Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an extended base unit with uniform energy transmission is used, then freedom of movement is provided, but the system is not suitable for high energy applications
Solution Approach 1:
The base unit is divided into multiple discrete inductive power outlets positioned at specific locations. Each outlet contains a primary inductor that can be independently activated. This segmentation allows the system to provide focused high-power transmission to specific devices while maintaining the ability to accommodate multiple devices at different positions, thus resolving the contradiction between extended coverage and high power capability.
2Reliability
If a male connector is inserted into a female connector for alignment, then precise inductive coupling is achieved, but the freedom of movement is unduly restricted
Solution Approach 1:
The patent replaces the mechanical connector system (male/female plugs requiring physical insertion) with an inductive coupling system using primary and secondary inductors. The inductors generate magnetic fields that couple through air or non-conductive barriers, eliminating the need for precise mechanical alignment and physical connection. This allows devices to be positioned freely while maintaining reliable inductive power transmission.
3Power
If trailing leads are used to connect devices, then power can be transmitted, but the leads may become snagged or tangled
Solution Approach 1:
The patent eliminates trailing electrical leads by using inductive power transmission through magnetic coupling between primary inductors in the base unit and secondary inductors in the devices. This wireless power transmission method removes the mechanical constraint of trailing cables, allowing complete freedom of movement without snagging or tangling while maintaining continuous power supply.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables high-power inductive power transmission to electrical devices positioned anywhere over an extended region without restricting movement, while ensuring efficient power distribution and minimizing maintenance through a centralized control system.
Implementation Method 1
A power supply is wired to a primary coil and an oscillating electric potential is applied across the primary coil which induces an oscillating magnetic field. The oscillating magnetic field may induce an oscillating electrical current in a secondary coil, placed close to the primary coil.
Implementation Method 2
The oscillating magnetic field may induce an oscillating electrical current in a secondary coil, placed close to the primary coil. In this way, electrical energy may be transmitted from the primary coil to the secondary coil by electromagnetic induction without the two coils being conductively connected.
