Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If wireless power transmission and wireless communication arrangements are integrated in close proximity, then device complexity is reduced, but electromagnetic interference between power and communication signals increases
Solution Approach 1:
A magnetic shield is introduced as an intermediary component between the wireless power transmission arrangement and the wireless communication arrangement. This magnetic shield acts as a mediator that blocks or attenuates the electromagnetic field from the power transmission arrangement, preventing it from interfering with the communication arrangement while allowing both systems to operate in close proximity.
Solution Approach 2:
The harmful electromagnetic field from the power transmission arrangement is extracted or isolated from the communication arrangement by using the magnetic shield to remove or block the interfering field, allowing the two arrangements to coexist without mutual interference.
2Object-affected harmful factors
If the distance between communication units is increased to reduce interference, then electromagnetic interference is minimized, but communication reliability may be affected
Solution Approach 1:
The magnetic shield serves as a protective intermediary that allows communication units to maintain optimal spacing for reliability while blocking external electromagnetic interference from the power transmission arrangement, thus preserving both communication reliability and minimizing interference simultaneously.
