Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each temperature detector is connected in parallel to a controller with wiring, then the controller can receive temperature data from multiple detectors, but the amount of wiring increases and the device size cannot be reduced
Solution Approach 1:
Multiple infrared temperature sensors are merged into a single integrated sensor unit that contains all sensor elements and their signal processing circuits. This consolidation eliminates the need for separate wiring connections from each sensor to the controller, as the integrated unit communicates through a single connection, thereby resolving the contradiction between maintaining detection capability and reducing wiring complexity
Solution Approach 2:
The integrated sensor unit serves multiple functions simultaneously: it houses multiple infrared temperature sensors for detecting temperatures at different locations, incorporates signal processing circuits for data acquisition and processing, and provides a unified communication interface to the controller. This multi-functionality allows the system to maintain comprehensive temperature monitoring while minimizing wiring requirements
2Adaptability or versatility
If a third temperature detector is added to monitor more areas, then the temperature monitoring coverage increases, but the wiring amount increases making it difficult to reduce size
Solution Approach 1:
Additional temperature detectors are integrated into the existing sensor unit rather than being added as separate wired components. The integrated design allows multiple sensor elements to coexist within a single housing, expanding monitoring coverage without proportionally increasing wiring complexity, as all sensors communicate through the unified interface of the integrated unit
3Area of stationary object
If temperature detectors are positioned away from the controller, then the detection coverage area increases, but more wiring is required connecting the detectors to the controller
Solution Approach 1:
Multiple temperature sensors are combined into a single integrated unit that can be positioned at an optimal location for maximum detection coverage. This consolidation allows the entire sensor array to be placed away from the controller without requiring multiple long wiring runs, as the integrated unit communicates through a single connection, thereby extending detection coverage while minimizing wiring length
