Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple blowers are connected using wiring to supply power, then power can be supplied to multiple blowers, but the internal structure becomes complicated and manufacturing cost increases
Solution Approach 1:
The patent replaces the mechanical wiring system with a magnetic field-based wireless power transmission system. The transmitter unit generates a magnetic field that induces current in the receiver unit, eliminating the need for physical wire connections between blowers while maintaining reliable power supply.
Solution Approach 2:
The controller unit serves multiple functions: it controls both the transmitter unit for wireless power transmission and the blower motor. This multi-functionality reduces the need for separate control circuits and wiring, simplifying the overall internal structure while maintaining operational reliability.
2Reliability
If multiple blowers are connected using wiring, then power can be supplied to multiple blowers, but coupling and separation becomes complicated and may cause malfunctions
Solution Approach 1:
The patent eliminates the mechanical connection requirement by using wireless magnetic field-based power transmission. The transmitter and receiver units communicate and transfer power through magnetic fields, allowing blowers to be coupled and separated without worrying about wire disconnection or incorrect connections.
Solution Approach 2:
The system automatically establishes magnetic field coupling between transmitter and receiver units when brought into proximity. The controller detects the presence of the receiver unit and automatically initiates power transmission, eliminating the need for manual wiring connections during coupling.
