Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual search and retrieval method is used to locate yarn spindles, then the system complexity is low, but the productivity is low and the time consumption is high

Engineering Contradiction:
Improveprocessing efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent replaces the manual mechanical search process with an automated image-based detection system. A detection model processes images of the parking area to automatically identify and locate yarn spindles, substituting human visual search and physical retrieval with computational image analysis and automated positioning, thereby dramatically improving productivity without requiring complex mechanical retrieval devices

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

Solution Approach 2:

The patent uses image copies (photographs or digital images) of the parking area and yarn spindles to create a virtual representation of the physical space. The detection model analyzes these image copies to locate yarn spindles, eliminating the need for direct physical interaction or complex mechanical search systems while maintaining accurate localization capability

Inventive Principle:
Principle #26Copying

2Measurement precision

If manual search method is used to find yarn spindles, then the device complexity is low, but the measurement precision of yarn spindle position is low

Engineering Contradiction:
Improvelocation accuracyVSAvoiddetection system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces manual visual search with an automated detection model that processes images to precisely identify yarn spindle positions. The model uses computer vision algorithms to detect and locate yarn spindles in images, providing accurate positional information without requiring complex mechanical measurement devices or manual searching

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

Solution Approach 2:

The patent introduces images as an intermediary medium between the yarn spindles and the detection system. Instead of directly detecting physical yarn spindles, the system captures images of the parking area and uses a detection model to analyze these images, creating an indirect but precise measurement pathway that improves location accuracy without requiring direct contact or complex physical sensors

Inventive Principle:
Principle #24Intermediary (Mediator)
