Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the terminal uses OTG cable for data communication with external devices, then data communication function is enabled, but when battery power is low, the cable must be disconnected for recharging which interrupts communication
Solution Approach 1:
The patent merges the recharging function and data communication function into a single operational mode by introducing a dual-role external device that can simultaneously provide power supply and data communication capabilities through the same OTG connection, eliminating the need to disconnect cables for charging
Solution Approach 2:
The external device is designed with multi-functionality, serving both as a power source and a data communication interface. This universal device can adapt its role based on the terminal's battery status, providing power when needed while maintaining communication capabilities throughout
2Use of energy by moving object
If the terminal disconnects OTG cable for recharging, then battery can be recharged, but data communication with connected devices is interrupted
Solution Approach 1:
The patent ensures continuous useful action by maintaining both power supply and data communication functions simultaneously through the external device. The system transitions smoothly between charging modes without interrupting the communication workflow, ensuring uninterrupted operation
3Adaptability or versatility
If the terminal supports both recharging and data communication functions, then operational flexibility is improved, but system complexity increases
Solution Approach 1:
The system implements self-service through automatic mode detection and switching. The terminal automatically detects the external device's capabilities and selects the appropriate operational mode (recharging, data communication, or both simultaneously) without requiring user intervention or complex manual configuration
