Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If pattern pieces are arranged densely to maximize material usage, then material waste is reduced, but the complexity of arrangement and precision of positioning increases
Solution Approach 1:
The garment pattern is divided into multiple separate pattern pieces that can be independently arranged and optimized on the material. This segmentation allows for flexible positioning of each piece to maximize material utilization while maintaining manageable complexity in the arrangement process.
Solution Approach 2:
The system transitions from traditional two-dimensional pattern arrangement to three-dimensional spatial optimization by considering the vertical stacking and layering of pattern pieces. This dimensional expansion enables more efficient material usage by utilizing the third dimension for piece placement and organization.
2Manufacturing precision
If the number of pattern pieces is increased to improve garment fit and design, then pattern detail and quality improve, but material waste and production complexity increase
Solution Approach 1:
Adjacent pattern pieces that can be efficiently positioned next to each other are merged into combined units. This merging reduces the total number of separate pieces that need to be arranged and managed, thereby reducing material waste and production complexity while preserving the detailed design quality of individual pieces.
Solution Approach 2:
The system creates a universal arrangement framework that can accommodate multiple pattern pieces with different functions and designs. This framework allows diverse pieces to be organized efficiently together, achieving high pattern quality without proportionally increasing material waste or production complexity.
3Ease of manufacture
If traditional pattern creation methods are used, then simplicity and ease of creation are maintained, but pattern quality and material efficiency are insufficient
Solution Approach 1:
The system employs automated computational algorithms that perform the complex task of pattern arrangement and optimization self-service. The computer automatically calculates optimal piece positions, orientations, and groupings based on material dimensions and pattern requirements, eliminating the need for manual trial-and-error arrangement while delivering superior pattern quality and material efficiency.
Solution Approach 2:
The manual mechanical process of pattern arrangement and optimization is replaced with computational algorithms and software-based systems. This substitution transforms the physical manipulation of pattern pieces into digital calculations that automatically determine optimal arrangements, significantly improving both pattern quality and material efficiency while maintaining ease of use through computerized interfaces.

AI summary
An information processing system comprises a controller including a processor configured to execute each of the following steps. An acquisition step acquires data on a first pattern relating to a shape of a specific garment. An output step outputs, based on the data on the first pattern and reference information on production of the garment, data on a second pattern relating to the shape of the specific garment. The data on the second pattern includes shapes of two or more two-dimensional pieces of the specific garment, and an area where the pieces are disposed in such a manner that they do not overlap each other and that a total number of the pieces in the area is less than or equal to a predetermined threshold.
