Input Device Fixing Module for Circuit Board Layout Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional electronic apparatuses with combined keyboard and optical mouse input modules face space constraints on circuit boards, limiting the layout area and necessitating larger device sizes due to the fixed positioning of these components.
Innovation Solution
The use of a fixing module with accommodating spaces on a circuit board allows for the positioning and fixing of input modules like an optical mouse, while also creating space for additional electronic components, thereby increasing the layout area and minimizing the device size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the optical mouse and keyboard are disposed on the circuit board using traditional fixed positioning, then the input modules can be properly positioned and fixed, but the layout area on the circuit board is limited and the device size increases
Solution Approach 1:
The input module is divided into separate functional components (optical mouse and keyboard) that can be independently positioned and fixed on the circuit board, allowing for optimized space utilization and independent routing of signal lines for each component
Solution Approach 2:
The patent utilizes three-dimensional space utilization by positioning the optical mouse and keyboard at different locations and orientations on the circuit board, employing multi-directional signal routing to maximize the use of available board area while maintaining compact device dimensions
2Ease of manufacture
If the circuit board size is increased to accommodate all electronic components, then all necessary components can be disposed, but the electronic apparatus size increases
Solution Approach 1:
The patent combines multiple input functions (optical mouse and keyboard) and electronic components into a single integrated circuit board design, consolidating what would traditionally require separate boards or housing into one compact unit, thereby reducing the overall device size while maintaining full functionality
Solution Approach 2:
The circuit board is designed to serve multiple functions simultaneously: it acts as the structural base, signal transmission medium, and mounting platform for both the optical mouse and keyboard, as well as housing for electronic components, eliminating the need for additional dedicated structures for each function
