Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional manual sizing methods are used, then users can find size-specific items, but the process is time-consuming and inaccurate

Engineering Contradiction:
Improvesizing accuracyVSAvoidtime to determine matching items
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces manual sizing measurement methods with image processing technology. The system captures images of users and automatically determines their body dimensions through computer vision algorithms, eliminating the need for manual measurement while improving both accuracy and speed of sizing determination.

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

Solution Approach 2:

The system enables users to automatically obtain their sizing information through self-captured images. Users take photos of themselves using their devices, and the system automatically processes these images to extract sizing data without requiring user input or manual measurement, making the process both rapid and accurate.

Inventive Principle:
Principle #25Self-service

2Reliability

If comprehensive sizing data collection is implemented, then matching accuracy improves, but system complexity increases

Engineering Contradiction:
Improveitem matching reliabilityVSAvoidsizing data collection system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent makes the image processing system multi-functional by using a single image capture mechanism to extract multiple sizing parameters simultaneously. The same image processing algorithms determine various body dimensions (height, waist, hips, etc.) from one image, eliminating the need for separate measurement devices for each parameter and reducing overall system complexity.

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

Solution Approach 2:

The system introduces an image as an intermediary medium between the user and the sizing data. Instead of directly measuring users with multiple specialized devices, the system uses images as a universal intermediary that can be captured by common devices (smartphones, cameras) and then processed to extract comprehensive sizing information, simplifying the data collection infrastructure.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Extent of automation

If image-based sizing is used, then sizing determination becomes automated and accurate, but computing resources increase

Engineering Contradiction:
Improvesizing determination automationVSAvoidcomputing resource consumption
Core Design Contradiction:
Extent of automationVSUse of energy by moving object

Solution Approach 1:

The system applies partial action by processing only the essential features needed for sizing determination from images, rather than performing exhaustive analysis. The image processing algorithms focus specifically on extracting body dimension information relevant to clothing sizing, avoiding unnecessary computational overhead while maintaining automation and accuracy.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The system performs preliminary action by pre-processing and storing sizing data in structured formats during image analysis. By organizing sizing information in advance with proper metadata and relationships, the system reduces the computational burden during subsequent item matching operations, as the sizing data is already prepared and indexed for efficient comparison.

Inventive Principle:
Principle #10Preliminary action
