Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple ambient conditions are simulated using separate test spaces, then measurement accuracy is improved, but test space requirements and device complexity increase
Solution Approach 1:
The patent combines multiple ambient condition simulations (different temperatures, lighting conditions, wireless signal environments) into a single integrated test space. The signal shielding box, lighting apparatus, and heating apparatus are merged into one system that can simulate various conditions simultaneously, eliminating the need for multiple separate test spaces while maintaining measurement accuracy
Solution Approach 2:
The test system is designed with multi-functional apparatus that can simulate multiple ambient conditions using the same physical space. The signal attenuation apparatus can create different wireless signal environments, the lighting apparatus can provide various illumination levels, and the heating apparatus can create different temperature zones, all within one test space, making the system universal for testing various operating conditions
2Productivity
If manual measurement methods are used for battery operating duration, then measurement simplicity is maintained, but productivity and measurement efficiency deteriorate
Solution Approach 1:
The measurement system automatically performs power consumption measurements without requiring manual intervention. The processor controls the various apparatus (signal attenuation, lighting, heating) and automatically records and calculates power consumption data, enabling the system to serve itself in conducting comprehensive tests and generating results, thereby significantly improving productivity
Solution Approach 2:
The system incorporates feedback mechanisms where the processor continuously monitors power consumption data from the power supplier and adjusts test parameters accordingly. The power monitoring apparatus provides real-time feedback on battery status, allowing the system to automatically determine when testing should conclude based on predefined criteria, enhancing both efficiency and accuracy
3Adaptability or versatility
If comprehensive ambient conditions are simulated, then adaptability of measurement system is improved, but device complexity and energy consumption increase
Solution Approach 1:
The measurement system is designed with dynamic adjustability where the signal attenuation ratio, lighting intensity, and heating level can be modified based on test requirements. The processor dynamically controls the various apparatus to create different ambient conditions, allowing the system to adapt to various testing scenarios without requiring fixed, complex configurations for each condition
Solution Approach 2:
The system achieves adaptability by changing physical parameters (signal attenuation ratio, illumination intensity, temperature) rather than requiring separate physical systems for each condition. By adjusting these parameters within the same test space, the system can simulate multiple ambient conditions while avoiding the complexity of building dedicated test environments for each scenario
