Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an external wire is used to hang the optical detecting device on the display device, then the device can be connected to detect color information, but it cannot conveniently detect several different positions of the frame such as the middle position
Solution Approach 1:
The patent implements a telescopic arm mechanism that allows the optical detecting device to dynamically extend and retract. The arm can be extended to reach different positions on the display frame (including middle positions) and retracted when not needed, providing both ease of operation for position adjustment and adaptability to detect multiple locations without requiring multiple fixed installations
Solution Approach 2:
The detecting device is segmented into a fixed receiving box portion and a movable telescopic arm portion. This segmentation allows the arm to be independently extended or retracted to access different sensing positions while the receiving box remains stationary, resolving the contradiction between operational convenience and positional versatility
2Adaptability or versatility
If the telescopic arm slides relative to the receiving box to reach different sensing positions, then multiple positions can be detected, but electrical connectivity may be lost during movement
Solution Approach 1:
The patent introduces conductive portions as intermediary elements between the telescopic arm and the receiving box. These conductive portions maintain continuous electrical connection during the sliding movement of the arm, allowing the arm to extend and retract to different sensing positions while preserving reliable electrical connectivity for data and power transmission
Solution Approach 2:
The patent replaces traditional mechanical sliding contacts with conductive portions that maintain electrical connection through the sliding mechanism. This substitution ensures that electrical connectivity is maintained during movement without the wear and contact loss issues of conventional mechanical connectors, simultaneously achieving positional versatility and connection reliability
3Measurement precision
If the optical sensor is exposed to detect light from different positions, then color information can be detected, but light leakage may reduce detection accuracy
Solution Approach 1:
The patent extracts and isolates the optical sensor within a dedicated sensing area on the telescopic arm. By defining a specific light-receiving region and separating it from other components, the design enables accurate color detection from different positions while minimizing interference from unwanted light sources through proper optical path design
Solution Approach 2:
The patent addresses light leakage by using the telescopic arm's structure and positioning mechanism to control the direction and source of light reaching the sensor. The arm's extension to specific positions allows the sensor to receive light only from intended areas of the display, converting the potential harm of light leakage into beneficial directional light collection that improves detection precision
