Bowl Anti-Slip Attachment via Mechanical Interlocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-slip materials for animal bowls, such as those attached using adhesives or interference fits, tend to detach or fall out, making them difficult to clean and maintain, and are not securely integrated with the bowl.
Innovation Solution
Integrating an anti-slip material between two shells, where the base of one shell has non-continuous openings and the anti-slip material has corresponding protrusions that protrude through these openings, securely attaching the anti-slip material to the bowl and allowing for easy cleaning and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If anti-slip material is attached using adhesive, then the material is initially secured to the bowl, but the material loses adhesion and detaches over time
Solution Approach 1:
The bowl is divided into two separate shells (first shell and second shell) with the anti-slip material positioned between them. This segmentation allows the anti-slip material to be mechanically trapped between the shells rather than relying on adhesive attachment to a single surface, thereby improving both attachment reliability and duration.
Solution Approach 2:
The anti-slip material is nested between the first shell and second shell, with protrusions extending through openings in the second shell. This nested configuration secures the anti-slip material in place through mechanical interlocking, preventing detachment over time without relying on adhesive bonds.
2Reliability
If anti-slip material is attached using interference fit, then the material is secured within the bowl, but the material falls out of the interference fit
Solution Approach 1:
By segmenting the bowl into two shells with the anti-slip material positioned between them, the design creates a more reliable mechanical retention system. The anti-slip material is prevented from falling out by the combination of the first shell's inner surface and the second shell's structure with protrusions through openings.
Solution Approach 2:
The attachment mechanism transitions from a two-dimensional surface attachment (adhesive or interference fit on a single surface) to a three-dimensional mechanical interlocking system where the anti-slip material is trapped between two shells with protrusions extending through openings, adding a vertical dimension to the retention mechanism.
3Reliability
If anti-slip material is securely integrated with the bowl, then the material remains attached during use, but the bowl becomes difficult to clean and maintain
Solution Approach 1:
The bowl is segmented into two removable shells with the anti-slip material positioned between them. This segmentation allows the shells to be separated for cleaning, maintaining ease of operation while securing the anti-slip material through mechanical interlocking rather than permanent adhesive bonds.
Solution Approach 2:
The design transitions from a static, permanently bonded attachment system to a dynamic, removable system where the two shells can be separated for cleaning and reassembled for use. The anti-slip material remains securely positioned between the shells during use but allows easy access for maintenance.

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, wherein the base of the rigid second shell includes a number of non-continuous openings, and an anti-slip material positioned between a lower side of the base of the rigid first shell and an upper side of the base of the rigid second shell.
