Anti-slip Bowl with Nested Shells for Secure Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing animal bowls with anti-slip materials face issues such as adhesion loss or detachment due to interference fits, making them difficult to clean and maintain, especially when exposed to high-pressure washers or dishwashers.
Innovation Solution
A bowl design featuring a rigid first shell and a second shell with non-continuous openings, where an anti-slip material is positioned between the shells, preventing detachment and allowing for easier cleaning and maintenance by eliminating the need for removal before washing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If anti-slip material is attached using adhesive or interference fit, then the material is initially secured to the bowl, but the material loses adhesion or falls out over time, especially when exposed to high-pressure washers or dishwashers
Solution Approach 1:
The bowl is divided into two separate shells: a first shell that provides the bowl structure and a second shell that serves as a base layer. The anti-slip material is positioned between these two shells, creating a segmented structure where each component has a specific function. This segmentation allows the anti-slip material to be secured mechanically rather than relying solely on adhesive or interference fit, resolving the adhesion loss problem.
Solution Approach 2:
The first shell is positioned within the second shell, creating a nested structure. The anti-slip material is nested between the two shells, with the protrusions of the anti-slip material extending through openings in the second shell. This nested arrangement secures the anti-slip material in place, preventing detachment during washing while maintaining the integrity of the bowl structure.
2Reliability
If anti-slip material is securely attached to prevent detachment, then the material remains in place during use, but the bowl becomes difficult to clean and maintain
Solution Approach 1:
By segmenting the bowl into two removable shells with the anti-slip material positioned between them, the design allows for easy disassembly for cleaning. The shells can be separated to access and clean the anti-slip material without requiring detachment of adhesive-bonded materials, thus maintaining both stability and ease of cleaning.
Solution Approach 2:
The anti-slip material is extracted from a permanently bonded state and repositioned between two shells where it can be easily accessed and removed for cleaning. The protrusions extending through openings allow the material to be pulled out or accessed without damaging the bowl structure, facilitating maintenance while keeping the material securely in place during normal use.
3Reliability
If anti-slip material is positioned between two shells, then the material is prevented from detaching, but the device complexity increases
Solution Approach 1:
The bowl is segmented into two shells that can be manufactured using standard processes. The anti-slip material with protrusions is a simple component that fits between the shells. This segmentation achieves secure attachment without requiring complex adhesive systems or interference fit mechanisms, as the protrusions through openings provide simple mechanical retention.
Solution Approach 2:
The nested shell structure provides a straightforward solution for securing the anti-slip material. The first shell nests within the second shell, with the anti-slip material positioned between them. This nested arrangement is structurally simple and easy to manufacture, achieving reliable attachment security without significant increase in device complexity.

AI summary
An anti-slip bowl is described herein. A bowl can include a rigid first shell including a base and an outer wall continuously attached to the base, a rigid second shell including a base and an outer wall continuously attached to the base, and an anti-slip material positioned between the rigid first shell and the rigid second shell and protruding through a number of openings on the rigid second shell.
