Solution Overview

Problem

Existing cable laying systems are complex and expensive due to the use of robots, and there is a need for improvements in the efficiency and cost-effectiveness of laying cables on a form board.

Innovation Solution

A cable laying machine designed for laying cables onto a forming board with guide channels that correspond to the structure of the cable set, utilizing grippers and a simplified mechanical design with translational degrees of freedom, eliminating the need for robot arms and reducing complexity and cost.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If robots are used for cable laying, then automation is achieved, but device complexity and cost increase

Engineering Contradiction:
ImproveautomationVSAvoiddevice complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The system divides the cable laying task into two independent grippers (first gripper and second gripper) that operate separately but cooperatively. Each gripper handles one end of the cable, allowing independent control and simpler individual mechanisms compared to a single robotic arm system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of using a single complex robotic arm to manipulate the cable from one end, the system inverts the approach by using two simpler grippers that each hold one end of the cable and move in coordinated opposition, effectively distributing the complexity across two simpler components.

Inventive Principle:
Principle #13The other way round (Inversion)

2Extent of automation

If robots are used for cable laying, then automation is achieved, but cost increases

Engineering Contradiction:
ImproveautomationVSAvoidcost
Core Design Contradiction:
Extent of automationVSEase of manufacture

Solution Approach 1:

The system segments the expensive robotic manipulation task into two simpler, less expensive gripper mechanisms. Each gripper can be manufactured more economically than a full robotic arm, while together they achieve the same automated cable laying function.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system uses two identical or similar gripper designs rather than a single complex robotic arm. This standardization allows for economies of scale in manufacturing and maintenance, reducing overall system cost while maintaining automation.

Inventive Principle:
Principle #26Copying

3Manufacturing precision

If guide channels are used for cable placement, then manufacturing precision is improved, but device complexity increases

Engineering Contradiction:
Improvecable placement precisionVSAvoiddevice complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The guide channels act as an intermediary structure between the grippers and the final cable placement. The channels provide physical guidance and constraint that automatically ensure precise cable positioning without requiring complex control systems or sophisticated gripper mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The guide channels provide self-aligning and self-positioning functionality for the cables. As the grippers move the cables through the channels, the channels themselves enforce the correct final position, eliminating the need for complex positioning control systems.

Inventive Principle:
Principle #25Self-service
