Solution Overview

Problem

Existing cable dispensing systems face challenges with handling heavy and cumbersome drums, leading to damage of the outer insulation layer when dragged over rough ground, and require additional equipment like cable rollers and stringers for efficient dispensing.

Innovation Solution

A cable dispensing vehicle with a frame, ground contact wheels, opposed drum arms, a cable shield, and powered drive wheel, which allows for dispensing cable from the underside of the drum, reducing the need for additional rollers and shielding the cable from ground debris.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If cable is dispensed from a drum over rough ground, then cable dispensing is achieved, but the outer insulation layer is damaged

Engineering Contradiction:

Improvecable dispensing efficiencyVSAvoidcable insulation integrity

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

A shield is introduced as an intermediary component between the cable and the rough ground. The shield extends from the drum to the ground, creating a protective barrier that prevents direct contact between the cable insulation and ground debris, thus resolving the contradiction between dispensing efficiency and insulation integrity

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The shield adds a spatial dimension to the cable dispensing system by extending vertically from the drum down to the ground. This creates a protective three-dimensional space that encompasses the cable path, preventing ground-level hazards from damaging the cable while maintaining dispensing efficiency

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Ease of operation

If cable rollers and stringers are used to convey cable, then cable dispensing is improved, but device complexity increases

Engineering Contradiction:

Improvecable dispensing easeVSAvoidnumber of additional equipment

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The shield combines multiple functions into a single component: it protects the cable from ground damage, guides the cable from the drum, and eliminates the need for separate rollers and stringers. This merging of functions improves ease of operation while reducing device complexity

Inventive Principle:

Principle #5Merging (Combining)

3Productivity

If drum is supported by opposed drum arms, then cable dispensing is achieved, but handling heavy drum becomes cumbersome

Engineering Contradiction:

Improvecable dispensing capabilityVSAvoiddrum handling ease

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The opposed drum arms are designed to balance the weight of the heavy drum through counterbalancing mechanical advantage. The opposing arms distribute the load symmetrically, reducing the effort required to handle and position the drum while maintaining cable dispensing capability

Inventive Principle:

Principle #8Anti-weight (Counterweight)
