Solution Overview

Problem

Existing automatic wire inserting devices for flat wire stators have low efficiency due to the inability to automatically load, transfer, and wind flat wires, resulting in inefficient wire insertion processes.

Innovation Solution

An automatic wire inserting device is designed with a winding displacement tooling, material loading and transfer mechanisms, wire coiling mechanisms, and a wire inserting mechanism, which enables the loading, arrangement, and winding of flat wires in a stator slot, improving the efficiency of wire insertion through mechanical arms and motor-driven components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If an existing automatic wire inserting device is used, then wire inserting can be automated, but wire inserting efficiency is relatively low because the device cannot automatically load, transfer, and wind the flat wire

Engineering Contradiction:
Improveautomation of wire insertingVSAvoidwire inserting efficiency
Core Design Contradiction:
Extent of automationVSProductivity

Solution Approach 1:

The patent combines multiple previously separate operations (loading, transferring, winding, and inserting) into a single integrated device. The material loading mechanism loads flat wires, the material transfer mechanism transfers them to the winding displacement tooling, the wire coiling mechanism winds them into windings, and the wire inserting mechanism inserts them into the stator - all within one automated system that works continuously

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent implements continuous operation through the wire body that circularly moves the winding displacement tooling between the material transfer mechanism and the wire coiling mechanism. While one set of mechanisms is winding, another is loading or transferring, eliminating idle time and maintaining continuous productive action throughout the system

Inventive Principle:
Principle #20Continuity of useful action

2Productivity

If manual loading and transfer of flat wires is performed, then device complexity is reduced, but wire inserting efficiency decreases

Engineering Contradiction:
Improvewire inserting efficiencyVSAvoidcomplexity of loading and transfer mechanisms
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent divides the complex loading and transfer process into distinct functional modules: the material loading mechanism with vibration-generating parts, the material transfer mechanism with clamping assemblies, and the winding displacement tooling. Each module handles a specific task, making the overall complex system manageable and efficient

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces intermediary components such as the material holder that temporarily holds flat wires during transfer, and the clamping assemblies that securely grip the wires during manipulation. These intermediaries facilitate smooth transitions between different mechanisms without requiring direct complex interaction between all components

Inventive Principle:
Principle #24Intermediary (Mediator)
