Earring Post Integral Cup and Hollow Passage Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional earring post constructions require separate attachment means, such as staking and soldering, which can be cumbersome and inefficient, especially when using precious metals.
Innovation Solution
An elongated earring post and cup are integrally formed in a single piece, eliminating the need for attachment means and incorporating a securing stud and an elongated passage to minimize precious metal usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate attachment means (staking and soldering) are used to secure the post with the cup, then the connection between post and cup is achieved, but the manufacturing process becomes cumbersome and inefficient
Solution Approach 1:
The post and cup are merged into a single integral piece through one-step forming, eliminating the need for separate attachment operations like staking and soldering. This combining of previously separate components directly resolves the contradiction by simplifying the manufacturing process while reducing overall structural complexity.
Solution Approach 2:
The integral post-cup structure is segmented to include an elongated passage running through the post, which reduces material usage while maintaining structural integrity. This segmentation approach allows the single-piece construction to achieve both manufacturing simplicity and reduced complexity through strategic material placement.
2Productivity
If the post and cup are constructed as separate pieces requiring attachment means, then the structural integrity can be maintained, but the manufacturing time and process complexity increase
Solution Approach 1:
The post and cup are pre-formed as a single integrated structure through one-step forming, eliminating the need for subsequent attachment operations. This preliminary integration of components directly improves productivity by completing the structural formation in one operation while reducing the time loss associated with multiple manufacturing steps.
3Quantity of substance
If solid precious metal is used for the entire post construction, then the strength and elegance are ensured, but the amount of precious metal consumption increases
Solution Approach 1:
The post incorporates an elongated passage creating a hollow or porous structure within the solid precious metal. This allows significant reduction in the quantity of precious metal required while maintaining sufficient strength for earring application, as the passage reduces material consumption without compromising the structural integrity needed for the decorative piece support.
4Reliability
If multiple attachment means are used to secure the post with the cup, then the connection reliability is improved, but the manufacturing complexity and precious metal usage increase
Solution Approach 1:
The post and cup are merged into a single integral piece through one-step forming, which inherently provides reliable connection without requiring additional attachment means. This merging eliminates device complexity associated with multiple attachment methods while maintaining or improving connection reliability through the unified structure.
