Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clasps and straps offer limited adjustability, often requiring complex mechanisms or coarse adjustments that fail to provide a secure and comfortable fit over time.
Innovation Solution
A clasp assembly comprising a chape with a threaded connector and a clasp component, allowing for easy length adjustment by rotating the components together or apart to achieve precise fit adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed regular spacing of holes in a strap is used, then the clasp operation is simple, but the length adjustment is limited to coarse adjustments only
Solution Approach 1:
The patent transforms the static hole spacing system into a dynamic adjustable system. The threaded connector allows the clasp component to move along the strap, enabling continuous length adjustment rather than fixed coarse adjustments. This dynamic mechanism provides both simplicity in operation and precision in adjustment.
Solution Approach 2:
The patent changes the parameter of strap length adjustability from discrete hole spacing to continuous adjustment. By introducing a threaded connector that allows the clasp component to move along the strap, the system enables fine-tuned length adjustment while maintaining operational simplicity.
2Adaptability or versatility
If a specialized buckle or belt construction is used to provide length adjustment, then the length adjustment capability is improved, but the device complexity increases
Solution Approach 1:
The threaded connector serves multiple functions: it provides length adjustment, acts as a fastening mechanism, and can be integrated with various clasp types (buckles, fold-over clasps, etc.). This universal component reduces overall device complexity while maintaining length adjustment capability.
Solution Approach 2:
The patent merges the length adjustment mechanism with the existing clasp and strap components. The threaded connector is integrated into the clasp assembly, combining adjustment functionality with the fastening mechanism, thereby avoiding additional complex separate adjustment devices.
3Adaptability or versatility
If link removal is used to adjust wristwatch strap length, then the adjustment is possible, but the adjustment precision is insufficient for proper fit
Solution Approach 1:
The patent introduces a dynamic adjustment mechanism where the clasp component can move continuously along the strap via the threaded connector. This allows precise control over the strap length, enabling accurate fit adjustment rather than coarse link removal adjustments.
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
Provides simple and adaptable length adjustment for various clasp and strap types, ensuring a secure and comfortable fit without complex mechanisms.
Implementation Method 1
The threaded connectors may consist of a matching set of an externally threaded cylindrical rod and a component with an internally threaded cylindrical hole. A length adjustment is achieved by rotating the clasp component relative to the chape, thereby threading them together or apart

AI summary
A clasp assembly that provides a length adjustment mechanism. The clasp assembly is constructed from two components that can be threaded together or apart from each other in order to adjust the length of the clasp assembly. A first component attaches to the first end of a strap, and has a threaded connector for attaching to a second component. The second component includes at least one clasp component to facilitate fastening to the second end of the strap, and has a threaded connector that mates with the first component's threaded connector counterpart. A length adjustment is achieved by rotating the second component relative to the first component to thread them together or apart. Changing the distance between the two components allows adjustment of the fastened length of the clasp assembly and strap for an improved fit.
