Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users find it inconvenient to adjust mouse resolution due to the need for software drivers or tools, which can be difficult to install and navigate, and there is a risk of losing the necessary software, making it challenging to change mouse settings.
Innovation Solution
An apparatus with a X-Y axis plane displacement detector and a switching circuit with switches, coupled to a mouse microcontroller, allows direct adjustment of mouse resolution without software, using switches to set resolution values based on sensed movement and direction, sending control signals to the computer for cursor movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If software driver or tool is used to adjust mouse resolution, then mouse resolution can be adjusted, but the operation becomes complex and inconvenient
Solution Approach 1:
The patent extracts the mouse resolution adjustment function from the software driver/tool environment and implements it directly in the mouse hardware through a switching circuit. This allows users to adjust resolution by simply toggling physical switches on the mouse itself, completely eliminating the need to install or navigate software drivers, thereby resolving the contradiction between ease of operation and device complexity
Solution Approach 2:
The mouse becomes self-sufficient by incorporating the switching circuit directly into its hardware. The mouse can independently adjust its own resolution settings through physical switches without requiring external software assistance. This self-service capability eliminates the dependency on software drivers and makes the adjustment process as simple as flipping a switch
2Reliability
If software driver or tool is used to adjust mouse resolution, then mouse resolution can be adjusted, but the risk of losing adjustment capability increases
Solution Approach 1:
The patent extracts the resolution adjustment capability from the software domain (which can be lost or forgotten) and embeds it directly into the hardware domain through a switching circuit. This hardware-based implementation ensures that the adjustment capability is permanently built into the mouse and cannot be lost, resolving the contradiction between reliability and potential loss of adjustment capability
3Adaptability or versatility
If multiple switches are used to set resolution, then more resolution options are available, but the device complexity increases
Solution Approach 1:
The patent segments the resolution setting function into multiple independent physical switches, where each switch controls a specific bit of the resolution value. This segmentation allows for multiple resolution options to be achieved through simple binary combinations of switch states, providing versatility while keeping each individual switch simple and the overall circuit manageable
Data Source
AI summary
An apparatus for setting multi-stage displacement resolution of a mouse is disclosed, which has a X-Y axis plane displacement detector, a switching circuit and a mouse micro controller. The X-Y axis plane displacement detector senses a distance and a moving direction generated by the mouse. The switching circuit has at least one switch. The mouse micro controller is coupled to the X-Y axis plane displacement detector and the switching circuit. The mouse micro controller sets the mouse resolution based on each switch, and responds to the distance and moving direction sensed by the X-Y axis plane displacement detector to provide a control signal to a computer connected to the mouse, thereby moving the mouse cursor on the screen of the computer, wherein the mouse cursor is moved based on the mouse resolution.
