Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems for target authentication face challenges in improving the reliability and efficiency of imaging and authentication processes, particularly in maintaining the ideal positional relation between imaging units and illumination sources during movement.
Innovation Solution
The information processing apparatus includes a first and second imaging unit, a lighting unit, a reflection unit, and a drive unit that positions these components to maintain the ideal positional relation, even when the imaging units and reflection mirror are rotated, thereby reducing the likelihood of wire disconnection and heat transfer issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the imaging units and reflection mirror are rotated to adjust imaging angles, then the imaging coverage and flexibility are improved, but the wire connection reliability deteriorates due to increased disconnection risk
Solution Approach 1:
The lighting unit is extracted from the rotating assembly and positioned separately. The reflection unit is also separated from the imaging units. This extraction eliminates the wire disconnection problem caused by rotation while preserving the functional relationship between components through optical paths.
Solution Approach 2:
The system is segmented into distinct functional modules: imaging units, lighting unit, and reflection unit, each independently positioned. The drive unit controls the reflection unit's positioning separately from the imaging units, allowing independent optimization of each component's position and function.
2Volume of moving object
If the lighting unit is positioned close to the imaging units for compact design, then the device size is reduced, but heat transfer to imaging units increases causing operational issues
Solution Approach 1:
The lighting unit is extracted from the compact assembly with imaging units and positioned separately. This separation reduces heat transfer to imaging units while the reflection unit redirects light to maintain imaging functionality, effectively solving the heat problem without sacrificing device compactness.
Solution Approach 2:
The reflection unit acts as an intermediary between the lighting unit and imaging units. It redirects light from the separately positioned lighting unit to the imaging units, maintaining the optical function while allowing physical separation that prevents heat transfer.
3Device complexity
If the drive unit is integrated with the lighting unit for synchronized control, then the control complexity is reduced, but the positional relation between imaging units and illumination sources cannot be maintained during movement
Solution Approach 1:
The drive unit is extracted from the lighting unit and positioned separately to control the reflection unit independently. This allows the imaging units and illumination sources to maintain their ideal positional relations during movement, as each component can be positioned and controlled independently without compromising the other.
