Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the imaging unit operates without temperature control, then the device complexity is reduced, but the manufacturing precision of workpiece detection deteriorates
Solution Approach 1:
The patent applies parameter changes by actively controlling the temperature parameter of the imaging unit to maintain it within a predetermined range. This involves monitoring temperature and adjusting heating or cooling operations to optimize detection precision without requiring complete redesign of the imaging system.
Solution Approach 2:
The patent implements feedback control by continuously monitoring the temperature of the imaging unit and adjusting temperature control operations based on the measured values. The system compares actual temperature with the predetermined range and activates heating or cooling only when necessary, resolving the contradiction between precision and complexity.
2Manufacturing precision
If temperature control operations are performed frequently, then the manufacturing precision is improved, but the productivity decreases due to increased cycle time
Solution Approach 1:
The patent applies periodic action by controlling temperature adjustments to occur only when the temperature exits the predetermined range, rather than continuously or frequently. This periodic intervention maintains detection accuracy while minimizing interruptions to the work cycle, thereby preserving productivity.
Solution Approach 2:
The system performs self-service by automatically monitoring and adjusting its own temperature without external intervention. The imaging unit's temperature is self-regulated within the predetermined range through automated heating or cooling operations triggered only when necessary, reducing manual involvement and cycle time extensions.
3Manufacturing precision
If the imaging unit is used immediately without warming up, then the productivity is improved, but the manufacturing precision deteriorates due to temperature instability
Solution Approach 1:
The patent applies preliminary action by performing warming-up operations only when the temperature is below the predetermined range before detection operations begin. This ensures the imaging unit reaches optimal temperature conditions in advance when needed, rather than always requiring full warming periods, thus reducing time loss while maintaining precision.
Solution Approach 2:
The system applies dynamics by adaptively adjusting the warming-up operation based on the actual temperature conditions. Rather than applying a fixed warming-up procedure, the system dynamically determines whether warming is needed and adjusts the operation accordingly, optimizing both precision and time efficiency.

AI summary
An apparatus including a temperature acquisition unit that acquires a temperature measured by a temperature sensor; a temperature determination unit that determines whether the temperature acquired by the temperature acquisition unit at the time of executing the detection operation for work is within an allowable range determined in advance in order to ensure the accuracy of the detection operation; and a temperature regulation unit that executes a warm-up operation for raising the temperature when the temperature determination unit determines that the temperature is lower than the lower limit of the allowable range, and executes a cooling operation for lowering the temperature when the temperature determination unit determines that the temperature is higher than the upper limit of the allowable range.
