Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a power feeder is used to wirelessly charge a battery, then the battery can be charged without direct contact, but the power feeder must be placed close to the device, limiting flexibility
Solution Approach 1:
The semiconductor device contains an oscillator circuit that can autonomously generate and transmit electromagnetic waves to charge other devices' batteries. This self-service capability eliminates the need for an external power feeder, allowing any device to act as a charging source for others, thereby achieving both wireless charging convenience and placement flexibility.
Solution Approach 2:
The semiconductor device is designed with dual functionality: it can both receive electromagnetic waves for charging its own battery and transmit electromagnetic waves to charge other devices' batteries. This multi-functionality allows the device to serve as both a charger and a chargee, resolving the contradiction by making the system self-sufficient and highly adaptable to various placement scenarios.
2Productivity
If multiple semiconductor devices with batteries are charged simultaneously using a power feeder, then all devices can be charged wirelessly, but each device still requires the power feeder to be placed close to it
Solution Approach 1:
Each semiconductor device is equipped with an oscillator circuit that enables it to independently charge other devices wirelessly. This self-service capability allows devices to charge each other without requiring an external power feeder, thereby maintaining high charging efficiency while significantly reducing system arrangement complexity.
Solution Approach 2:
The patent combines the charging function and communication function into a single semiconductor device with an oscillator circuit. This merging allows the device to perform both wireless charging and data communication using the same electromagnetic wave transmission capability, improving productivity while simplifying the overall system architecture.
3Adaptability or versatility
If a semiconductor device has both wireless charging capability and communication capability, then it can perform multiple functions, but the device structure becomes more complex
Solution Approach 1:
The oscillator circuit is designed to serve dual purposes: generating electromagnetic waves for wireless charging and enabling communication with other devices. By making the oscillator circuit universal, the patent achieves functional versatility (both charging and communication) without significantly increasing device complexity, as the same hardware component performs multiple functions.
Solution Approach 2:
The patent merges the wireless charging function and the communication function into a single integrated system. The antenna circuit and oscillator circuit used for charging are also utilized for communication, eliminating the need for separate dedicated hardware for each function and thereby maintaining device structure simplicity while achieving high adaptability.
