Rimless Undermount Sink Mounting Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stainless steel sink installations, such as topmount and undermount sinks, create interfaces that allow water, moisture, bacteria, and debris to accumulate, leading to unsanitary and visually unappealing conditions, especially when mounted on solid countertops like granite or marble.
Innovation Solution
A seamless undermount stainless steel sink system with a rimless upper edge and a mounting assembly that includes brackets with sink and countertop flanges, secured at a predetermined depth, to prevent water and debris from entering between the sink and the countertop, utilizing a seal to create a virtually seamless interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a topmount sink with flange is used, then the sink can be easily mounted to the countertop, but water and debris accumulate at the interface between the flange and countertop creating unsanitary conditions
Solution Approach 1:
The patent removes the traditional flange structure from the sink and extracts the mounting function to a separate mounting assembly that attaches to the underside of the countertop. This eliminates the horizontal interface between flange and countertop surface where water accumulates, while preserving the mounting capability through vertical attachment from below.
Solution Approach 2:
Instead of mounting the sink from above with the flange resting on the countertop surface, the patent inverts the mounting approach by attaching the mounting assembly to the underside of the countertop and securing the sink from below. This inversion eliminates the problematic horizontal interface and creates a seamless appearance at the countertop surface.
2Shape
If an undermount sink with flange is used, then the sink can be mounted below the countertop surface, but water and debris still accumulate at the interface between the flange and countertop
Solution Approach 1:
The patent removes the traditional flange structure from the undermount sink configuration and extracts the sealing and mounting functions to separate components. The mounting assembly attaches to the underside while the rimless upper edge provides the seal, eliminating the horizontal interface where water accumulates.
Solution Approach 2:
The patent inverts the traditional undermount approach by eliminating the flange that extends horizontally toward the countertop surface. Instead, the mounting occurs vertically from below through the mounting assembly, and the seal is created at the vertical interface between the rimless edge and countertop, preventing water accumulation.
3Shape
If a flush-mount sink with narrow flange and recess is used, then a flush appearance can be achieved, but considerable time, expense, expertise, and special equipment are required to cut the recess
Solution Approach 1:
The patent removes the requirement for cutting a recess into the countertop by extracting the flush-mounting function to a separate mounting assembly that attaches to the underside of the countertop. The sink itself maintains a rimless design that sits flush with the countertop surface without requiring any recess modification.
Solution Approach 2:
Instead of cutting a recess into the countertop to accommodate a narrow flange, the patent inverts the approach by mounting the sink from below through the countertop surface. The mounting assembly attaches to the underside, eliminating the need for complex recess cutting while achieving a flush appearance.
4Shape
If a rimless sink design is used, then a seamless appearance can be achieved, but the sink requires specialized mounting methods to prevent water infiltration
Solution Approach 1:
The patent segments the mounting function from the sink body by using a separate mounting assembly that attaches to the underside of the countertop. This segmentation allows the sink to maintain its rimless seamless design while the mounting assembly handles the sealing and attachment functions through vertical mounting from below.
Solution Approach 2:
The patent introduces a mounting assembly as an intermediary component between the rimless sink and the countertop. This intermediary handles the sealing and mounting functions, allowing the sink itself to remain simple and rimless while the intermediary manages the complexity of preventing water infiltration.

AI summary
A seamless undermount sink system includes a solid countertop having a sink mounting aperture defining an inner periphery disposed therethrough. The system also includes a sink having a sidewall with a rimless upper edge defining an outer periphery therearound. A mounting assembly is attached to a portion of the sink, and an interface is formed between the sink and the solid countertop. A sealing assembly is disposed in the interface between the rimless upper edge of the sink and the solid countertop to prevent water, food, or other debris from getting in between the sink and the solid countertop.
