Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for making clothing are limited in their ability to adjust size to fit individual morphology, resulting in restricted adjustability and increased fabric waste due to the use of curved edges and complex patterns.
Innovation Solution
A process involving the production and assembly of multiple strips of fabric with parallel longitudinal edges, connected by seams that allow for variable width adjustment along the strips, enabling precise fitting and adaptation to different body measurements without the need for paper patterns or complex cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional curved edge pieces are used to form clothing articles, then the clothing can achieve specific size shapes, but the adjustability of size is limited and fabric waste increases
Solution Approach 1:
The invention divides the clothing article into multiple straight-edged pieces (first, second, third pieces) that can be independently sized and shaped. Each piece has straight edges that meet at seams, allowing independent adjustment of each piece's dimensions while maintaining the overall clothing shape. This segmentation enables size adjustment without requiring complex curved patterns.
Solution Approach 2:
The invention changes the fundamental parameters of the clothing construction by using straight-edged pieces instead of curved-edged pieces. The straight edges allow for variable sizing through simple dimensional changes in each piece, while the seams connect these pieces to form the complete article. This parameter change from curved to straight edges enables both manufacturing precision and size adaptability.
2Strength
If reserve fabric is added to connecting seams to prevent tearing, then the strength of the clothing is improved, but the adjustability of size is reduced
Solution Approach 1:
The invention segments the connecting seams into adjustable components where the first, second, and third pieces can be independently sized. The seams connect these segmented pieces with straight edges, allowing the reserve fabric to be distributed across multiple adjustable seams rather than limiting the overall size adjustment capacity of the garment.
Solution Approach 2:
The invention introduces dynamic adjustability to the connecting seams by making each piece (first, second, third) independently sizeable. The seams connect these dynamic components, allowing the reserve fabric to be utilized across multiple adjustable points, thereby maintaining both strength through reserve fabric and adaptability through variable sizing of each piece.
3Ease of manufacture
If multiple pieces of fabric with curved edges are assembled, then the clothing article can be formed, but the complexity of the shape increases and adjustability is limited
Solution Approach 1:
The invention inverts the traditional approach by using straight-edged pieces instead of curved-edged pieces to form the clothing article. The straight edges are joined at seams to create the desired shape, reversing the conventional method where curved edges define the shape. This inversion simplifies the manufacturing process and enables easier size adjustment while maintaining article formation capability.
Solution Approach 2:
The invention changes the geometric parameters of the fabric pieces from curved edges to straight edges. This parameter change simplifies the shape definition to basic geometric forms that are easier to manufacture and adjust. The clothing article shape is achieved through the arrangement and connection of these simplified straight-edged pieces rather than complex curved patterns.
4Productivity
If paper patterns are used to reproduce the model, then the clothing can be standardized, but the adaptability to individual morphology is reduced
Solution Approach 1:
The invention segments the clothing model into multiple independent pieces (first, second, third pieces) with straight edges. Each piece can be independently sized and shaped according to individual measurements, eliminating the need for complex paper patterns. This segmentation allows standardization of the piece construction process while maintaining adaptability to individual morphology through variable dimensions of each piece.
5Manufacturing precision
If curved edge shapes are used for each piece, then the specific size shape is achieved, but redefining curves is required for different sizes
Solution Approach 1:
The invention inverts the traditional approach by using straight-edged pieces instead of curved-edged pieces. The straight edges provide manufacturing precision through simple geometric definitions, while the arrangement and connection of these straight-edged pieces at seams create the desired shape. This inversion eliminates the need to redefine curves for different sizes, as straight edges can be easily adjusted in length and position.
