Garment Fastening Element With Internal Padding Seam
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening elements for corsetry straps, such as those in women's undergarments, often cause skin irritation due to sharp edges from manufacturing processes, which can lead to discomfort and irritation, especially when worn directly on the skin.
Innovation Solution
A fastening element design where the padding is attached between the strap plies, with the joining seam positioned internally, allowing the padding to alleviate pressure and the seam to be inaccessible during use, thus preventing skin contact and irritation. This involves turning over the strap plies to position the padding between them, ensuring the seam is not in contact with the skin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the padding is attached to the outer side of the fastening element, then the manufacturing process is simple, but the joining seam rests on the skin and causes irritation
Solution Approach 1:
The patent applies inversion by turning the strap plies over after attaching the padding to the outer side. This reverses the orientation of the fastening element, moving the joining seam from the outer skin-contact surface to the inner non-contact surface, while keeping the padding between the strap plies for comfort.
2Object-affected harmful factors
If the strap plies are turned over to position the padding between them, then the joining seam becomes inaccessible and prevents skin irritation, but the structural complexity increases
Solution Approach 1:
The patent applies nesting by placing the padding between the strap plies, with the joining seam nested within the layered structure. When the strap plies are turned over, the seam becomes hidden within the nested layers, inaccessible to the skin, while the padding remains positioned for comfort.
3Object-affected harmful factors
If the padding is positioned between strap plies with internal joining seam, then comfort is improved, but additional manufacturing operations are required
Solution Approach 1:
The patent applies preliminary action by attaching the padding to the outer side of the fastening element before turning the strap plies over. This preliminary attachment simplifies the manufacturing process, as the padding is secured in its correct position between the strap plies before the final orientation is achieved, avoiding the need for complex internal attachment operations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides improved comfort by creating a flat contact area with the skin and preventing the seam from causing irritation, while also simplifying the manufacturing process and ensuring the padding remains securely in place without additional operations.
Implementation Method 1
the individual eye tapes are separated from the endless base tape by the thermal welding method, for example by an ultrasonic welding method, so that the cut edges of the base tape and the fold tapes are joined to one another at the same time
Implementation Method 2
a padding is provided for increasing the comfort of wear, the padding being applied to at least one of the strap plies by joining it near the lateral edges of the fastening element

AI summary
A fastening element is provided for an end area of a first strap of an item of corsetry, particularly of women's undergarments. The fastening element is to be fastened to a second strap of the item of corsetry and has an number of strap plies of which at least one strap ply has a fastening part such as at least one hook, one eye or the like. Comfort of wear is improved for a fastening element of this type with a padding provided between two strap plies. This padding is attached to at least one of the strap plies by joining it near the lateral edges of the fastening element. When the fastening element is in use, the fastening is located, at least in part, between strap plies of the fastening element.
