Single-Leg Tight Structure for Reversible Wear and Less Waste
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tights are delicate, prone to damage, generate significant waste, and are not suitable for users with only one leg, leading to discomfort and hygiene issues, with single-leg designs often requiring pairs and causing material waste.
Innovation Solution
A single-leg tight design featuring a leg section and a waist section with an opening for the second leg, allowing for reversible wear and reduced material use, incorporating varying materials and constructions for enhanced durability and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional tights are made to cover the entire body below the waist, then they provide complete leg coverage, but they generate significant material waste due to being easy to damage and requiring replacement
Solution Approach 1:
The patent divides the traditional two-legged tight into separate single-leg units, each with its own waist section and leg section. This segmentation allows each unit to be optimized for durability while covering only the necessary area, reducing material waste when one leg is damaged.
Solution Approach 2:
The patent changes the configuration parameter from two-legged to single-leg coverage, fundamentally altering how the garment is structured and worn. This parameter change enables reduced material usage while maintaining functional integrity.
2Loss of substance
If conventional tights are made as single-leg designs, then they reduce material waste, but they require pairs and still cause material waste
Solution Approach 1:
The single-leg tight is designed with universal applicability through its waist section that can accommodate either leg, and the leg section that can be worn on the engaged side or disengaged side. This multi-functionality eliminates the need for pairs while maintaining versatility.
Solution Approach 2:
The patent employs asymmetrical design where the waist section has an engaged side and disengaged side, allowing the same garment to be worn on different legs or configurations. This asymmetry enables single-unit versatility without requiring pairs.
3Ease of operation
If conventional tights cover the entire waist and pelvic region, then they provide comprehensive coverage, but they cause discomfort and hygiene issues during use
Solution Approach 1:
The patent extracts the crotch area coverage from the traditional tight design by introducing an opening in the crotch region. This extraction eliminates the hygiene issues and discomfort associated with covering the entire pelvic region while maintaining leg coverage.
Solution Approach 2:
The tight is segmented into distinct functional zones: the waist section for securing, the leg section for coverage, and the opening in the crotch region for hygiene. This segmentation allows each zone to perform its function optimally without compromising comfort or hygiene.
4Ease of operation
If single-leg tights are secured with a strap across the midsection, then they can be held in place, but they cause discomfort and an unattractive appearance
Solution Approach 1:
Instead of using a diagonal strap across the midsection to secure the tight, the patent inverts the approach by having the waist section naturally accommodate the leg through its engaged and disengaged sides. This inversion eliminates the need for uncomfortable diagonal straps.
Solution Approach 2:
The waist section is designed with multi-functionality to provide both the securing function and the structural support needed for comfortable wear. The engaged side and disengaged side configuration allows the same structure to serve multiple purposes without requiring additional uncomfortable straps.
