Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If dry batteries are used to power the wireless mouse, then the mouse can operate wirelessly, but the batteries require frequent replacement due to high power consumption
Solution Approach 1:
The patent implements a self-powered mechanism where the wireless mouse generates its own electricity through an eccentric wheel mechanism. The user's hand movement causes the eccentric wheel to rotate, driving a generator that produces electrical energy to power the mouse's electronic components, eliminating the need for external battery replacement
Solution Approach 2:
The patent replaces the chemical energy storage system (batteries) with a mechanical energy conversion system. The eccentric wheel converts the user's mechanical hand movement into rotational motion, which drives a generator to produce electrical energy, substituting the traditional battery-based power supply
2Reliability
If dry batteries are used in the wireless mouse, then the mouse functions properly, but environmental pollution increases due to waste battery disposal
Solution Approach 1:
The self-powered eccentric wheel mechanism eliminates the need for disposable batteries, allowing the mouse to generate its own power from user movement. This prevents battery waste and associated environmental pollution while maintaining continuous functionality
Solution Approach 2:
The patent converts the user's natural hand movement (which would otherwise be wasted energy) into useful electrical energy through the eccentric wheel mechanism, transforming a potentially harmful disposal issue into a beneficial self-sustaining power source
3Loss of time
If a rechargeable lithium ion battery is used, then battery replacement is reduced, but the mouse requires frequent charging and cannot function without power source availability
Solution Approach 1:
The eccentric wheel generator enables the mouse to self-charge during normal usage. As the user moves the mouse, the eccentric wheel rotates and generates electricity that charges the internal capacitor, eliminating the need for external charging cables and making the mouse immediately operational without waiting for power source availability
