Coaxial Container Elastic Latch Concentricity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coaxial containers for dispensing tubular products face issues such as incomplete support from positioning pieces, poor concentricity due to uniform material ribs, and inadequate resistance, leading to assembly challenges and operational inefficiencies.
Innovation Solution
A coaxial container design featuring an inner tube connected to a rotating base with elastic latches arranged in a full circle, where each latch has a harder thicker portion and a softer thinner portion, providing enhanced resistance and concentricity through a spiral groove mechanism, eliminating the need for lubrication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If positioning pieces or uniform ribs are used for support, then the structure is simple, but full circle support and good concentricity cannot be achieved
Solution Approach 1:
The elastic latch is designed with non-uniform cross-sectional area, featuring a thicker first portion and a thinner second portion. This local quality variation creates different resistance forces at different locations, with the thicker portion providing stronger support against the inner tube and the thinner portion allowing flexibility. This resolves the contradiction by achieving full circle support and good concentricity through localized structural differentiation rather than uniform design.
2Force
If fixed structure ribs are used, then manufacturing is simple, but adequate resistance and concentricity cannot be achieved
Solution Approach 1:
The elastic latch replaces fixed rigid ribs with a dynamic flexible structure. The latch can deform elastically under load, allowing it to adapt to the inner tube's position and provide optimal resistance force. This dynamic capability enables adequate resistance and concentricity while maintaining manufacturing simplicity through a single-piece elastic component that can be molded in various cross-sectional shapes.
3Stability of the object's composition
If conventional positioning pieces are used, then the structure is simple, but full circle support cannot be provided causing tilting
Solution Approach 1:
The elastic latch integrates multiple functions into a single component: it provides full circle support around the inner tube, maintains concentricity through its elastic deformation, and prevents tilting by distributing support forces uniformly. This merging of support, positioning, and stabilizing functions into one element achieves rotational stability without requiring multiple separate positioning pieces or complex rib structures.
