure adaptable rather than fixed.
Solution Approach 2:
The stopping assembly changes the physical parameter of the keycap by introducing a stopping part that limits the pressing distance. When the stopping part contacts the keycap, it changes the key's state from pressable to non-pressable, thereby adjusting the operational parameters to prevent accidental triggering while maintaining functionality.
2Adaptability or versatility
If keys are made always pressable to ensure full functionality, then the adaptability is improved, but harmful factors increase due to accidental key activation
Solution Approach 1:
The stopping assembly is pre-configured with a stopping part that can contact the keycap to prevent excessive pressing. This preliminary anti-action mechanism is ready in advance to counteract accidental key activation by physically limiting the keycap's movement before unintended input can occur.
Solution Approach 2:
The stopping part acts as an intermediary element between the keycap and the internal switch mechanism. It mediates the pressing action by providing a physical barrier that stops the keycap before it can trigger unintended inputs, thereby eliminating harmful factors while preserving key functionality.
3Object-affected harmful factors
If a stopping assembly is added to prevent accidental key presses, then harmful factors are reduced, but device complexity increases
Solution Approach 1:
The stopping assembly is segmented into distinct components: a stopping part integrated with the casing and a keycap. This segmentation allows the anti accidental-pressing function to be added as a separate module rather than redesigning the entire key structure, thereby limiting the increase in device complexity.
Solution Approach 2:
The stopping part is nested within the casing structure, and the keycap interacts with this nested component. By nesting the stopping mechanism within the existing casing rather than adding external components, the patent minimizes the increase in device complexity while still achieving the harmful factor reduction.

AI summary
A mouse device includes a casing, a key module and a stopping assembly. The key module includes a switch and a keycap. When the keycap is in a pressable state and the keycap is pressed in response to an external force, the keycap is moved toward the switch to trigger the switch. The stopping assembly is disposed within the casing and aligned with the key module. The stopping assembly includes an actuating screw and a stopper. The actuating screw is screwed into the stopper. While the actuating screw is rotated in response to a rotational force, the actuating screw is moved in a screwing manner, and the stopper is moved toward a region between the keycap and the switch. When the keycap is stopped by a first stopping part of the stopper, the keycap is switched from the pressable state to a non-pressable state.
