Innovation Solution
An optical sensor with a movable radiation part and imaging part, controlled by driving mechanisms, allows for adjustment of the measurement range and focus position, enabling a single sensor to accurately measure objects of various sizes and geometries by moving the radiation part in the radiation direction and the imaging part in the reflection and orthogonal directions, while maintaining measurement accuracy through rotation to satisfy the Scheimpflug principle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple optical sensors with different measurement ranges are used to measure objects of varying sizes and geometries, then measurement accuracy is improved, but device complexity increases
Solution Approach 1:
The patent applies the dynamics principle by making the radiation part and imaging part movable relative to each other. The radiation part can be moved in the radiation direction of laser light, and the imaging part can be moved in the reflection direction and orthogonal direction. This dynamic adjustment capability allows a single optical sensor to adapt to objects of various sizes and geometries, eliminating the need for multiple fixed-range sensors while maintaining measurement accuracy.
Solution Approach 2:
The patent implements universality by designing a single optical sensor that can measure objects across a wide range of sizes and geometries. Through the movable radiation part and imaging part, the sensor can adjust its measurement range and focus position, making it a universal measurement tool that replaces multiple specialized sensors with different measurement ranges.
2Device complexity
If a single optical sensor is used to measure objects of various sizes and geometries, then device complexity is reduced, but measurement precision deteriorates
Solution Approach 1:
The movable radiation part and imaging part enable dynamic adjustment of the measurement range and focus position. This allows the single optical sensor to optimize its configuration for each specific measurement task, maintaining high measurement precision across different object sizes and geometries despite using only one sensor.
Solution Approach 2:
The patent changes the physical parameters of the optical sensor system by moving the radiation part in the radiation direction and the imaging part in the reflection and orthogonal directions. These parameter changes (position, distance, orientation) allow the sensor to adapt to different measurement scenarios, maintaining measurement accuracy across various object types.
3Adaptability or versatility
If the radiation part and imaging part are made movable to adjust measurement range, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent introduces controlled dynamics by making specific parts (radiation part and imaging part) movable while keeping the overall sensor structure integrated. This selective movability provides the necessary adaptability for different measurement scenarios without requiring complete system reconfiguration, balancing versatility with manageable complexity.
Solution Approach 2:
The optical sensor is segmented into movable components (radiation part and imaging part) that can be independently adjusted. This segmentation allows each component to be optimized for its specific function while enabling flexible reconfiguration of the entire system, improving adaptability without proportionally increasing overall device complexity.
