Bead Securement Spring with Detachable Covers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing beads on a string, such as those using coiled springs, cause user discomfort due to concentrated force on thin end members and lack sufficient traction, leading to beads sliding off and requiring permanent solutions that affect the aesthetic and functional quality of jewelry.
Innovation Solution
A device comprising a tension spring with detachable end covers that distribute force over a wider surface area and provide textured traction, allowing easy securement and removal of beads by deforming the spring to hold the filament in place between its coils.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If coiled spring end members are used to secure beads, then the securement function is achieved, but user discomfort occurs due to concentrated force on thin end members
Solution Approach 1:
The end member is segmented into two distinct components: the thin-walled collapsible body and the separate cap. This segmentation allows the cap to serve as a force-distributing interface while the collapsible body maintains its sealing function, resolving the contradiction between securement effectiveness and user comfort.
Solution Approach 2:
The cap acts as an intermediary element between the user's finger and the collapsible body. It mediates the force application by distributing it across a larger surface area, preventing the concentrated force that causes discomfort while still enabling effective compression of the collapsible body.
2Ease of operation
If coiled spring end members are used to secure beads, then the securement function is achieved, but traction and grip are insufficient
Solution Approach 1:
The cap is designed with locally optimized properties including textured or ribbed surfaces that provide enhanced grip. This local quality improvement at the contact point with the user's finger solves the traction problem without affecting the overall structural integrity or securement strength.
3Reliability
If permanent solutions like knots or glued beads are used, then beads are securely held, but aesthetic and functional characteristics are adversely affected
Solution Approach 1:
The end member transitions from a static structure to a dynamic collapsible body that can be compressed and expanded. This dynamic behavior enables reversible securement - the beads are held firmly during normal use, but can be easily released by compressing the body, maintaining both reliability and aesthetic integrity.
Solution Approach 2:
The collapsible body can be temporarily deformed (compressed) to release the beads when needed, then recovered to its original shape to重新 secure them. This reversible process allows the user to discard the temporary deformation state and recover the original aesthetic state, avoiding permanent modifications.
4Device complexity
If thin end members are used in coiled springs, then the spring structure is maintained, but substantial concentration of force is exerted on user's fingertips
Solution Approach 1:
The end member is segmented into two distinct components: the thin-walled collapsible body and the separate cap. This segmentation allows the cap to serve as a force-distributing interface while the collapsible body maintains its sealing function, resolving the contradiction between securement effectiveness and user comfort.
Solution Approach 2:
The cap acts as an intermediary element between the user's finger and the collapsible body. It mediates the force application by distributing it across a larger surface area, preventing the concentrated force that causes discomfort while still enabling effective compression of the collapsible body.
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 device effectively secures beads without user discomfort and allows for easy removal, preventing beads from sliding off while maintaining the aesthetic and functional integrity of the jewelry.
Implementation Method 1
force is translated to the spring by way of force exerted on the covers. Such forces cause the spring to deform and the gaps between the plurality of coils on the spring to expand

AI summary
The present invention is directed toward a bead securement device comprising a tension spring, a first cover and a second cover. The first cover and the second cover are removably secured to the tension spring. In use, a force is exerted on the spring through the covers causing the spring to deform and the gaps between the plurality of coils on the spring expand. Once expanded, the filament may be passed in between one of these gaps so that when the force exerted on the end members of the spring is released, the filament is squeezed between the coils of the spring and held in place. The filament can be easily removed by using the covers to manipulate the end members of the spring.
