Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The night vision system in automobiles cannot be accurately calibrated after fault repair due to the absence of a target heating body, resulting in low accuracy.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a target heating body is used for night vision system calibration, then the calibration accuracy is improved, but the device cannot be provided after software or hardware failure
Solution Approach 1:
The patent creates a replaceable target heating body component that can be copied and substituted. The heating element with its specific shape and infrared emission properties serves as a calibration target that can be replaced after system failure, ensuring calibration capability is restored without requiring the original proprietary target body.
Solution Approach 2:
The calibration device is segmented into replaceable components: the heating element, the housing, and the target body. This segmentation allows the heating element to be independently replaced or repaired, maintaining calibration functionality even after software or hardware failures in other system components.
2Measurement precision
If a complex temperature control system is used to maintain precise heating element temperature, then the calibration precision is improved, but the device complexity increases
Solution Approach 1:
The patent implements a feedback control mechanism where a temperature sensor continuously monitors the heating element temperature and feeds this information back to the control unit. The control unit adjusts the power supply accordingly to maintain the target temperature, achieving precise temperature control through a relatively simple feedback loop rather than complex control systems.
