Gemstone Garment Snap Assembly Using Thermal Expansion Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing garment snaps lack the incorporation of gemstones and crystals as decorative elements, despite advancements in materials and manufacturing techniques.
Innovation Solution
The process involves cutting stones with a Rockwell hardness of 7 to 10 into hemispherical shapes, setting them into button casings, applying heat to secure the casing, and adding a protective enamel finish to create gemstone snaps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If gemstones and crystals are incorporated into garment snaps, then the aesthetic appeal and ornamental value of the snaps is enhanced, but the manufacturing complexity and difficulty increases due to the hardness of the stones (Rockwell hardness 7-10)
Solution Approach 1:
The snap fastener is divided into separate components: a button portion with the gemstone embedded and a separate snap portion. This segmentation allows the gemstone to be set into the button portion independently, simplifying the overall manufacturing process while maintaining the aesthetic appeal of the complete snap assembly.
Solution Approach 2:
The gemstone is cut into a hemisphere shape and set into the button portion before the snap mechanism is attached. This preliminary preparation of the gemstone and button assembly makes the subsequent attachment of the snap mechanism easier and more manageable, reducing the overall manufacturing difficulty.
2Manufacturing precision
If gemstones are cut into hemispherical shapes, then the decorative quality of the snaps is improved, but the time and patience required for manufacturing increases significantly
Solution Approach 1:
The gemstones are pre-cut into hemispherical shapes before being set into the button portions. This preliminary preparation allows for precise shaping to be done in advance, enabling the main assembly process to proceed more quickly and efficiently without sacrificing the decorative quality of the gemstone settings.
Solution Approach 2:
Multiple gemstones of the same type and cut can be produced using standardized cutting techniques and templates, allowing for replication of the precise hemispherical shape across multiple snaps. This reduces the time required for each individual gemstone while maintaining consistent manufacturing precision.
3Reliability
If heat is applied to fit the stone into the casing, then the stone is securely fixed in the button, but the risk of damaging the stone or surrounding materials increases
Solution Approach 1:
The button portion material is selected to have specific thermal properties that allow it to expand temporarily when heated, creating space for the gemstone to be inserted. After cooling, the material contracts and secures the gemstone firmly. By controlling the temperature parameters within a safe range, the fixation is achieved without damaging the gemstone or surrounding materials.
Solution Approach 2:
The button material undergoes a thermal expansion and contraction phase transition to facilitate gemstone insertion and secure fixation. When heated, the material expands to allow the gemstone to be positioned; when cooled, it contracts to firmly hold the gemstone in place, providing reliable fixation without requiring excessive heat that could cause damage.

AI summary
A snap and a method for making a snap using on articles of clothing where an ornamental crystal or gem stone occupies a visible portion of the snap. To construct the snap, a housing is provided that is adapted to receive a shaped ornamental substrate only after thermally expanding the substrate, and the snap can then be used on articles of clothing to enhance the appearance of the clothing.
