Innovation Solution

A flat copper wire stator wire coiling device with a tooling conveying mechanism, a winding mechanism, and guiding portions that include a wire routing and guiding system with adjustable components to facilitate continuous and effective winding of flat copper wire, utilizing a manipulator for positioning and a rotating assembly with variable diameters to secure the wire.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual winding of flat copper wire is used, then the existing device structure is simple, but the processing efficiency is low and labor intensity is high

Engineering Contradiction:
Improveprocessing efficiencyVSAvoiddevice structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The wire routing portion and wire guiding portion are designed to automatically guide and route the flat copper wire through the winding process without manual intervention. The wire body conveys tooling automatically, and the sliding mechanisms self-adjust to maintain wire tension and positioning, enabling continuous automatic winding operation

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The winding device is divided into distinct functional modules: tooling conveying mechanism with wire body, winding mechanism with rotating assembly, wire routing portion with sliding components, and wire guiding portion. Each module performs a specific function and can operate independently, allowing for efficient automated wire winding while maintaining manageable system complexity

Inventive Principle:
Principle #1Segmentation

2Productivity

If continuous winding operation is implemented, then productivity increases, but the wire may come off during winding

Engineering Contradiction:
Improvecontinuous winding capabilityVSAvoidwire positioning stability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The wire routing portion and wire guiding portion are designed to slide along the left-right direction dynamically adjusting their positions during the winding process. This dynamic adjustment ensures continuous wire guidance and prevents wire dislodgement while maintaining continuous operation capability

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The sliding mechanisms of the wire routing and wire guiding portions respond to wire tension and positioning feedback during winding, automatically adjusting their positions to maintain proper wire alignment and prevent wire from coming off during continuous operation

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If fixed diameter winding assembly is used, then the structure is simple, but it cannot adapt to different wire winding requirements

Engineering Contradiction:
Improvewinding diameter adjustabilityVSAvoidwinding mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The rotating assembly is designed with variable inner and outer diameters that can be adjusted dynamically. The insertion pieces can be positioned at different locations on the sleeve to change the effective winding diameter, allowing the same winding mechanism to handle different wire specifications and winding requirements without structural modification

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The winding mechanism with adjustable diameter capability serves multiple functions: it can wind different sizes of flat copper wire, accommodate different winding patterns, and adapt to various stator core configurations. This multi-functionality is achieved through the adjustable insertion pieces and sliding mechanisms that provide versatility without requiring multiple dedicated winding devices

Inventive Principle:
Principle #6Universality (Multi-functionality)
