Solution Overview

Problem

Existing undermount sink mounting techniques are not compatible with laminate countertops, leading to aesthetic and functional issues, and there is a lack of solutions for integrally mounting stainless steel undermount sinks to both laminate and solid surface countertops.

Innovation Solution

An undermount sink design featuring a mounting flange and flange support made from stainless steel, which is mechanically fastened to the sink bowl and bonded to the countertop using adhesives, allowing for secure and aesthetically pleasing installation on both laminate and solid surface countertops.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional undermount sink mounting techniques are used, then the installation is suitable for solid surface countertops, but it is entirely inoperable with laminate countertops

Engineering Contradiction:

Improvecompatibility with countertop materialsVSAvoidmounting stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The mounting system is divided into separate components: a mounting flange that attaches to the sink bowl and extends through the countertop, and a separate mounting structure that secures the flange to the countertop. This segmentation allows the same basic structure to be adapted to different countertop materials by changing only the attachment method, not the entire mounting system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The mounting flange acts as an intermediary element between the sink bowl and the countertop. It provides a standardized interface that can work with different countertop materials (laminate, solid surface, granite) by using different attachment techniques for each material type, thus resolving the incompatibility issue.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If adhesive bonding is used to mount the sink, then the mounting is secure, but the exposed substrate edges are aesthetically undesirable and prone to water damage

Engineering Contradiction:

Improvemounting securityVSAvoidwater damage to substrate

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The mounting flange is designed to extend through the countertop surface, extracting the mounting function from the substrate material itself. This creates a barrier that prevents water from reaching and damaging the substrate edges, while the flange's outer surface provides a water-resistant barrier that maintains aesthetic appearance.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The mounting flange creates a flexible barrier system that seals around the sink opening. This thin film-like structure prevents water penetration to the substrate while maintaining the aesthetic appearance of the countertop edge, solving both the water damage and aesthetic issues.

Inventive Principle:

Principle #30Flexible shells and thin films

3Reliability

If a rim is added to retain the sink, then the sink is securely retained, but it lacks aesthetic qualities and retains moisture and debris

Engineering Contradiction:

Improvesink retentionVSAvoidmoisture and debris accumulation

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The retention function is extracted from a traditional rim structure and relocated to a mounting flange that sits beneath the countertop surface. This removes the aesthetic and hygiene problems of exposed rims while maintaining the secure retention function through adhesive bonding and mechanical fastening to the countertop.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The mounting structure is moved from the horizontal plane (rim at the surface) to the vertical dimension (flange extending through the countertop thickness). This dimensional change allows the retention mechanism to be hidden beneath the surface, eliminating aesthetic and moisture accumulation issues while maintaining retention security.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

An undermount sink that can be integrally mounted to a laminate or solid surface countertop. The undermount sink has a novel mounting structure to accomplish mounting to a laminate countertop. A mounting flange is attached to an outer perimeter of the undermount sink bowl, and is reinforced by way of a mounting flange support within the mounting flange that is mechanically fastened to the upper outer perimeter of the undermount sink bowl.
