Solution Overview

Problem

The existing stator units face inefficiencies in manufacturing due to wire tangling and misconnection issues when pulling out and connecting the ends of coils.

Innovation Solution

A stator unit design incorporating a routing member with groove portions to guide and route the wires, preventing tangling and misconnection by using guide slits and collection grooves to organize and connect the wires efficiently.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If wires are pulled out from coils for connection, then the coils can be connected to form the stator unit, but the wires may get tangled and misconnected which lowers manufacturing efficiency

Engineering Contradiction:

Improveease of wire connectionVSAvoidmanufacturing efficiency

Core Design Contradiction:

Ease of manufactureVSProductivity

Solution Approach 1:

The routing member is prepared in advance with pre-formed groove portions and guide slits that define the exact path for wire routing. This preliminary preparation of the routing structure eliminates the need for complex manual wire management during assembly, allowing workers to simply follow the pre-defined grooves and guide slits to connect wires correctly and efficiently.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The routing member acts as an intermediary component between the coils and the connection points. It provides a structured interface with groove portions and guide slits that mediate the wire routing process, preventing direct contact and tangling between multiple wires while guiding them to their correct destinations for connection.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If wires are manually routed and connected without guidance, then flexibility in connection methods is maintained, but wire tangling and misconnection occur reducing manufacturing precision

Engineering Contradiction:

Improveflexibility in connection methodVSAvoidwire connection accuracy

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The routing member is segmented into multiple functional zones including groove portions for individual wire routing, guide slits for directional guidance, and collection portions for organizing wire ends. Each segment performs a specific function in the wire routing process, maintaining precision through structured segmentation while allowing adaptability in the overall connection approach.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The routing member serves as an intermediary structure that imposes order on the wire routing process. The groove portions and guide slits act as mediating elements that guide wires along precise paths without restricting the overall flexibility of connection methods, as wires can still be routed to different destinations based on design requirements.

Inventive Principle:

Principle #24Intermediary (Mediator)
