Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electrical plugs and cords are used to provide power to appliances, then reliable power delivery is achieved, but convenience deteriorates due to clutter, frequent unplugging, and restricted appliance placement
Solution Approach 1:
The patent replaces the mechanical plug-and-cord connection system with a wireless electromagnetic field-based power transmission system. The primary coil generates an oscillating magnetic field that induces current in the secondary coil, eliminating the need for physical electrical connections and thereby removing clutter while maintaining reliable power delivery.
Solution Approach 2:
The patent introduces an electromagnetic field as an intermediary medium to transfer power between the power source and the appliance. The primary coil creates a magnetic field that acts as a mediator, allowing energy transfer without direct physical contact between the power source and the appliance, thus improving convenience.
2Adaptability or versatility
If multiple appliances are connected to power outlets, then power needs are met, but reliability deteriorates due to overload risks and the need to unplug devices
Solution Approach 1:
The patent divides the power delivery system into independent wireless power zones, each with its own primary coil. This segmentation allows multiple appliances to be powered simultaneously in different locations without sharing a common electrical circuit, thereby eliminating overload risks while maintaining the ability to power multiple devices.
3Device complexity
If wireless power transmission is implemented without feedback control, then system simplicity is maintained, but power delivery precision deteriorates for appliances with variable power demands
Solution Approach 1:
The patent implements a feedback control system where sensors detect the power needs of the appliance and transmit this information wirelessly to the controller. The controller adjusts the primary coil's oscillation parameters based on this feedback, enabling precise power delivery that adapts to the appliance's variable demands while maintaining reasonable system complexity.
