Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional earring structures are prone to entanglement, damage, and loss of attractiveness due to a single-point pivot attachment, which leads to premature failure and reduced value, as they fail to maintain a common plane of motion and are susceptible to hair and other jewelry entanglement.
Innovation Solution
A jewelry support system with an inner and outer pivot member arrangement featuring clasp assemblies and tapered contact surfaces, allowing the outer jewelry member to pivot along a common plane, enhancing reliability and decorative appeal by providing a dual-point contact during motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single-point pivot attachment is used in conventional earring structures, then the structure is simple and easy to manufacture, but it is prone to entanglement, damage, and premature failure
Solution Approach 1:
The single pivot point is segmented into multiple pivot points (at least two pivot points) distributed along an arc path. This segmentation distributes the mechanical stress and motion forces across multiple contact points, preventing premature failure and entanglement while maintaining a relatively simple overall structure.
Solution Approach 2:
The pivot attachment transitions from a single-point (0D) attachment to a multi-point arc-based attachment that operates in a curved path. This dimensional change from point to arc allows the jewelry item to pivot smoothly along a defined arc while maintaining consistent indicia presentation, reducing entanglement and damage risks.
2Shape
If a single-point pivot arrangement is used, then the manufacturing is simple, but the earring fails to maintain a common plane of indicia display
Solution Approach 1:
The pivot attachment uses a dynamic arc-based mechanism where the jewelry item pivots along a predetermined arc path between the inner and outer pivot members. This dynamic motion ensures that the indicia on the outer member remains presented in a common plane relative to the inner member throughout the range of motion, while the tapered contact surfaces facilitate smooth pivoting.
Solution Approach 2:
The invention changes the geometric parameters of the pivot attachment by introducing tapered contact surfaces on the pivot members. These tapered surfaces (with angles of 15-45 degrees) enable the jewelry item to pivot smoothly along the arc while maintaining the common plane of indicia display, achieving the desired shape maintenance with manageable manufacturing complexity.
3Strength
If a single-point pendulum action is used, then the structure is simple, but the pivot attachment is weak and prone to premature failure
Solution Approach 1:
The single-point pendulum action is replaced with a multi-point arc-based pivot system. By distributing the pivot function across multiple contact points along an arc path, the mechanical strength and durability of the attachment are significantly improved, preventing premature failure while keeping the structural complexity manageable through the use of tapered contact surfaces.

AI summary
A jewelry support system and method for supporting motion indicia in a jewelry system includes an inner pivot support member and an outer pivot member for an earring. There is a clasp assembly and two outer pivot members extending from the inner side of the outer pivot member positioned along a common pivot plane at two distal pivot locations. There are two inner pivot members that pivotally engage the respective outer pivot members and have tapered contact surfaces so as to provide a single-point contact at each location during a pivot motion so that an enhanced decorative pivot system is achieved with improved reliability.
