Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a triboelectric generator is embedded in the tire to generate electric current for particle capture, then particle capture effectiveness is improved, but device complexity increases
Solution Approach 1:
The triboelectric generator is embedded within the tire structure itself, nesting the power generation component inside the existing tire. This integration reduces the need for separate external components and simplifies the overall system architecture while maintaining particle capture effectiveness
Solution Approach 2:
The triboelectric generator utilizes the natural rotation of the tire during vehicle operation to generate electric current, eliminating the need for an external power source. The system serves itself by converting the mechanical energy of tire rotation directly into electrical energy for particle capture
2Reliability
If a capture surface with electric field is used to attract tire particles, then particle capture effectiveness is improved, but energy consumption increases
Solution Approach 1:
The capture surface is powered by electric current generated from the tire's own rotation through the triboelectric generator, creating a self-sustaining system that converts mechanical energy directly into the electrical energy needed for particle attraction without external power input
Solution Approach 2:
The triboelectric generator produces electric current in periodic pulses corresponding to the rotation cycles of the tire, allowing the capture surface to receive intermittent power supply that is synchronized with tire rotation, reducing overall energy consumption compared to continuous power supply
3Reliability
If filters are attached to the capture surface to collect particles, then particle capture effectiveness is improved, but maintenance requirements increase
Solution Approach 1:
The filters are designed to be removable and replaceable components that can be easily detached from the capture surface after becoming saturated with particles. This allows for simple maintenance operations where used filters are discarded and fresh filters are installed, minimizing maintenance complexity
