Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mobile terminals are connected through a cable to transmit power and data, then power transmission and data exchange functionality is improved, but device complexity and control management become worsened
Solution Approach 1:
The controller automatically determines whether to transmit or receive power based on the connection state without requiring manual user input. The system self-manages the power transmission decision-making process by detecting connection status and autonomously selecting the appropriate power mode, thereby resolving the control complexity issue while maintaining versatile power exchange functionality
Solution Approach 2:
The controller continuously monitors the connection state between mobile terminals and uses this feedback information to dynamically adjust power transmission decisions. By implementing a feedback mechanism that tracks connection status, the system can adaptively manage power flow direction and intensity, solving the contradiction between versatile power exchange and simplified control management
2Ease of operation
If a controller automatically determines power transmission based on connection state, then ease of operation is improved, but loss of information about user intent may occur
Solution Approach 1:
The system performs preliminary detection of connection state before initiating power transmission. By checking the connection status in advance and preparing the power transmission mechanism accordingly, the system ensures that automatic control actions are taken only when appropriate connection conditions are met, thereby preserving user intent while maintaining ease of operation
Solution Approach 2:
The controller implements preliminary verification of connection state to prevent inappropriate power transmission. By checking connection conditions before acting and having predetermined rules for when power transmission should occur, the system prevents erroneous automatic actions that would contradict user intent, thus balancing convenience with information preservation
