Seamless Sink Drain with Bayonet Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sink drains in commercial and industrial kitchen environments often have seams that collect food, bacteria, and debris, making them difficult to clean and maintain a sanitary condition.
Innovation Solution
A seamless drain system with an attachment bayonet and direct fluid injection capability, including a duo-strainer assembly and rubber splashguard, which allows for the direct injection of cleaning fluids like ozonated water to sanitize the drain area, and can be retrofitted to existing sinks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a traditional drain with flange is used, then the drain can be easily manufactured and installed, but the flange creates seams that collect food, bacteria, and debris making cleaning difficult
Solution Approach 1:
The patent removes the flange component entirely from the drain assembly, eliminating the seam where food and bacteria accumulate. The drain is designed to extend directly through the sink bottom without requiring a separate flange, thus extracting the problematic element while maintaining the drain's core function.
Solution Approach 2:
Instead of having the flange protrude outward from the sink bottom, the drain is inverted to extend downward through the sink bottom without a protruding flange. This inversion eliminates the crevice between flange and sink bottom, preventing debris accumulation while maintaining structural integrity.
2Object-affected harmful factors
If a seamless drain is implemented, then cleaning and sanitation are improved, but the drain requires more complex structure and installation
Solution Approach 1:
The drain assembly is designed to perform multiple functions: it provides drainage, acts as a seamless barrier preventing debris accumulation, and includes an integrated attachment mechanism for disposal systems. By combining these functions into a single universal component, the patent achieves sanitation benefits without proportionally increasing complexity.
Solution Approach 2:
The patent merges the drain body, the sealing mechanism, and the disposal system attachment interface into a single integrated assembly. This consolidation eliminates the need for separate flange components and multiple installation steps, achieving seamless construction without excessive complexity.
3Ease of operation
If an attachment bayonet is added to the drain, then disposal systems can be quickly attached and removed, but the drain structure becomes more complex
Solution Approach 1:
The attachment bayonet is designed with dynamic characteristics, allowing quick insertion and rotation to lock the disposal system in place. The bayonet mechanism can be easily engaged and disengaged by simple rotational motion, providing rapid attachment and removal capabilities without requiring complex tools or procedures.
Solution Approach 2:
The bayonet attachment mechanism is designed to be self-aligning and self-locking. The disposal system automatically aligns with the bayonet during insertion, and the rotational locking action is performed by the user's own motion without requiring additional components or complex adjustment mechanisms.

AI summary
A seamless drain system includes a sink basin having sidewalls and a bottom wall, and a seamless drain sidewall extending contiguously and below the bottom wall. The drain sidewall terminates in an attachment bayonet. The attachment bayonet includes an annular flange for removably coupling to a drainpipe adaptor or a disposal system. The sidewall includes a fluid line attachment stem for coupling a fluid line directly to the sidewall and drain. Accessories, such as a rubber splashguard or strainer basket, can be used in combination with a spray ring that nests within the drain sidewall and is in fluid communication with the fluid line, can be incorporated into the seamless drain system.
