Solution Overview

Problem

Existing cable drum handling tools pose safety risks and are inefficient, requiring manual control for cable payout and drum rotation, and are cumbersome for switching between drums or tools, especially in field conditions.

Innovation Solution

A cable drum feeding tool with a primary gripper arm arrangement, actuation means, and a rotation mechanism that allows for automatic attachment and detachment from various construction vehicles, enabling remote operation and quick switching between cable drums without manual intervention, utilizing a connection mechanism with conical and plate members for secure engagement with the drum flanges.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a freely hanging suspension tool with a long shaft is used for cable drum handling, then the drum can be lifted and rotated, but manual involvement is required for safety control and orientation, and switching between drums is time-consuming

Engineering Contradiction:
Improvemanual control requirementVSAvoidsafety risk
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The tool is designed to automatically attach to the cable drum flange using a connection element with engaging elements that self-align and secure to the flange's opening, eliminating the need for manual positioning and attachment. The tool independently performs the attachment function without requiring operator intervention near the drum.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The operator is extracted from the dangerous zone near the drum by enabling remote operation from the vehicle cabin. The tool executes all attachment, positioning, and operation functions autonomously, removing the need for personnel to physically control the drum or monitor cable payout in the field.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If a long shaft attachment rod is used for drum attachment, then the drum can be secured to the lifting device, but switching between different drums or tools becomes cumbersome and time-consuming

Engineering Contradiction:
Improvedrum attachment securityVSAvoidswitching time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The attachment system is segmented into a modular connection element with separate engaging elements that can independently connect to the drum flange. This modular design allows for quick engagement and disengagement, enabling rapid switching between different drums or tools without requiring complete reattachment procedures.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection element is pre-configured with engaging elements positioned to automatically align with and secure to the drum flange opening. This preliminary positioning ensures that attachment occurs instantly when the tool approaches the drum, eliminating time-consuming manual alignment and securing operations.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If manual control is used for cable payout and drum rotation, then the operator can control the operation, but safety risks increase and operational efficiency decreases

Engineering Contradiction:
Improvecontrol capabilityVSAvoidoperational efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

Manual mechanical control operations are replaced with an automated system where the attachment tool is controlled from the vehicle cabin. The operator uses the vehicle's existing control mechanisms to remotely operate the tool, eliminating the need for manual field operations while maintaining full control capability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Extent of automation

If a specialized automatic cable reel is used, then automation is achieved, but the device is not suitable for field conditions such as construction sites

Engineering Contradiction:
Improveautomation levelVSAvoidfield condition suitability
Core Design Contradiction:
Extent of automationVSAdaptability or versatility

Solution Approach 1:

The tool is designed with universal compatibility to work with various cable drum configurations and can be integrated with different vehicle lifting devices. The connection element adapts to standard drum flange openings, and the tool can perform multiple functions including attachment, cable feeding, and operation control, making it suitable for diverse field conditions without requiring specialized infrastructure.

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