Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a non-replaceable gas sensor is used in the electronic device, then the device structure is simple, but the sensor performance degrades over time and cannot be restored
Solution Approach 1:
The gas sensor is separated from the main device body and placed on a detachable tray, allowing the sensor to be replaced independently without affecting the rest of the device structure. This segmentation enables sensor replacement while maintaining overall device simplicity.
Solution Approach 2:
The sensor system transitions from a fixed, static configuration to a dynamic, replaceable one. The tray can be inserted and removed, allowing the sensor to be dynamically replaced when performance degrades, thereby maintaining reliability while keeping the replacement mechanism simple.
2Reliability
If the gas sensor is made replaceable, then the sensor performance can be maintained through replacement, but the device structure becomes more complex
Solution Approach 1:
The tray serves multiple functions: it holds the sensor module, provides electrical connections through contacts, and enables mechanical insertion and removal. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.
Solution Approach 2:
The electrical connection components are merged with the tray structure itself, rather than being separate elements. The tray's contact elements directly interface with the sensor module, combining mechanical support and electrical connection functions into a single integrated component.
3Measurement precision
If the sensor module includes separate components (sensor, chamber, pipe), then the gas analysis precision is improved, but the manufacturing complexity increases
Solution Approach 1:
The sensor module is segmented into distinct functional components: the gas sensor, sensor chamber, and pipe. This segmentation allows each component to be manufactured and tested independently, then assembled into a complete module that can be replaced as a unit, balancing manufacturing complexity with measurement precision.
Solution Approach 2:
The pipe is nested within or connected to the sensor chamber, which in turn contains the gas sensor. This nested arrangement integrates multiple components into a compact module that maintains precise gas analysis capability while reducing the overall footprint and simplifying the replacement process.
