Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual installation adjustment is performed based on operator experience, then sensor installation can be completed, but installation accuracy and efficiency are insufficient
Solution Approach 1:
The system enables self-service installation by having the sensor automatically detect biological information (respiration, heartbeat) and generate installation guidance information itself. The sensor serves both its detection function and the guidance function, eliminating the need for operator experience-based manual adjustment.
Solution Approach 2:
The system implements feedback by using the detected biological information to generate installation guidance information. The sensor detects actual biological signals, processes them to determine installation quality, and provides feedback guidance for improvement, creating a closed-loop installation adjustment system.
2Measurement precision
If biological information detection is performed continuously, then accurate detection is achieved, but energy consumption increases
Solution Approach 1:
The system employs periodic action by detecting biological information at specific intervals rather than continuously. The sensor performs detection cycles to acquire sufficient data for accurate biological information extraction while reducing overall energy consumption through intermittent operation.
Solution Approach 2:
The system applies parameter changes by adjusting detection parameters based on the acquisition environment and detected biological information. The sensor dynamically modifies detection intensity, frequency, and duration according to actual conditions, optimizing the balance between detection accuracy and energy consumption.
