Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If T-pieces (junction boxes) are used for energy branching, then electrical connection is achieved, but device complexity and installation cost increase significantly
Solution Approach 1:
The patent replaces mechanical plug connectors and T-pieces with inductive coupling between primary and secondary windings. Energy is transferred wirelessly through magnetic fields, eliminating the need for physical electrical contacts and complex junction boxes, thus reducing device complexity while maintaining reliable electrical connection.
Solution Approach 2:
The patent introduces magnetic fields as an intermediary medium for energy transfer. The primary winding generates a magnetic field that couples with the secondary winding to transfer energy, serving as a non-contact intermediary that eliminates the need for direct electrical connections and complex wiring infrastructure.
2Reliability
If T-pieces are used in wet or aseptic areas, then energy supply is achieved, but installation difficulty and cost increase
Solution Approach 1:
By replacing mechanical plug connectors and T-pieces with inductive coupling, the patent eliminates exposed electrical contacts that would require protective enclosures in wet or aseptic areas. The contactless energy transfer allows simple, sealed housings without complex wiring access points, making installation easier and more suitable for harsh environments.
3Ease of operation
If contactless supply methods are implemented, then installation simplicity improves, but cost-effectiveness and efficiency deteriorate
Solution Approach 1:
The patent optimizes inductive coupling efficiency by adjusting parameters such as winding geometry, core material, and operating frequency. By tuning these parameters, the system achieves high efficiency wireless power transfer that is cost-effective and suitable for industrial applications, overcoming the traditional disadvantage of contactless supply methods.
4Productivity
If detachable insertion part is used, then connection speed improves, but manufacturing complexity increases
Solution Approach 1:
The patent divides the system into modular components: a detachable insertion part containing the secondary winding and a stationary part with the primary winding. This segmentation enables quick connection and disconnection by simply plugging in the insertion part, while each module can be manufactured independently using standard techniques, balancing manufacturing simplicity with connection speed.
