Double-Graded Waist and Hip Lower Garment Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional single-sized garment patterns fail to accommodate varying body shapes, leading to ill-fitting lower garments that can be uncomfortable and difficult to find in appropriate sizes, especially for individuals with different waist and hip measurements.
Innovation Solution
The implementation of double-graded patterns for lower garments, where the waist and hip portions can be sized independently, allowing for a greater range of sizes and combinations to better fit diverse body types, including junction lines that transition between different gradings, thereby increasing the number of possible patterns and improving fit without increasing material costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional single-sized garment patterns are used, then manufacturing is simple, but fit quality deteriorates for individuals with different waist and hip measurements
Solution Approach 1:
The patent divides the garment pattern into separate waist and hip grading systems. Instead of using a single unified pattern size, the invention segments the sizing into independent waist measurements and hip measurements, allowing each region to be sized appropriately for the wearer's specific body shape. This segmentation resolves the contradiction by enabling precise fit in both waist and hip areas without requiring an entirely complex new patterning system.
Solution Approach 2:
The patent applies different grading rules to different regions of the garment. The waist portion uses one grading system while the hip portion uses another grading system, allowing each local region to have the quality and dimensions appropriate for its specific function and the wearer's body characteristics. This local quality approach improves overall fit precision without uniformly complicating the entire pattern.
2Adaptability or versatility
If double-graded patterns with independent waist and hip sizing are implemented, then adaptability to different body shapes improves, but device complexity increases
Solution Approach 1:
By segmenting the pattern into independent waist and hip grading components, the invention achieves high adaptability to different body shapes. Each segment can be selected and combined based on the wearer's specific measurements, creating a versatile system that accommodates various body types without requiring a completely new pattern for each combination.
Solution Approach 2:
The double-graded pattern system serves multiple functions: it can accommodate any combination of waist and hip measurements within the defined ranges, work with standard manufacturing processes, and maintain compatibility with existing garment construction methods. This multi-functionality achieves high adaptability without proportionally increasing complexity.
3Adaptability or versatility
If more pattern combinations are created to fit diverse body types, then product variety increases, but manufacturing complexity increases
Solution Approach 1:
The segmented grading system allows patterns to be constructed from standardized modular components. Rather than creating entirely unique patterns for each size combination, the system segments the pattern into reusable waist and hip portions that can be systematically combined, maintaining manufacturing efficiency while expanding size range.
Solution Approach 2:
The invention changes the parameters of pattern generation from fixed single sizes to variable double-graded combinations. By establishing systematic grading rules for waist and hip measurements, the system can generate appropriate patterns for diverse body types through parameter variation rather than requiring completely new pattern designs, thus preserving manufacturing productivity.
