Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual selection of product images is used, then image selection accuracy can be maintained, but productivity deteriorates due to the vast number of products and images
Solution Approach 1:
The patent replaces the manual mechanical selection process with an automated computer vision system using deep learning models. The system processes product images through trained neural networks that automatically classify and select relevant images, eliminating the need for manual review while maintaining high accuracy through algorithmic decision-making.
Solution Approach 2:
The image classification system is self-training through active learning mechanisms. The system automatically identifies uncertain predictions, retrieves ground truth labels, and retrain s itself to improve performance over time without human intervention, enabling the system to serve itself while processing millions of images.
2Device complexity
If a single general image classifier is used, then device complexity is reduced, but measurement precision deteriorates due to varying product categories
Solution Approach 1:
The patent divides the image classification task into multiple specialized classifiers, each trained on specific product categories. This segmentation allows each classifier to focus on category-specific features and patterns, achieving higher precision for diverse product types while the overall system remains manageable through modular architecture.
Solution Approach 2:
The system employs a universal framework that can apply different specialized classifiers based on product category detection. The multi-functional architecture automatically selects or adapts the appropriate classifier for each image, maintaining system simplicity while achieving category-specific precision through a unified multi-purpose system.

AI summary
A method includes retrieving, by a processor in an image classification system, a plurality of product images from a memory. A first image classifier is applied to a first of the plurality of product images. The first of the plurality of product images is associated with a first category. A second image classifier is applied to a second of the plurality of product images. The second of the plurality of product images is associated with a second category. A first result of the first image classifier for the first of the plurality of product images is stored in the memory. A second result of the second image classifier for the second of the plurality of product images is stored in the memory.
