Undergarment Band Length Altering Device for Expanded Girth Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing undergarment adjustable fastening systems often fail to provide an expanded range of girth adjustment, leading to a suboptimal fit due to factors like weight changes or material stretching/shrinking, necessitating the purchase of a new garment or limited adjustment beyond the original range.
Innovation Solution
A device with elongated body and band retaining loops at each end, featuring offset fastening elements (hooks and eyes) that can be retrofitted to undergarments to increase or decrease girth beyond the original adjustment range, allowing for additional girth adjustment by repositioning the attachment points of the back bands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional hook and eye fastening system is used, then the undergarment provides basic adjustability within a fixed range, but the adjustment range is limited and cannot be expanded beyond the original design
Solution Approach 1:
The patent introduces an intermediary device (the band length altering device with elongated body and fastening elements) that mediates between the first and second bands. This intermediary component extends the adjustment range by providing additional attachment points without requiring a complete redesign of the original fastening system, thus resolving the contradiction between expanded adaptability and device complexity.
Solution Approach 2:
The invention segments the adjustment function by separating the original hook-and-eye system from the band structure and introducing a distinct altering device. This segmentation allows the adjustment range to be expanded independently while keeping the original fastening mechanism intact, thereby increasing adaptability without proportionally increasing overall system complexity.
2Adaptability or versatility
If the undergarment is purchased in a larger size to accommodate future weight gain, then the garment can fit larger sizes, but it will fit poorly when the wearer is at a smaller size
Solution Approach 1:
The patent implements a dynamic adjustment system where the band length can be modified in real-time based on the wearer's needs. The altering device allows the user to dynamically change the girth by repositioning bands along the elongated body, enabling the undergarment to adapt to different body sizes and weight fluctuations, thus resolving the contradiction between size accommodation and fit optimization.
3Ease of operation
If multiple undergarments are purchased to cover different size needs, then each garment provides ideal fit for specific sizes, but it increases cost and wardrobe complexity
Solution Approach 1:
The band length altering device serves multiple functions: it can extend the band length for weight gain, reduce it for weight loss, and provide intermediate adjustments. This multi-functionality allows a single undergarment to replace multiple garments of different sizes, thereby reducing the quantity of garments needed while maintaining fit quality across different body measurements.

AI summary
A device for altering the length of an undergarment band assembly includes an elongated body having a first band retaining loop arranged at a first end of the body, and a second band retaining loop arranged at a second end of the body. A first fastening element is arranged proximate the first end of the body and is configured to engage with a second band fastener of a second band of the undergarment band assembly. A second fastening element is arranged proximate the second end of the body and is configured to engage with a first band fastener of a first band of the undergarment band assembly.
