Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional electrical supply systems are installed in floor and wall areas, then electrical energy can be supplied to devices, but the aesthetic appearance is reduced and tripping hazards are created
Solution Approach 1:
The patent replaces conventional mechanical electrical outlets and extension cables with a wireless inductive energy transmission system. The transmitting device embedded in the floor or wall generates a magnetic field that inductively couples with the receiving device in the supply unit, eliminating the need for visible cables and physical socket connections, thus resolving the aesthetic and safety issues while maintaining energy supply functionality
Solution Approach 2:
The patent introduces a magnetic field as an intermediary medium between the transmitting device and the receiving device. This magnetic field enables wireless energy transmission through the floor or wall structure without requiring physical electrical connections, thereby eliminating visible cables and improving both aesthetics and safety
2Ease of manufacture
If extension cables are laid on the floor to connect devices to electrical access points, then electrical energy can be transmitted, but the aesthetic appearance is reduced and disturbances to people and equipment occur
Solution Approach 1:
The patent eliminates mechanical extension cables by implementing wireless inductive energy transmission. The transmitting device embedded in the building structure creates a magnetic field that directly couples with the receiving device, removing the need for floor-laid cables and thereby improving aesthetics and room usability without compromising energy transmission
3Adaptability or versatility
If floor boxes and wall outlets are installed for electrical supply, then electrical access is provided, but the technological complexity of installation increases
Solution Approach 1:
The patent creates a universal energy supply system where a single transmitting device embedded in the floor or wall can serve multiple receiving devices simultaneously through magnetic field coverage. This eliminates the need for installing separate floor boxes and wall outlets at each access point, reducing installation complexity while maintaining versatile electrical access throughout the space
