Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If voltage correction is performed based on cable length to maintain voltage within allowable range, then voltage stability is improved, but system complexity increases due to additional detection and correction mechanisms
Solution Approach 1:
The system implements feedback by detecting the actual voltage at the power reception apparatus and comparing it with the target voltage. Based on this feedback, the power supply apparatus adjusts its output voltage to compensate for cable-induced voltage drops, thereby maintaining voltage stability without requiring complex open-loop calculations
Solution Approach 2:
The power supply apparatus automatically adjusts its output based on detected voltage conditions without requiring manual intervention or complex external control systems. The system self-regulates by detecting voltage drops and autonomously correcting the output voltage to maintain stability
2Use of energy by moving object
If minimum necessary electric power is supplied depending on video camera action, then power efficiency is improved, but control complexity increases
Solution Approach 1:
The system dynamically adjusts the supplied electric power based on the actual operational state of the video camera. By detecting the camera's action state and adapting the power supply accordingly, the system achieves power efficiency without requiring overly complex control mechanisms, as the adjustment is driven by real-time operational feedback
3Ease of operation
If power supply status and margin information are displayed in real-time, then operability is improved, but information processing requirements increase
Solution Approach 1:
The system extracts and displays only the most critical power supply information such as voltage margins, current status, and threshold warnings. By selectively presenting essential data rather than processing and displaying all possible parameters, the system improves operability while minimizing unnecessary information processing load
