Problem

Existing systems for lubricating cables lack efficient control over lubricant application, often resulting in inconsistent lubrication distribution and user intervention is required to manage lubricant flow, which can disrupt the lubrication process.

Innovation Solution

A system utilizing sensors associated with a spool to automatically control the dispensation of viscous lubricant onto a cable, with a pump and wireless signal transmission to adjust lubricant flow based on cable speed and length, and a custom bucket design for automatic lubricant application, ensuring consistent lubrication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual control of lubricant flow is used, then user intervention is required to manage lubrication, but this disrupts the lubrication process and reduces consistency

Engineering Contradiction:
Improvemanual controlVSAvoidlubrication consistency
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system employs a sensor associated with the spool to automatically detect cable draw speed and length, and the controller automatically adjusts the lubricant flow rate based on these detections, enabling the system to serve itself without manual intervention and maintaining consistent lubrication

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The sensor provides real-time feedback on cable draw speed and length to the controller, which then adjusts the lubricant flow rate accordingly, creating a closed-loop control system that ensures consistent lubrication application

Inventive Principle:
Principle #23Feedback

2Reliability

If automatic sensor control is implemented, then lubrication consistency is improved, but device complexity increases

Engineering Contradiction:
Improvelubrication consistencyVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The sensor associated with the spool serves multiple functions: it detects both cable draw speed and cable length, and this single sensor's data is used to control the entire lubrication process, reducing the need for multiple separate components

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

Solution Approach 2:

The controller integrates multiple control functions into a single device, combining the detection of cable parameters and the control of lubricant flow rate adjustment in one unit, thereby managing complexity through consolidation

Inventive Principle:
Principle #5Merging (Combining)

3Manufacturing precision

If lubricant flow is adjusted based on cable speed, then lubrication distribution becomes uniform, but control system complexity increases

Engineering Contradiction:
Improvelubrication distribution uniformityVSAvoidcontrol system complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The sensor continuously monitors cable draw speed and provides feedback to the controller, which automatically adjusts the lubricant flow rate in real-time to maintain uniform lubrication distribution without requiring complex manual control mechanisms

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The control system automatically regulates lubricant flow based on sensor input without requiring external intervention, enabling precise lubrication distribution through self-adjusting mechanisms

Inventive Principle:
Principle #25Self-service

AI summary

A lubricating system has a pump to force a viscous lubricant from a supply of lubricant to a lubricator at which the lubricant is to be dispensed onto a cable, wire, or the like that is being pulled through a conduit. A sensor, associated with a spool from which the cable is being dispensed, is be used to automatically control the amount of lubricant that is to be dispensed onto the cable. A second described system comprises a custom bucket or bucket insert which allow a cable to pass through the bucket whereupon lubricant will be automatically applied to the cable and the container includes a profiled base to ensure proper passage of the cable through the lubricant and ensure the maximum usage of any lubricant.
