Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spinner rings face issues with structural integrity and comfort due to crude fabrication methods, leading to bulkiness and the risk of parts detaching, which compromises their soothing purpose.
Innovation Solution
A 3D printing method that simultaneously materializes two bands with annular channels and protrusions, allowing one band to revolve around the other without fusion, ensuring secure interlinking and preventing separation, thus eliminating the need for bending or fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If crude fabrication methods (hammering, bending, soldering) are used to create spinner rings, then manufacturing simplicity is maintained, but structural integrity deteriorates and parts may detach
Solution Approach 1:
The patent merges the inner and outer bands into a single monolithic structure fabricated by 3D printing. The interlocking features (protrusions and recesses) are integrated into the same continuous material, eliminating the risk of detachment while maintaining manufacturing simplicity through additive manufacturing.
Solution Approach 2:
The patent implements nested interlocking features where the outer band contains recesses that accommodate protrusions from the inner band. This nesting arrangement provides secure mechanical interlocking while allowing the outer band to rotate freely, resolving the contradiction between ease of manufacture and structural integrity.
2Reliability
If band thickness is increased to compensate for compromised structural integrity, then reliability improves, but device bulkiness increases and comfort deteriorates
Solution Approach 1:
By combining both bands into one monolithic structure with internal interlocking features, the patent achieves high structural integrity without increasing external band thickness. The comfort is maintained because the reinforcement is internal rather than external, avoiding bulkiness.
3Adaptability or versatility
If individual bands are fabricated separately and then assembled, then manufacturing flexibility is maintained, but manufacturing precision deteriorates due to large gaps and shaking
Solution Approach 1:
The patent merges the fabrication process into a single 3D printing operation that creates both bands with precise interlocking features in one monolithic structure. This eliminates gaps and shaking issues while maintaining design flexibility through digital modeling and additive manufacturing capabilities.
4Ease of manufacture
If bending or contorting bands during fabrication, then assembly is simplified, but structural integrity deteriorates and design features may be warped
Solution Approach 1:
The patent eliminates the need for bending or contorting by fabricating the entire interlocked structure in one piece using 3D printing. The additive manufacturing process builds the complex interlocking geometry layer by layer without requiring post-fabrication deformation, thus preserving structural integrity and design features.
