Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If traditional external heating and temperature control equipment is used, then temperature control accuracy is improved, but device volume and cost increase
Solution Approach 1:
The patent integrates the temperature control module directly into the detection apparatus housing, merging the heating element, temperature sensor, and control circuitry into a single integrated unit. This eliminates the need for separate external heating equipment and temperature control devices, thereby reducing overall device volume while maintaining temperature control functionality.
Solution Approach 2:
The detection apparatus uses its own internal heating element and temperature sensor to control the temperature of the detection environment, rather than relying on external equipment. The system self-regulates temperature by sensing and adjusting using built-in components, making the system more compact and portable.
2Stability of the object's composition
If traditional external heating equipment is used, then temperature stability is improved, but cost increases
Solution Approach 1:
The patent combines the heating element, temperature sensor, and control circuitry into an integrated temperature control module that is built into the detection apparatus. This integration reduces the need for multiple separate components and their associated connections, thereby lowering manufacturing costs while maintaining temperature stability through coordinated control.
Solution Approach 2:
The system uses its own internal temperature sensing and heating components to maintain stable temperature conditions, eliminating the need for expensive external temperature control equipment. The self-contained design reduces overall system cost while achieving the required temperature stability for accurate image-sticking detection.
3Measurement precision
If traditional detection system is used, then detection capability is improved, but portability deteriorates
Solution Approach 1:
The patent integrates all essential detection functions including the image-sticking detection module, temperature control module, and signal generation capabilities into a single portable apparatus. This consolidation maintains full detection capability while enabling the system to be easily transported and deployed in different locations for real-time evaluation.
4Temperature
If external temperature control equipment is used, then temperature control range is improved, but system volume increases
Solution Approach 1:
The patent integrates the temperature control module with a range of heating capabilities directly into the detection apparatus housing. The heating element, temperature sensor, and control circuitry are combined in a compact arrangement that provides a wide temperature control range without requiring separate external equipment, thereby maintaining a compact system volume.
