Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a sensor device using electromagnetic waves is installed to detect air properties, then measurement precision is improved, but device complexity and structural space requirements increase
Solution Approach 1:
The patent combines the generating device and diverting device into a single integrated sensor device unit. The generating device that produces electromagnetic waves and the diverting device that directs these waves through different path lengths are merged into one compact assembly, reducing overall device complexity while maintaining the capability for precise air property detection through multiple interaction sections
Solution Approach 2:
The patent employs a nested structure where multiple interaction sections are arranged within a compact sensor device housing. The interaction sections with different path lengths are nested within each other or arranged in a space-efficient configuration, allowing the sensor device to detect air properties at multiple locations simultaneously without requiring proportionally more space
2Measurement precision
If multiple interaction sections are provided to detect air properties at different locations, then measurement precision is improved, but volume of stationary object increases
Solution Approach 1:
The patent arranges multiple interaction sections in a three-dimensional configuration within the sensor device rather than extending them linearly. By utilizing vertical stacking or angular arrangements of the interaction sections with different path lengths, the device achieves multi-location air detection capability while minimizing the overall volume occupied by the sensor device
3Adaptability or versatility
If the generating device is positioned flexibly using a diverting mechanism, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent introduces a diverting device as an intermediary component that redirects electromagnetic waves from the generating device to different interaction sections. This diverting mechanism acts as a mediator that enables flexible positioning and multiple detection paths without requiring multiple separate generating devices, thereby achieving adaptability while controlling the increase in device complexity
