Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional imaging systems are used to capture product images, then image capture is achieved, but object identification capability is lacking

Engineering Contradiction:
Improveobject identification accuracyVSAvoidimage processing capability
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces a separate machine learning processing system that acts as an intermediary between the imaging system and the identification output. The imaging system captures images, which are then processed by the external machine learning model to identify objects. This separates the capture function from the identification function, allowing each to be optimized independently.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional mechanical or algorithmic image processing methods with machine learning-based object recognition. Instead of using conventional computer vision algorithms that require complex processing, the system uses trained machine learning models that can identify objects more accurately with simpler processing pipelines.

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

2Measurement precision

If significant image processing capabilities are used to identify products, then identification accuracy improves, but processing time and computational resources increase

Engineering Contradiction:
Improveproduct identification accuracyVSAvoidprocessing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies machine learning models that have been pre-trained on extensive product datasets before deployment. This preliminary training phase allows the model to learn complex product patterns and features in advance, so that during actual product identification, the processing is much faster and requires less computational effort while maintaining high accuracy.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If traditional imaging systems are used, then hardware simplicity is maintained, but object recognition capability is insufficient

Engineering Contradiction:
Improveobject recognition capabilityVSAvoidsystem architecture
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the system into distinct functional segments: an imaging system that captures images and a separate machine learning processing system that performs identification. This segmentation allows the imaging hardware to remain relatively simple while the intelligence is concentrated in the software-based machine learning component, achieving high adaptability without proportionally increasing hardware complexity.

Inventive Principle:
Principle #1Segmentation
