Vacuum Canula for Gemstone Vertical Alignment in Glass
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for encasing gemstones in glass, such as diamonds, often result in varying product quality and high waste due to random positioning and voids, as gems are not accurately aligned vertically within the glass tube during the melting process.
Innovation Solution
A vacuum tweezer technique using a canula with a heat-resistant guiding mechanism and an end piece embossed with the gemstone's shape ensures precise vertical placement, combined with heat-resistant materials like PTFE clips or spirals to maintain alignment during the glass encasing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If gems are randomly dropped into a glass tube, then the process is simple and fast, but the positioning precision and product quality become poor with high waste
Solution Approach 1:
The patent introduces a canula as an intermediary tool between the gemstone and the glass tube. The canula with its negative impression cavity precisely positions the gemstone vertically before insertion into the glass tube, mediating the transfer from random dropping to precise positioning without complicating the overall process
Solution Approach 2:
The canula is pre-formed with a negative impression of the gemstone shape at its tip, creating a preliminary positioning structure that ensures correct vertical orientation of the gemstone before it is inserted into the glass tube during the melting process
2Productivity
If gems are heated and dropped into half-molten glass tube, then productivity is high, but the optical effect deteriorates due to voids and misalignment
Solution Approach 1:
The canula serves as a mediating device that maintains high productivity by enabling quick insertion while simultaneously ensuring precise vertical alignment of the gemstone through its specially designed tip with negative impression, preventing voids and misalignment issues
3Manufacturing precision
If tweezers or forceps are used to inject gems, then positioning control improves, but the device complexity and operation difficulty increase
Solution Approach 1:
The canula replaces complex tweezers or forceps as an intermediary placement tool. It achieves precise vertical positioning through its simple cylindrical structure with a pre-formed negative impression at the tip, reducing device complexity while maintaining high placement accuracy
Solution Approach 2:
The canula's tip is designed with a negative impression that changes the geometric parameters of the placement interface, creating a precise fit for the gemstone that ensures correct vertical orientation without requiring complex mechanical adjustments or operations

AI summary
For positioning gemstones, that need to be encased into glass exactly for to achieve maxi¬ mum optical effect, a suction canula is applied, having an opening to fit the gemstone and elements like spirals or meshes to provide even distance from the walls of the glass tube it is inserted in.
