Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual design, pattern production, and sewing work are performed, then clothing can be produced with traditional craftsmanship, but manufacturing cost increases and production time extends
Solution Approach 1:
The patent uses 3D digital copying to create virtual patterns and clothing models that replicate traditional design processes. Digital pattern data is copied and manipulated in virtual space, eliminating repeated manual pattern making while preserving design intent. This allows multiple iterations without physical material consumption.
Solution Approach 2:
The patent replaces manual mechanical operations with computer-based 3D modeling systems. The mechanical processes of manual pattern drafting, physical sewing, and hands-on fitting are substituted with digital algorithms that automatically generate patterns, simulate sewing processes, and render 3D clothing visualizations.
2Adaptability or versatility
If manual pattern modification is performed repeatedly to adapt to different body sizes, then clothing can be customized for various sizes, but working time for product development increases
Solution Approach 1:
The patent creates a universal 3D digital pattern system that can adapt to multiple body sizes and types through parameter adjustment. A single base pattern can be digitally modified to fit different sizes by changing dimensional parameters, eliminating the need to create separate physical patterns for each size.
Solution Approach 2:
The patent utilizes parameter-based digital patterns where size adaptations are achieved by modifying numerical parameters (length, width, curvature) rather than redrawing entire patterns. This allows rapid adjustment of pattern dimensions to match different body measurements while maintaining the overall design structure.
3Device complexity
If 3D modeling is performed without considering overlapping prevention, then modeling process is simplified, but modeling failures occur due to overlapping of 3D shape of parts with body
Solution Approach 1:
The patent implements feedback mechanisms where the 3D modeling system continuously monitors the spatial relationship between clothing parts and body surfaces. When potential overlaps are detected, the system provides feedback to automatically adjust positioning or alert the user, ensuring accurate representation without manual intervention.
Solution Approach 2:
The patent applies preliminary anti-action by pre-configuring the 3D modeling system to prevent overlapping before it occurs. The system uses algorithms that anticipate potential collision between clothing parts and body surfaces, automatically adjusting positions or orientations to maintain proper spatial separation throughout the modeling process.

AI summary
A three-dimensional (3D) modeling method of clothing to arrange and display parts constituting clothing on a 3D space includes loading pattern data and body data, wherein the pattern data comprises information about one or more parts constituting the clothing, and the body data comprises a 3D shape of a body on which the clothing is to be put; displaying the 3D shape of the body based on the body data; and displaying the one or more parts on the 3D shape of the body based on the pattern data.
