Solution Overview
Problem
Standard fasteners used in extreme applications and for individuals with disabilities are often unreliable, prone to jamming, and difficult to use, lacking durability and ease of operation.
Innovation Solution
A twist-lock fastening system that includes a handle with a grip portion, a negative with an attachment mechanism, and a locking portion that mates with the handle, providing a secure and easy-to-use attachment mechanism through a twist-lock mechanism, which can be magnetic or use other attachment methods, suitable for various abilities and conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard fasteners (snaps, buttons, zippers, hook-and-loop) are used, then they are easy to manufacture and simple in structure, but they are unreliable, prone to jamming, and difficult to use in extreme conditions
Solution Approach 1:
The fastening system is divided into separate components: a first portion that attaches to the button hole and a second portion that attaches to the button. These portions can be detached and reattached through a twist-lock mechanism, allowing for reliable fastening while maintaining simplicity in each individual component.
Solution Approach 2:
The patent replaces traditional mechanical fastening mechanisms (snaps, zippers, hooks) with a twist-lock mechanism that uses rotational motion to create a secure connection. This substitution eliminates jamming issues and improves reliability while keeping the overall structure simple.
2Ease of operation
If standard fasteners are used, then they have simple structure and are easy to manufacture, but they are difficult to manipulate for people with difficulty with fine motor skills
Solution Approach 1:
The twist-lock mechanism transforms the fastening operation from a complex multi-step process to a simple rotational motion. The dynamic twist-lock action provides clear tactile feedback and requires minimal fine motor skill, making it accessible to people with disabilities while maintaining operational simplicity.
3Duration of action of stationary object
If standard fasteners are used, then they are simple in design, but they wear out over time and lack durability
Solution Approach 1:
The first portion and second portion are pre-configured with attachment mechanisms that allow for secure connection to buttons and button holes. This preliminary preparation ensures durable fastening from the outset while keeping the construction simple and easy to manufacture.

AI summary
Various embodiments of a fastening system that either attaches to existing buttons or attaches directly to an article of clothing. In preferred embodiments, the fastening system has a first portion that attaches to a button hole or a first part of the article and a second portion that attaches to a button or second part of the article. The first portion and second portion detachably attach to each other by means of a twist-lock, magnetic mechanism, or some other attachment mechanism. Alternatively, the fastening system can be built directly into an article without augmenting an existing button and button-hole fastener.
