Solution Overview

Problem

Conventional image recognition systems in cable processing plants struggle to reliably identify cable types under varying lighting conditions and are prone to false positives when components are rotated or positioned incorrectly, leading to errors in cable processing.

Innovation Solution

A trainable algorithm, such as a convolutional neural network, is used to identify predefined features in cable end images without the need for additional image processing, allowing for flexible error detection and improved accuracy regardless of component orientation or lighting conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional image recognition systems are used to detect cables under varying lighting conditions, then the system can operate continuously, but the reliability of cable identification deteriorates due to false positives and misidentification

Engineering Contradiction:
Improvecontinuous operation capabilityVSAvoidcable identification accuracy
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent transforms the rigid parameter-based detection of conventional systems into a flexible, learned parameter recognition approach. The neural network is trained on diverse images with varying lighting conditions, cable types, and orientations, enabling it to automatically adapt to parameter changes without false positives. This resolves the contradiction by maintaining continuous operation while improving identification reliability through learned invariance to environmental variations.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent replaces the mechanical/image-processing-based conventional recognition system with an intelligent neural network system. Instead of using fixed algorithms that require precise positioning and controlled lighting, the neural network substitutes these mechanical constraints with learned patterns, enabling reliable identification under varying conditions while maintaining continuous productivity.

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

2Measurement precision

If conventional image processing systems require precise component positioning, then measurement precision can be maintained, but the system complexity increases and flexibility decreases

Engineering Contradiction:
Improvefeature detection accuracyVSAvoidimage processing requirements
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces dynamics by replacing static, position-dependent image processing with a dynamic neural network that adapts to varying cable positions and orientations. The system no longer requires fixed positioning mechanisms or complex image alignment procedures, as the neural network learns to recognize features regardless of their position or orientation in the image, thereby reducing device complexity while maintaining detection accuracy.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The neural network serves multiple functions simultaneously: it detects various cable types, identifies different features, handles various lighting conditions, and accommodates different positions and orientations all within a single system. This universal approach eliminates the need for multiple specialized image processing algorithms and positioning mechanisms, reducing overall system complexity while maintaining high measurement precision.

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

3Reliability

If trainable algorithms are implemented for flexible error detection, then reliability improves under varying conditions, but the initial setup and training complexity increases

Engineering Contradiction:
Improveerror detection accuracyVSAvoidalgorithm training process
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by training the neural network in advance with comprehensive datasets covering all expected cable types, lighting conditions, and positions. This one-time preliminary training phase creates a robust model that requires no complex adjustments during operation. The upfront investment in training data collection and model development resolves the contradiction by establishing high reliability that persists through continuous operation without requiring ongoing complex configuration.
