Clothing with Back Body Chest Width Reduction for Posture Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional functional clothing designed to improve posture by applying different loads on the body is limited by the need for multiple materials, which restricts variety, productivity, and comfort, often resulting in poor performance and ease of use.
Innovation Solution
The clothing uses a single material for both the front and back bodies, with a shorter chest width in the back body to create a greater elongation and stretching stress, allowing the scapulae to be drawn towards the center, improving posture without the need for multiple materials, thus enhancing productivity and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple materials with different stretching stress are used to vary strength from site to site, then posture correction effect is improved, but material variety is restricted and productivity deteriorates
Solution Approach 1:
The patent applies local quality by creating a cutting out portion at a specific location on the back body (between scapulae) to generate localized stretching stress. This allows different functional properties at different locations using the same material - the cutting out portion area experiences greater elongation and stretching stress to draw scapulae to the center, while other areas maintain normal fit, thus achieving posture correction effect with single material
Solution Approach 2:
The patent changes the geometric parameter of the clothing structure by reducing the chest width of the back body compared to the front body. This parameter change creates the cutting out portion that generates the desired stretching stress distribution, allowing the same material to provide different functional effects at different locations without requiring multiple materials
2Reliability
If multiple materials with different stretching stress are used to vary strength from site to site, then posture correction effect is improved, but material variety is restricted
Solution Approach 1:
The patent uses local quality by implementing a cutting out portion at a specific location on the back body to create localized functional properties. The same material exhibits different mechanical behavior at the cutting out portion area versus other areas, enabling posture correction functionality without restricting material selection
Solution Approach 2:
The patent applies universality by using a single material that serves multiple functions: it provides general clothing coverage, comfort, and simultaneously creates localized posture correction effect through the cutting out portion design. The same material and construction method can be applied across different clothing types and material selections
3Reliability
If firm pressure is applied to improve posture, then posture correction effect is improved, but wearing comfort deteriorates
Solution Approach 1:
The patent applies local quality by concentrating the stretching stress effect at the cutting out portion location (between scapulae) rather than applying firm pressure across the entire garment. This localized approach provides posture correction where needed while maintaining comfort in other areas, avoiding the discomfort of overall tightness
Solution Approach 2:
The patent uses partial action by applying stretching stress only at the specific cutting out portion area rather than uniformly across the entire back body. This partial application of force is sufficient to draw scapulae to the center and improve posture without the excessive pressure that would cause discomfort
4Reliability
If tight-fit fabric is used to apply stretching stress, then posture correction effect is improved, but ease of putting on and taking off deteriorates
Solution Approach 1:
The patent uses local quality by creating the cutting out portion only at the back body between scapulae, allowing stretching stress to be generated locally without requiring the entire garment to be tight-fit. This localized design provides posture correction functionality while maintaining ease of putting on and taking off in the rest of the garment

AI summary
Clothing has a body including a front body and a back body, wherein a material constituting the front body and a material constituting the back body are the same, and a chest width of the back body is shorter than a chest width of the front body. The clothing guides a motion or state of the upper body of a wearer to a proper posture and improves motion followability and wearing comfort around scapulae.
