Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If coupling electrodes are positioned to be opposed to each other, then transmission characteristics are improved, but device flexibility and orientation are limited
Solution Approach 1:
A dielectric material is introduced as an intermediary between the coupling electrode and the housing. This dielectric extends the electric field distribution, allowing the electrode to couple effectively with opposing electrodes even when not directly opposed, thus maintaining transmission characteristics while enabling flexible device orientation
Solution Approach 2:
The dielectric material extends the coupling capability from a single-point opposition to a multi-dimensional field distribution. By having multiple faces of the dielectric contact multiple faces of the housing, the system achieves coupling in multiple spatial dimensions, enabling flexible orientation while maintaining reliable transmission
2Adaptability or versatility
If coupling electrodes are positioned at increased distances, then device adaptability is improved, but transmission characteristics deteriorate
Solution Approach 1:
The dielectric material acts as a field-extending intermediary that bridges the gap between coupling electrodes at increased distances. It distributes the electric field across multiple faces, maintaining effective coupling even when electrodes are not in direct opposition or are positioned at greater separations
Solution Approach 2:
The dielectric material provides universal coupling capability across multiple orientations and positions. By contacting multiple faces of the housing, it enables the same coupling electrode to effectively interact with opposing electrodes in various spatial configurations, achieving distance and orientation independence
