Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless charging is continuously performed on stored electronic devices, then battery power levels are maintained, but unnecessary charging cycles increase power consumption and operational burden
Solution Approach 1:
The decision unit continuously monitors the battery power level of the electronic device and uses this feedback information to intelligently control the charging unit. When the power level exceeds the threshold, the system automatically stops wireless charging, preventing unnecessary energy consumption while ensuring the battery remains adequately charged.
Solution Approach 2:
The electronic device autonomously determines whether charging is needed by comparing its current power level against a predetermined threshold. The device self-regulates the charging process without requiring external intervention, enabling it to service itself by stopping charging when sufficient power is available.
2Reliability
If cable charging is used for packed devices, then charging reliability is ensured, but operational complexity increases
Solution Approach 1:
The electronic device automatically initiates and manages the wireless charging process through its decision unit and charging unit. The device itself determines when charging is needed and executes the charging operation without requiring user intervention to connect cables or configure settings, thereby simplifying operation while maintaining reliability.
Solution Approach 2:
The patent replaces the mechanical cable connection system with a wireless power transmission system. By using electromagnetic fields for power transfer instead of physical cable connections, the system eliminates the operational burden of plugging and unplugging cables while maintaining charging reliability through automated control.
3Reliability
If wireless charging is performed on all devices regardless of state, then power supply is ensured, but power waste increases due to high-power charging in packed states
Solution Approach 1:
The decision unit receives real-time feedback on the battery power level of each electronic device and uses this information to control the wireless charging transmission. When the detected power level exceeds the predetermined threshold, the system reduces or stops power transmission to that specific device, preventing energy waste while ensuring devices below the threshold receive adequate power supply.
Solution Approach 2:
Instead of providing full-power charging to all devices uniformly, the system applies partial charging only to devices that need it (those below the power threshold). This selective approach avoids excessive power delivery to devices with sufficient charge, reducing overall energy waste while maintaining adequate power supply for devices that require it.
