Curved Buckling Line Antiperspirant Insert for Garment Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antiperspirant pads face issues with tearing and imprecise fit when attempting to conform to the curved shape of clothing, leading to discomfort and bulkiness due to their flat design and material tension during folding.
Innovation Solution
An antiperspirant insert with curved predetermined buckling lines that automatically force the halves into a three-dimensional curved position, allowing for easier adaptation to the body's curvature and improved fit, featuring oblique fold lines and a taper or perforation for simplified folding and enhanced material flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the antiperspirant pad is made flat and folded along a straight line, then it remains flat and does not bulge, but it cannot properly conform to the curved shape of the garment sleeve
Solution Approach 1:
The patent applies curvature to the fold line itself, transforming it from a straight line to a curved line that matches the garment's sleeve contour. This allows the flat pad to be folded along a curved path, enabling it to conform to the curved shape of the sleeve while maintaining its flat structure without bulging.
Solution Approach 2:
The patent introduces a third dimension by creating a three-dimensional folded structure through curved fold lines. Instead of simply folding a two-dimensional flat pad along a straight line, the curved fold line creates a volumetric form that can accommodate the curvature of the garment sleeve, transitioning from 2D to 3D space.
2Shape
If the antiperspirant pad is folded to match the sleeve curvature, then it can conform to the garment shape, but the material tension causes tearing or unwanted creases
Solution Approach 1:
By curving the fold line to match the desired sleeve contour, the patent distributes material tension evenly along the curved path rather than concentrating it at sharp angles. This curvature allows the material to flex naturally along the fold, preventing tearing and unwanted creases while maintaining structural integrity.
Solution Approach 2:
The patent changes the geometric parameter of the fold line from straight to curved, which fundamentally alters how stress is distributed through the material. The curved geometry allows for gradual bending rather than sharp folds, reducing peak stresses and preventing material failure.
3Area of stationary object
If the antiperspirant pad is made bulky to ensure coverage, then it provides adequate protection, but it becomes annoying and uncomfortable in the armpit
Solution Approach 1:
The curved fold line creates a compact three-dimensional form that provides adequate coverage area while minimizing bulk. The curvature allows the pad to conform to the body's natural contours, distributing the coverage efficiently in three-dimensional space rather than requiring excessive flat material area.
Solution Approach 2:
By folding the pad along curved lines to create a three-dimensional structure, the patent achieves adequate coverage volume without increasing the planar footprint or bulk. The 3D folded configuration allows the pad to fit into the limited space of the armpit while maintaining sufficient coverage area.
