Solution Overview
Problem
Existing imaging systems using terahertz waves struggle with inconsistent positional relationships between illumination and imaging units, leading to suboptimal imaging results when the target area and imaging system components are not fixed.
Innovation Solution
An imaging system with a control unit that adjusts the operation of multiple illumination units based on real-time positional relationships with the target object, ensuring that terahertz waves are effectively reflected and detected by the imaging unit, using a detection unit to determine the optimal illumination unit for each imaging scenario.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple illumination units are used to image a target area, then imaging coverage and flexibility are improved, but determining the optimal illumination unit becomes complex and time-consuming
Solution Approach 1:
The patent replaces manual or mechanical selection methods with an automated determination system that calculates optimal illumination units based on positional relationships. The control unit automatically identifies which illumination unit should be activated by computing geometric relationships between the target area, imaging unit, and multiple illumination units, substituting complex mechanical decision-making with algorithmic processing.
Solution Approach 2:
The system enables self-service by allowing the illumination unit determination to be automatically performed based on real-time positional data. The control unit autonomously determines the optimal illumination unit without requiring external intervention or complex manual configuration, making the system self-regulating and adaptive to changing conditions.
2Reliability
If the positional relationship between illumination unit and imaging unit is fixed, then imaging consistency is improved, but the system cannot adapt to moving targets or changing positions
Solution Approach 1:
The patent implements dynamics by making the illumination unit selection adaptive to changing positional relationships. Instead of a fixed configuration, the system continuously determines the optimal illumination unit based on real-time positions of the target area and imaging unit, allowing the system to dynamically adjust to moving targets or repositioned components while maintaining imaging quality.
Solution Approach 2:
The system employs feedback mechanisms where the control unit receives positional information about the target area and imaging unit, processes this information to determine the optimal illumination unit, and adjusts the illumination accordingly. This closed-loop approach ensures imaging consistency is maintained while adapting to positional changes.
3Reliability
If all illumination units operate simultaneously, then imaging completeness is improved, but power consumption increases
Solution Approach 1:
The patent applies the extraction principle by selectively activating only the necessary illumination unit(s) rather than operating all illumination units simultaneously. The control unit determines which specific illumination unit is optimal for the current imaging scenario and activates only that unit, extracting the essential function while eliminating unnecessary energy consumption from redundant illumination sources.
Solution Approach 2:
The system uses partial action by activating only the minimum necessary illumination resources to achieve complete imaging. Instead of using all available illumination units, the control unit identifies and activates only the optimal subset required for the task, reducing power consumption while maintaining imaging completeness through precise, targeted illumination.
