Curved Clasp with Raised Structures for Adjustable Bracelets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable bracelets with clasps often become disconnected or damaged due to accidental contact with objects, leading to potential loss, and can be difficult to close with one hand.
Innovation Solution
A bracelet design featuring a curved clasp portion with raised structures and a hook portion that follows the band's curvature, along with a cover that secures the clasp and includes magnetic fixation and removable inserts for enhanced engagement and visibility concealment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional clasp design is used, then the bracelet can be adjusted to different sizes, but the clasp becomes disconnected easily when the wearer bangs into something or when the clasp becomes hooked onto something
Solution Approach 1:
The clasp portion is curved to follow the curvature of the band portion, allowing it to conform to the wrist shape and reducing the likelihood of accidental disconnection. The curved design enables the clasp to maintain better contact with the band while accommodating natural wrist movements without compromising the adjustable sizing capability.
2Device complexity
If a traditional clasp design is used, then the bracelet structure is simple, but the clasp can become damaged or bent, sometimes irreversibly
Solution Approach 1:
The curved clasp portion follows the natural curvature of the wrist and band, distributing mechanical stresses more evenly along its length. This curvature design prevents stress concentration at sharp corners or joints, significantly reducing the risk of bending or irreversible damage while maintaining structural integrity.
Solution Approach 2:
The curved geometry of the clasp portion acts as a built-in stress absorber, cushioning against impact forces before they can cause damage. The curved shape allows for gradual deformation under stress rather than sudden failure, providing inherent protection against accidental damage.
3Ease of manufacture
If a traditional clasp design is used, then the manufacturing process is simple, but the clasp closure can take several attempts by the wearer using a free hand to close the clasp
Solution Approach 1:
The curved clasp portion naturally guides the hook along the curvature path during closure, making it easier for the wearer to align and engage the clasp components. The curved design provides a more intuitive closing motion that follows the natural contour of the wrist, reducing the number of attempts needed to successfully close the clasp.
4Ease of manufacture
If the clasp portion is straight, then the manufacturing is simpler, but the gap between the clasp and band is larger
Solution Approach 1:
The curved clasp portion is designed to follow the curvature of the band and wrist, eliminating gaps that would exist with a straight clasp design. This curvature ensures continuous contact between the clasp and band along the wrist contour, providing a more secure fit and better aesthetic appearance while remaining manufacturable.
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 design reduces the likelihood of clasp disconnection and damage, provides easier closure, and maintains a secure fit by minimizing the gap between the clasp and band, while allowing for adjustable sizing and aesthetic customization.
Implementation Method 1
The bracelet can further include magnets positioned to magnetically fix the cover and the clasp portion together.

AI summary
A bracelet having an adjustable clasp portion. The bracelet includes a clasp portion defining a first end, a hook portion having a hook defining a second end, and a band portion between the clasp portion and the hook portion. The clasp portion has raised structures separated by openings and is curved to follow a curvature of the band portion. Each of the raised structures extends laterally relative to the band portion and protrudes beyond an outer surface of the band portion to be engaged by the hook.
