Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If laser body-scanning systems are used to create three-dimensional models, then measurement precision is improved, but device complexity and cost increase significantly
Solution Approach 1:
The patent uses a printed pattern on a garment as a two-dimensional copy that maps to the three-dimensional body surface. The pattern elements serve as surrogate features that can be detected in images to infer three-dimensional geometry, replacing the need for complex laser scanning equipment while maintaining modeling accuracy.
Solution Approach 2:
The patent replaces the mechanical laser scanning system with an optical imaging system using ordinary digital cameras. Instead of using lasers to directly measure the body, the system uses cameras to capture images of a patterned garment, then computationally extracts three-dimensional information from these two-dimensional images through feature detection and correlation.
2Measurement precision
If laser body-scanning systems are used, then model accuracy is improved, but ease of operation deteriorates due to invasive procedures and special facilities
Solution Approach 1:
The patent enables consumers to perform body measurement themselves at home using ordinary digital cameras and a patterned garment. The system provides instructions for capturing images from multiple angles, and automated algorithms process these images to create three-dimensional models, eliminating the need for specialized facilities and expert operators.
Solution Approach 2:
The patent uses a disposable printed pattern on a garment instead of expensive, complex laser scanning equipment. The pattern elements are inexpensive and can be easily printed on standard fabric, making the system accessible to consumers while maintaining the ability to extract accurate three-dimensional body geometry.
3Ease of operation
If key-in measurement systems are used, then ease of operation is improved, but measurement precision and reliability deteriorate due to laborious processes and errors
Solution Approach 1:
The patent introduces a printed pattern as an intermediary element that bridges the gap between simple image capture and accurate three-dimensional modeling. The pattern elements serve as reference markers that are easily detectable in images but encode sufficient geometric information to accurately reconstruct the three-dimensional body shape, eliminating the need for complex manual measurements while ensuring precision.
Solution Approach 2:
The patent replaces manual measurement taking with automated image processing. Instead of requiring consumers to physically measure body parts and input data manually (which is laborious and error-prone), the system uses computers to automatically detect pattern elements in images and compute three-dimensional models, significantly improving both ease of operation and measurement precision.
4Ease of manufacture
If standardized clothing sizes are used, then ease of manufacture is improved, but adaptability to individual bodies deteriorates
Solution Approach 1:
The patent transforms static standardized clothing sizes into dynamic, personalized fit solutions. By capturing individual body geometry through image processing of patterned garment images, the system can adapt standard clothing patterns and designs to match each consumer's unique body shape, enabling both ease of manufacture and high adaptability.

Data Source
AI summary
Images are made of a surface, and images are made of a covering (in the form of a reference object) having a pattern that includes an array of locally non-repetitive pattern elements. A three-dimensional models of the pattern elements on the covering is created using the images. A correlation in scaling between the process of generating three-dimensional models of the pattern elements on the covering and the process of generating a three-dimensional model of the surface is known, and this known correlation in scaling and the known actual distances among pattern elements on the covering can be used as a dimensional scale reference to determine dimensional information of the three-dimensional model of the surface.
