Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If electromagnetic waves are transmitted through a sheet-shaped communication medium using surface communication, then wireless power transmission between devices is achieved, but electromagnetic waves leak from gaps between devices and the sheet, degrading communication performance
Solution Approach 1:
An electromagnetic wave suppression unit is introduced as an intermediary component between the power feeding/reception devices and the sheet-shaped communication medium. This suppression unit, constructed with conductor unit structures arranged in a matrix pattern, acts as a mediator that selectively blocks leaked electromagnetic waves from propagating outward while allowing the sheet to function as a communication medium, thereby preventing energy loss without interfering with the primary communication function
Solution Approach 2:
The electromagnetic wave suppression unit is positioned only at specific locations where gaps exist between devices and the sheet, rather than covering the entire sheet. The conductor unit structures are arranged in a matrix pattern at these critical gap regions, providing localized suppression of electromagnetic wave leakage precisely where needed, thus maintaining communication performance while reducing overall energy loss
2Object-generated harmful factors
If electromagnetic waves are transmitted through gaps between devices and sheet, then power transmission occurs, but leaked waves affect the surrounding radio wave environment
Solution Approach 1:
The electromagnetic wave suppression unit converts the harmful leaked electromagnetic waves into beneficial reflected waves by using conductor unit structures that reflect the leaked energy back toward the sheet-shaped communication medium. This transformation turns the harmful radiated power that would interfere with the radio wave environment into useful energy that remains within the communication system, simultaneously reducing interference and preventing energy loss
