Shaping Pants Using Knitted Fabric and Foam Inserts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pants for shaping the female buttocks and hips are limited by their inability to utilize knitted fabrics effectively, as they are considered unsuitable for retaining and shaping anatomical parts due to their yielding nature.
Innovation Solution
Design of pants using knitted fabric with specific elements and inserts made of materials like polyurethane and silicone, which increase the fabric's elastic modulus and tenacity, allowing it to adhere to and shape the buttocks and hips while highlighting their shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If knitted fabric is used for pants, then the fabric is more flexible and comfortable, but it cannot retain and shape the buttocks and hips effectively
Solution Approach 1:
The patent applies composite materials by combining knitted fabric with foam inserts and elastic bands. The knitted fabric provides flexibility and comfort, while the foam inserts and elastic bands provide structural support and shape retention. This composite structure resolves the contradiction by allowing the pants to be made of comfortable knitted material while still achieving the desired shaping effect through the integrated supportive elements.
Solution Approach 2:
The patent applies local quality by placing foam inserts and elastic bands specifically in the buttocks and hips regions where shaping is needed, rather than making the entire pants structure rigid. The knitted fabric is used in areas where flexibility is desired, while the supportive elements are concentrated in the critical shaping zones, thus maintaining overall comfort while achieving localized shape retention.
2Reliability
If body-shaping garments are inserted inside pants, then shaping effect is improved, but the number of components and manufacturing complexity increases
Solution Approach 1:
The patent merges the body-shaping garment functions directly into the pants structure by integrating foam inserts and elastic bands as inherent components of the pants rather than separate insertable garments. The foam inserts are positioned within pockets formed by the pants structure, and the elastic bands are sewn into the pants, creating a unified garment that provides shaping effects without requiring separate body-shaping components.
Solution Approach 2:
The patent creates a composite pants structure where the knitted fabric, foam inserts, and elastic bands are integrated into a single manufacturable product. This composite approach allows the shaping elements to be incorporated during the pants manufacturing process rather than requiring assembly of separate components, thus reducing device complexity while maintaining shaping effectiveness.
3Ease of manufacture
If knitted fabric is used, then industrial manufacturing with conventional fabrics is enabled, but the fabric was traditionally considered unsuitable for shaping
Solution Approach 1:
The patent resolves this contradiction by using knitted fabric as the base material (which is industrially manufacturable and conventional) and combining it with foam inserts and elastic bands to achieve the shaping effect. This allows the pants to be manufactured using standard textile industrial processes for the knitted fabric while the added components provide the previously missing shaping capability.
Solution Approach 2:
The patent changes the physical parameters of the pants structure by introducing foam inserts with specific density and elasticity properties, and elastic bands with controlled tension characteristics. These parameter changes enable the knitted fabric pants to achieve shaping effects that were previously only possible with more rigid materials, thus making conventional knitted fabrics suitable for shaping applications.

AI summary
Pants for shaping the female buttocks and hips including: a first rear part to at least partially cover the buttocks, the first part including: at least one first element to cover at least a lower terminal portion and lateral portion of the buttocks, at least one second element to cover at least a central portion of the buttocks, and at least one third element to cover at least an upper terminal portion of the buttocks. The first, second and third element include a knitted fabric, and the second element includes two parts, each adapted to cover only one of the two central parts of the buttocks. The two parts secured together along respective lateral edges provided at the intergluteal cleft of the buttocks by a central seam adapted to be positioned at the cleft.
