Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If operators rely on visual inspection of connector markings (white dot and key position) to determine patch cord polarity, then no additional detection equipment is needed, but the polarity determination is difficult and time-consuming
Solution Approach 1:
The patent replaces the manual visual inspection method with an automated optical detection system. The polarity detector uses optical signals to automatically identify connector types and determine polarity, substituting the mechanical/visual process with an optical-electronic system that provides rapid and accurate results without operator strain.
Solution Approach 2:
The polarity detector enables the patch cord system to self-identify its polarity characteristics. By automatically detecting connector markings and determining polarity without external assistance, the system performs its own identification function, eliminating the need for operators to manually interpret visual cues.
2Loss of information
If prior art patch cord managing devices are used to display polarity information, then some polarity data may be provided, but the polarity remains difficult to discern and operation efficiency deteriorates
Solution Approach 1:
The polarity detector provides immediate feedback by automatically detecting connector markings and displaying polarity determination results. The system receives optical signals from connector features, processes them through analysis units, and provides real-time polarity information feedback, enabling operators to quickly confirm correct patch cord selection without manual interpretation.
Solution Approach 2:
The detector utilizes optical reflection characteristics and color properties of connector markings (such as the white dot) to determine polarity. By analyzing how different connector features reflect or absorb light, the system translates visual markings into actionable polarity information that is easily discerned by operators.
