Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ventilation mechanisms for the buttocks focus on centralized ventilation, neglecting the ventilation restriction caused by the crack overlap, leading to increased manufacturing costs and discomfort, particularly for individuals with varying physical characteristics.
Innovation Solution
A ventilation frame composed of elastic material with an elliptical and linear frame configuration, designed to gently arc over the buttocks, featuring elongated holes and a fiber outer shell to minimize irritation and maximize ventilation, while being adaptable to different body shapes and reducing production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a triangular mesh cloth is stitched to form a vent at a specific position, then centralized ventilation of a specific part is achieved, but the ventilation restriction caused by overlapping the crack of buttocks is not considered and manufacturing cost increases
Solution Approach 1:
The patent extracts the ventilation function from the traditional stitched mesh cloth approach and implements it through a separate insertion-type ventilation device with elastic material and frame structure. This allows the ventilation component to be independently manufactured and inserted into underwear, reducing manufacturing complexity and cost while maintaining effective ventilation through the crack of buttocks region
Solution Approach 2:
The ventilation device is segmented into distinct components including a frame structure, elastic material, and ventilation openings, allowing each part to be optimized independently. The frame provides structural support while the elastic material provides flexibility and ventilation, resolving the contradiction between manufacturing simplicity and ventilation reliability
2Object-affected harmful factors
If a protrusion is formed on the main body to make the center protrude, then the structure provides support, but it produces unexpected side effects due to irritation of the protrusion
Solution Approach 1:
The patent replaces sharp protrusions with curved, rounded surfaces on the frame structure and elastic material. The frame has rounded corners and the elastic material forms a smooth, contoured surface that adapts to body shape without creating irritating pressure points, while still providing necessary structural support through the curved geometry
Solution Approach 2:
The patent uses flexible elastic material as the main body covering that conforms to body contours without creating rigid protrusions. This flexible shell provides structural support through its elasticity and tension while avoiding local irritation by distributing pressure evenly across the surface without sharp edges or rigid protruding elements
3Adaptability or versatility
If the ventilation frame is made of elastic material with elliptical and linear frame configuration, then deformability and comfort are improved, but device complexity increases
Solution Approach 1:
The patent designs a universal frame structure with elliptical and linear elements that can adapt to various body shapes and sizes. The elastic material and flexible frame configuration allow the same device design to accommodate different users without requiring multiple size variants, achieving versatility without proportionally increasing complexity
Solution Approach 2:
The patent combines the elliptical frame elements and linear connecting elements into an integrated structure where the same elastic material serves multiple functions: providing structural support, enabling deformation, and creating ventilation openings. This merging of functions reduces the number of separate components needed, balancing adaptability with manufacturing simplicity
