Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If cable production processes are used without precision control, then production speed and flexibility are improved, but cable insulation layer thickness varies outside tolerance limits causing machinery damage

Engineering Contradiction:
Improvecable production speedVSAvoidinsulation layer thickness
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent implements a laser sensor measurement system that measures cable diameter and insulator jacket thickness in real-time during production. The system compares measurements against upper and lower tolerance limits before the cable proceeds to the wire-cutting machine, preventing out-of-tolerance cables from causing machinery damage while maintaining continuous production flow

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The control system receives measurement data from the laser sensor, compares it with predetermined tolerance limits, and provides feedback by sending signals to stop the cable or send alerts when measurements fall outside acceptable ranges. This closed-loop feedback mechanism ensures manufacturing precision without significantly reducing productivity

Inventive Principle:
Principle #23Feedback

2Productivity

If cable diameter is not monitored, then production flow is maintained, but cables outside upper tolerance limits cause machinery jamming and belt damage

Engineering Contradiction:
Improvecable production flowVSAvoidmachinery damage from oversized cables
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary measurement and verification of cable diameter using laser sensors before the cable enters the wire-cutting machine. By checking dimensions in advance and stopping the cable or sending alerts when out of tolerance, the system prevents oversized cables from jamming guide tubes or damaging belts, thereby protecting machinery while maintaining continuous production flow

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If cable insulation thickness is not monitored, then production is simplified, but cables below lower tolerance limits cause electrical hazards and fires

Engineering Contradiction:
Improveproduction monitoring systemVSAvoidelectrical hazards from thin insulation
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The laser sensor measurement system performs preliminary measurement of insulator jacket thickness before the cable reaches the wire-cutting machine. The control system compares measurements against lower tolerance limits and provides feedback by stopping the cable or sending alerts, preventing cables with insufficient insulation from causing electrical hazards or fires while maintaining manageable system complexity

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The control system implements a feedback mechanism that receives measurement data from the laser sensor, compares it with predetermined lower tolerance limits, and sends stop signals or alerts when measurements fall below acceptable ranges. This ensures electrical safety without significantly increasing device complexity

Inventive Principle:
Principle #23Feedback

AI summary

A system for cable abnormality detection is disclosed. The system includes a laser sensor measurement system for measuring a cable diameter and insulator jacket coating thickness of a cable and a guide assembly for guiding entry of the cable through the laser sensor measurement system. The system further includes a control system with a memory and a processor that executes computer-executable instructions and causes the processor to: measure the cable diameter with respect to upper limits of the cable diameter; determine that the cable diameter is outside of the upper limits using the cable diameter measurements and cable parameter tolerances; and initiate a signal to stop the cable from advancing, in response to determining that the cable diameter is outside of the upper limits.
