Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual inspection tools (magnifying glass, stereoscope, X-ray, CT, AOI) are used to detect counterfeit components, then detection capability is improved, but inspection speed and productivity deteriorate

Engineering Contradiction:
Improvecounterfeit detection capabilityVSAvoidinspection speed
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent replaces manual mechanical inspection tools (magnifying glass, stereoscope) and even automated optical inspection systems with a machine learning-based image analysis system. The system captures images of component leads and uses trained ML models to automatically detect counterfeit components, eliminating the need for human operators to manually examine each component while achieving both high detection accuracy and rapid processing speeds.

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

Solution Approach 2:

The patent creates digital copies (images) of the physical component leads and analyzes these copies using machine learning algorithms. Instead of physically manipulating or closely examining the actual components, the system processes digital representations, enabling parallel processing of multiple components simultaneously and dramatically increasing inspection throughput while maintaining detection accuracy.

Inventive Principle:
Principle #26Copying

2Measurement precision

If manual inspection is performed on random samples from a batch, then some counterfeit components may be detected, but the majority of counterfeit components remain undetected and reliability deteriorates

Engineering Contradiction:
Improvecounterfeit detection accuracyVSAvoidbatch quality assurance
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent performs preliminary inspection of all components in a batch before assembly or shipment. By examining every component lead image through the machine learning system prior to final product completion, the system identifies and flags counterfeit components early in the process, preventing defective components from being assembled into finished products and ensuring high batch quality assurance.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent segments the inspection process into distinct analytical stages: image capture of individual lead features, feature extraction and processing, ML model classification of each component, and batch-level aggregation of results. This segmentation enables comprehensive inspection of all components while maintaining detailed traceability and allowing for different inspection strategies at different stages of the manufacturing process.

Inventive Principle:
Principle #1Segmentation

3Productivity

If automated machine learning assessment is implemented for all components, then inspection speed and productivity are improved, but detection precision may deteriorate compared to expert manual inspection

Engineering Contradiction:
Improvemass inspection capabilityVSAvoidsolderability assessment accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The patent implements a preliminary training phase where the machine learning system is trained on extensive datasets of component images with known solderability outcomes. This preliminary training with labeled examples enables the system to learn expert-level assessment criteria before deployment, ensuring that the automated system achieves detection precision comparable to or exceeding human expert inspection while maintaining high throughput capability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent incorporates feedback mechanisms where the machine learning system continuously improves its assessment accuracy. Results from automated inspections are fed back into the training process, allowing the system to learn from real-world performance and refine its classification algorithms. This feedback loop enables the system to maintain and improve detection precision over time while operating at high speeds.

Inventive Principle:
Principle #23Feedback
