Curved Waistband Structure to Prevent Back Exposure When Bending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing garments, particularly low-rise trousers and jeans, fail to prevent the exposure of the buttock and intergluteal cleft when the wearer bends forward, and this issue is exacerbated in overweight individuals.
Innovation Solution
A non-linear waistband device with a supporting mechanism that applies tension to the back section of the trousers, ensuring it remains vertical even when the wearer bends forward, using a body with a perimeter defined by an upper and lower side, where the lower side is longer, and a middle portion that bends upward to distal ends, optionally in crescent, V, or parentheses shapes, and can be detachable for ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a linear waistband is used in low-rise jeans, then the garment can be worn with a lower waistline for fashion purposes, but the buttock and intergluteal cleft are exposed when the wearer bends forward
Solution Approach 1:
The waistband is designed with a non-linear curved path that follows the contour of the wearer's body, specifically dipping lower at the front and rising higher at the back. This curvature allows the waistband to maintain coverage of the buttock area when bending forward while still enabling low-rise styling at the front waistline.
2Adaptability or versatility
If a linear waistband is used for overweight individuals with protruding abdomens, then the garment can be worn, but the waistband is pushed downward causing the back to be too low and exposing the buttock when bending over
Solution Approach 1:
The non-linear curved waistband path accommodates protruding abdomens by allowing the front section to sit lower on the abdomen while the back section maintains higher coverage. This curvature prevents the waistband from being uniformly pushed downward, keeping the back section in proper position to prevent buttock exposure.
3Object-affected harmful factors
If suspenders are used to hold the front of blue jeans up high for overweight individuals, then the front coverage is maintained, but the device becomes more complex and uncomfortable
Solution Approach 1:
The waistband integrates both front and back support functions into a single continuous non-linear structure. The curved design inherently provides the lifting effect previously requiring separate suspenders, while maintaining coverage at both front and back without additional components.
4Ease of manufacture
If a conventional linear waistband is used, then the manufacturing process is simple, but the waistband does not maintain proper vertical alignment when the wearer bends forward
Solution Approach 1:
The waistband is constructed with a predetermined non-linear curved shape that maintains the vertical alignment relationship between front and back sections. This inherent curvature design ensures proper positioning during bending movements while remaining manufacturable through standard cutting and sewing processes.

AI summary
The invention provides a device capable of incorporating into or attachable to a garment to provide a non-linear waistband. The device includes a body (120) having a perimeter defined by an upper side (112) and a lower side (111) with respect to the garment when incorporated, the lower side having a greater length than the upper side, the body being shaped to define a middle portion (130) that bends upward to two distal ends (131,132). The garment has a non-linear waistband (210) such that a front section (211) is lower than a back section (214) and two side sections (212, 213). The two distal ends are arranged to hold the two side sections of the garment, and the middle portion is arranged to hold the front section of the garment. A tension force is applied by the two side sections to hold the back section in place when the wearer is bending forward.
