Adjustable Bracelet Knot Structure for Secure Wrist Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing jewelry bracelets have unattractive and difficult-to-secure associating means that are prone to loosening and slipping off the wrist, failing to accommodate different wrist sizes effectively.
Innovation Solution
A method and design for creating a jewelry bracelet using handwoven leather straps with glass seed beads and gemstones, featuring adjustable sizing through knots and a center ring mechanism, with bead mounting threads securing the beads within a bracelet cavity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional fasteners, clasps, or clips are used to connect strap ends, then the bracelet can be assembled, but the associating means become unattractive, hard to secure with one hand, and prone to loosening
Solution Approach 1:
The bracelet uses a self-securing knot system where the strap ends are tied together in a manner that automatically locks in place when worn. The knots are designed to tighten naturally around the wrist without requiring additional fasteners or complex securing mechanisms, allowing the bracelet to secure itself through the act of wearing it.
Solution Approach 2:
The bracelet is divided into multiple segments including the strap, decorative elements, and knot connections. This segmentation allows each component to be optimized independently, with the knot sections providing secure attachment points that are both aesthetically pleasing and functionally reliable, avoiding the need for separate fastening mechanisms.
2Adaptability or versatility
If traditional associating means are used, then the bracelet can be fastened, but they are not able to be configured for different sized wrists
Solution Approach 1:
The bracelet incorporates adjustable knots that can be repositioned along the strap to accommodate different wrist circumferences. The knot system is designed to be dynamic rather than fixed, allowing the wearer to adjust the positioning and tightening of knots to fit various wrist sizes without requiring multiple different bracelet designs or complex adjustment mechanisms.
3Reliability
If traditional associating means are used, then the bracelet can be connected, but they loosen fairly easily allowing the bracelet to fall or slip off
Solution Approach 1:
The knot system is designed with inherent anti-loosening properties that prevent the bracelet from slipping off the wrist. The knots are tied in a manner that creates natural resistance to loosening through the weight and movement of the bracelet itself, counteracting the tendency of traditional associations to loosen over time without requiring additional securing mechanisms.

AI summary
A jewelry bracelet includes a first strap having a first strap first end, a first strap second end and a first strap length, a second strap having a second strap first end, a second strap second end and a second strap length, wherein the first strap first end is tied to the second strap along the second strap length and the second strap first end is tied to the first strap along the first strap length to define a bracelet cavity, a plurality of bead lines, wherein the plurality of bead lines are associated with the first strap and the second strap via a mounting thread to be securely and tightly disposed within the bracelet cavity and a center ring defining a center ring cavity, wherein the first strap second end and the second strap second end are securely associated with the center ring to define a wrist cavity.
