Movable Mouse Shell Switching Button Functions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computer mouse designs require complex methods or additional buttons to switch between left-handed and right-handed modes, affecting user experience and requiring time and knowledge to implement.
Innovation Solution
A computer mouse with a movable upper shell that electrically connects to different sets of pins to switch the functions of its buttons between left-handed and right-handed modes, allowing seamless operation for both left and right-handed users without the need for programming or device settings modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional mouse designs are used with fixed button functions, then the device structure remains simple, but left-handed users experience poor ergonomics and usability
Solution Approach 1:
The upper shell is made movable relative to the base through a hinge mechanism, allowing it to pivot between a first position (right-handed mode) and a second position (left-handed mode). This dynamic structure enables the button functions to be switched by simply moving the shell, transforming a static device into a dynamic one that adapts to different user needs without adding complex electronic switching components
Solution Approach 2:
The mouse is divided into distinct functional segments: the base containing the pins and electronic components, and the movable upper shell containing the buttons. This segmentation allows the button assembly to be physically separated and repositioned relative to the base, enabling independent configuration of button functions for different hand orientations
2Ease of operation
If software-based mode switching is implemented, then additional buttons are avoided, but users require time and technical knowledge to configure and switch modes
Solution Approach 1:
The mouse automatically detects the user's hand orientation through the physical position of the movable upper shell and self-configures the button functions accordingly. When the shell is in the first position, the first button performs function A and the second button performs function B; when pivoted to the second position, the functions are automatically swapped. This eliminates the need for manual software configuration or user intervention
3Adaptability or versatility
If multiple physical buttons are added for different modes, then button function versatility is improved, but the device size and complexity increase
Solution Approach 1:
The first and second buttons serve multiple functions depending on the position of the upper shell. In the first position, they perform functions A and B respectively; in the second position, they perform functions C and D respectively. This multi-functionality allows a compact two-button design to provide the versatility of a four-button mouse without increasing physical size or adding additional button components

AI summary
In one example, a mouse may include a base for movement along a horizontal surface, first and second sets of pins disposed in the base, and an upper shell movable relative to the base between multiple mode positions. The upper shell may include a first button and a second button. The first button and the second button may electrically connect to the first set of pins in a first mode position. The first button and the second button may electrically connect to the second set of pins in a second mode position to switch functions of the first button and the second button.
