Elastic Bracelet Bezel Structure That Hides the Stretch Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing extensible bracelets with elastic members have poor aesthetic quality due to the elastic member being visible when enlarged, and there is a risk of bezels slipping out if the elastic member breaks.
Innovation Solution
A wearable decorative element with a design that includes bezels and male elements with complementary shapes and a block element to cover the elastic member, ensuring it remains hidden even in enlarged configurations, and prevents bezels from slipping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bracelet is enlarged to allow it to be worn, then the elastic member is loaded and the bezels are spaced apart from each other, but the elastic member becomes visible giving the bracelet poor aesthetic quality
Solution Approach 1:
A covering element is introduced as an intermediary component between the elastic member and the external environment. This covering element has a first portion that covers the elastic member when the bracelet is in the worn configuration, and a second portion that allows the elastic member to pass through when the bracelet is in the stored configuration, thus resolving the contradiction between ease of wearing and aesthetic quality.
2Reliability
If the elastic member breaks, then the bezels slide out of it, but this increases the risk of losing the bezels
Solution Approach 1:
The covering element serves as a protective barrier that prevents the harmful consequence of elastic member breakage. By covering the elastic member and extending into the bezel cavity, it provides a physical constraint that prevents bezels from sliding out even if the elastic member breaks, thus beforehand cushioning against the risk of losing bezels.
3Shape
If a covering element is added to hide the elastic member, then aesthetic quality improves, but device complexity increases
Solution Approach 1:
The covering element is designed to perform multiple functions simultaneously: it covers the elastic member to improve aesthetics, allows the elastic member to pass through for storage and retrieval, and prevents bezel loss in case of breakage. By making the covering element multi-functional, the patent improves aesthetic quality without proportionally increasing device complexity.
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 enhances the aesthetic value by hiding the elastic member and prevents bezel loss, providing a simple, rational, and effective solution with reduced components.
Implementation Method 1
The elastic member 2 may be, e.g., a mechanical spring, preferably a cylindrical helix spring, or an element of elastic material, so that when subjected to a tension, the bracelet 1 undergoes an elastic deformation switching from a home configuration to an enlarged one.

AI summary
The wearable decorative element (1) comprises at least one ring-shaped elastic member (2), supporting a plurality of female elements (3), wherein each of the female elements (3) comprises a hollow body (30) extended between a first and a second through opening (32, 33) obtained between two lateral walls (34, 35) opposite each other for the passage and sliding of the elastic member (2), a plurality of male elements (4) adapted to allow the passage and sliding of the elastic member (2) therein, each of the male elements (4) inserting in a sliding manner at least partly inside one of the first through opening (32) and the second through opening (33) of one of the adjacent female elements (3) to vary the mutual distance between the female elements (3a, 3b) along a direction of sliding (S), wherein it comprises at least one block element (5) associated with one of either the female element (3) or the male element (4) transversely with respect to the direction of sliding (S) to limit the mutual sliding between the female elements (3) on the male elements (4) and to cover the elastic member when the distance between the adjacent female elements is maximum.
