Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the underwater moving device is held exactly at a specific charging position for optimal charging efficiency, then charging efficiency is improved, but the system becomes sensitive to position shifts and requires precise positioning
Solution Approach 1:
The patent employs magnetic components that dynamically adjust and maintain the alignment between transmitter and receiver. The magnetic attraction force automatically compensates for position shifts, allowing the device to remain charged efficiently without requiring precise manual positioning. This dynamic magnetic coupling replaces static precise positioning requirements.
Solution Approach 2:
The magnetic field acts as an intermediary force between the charging device and the underwater moving device. This magnetic intermediary enables automatic alignment and maintains optimal charging conditions without requiring direct mechanical positioning or complex control systems, thus improving ease of operation while maintaining charging efficiency.
2Adaptability or versatility
If the underwater moving device shifts slightly from the specific charging position, then positioning tolerance is improved, but charging efficiency deteriorates
Solution Approach 1:
The magnetic coupling system dynamically adapts to position shifts by maintaining magnetic attraction between the components. This dynamic system allows the underwater moving device to shift within certain tolerances while the magnetic force continuously adjusts to maintain optimal charging alignment, thus preserving charging efficiency despite position variations.
Solution Approach 2:
The patent utilizes magnetic field parameters to maintain charging efficiency across different positions. By changing the magnetic field distribution and strength, the system compensates for position shifts and maintains effective wireless power transfer even when the device is not perfectly positioned, thereby improving position tolerance without sacrificing charging efficiency.
