Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If numerous connections are used to contact winding wires in resolvers, then electrical connectivity is achieved, but the number of vulnerable connections increases reducing robustness
Solution Approach 1:
The patent combines multiple functions into the connection pins: they provide both mechanical support and electrical contact. The pins serve as both structural elements to hold the winding wires and as electrical conductors to transmit signals, thereby reducing the total number of separate connections needed while improving robustness.
Solution Approach 2:
The connection pins are designed as multi-functional elements that simultaneously perform mechanical support, electrical conduction, and positioning functions. This universal design reduces the number of separate components needed and minimizes vulnerable connection points in the resolver structure.
2Ease of manufacture
If traditional contacting methods are used for winding wires, then electrical contact is established, but manufacturing effort and complexity increase
Solution Approach 1:
The patent divides the connection structure into discrete, standardized connection pins that can be individually manufactured and assembled. This segmentation allows for simplified manufacturing processes where each pin is a separate, easily fabricated component rather than part of a complex integrated structure.
Solution Approach 2:
The connection pins act as intermediary elements between the winding wires and the external circuitry. These standardized intermediate components simplify the manufacturing process by providing a uniform interface that is easy to manufacture and assemble, reducing overall manufacturing effort.
