Finger-Worn Optical Mouse With Surface-Actuated Clicking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mouse devices are large and inconvenient to carry, requiring hand movement between the keyboard and mouse, which increases the risk of Carpal Tunnel Syndrome and hinders comfortable use.
Innovation Solution
A wireless ring mouse design featuring a housing, optical module, movable member, and switch element that detects displacement on a surface, allowing for cursor control and button functions without hand movement, with a compact and portable form factor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a conventional mouse device is used, then mouse operations can be performed, but the device is large and inconvenient to carry
Solution Approach 1:
The patent divides the traditional mouse functionality into segments: the optical tracking module is separated from the button module, allowing the tracking portion to be miniaturized for finger-wearing while the button functions are distributed or integrated in a compact manner. This segmentation enables the main tracking body to be small and portable while maintaining full mouse operational capability.
2Ease of operation
If a regular mouse device is used, then cursor control is achieved, but hand movement between keyboard and mouse is required
Solution Approach 1:
The patent merges the keyboard and mouse functions into a single integrated input device that can be worn on the finger. The optical tracking module and button modules are combined in one compact unit, allowing both typing and mouse operations to be performed simultaneously from the same position, eliminating the need for hand movement between separate devices and reducing carpal tunnel syndrome risk.
3Ease of operation
If the movable member protrudes from the housing to enable button press, then clicking function is achieved, but the device structure becomes more complex
Solution Approach 1:
The patent employs a movable member that can dynamically change its position - protruding from the housing when needed for button press operations and potentially retracting or maintaining a low profile at other times. This dynamic configuration allows the device to maintain operational capability while minimizing structural complexity and maintaining a compact form factor for portability.
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
Enables convenient and ergonomic use by allowing simultaneous typing and mouse operations with a single finger, reducing the risk of Carpal Tunnel Syndrome and enhancing portability.
Implementation Method 1
The optical module is configured to detect the displacement of the input device relative to a reference surface
Data Source
AI summary
An input device is provided, including a housing, a circuit board disposed in the housing, an optical module disposed on the circuit board, a movable member movably connected to the housing, and a switch element disposed on the circuit board. When the input device moves to a reference surface, the movable member contacts the reference surface, and the movable member is pushed by the reference surface to actuate the switch element.
