Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wireless temperature sensor is used for testing, then the ease of operation and productivity improve due to rapid installation and removal, but the device complexity increases due to wireless communication requirements
Solution Approach 1:
The patent replaces wired mechanical connections with wireless communication technology. The wireless temperature sensor transmits data remotely without physical cables, eliminating the need for complex wiring while maintaining measurement functionality. This substitution directly improves ease of installation and removal while the wireless technology itself manages the complexity through integrated communication protocols.
2Measurement precision
If the wireless temperature sensor is placed in close proximity to the cargo space temperature sensor, then the measurement precision improves for accurate comparison, but the ease of operation decreases due to limited installation space
Solution Approach 1:
The patent employs a flexible mounting system that allows the wireless temperature sensor to be dynamically positioned at optimal locations. The sensor can be attached to various surfaces within the cargo space using adhesive pads or magnetic mounts, enabling operators to place it in close proximity to the cargo space temperature sensor when needed for accurate comparison, while still allowing easy removal and repositioning when installation space is limited.
