Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If temperature sensors and data transmission systems are equipped for each component to measure and transmit temperature data, then measurement precision of temperature profiles is improved, but device complexity and manufacturing cost increase significantly
Solution Approach 1:
The patent creates a virtual copy of the temperature measurement system through software simulation. Instead of physical sensors on each component, the system generates virtual temperature profiles by simulating thermal behavior based on usage sequences and thermal models, eliminating the need for extensive physical measurement infrastructure while maintaining measurement precision
Solution Approach 2:
The patent replaces the mechanical/physical temperature measurement system (sensors, transmitters, receivers) with a computational system that uses software algorithms to calculate and generate temperature profiles based on usage data and thermal models, substituting physical measurement with virtual simulation
2Reliability
If temperature sensors and data transmission systems are equipped for each component, then reliability determination accuracy is improved, but manufacturing cost increases significantly
Solution Approach 1:
The patent uses virtual copying to generate temperature profiles through simulation rather than physical measurement, allowing reliable reliability assessment without the high manufacturing costs associated with equipping each component with sensors and data transmission capabilities
Solution Approach 2:
The patent replaces expensive, permanent physical sensor systems with inexpensive computational models that can be rapidly deployed and modified, significantly reducing manufacturing costs while maintaining the ability to determine component reliability accurately
3Measurement precision
If comprehensive temperature measurement systems are implemented across all components, then data accuracy for reliability analysis is improved, but the system becomes less adaptable to different usage scenarios
Solution Approach 1:
The patent implements a dynamic system where virtual temperature profiles are generated adaptively based on actual usage sequences. The simulation model can dynamically adjust to different usage scenarios, component types, and thermal conditions, providing both data accuracy and versatility without the constraints of fixed physical sensor installations
