Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional wiring device structure is used, then the wiring process can be completed, but the structure becomes complicated and manufacturing cost increases
Solution Approach 1:
The wiring device is divided into multiple independent guiding portions, each with its own accommodating hole. Each guiding portion handles a specific phase wire separately, preventing entanglement while maintaining a simple overall structure that can be manufactured cost-effectively.
Solution Approach 2:
The wiring device acts as an intermediary component between the coil windings and the external circuit. It provides a structured pathway through the accommodating holes and guiding portions, organizing the wires without requiring complex internal wiring structures.
2Ease of operation
If manual wiring is used, then flexibility is maintained, but mistakes and entanglement increase
Solution Approach 1:
By providing separate accommodating holes and guiding portions for each phase wire (U, V, W phases), the device segments the wiring paths. This prevents manual wiring mistakes and entanglement while maintaining ease of operation, as each wire has its designated path to follow.
Solution Approach 2:
The wiring device is prepared in advance with pre-positioned guiding portions and accommodating holes. This preliminary arrangement of wire paths eliminates the need for complex manual routing during assembly, reducing mistakes while maintaining operational simplicity.
3Adaptability or versatility
If the wiring device is designed for multiple phases, then versatility increases, but structure becomes overcomplicated
Solution Approach 1:
The wiring device is designed with a universal structure that can accommodate three-phase, four-phase, five-phase, six-phase, or multiple-phase motors. Each phase has its own guiding portion and accommodating hole, but they all follow the same design pattern, allowing the device to handle different phase configurations without becoming overcomplicated.
Solution Approach 2:
The wiring device accommodates different phase configurations by changing the number and arrangement of guiding portions and accommodating holes. The basic structure remains the same, but parameters such as the number of phases and their spatial arrangement can be adjusted to suit different motor types.

AI summary
A wiring device includes a plurality of trenches and a plurality of channel sets. The trenches at least include a first trench, a second trench and a third trench, bottoms of which are respectively located at different height positions. Each of the channel sets at least includes a first channel, a second channel and a third channel. The first channels penetrate the wiring device from an outer sidewall thereof to the first trenches, respectively, the second channels penetrate the wiring device from the outer sidewall thereof to the second trenches, respectively, and the third channels penetrate the wiring device from the outer sidewall thereof to the third trenches, respectively. The wiring device has the advantages of a simple structure and a low cost for molding and manufacturing, and is suitable to perform winding by a manual or automatic machine and thus can prevent first output wires of the coil windings with in phase or out of phase from entangling or knotting with each other.
