Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electronic device relies on battery power for operation, then the device can be portably operated, but the remaining battery capacity decreases, causing communication interruption
Solution Approach 1:
The patent introduces a power supply apparatus as an intermediary device that wirelessly supplies power to the electronic device during communication operations. This mediator enables the device to maintain both portability and communication reliability by providing external power support when needed, without requiring the device to be constantly connected to a power source.
2Productivity
If the electronic device transmits video data using Bluetooth communication, then data transmission can be performed, but the transmission may be interrupted due to low battery capacity
Solution Approach 1:
The patent implements preliminary action by having the control unit check the remaining battery capacity before initiating Bluetooth communication for video data transmission. If the battery capacity is insufficient, the system proactively switches to using power from the power supply apparatus, preventing transmission interruptions before they occur.
3Adaptability or versatility
If the electronic device uses battery power for Bluetooth communication, then wireless communication can be performed, but authentication may fail when battery capacity is low
Solution Approach 1:
The patent applies dynamics by making the power source flexible and switchable. The system dynamically selects between battery power and power supply apparatus based on real-time battery capacity conditions. This dynamic adaptation ensures that authentication and wireless communication can proceed reliably regardless of the device's battery state.
4Duration of action of stationary object
If the electronic device operates with low battery capacity, then the device can continue to function, but user burden increases due to repeated data transmission
Solution Approach 1:
The patent ensures continuity of useful action by maintaining uninterrupted video data transmission between the electronic device and personal computer. By switching to external power when battery capacity is low, the system prevents transmission interruptions that would otherwise require user intervention for retransmission, thereby eliminating time loss while extending operational duration.
