Embossed Container Wall Trough for Moisture Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers face challenges in maintaining effective moisture protection, especially when water sprays up from below, as the current designs with recesses and projections may allow moisture ingress through the wall openings if the cover is not fully extended.
Innovation Solution
The container design features a trough formed by deforming the wall material, creating inward projections that serve as recesses without separate components, allowing for a positive locking mechanism between the base and lid while minimizing material usage and weight, and enhancing moisture protection by embossing the wall material to create a cavity between the inner and outer surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cover is pulled down deep to cover the wall openings for moisture protection, then protection against moisture ingress is improved, but the material usage and weight of the container increase
Solution Approach 1:
The trough and hood are merged into a single integrated component that is embossed directly from the wall material, eliminating the need for separate parts. This integration maintains effective moisture protection while reducing the total material required compared to using separate deep extensions of both trough and hood.
Solution Approach 2:
The embossing process creates a localized deformation of the wall material that changes its geometric parameters, forming the trough and hood structures. This parameter change allows the creation of protective features without adding material, as the wall material itself is reshaped rather than supplemented.
2Reliability
If separate components are used for trough and hood, then the locking mechanism can be more secure, but the device complexity and production cost increase
Solution Approach 1:
The trough and hood are combined into a single embossed feature on the wall, reducing the number of components from two separate parts to one integrated structure. This simplifies the overall device complexity while maintaining the locking function through the unified geometry of the embossed feature.
Solution Approach 2:
The wall material itself serves the dual function of structural support and moisture protection by being embossed to form both the trough and hood. The wall structure performs the protective function that would otherwise require separate components, eliminating the need for additional parts and simplifying production.
3Ease of manufacture
If punched holes are used for recesses, then the production process is simpler, but moisture protection is reduced
Solution Approach 1:
The wall material undergoes a parameter change through embossing, transforming from a flat surface to a three-dimensional trough-hood structure. This deformation maintains the closed nature of the wall for moisture protection while creating the necessary recesses for locking, avoiding the need for punched holes that would compromise waterproofing.
Solution Approach 2:
The solution moves from a two-dimensional punched hole approach to a three-dimensional embossed structure. By adding depth and volume to the wall surface through embossing, the design creates functional recesses that maintain the continuous barrier against moisture, eliminating the need for open punched holes.
4Reliability
If the trough and hood extend far beyond the recess, then moisture protection is improved, but the material usage and production cost increase
Solution Approach 1:
The trough and hood are merged into a single embossed feature that efficiently protects against moisture from multiple directions. This integrated design provides comprehensive protection with minimal material extension beyond the recess, as the unified geometry creates effective barriers without requiring excessive depth or width in either the trough or hood individually.
Solution Approach 2:
The embossing process creates precise geometric parameters for the trough and hood that optimize moisture protection while minimizing material usage. By controlling the depth, width, and angle of the embossed feature, the design achieves effective protection against rain and spray without extending far beyond the recess boundaries.
