Flexible Plastic Bra Fastener with D-Shaped Hook
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fasteners for brassieres, such as hook and eye fasteners, cause discomfort due to their bulkiness and rigidity, are difficult to use, and can damage the garment or washing machine during washing, while existing plastic alternatives are aesthetically unattractive and lack flexibility.
Innovation Solution
A low-profile, flexible fastener system comprising a rigid first component with a D-shaped engagement portion and a flexible second component with slotted apertures, where the first component is secured to the garment strap via stitching and the second component is made from a bendable polyester substrate with a roughened surface, allowing easy use and improved comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If metal hook and eye fasteners are used, then the fastening function is achieved, but discomfort is caused due to bulkiness and rigidity
Solution Approach 1:
The patent applies this principle by using a thin, flexible plastic plate instead of rigid metal hooks and eyes. The fastening components are made from flexible material that can conform to body contours, eliminating the bulkiness and rigidity that cause discomfort while maintaining the fastening function.
Solution Approach 2:
The patent changes the physical parameters of the fastening components by transitioning from metal to flexible plastic material. This parameter change allows the fastener to be thinner, more flexible, and comfortable against the skin while still providing adequate fastening strength.
2Ease of operation
If metal hook and eye fasteners are used, then the fastening function is achieved, but difficulty in fastening occurs
Solution Approach 1:
The patent applies this principle by designing a fastening system where the flexible plastic components automatically conform to each other when brought together. The elasticity and flexibility of the material enable self-alignment and self-fastening, reducing the complexity of the fastening mechanism and making it easier for users to operate.
3Reliability
If metal hook and eye fasteners are used, then the fastening function is achieved, but damage occurs during washing
Solution Approach 1:
The patent applies this principle by using flexible plastic fastening components that are inexpensive to manufacture and replace. These components are designed to withstand repeated washing cycles without causing damage to the garment or washing machine, and can be easily replaced if worn, maintaining reliability while eliminating harmful effects.
Solution Approach 2:
The patent uses flexible plastic material that combines the benefits of durability with softness. This composite approach creates a fastening system that is both reliable for repeated use and gentle enough to prevent damage during washing, unlike rigid metal components.
4Ease of operation
If plastic fasteners are used to replace metal hooks and eyes, then comfort is improved, but aesthetic appearance deteriorates
Solution Approach 1:
The patent applies this principle by using a thin, flexible plastic plate that can be made in various colors and finishes. The thin profile and flexibility allow it to conform to body shapes and can be aesthetically pleasing, while the material can be selected to match or complement the garment design.
