Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors are employed in a dynamic environment with electromagnetic emissions, then data communication can be achieved, but communication reliability deteriorates due to interference from electromagnetic emissions and other adverse factors
Solution Approach 1:
The patent introduces a twisted pair wire configuration as an intermediary transmission medium between sensors and microprocessors. The twisted geometry of the pair creates opposing electromagnetic fields that cancel each other out, serving as a mediator that protects against external electromagnetic interference while enabling reliable data communication in dynamic automotive environments.
Solution Approach 2:
The patent converts the potentially harmful electromagnetic emissions into a beneficial shielding effect by using the twisted pair configuration. The electromagnetic fields generated by current flow in opposite directions through the twisted wires create mutual cancellation, transforming the harmful interference into a protective mechanism that enhances communication reliability.
2Adaptability or versatility
If multiple sensors and components are integrated into the electrical system, then system functionality is improved, but hardware exposure to heat, vibration, and electromagnetic emissions increases
Solution Approach 1:
The twisted pair wire configuration serves multiple functions simultaneously: it provides electrical connection for data communication, electromagnetic shielding against interference, and mechanical flexibility to withstand vibration. This multi-functional approach allows the system to integrate multiple sensors and components without proportionally increasing exposure to adverse environmental factors.
