Innovation Solution
A Y-shaped binding tape with unequal leg lengths and a non-split portion, allowing for seamless integration with garments and eliminating complex doubling steps, made from elastic textile material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional binding tapes are used with doubling operations, then the binding tape provides sufficient strength and stability, but the production process becomes complex and time-consuming
Solution Approach 1:
The binding tape is divided into two distinct legs of unequal lengths extending from a central attachment line. This segmentation allows the binding tape to function without complex doubling operations, simplifying the production process while maintaining structural integrity. The first leg (longer) and second leg (shorter) can be independently positioned and secured.
Solution Approach 2:
The binding tape employs asymmetric design with legs of different lengths (first leg longer than second leg). This asymmetry eliminates the need for symmetric doubling operations, reducing production complexity. The unequal leg lengths provide functional differentiation while simplifying the manufacturing process compared to traditional symmetric doubled binding tapes.
2Ease of operation
If traditional doubled binding tapes are used, then the binding tape provides adequate coverage, but it creates creases that prevent seamless wear against the body
Solution Approach 1:
Instead of folding the binding tape back on itself (doubling), the invention inverts the approach by extending two legs in opposite directions from a central attachment line. This eliminates the creases and folds inherent in traditional doubled binding tapes, providing a smooth surface that can wear seamlessly against the body.
Solution Approach 2:
The binding tape transitions from a one-dimensional folded structure to a two-dimensional configuration with legs extending in different directions from the attachment line. This dimensional change eliminates the need for folding, thereby removing creases and enabling seamless wear against the skin.
3Productivity
If unequal leg lengths are used in the binding tape, then the binding tape can be easily inserted and secured, but the structural symmetry is compromised
Solution Approach 1:
The binding tape deliberately employs asymmetric leg lengths to improve garment assembly efficiency. The unequal lengths (first leg longer than second leg) allow for easier insertion and securing of the garment edge, while the asymmetric design itself becomes the functional feature rather than a deviation from symmetry.
