Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If media are photographed by moving an irradiation unit up and down, then the structure is simple, but detection accuracy is insufficient
Solution Approach 1:
The patent transitions from moving the irradiation unit in the vertical dimension (up and down) to rotating the irradiation unit around the media in the horizontal dimension. This dimensional change allows the light to consistently illuminate the side surfaces of floated media from optimal angles, significantly improving detection accuracy while maintaining structural simplicity through rotational movement rather than complex vertical positioning mechanisms.
Solution Approach 2:
The patent changes the illumination parameter by rotating the irradiation unit to different angular positions around the media. Instead of moving vertically to change illumination perspective, the system rotates the light source around the media, maintaining consistent vertical illumination distance while varying the horizontal angle to optimally capture side surfaces of floated media, thereby improving detection accuracy.
2Measurement precision
If light is irradiated at fixed angles, then the device is simple to operate, but detection precision is insufficient for floated media
Solution Approach 1:
The patent introduces dynamic adjustment capability to the irradiation unit, allowing it to rotate to multiple angular positions around the media. This dynamic rotation enables the system to adapt to different media positions and floating states, optimizing light illumination angles for accurate side surface detection while maintaining automated control that preserves operational simplicity.
Solution Approach 2:
The system incorporates feedback mechanisms where the photographing unit captures images of floated media, and based on detection results, the irradiation unit adjusts its rotation angle to optimize illumination. This feedback loop ensures high detection precision by continuously adapting light angles to actual media positions while the automation maintains ease of operation through centralized control.
