Solution Overview

Problem

Existing devices for automatic heading of electrical wiring with insulation displacement (IDC) connectors lack the ability to efficiently handle free leads of recovered wires, leading to manual intervention, increased time and costs, low quality, and reduced productivity due to limited adaptability and configurability.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual intervention is used for heading free leads of recovered wires, then flexibility and adaptability are maintained, but time consumption increases and productivity decreases

Engineering Contradiction:
ImproveadaptabilityVSAvoidproductivity
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The device segments the heading process into distinct modular stations (stripping station, heading station, tinning station, etc.), allowing each function to be independently optimized while maintaining overall system flexibility. This enables automated processing of multiple wire types and heading configurations without requiring complete manual intervention.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The device employs dynamic elements including a rotating head that can position wires at different angles, adjustable pressing elements that adapt to various wire diameters, and a programmable control system that dynamically configures the heading process parameters. This dynamic adaptability replaces manual flexibility while maintaining productivity.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If manual heading of free leads is performed after crimping, then various heading configurations can be achieved, but error risk increases and quality consistency decreases

Engineering Contradiction:
ImproveconfigurabilityVSAvoidquality
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The device performs self-service through automated wire feeding, positioning, stripping, heading, and tinning operations. The programmable control system automatically configures the process parameters based on the selected wire type and desired heading configuration, eliminating manual intervention errors while maintaining full configurability for different wire specifications.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The device incorporates feedback mechanisms including sensors that detect wire position, diameter, and heading formation quality. This feedback is fed back to the control system which automatically adjusts process parameters to maintain consistent quality across different heading configurations, preventing errors before they occur.

Inventive Principle:
Principle #23Feedback

3Productivity

If automated wire loading and transfer is used, then productivity increases, but the ability to handle wires requiring non-IDC heading is limited

Engineering Contradiction:
ImproveproductivityVSAvoidversatility
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The device achieves universality by integrating multiple heading capabilities into a single automated system. The rotating head with multiple positioning stations can accommodate IDC connectors, crimped terminals, sleeves, and other heading types. The programmable control system allows the same wire feeding and transfer mechanism to handle different wire types and heading configurations, making the device versatile while maintaining high productivity.

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

4Adaptability or versatility

If multiple heading stations are added to provide complete discretionality on terminals, then adaptability improves, but device complexity increases

Engineering Contradiction:
ImprovediscretionalityVSAvoidcomplexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device segments the heading functionality into modular, interchangeable stations that can be independently configured. Each station handles a specific heading operation (stripping, heading, tinning, etc.), and the modular design allows these segments to be arranged in different sequences or configurations based on the required discretionality, managing complexity through functional decomposition.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The device manages complexity by changing operational parameters (rotation position, pressing force, heating temperature, timing sequences) rather than adding physically complex mechanisms. The programmable control system adjusts these parameters to achieve different heading configurations, providing complete discretionality through software control rather than mechanical complexity.

Inventive Principle:
Principle #35Parameter changes
