Sink Rim Flange Design for Flush Mount Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sink designs, particularly stainless steel sinks, face challenges in supporting the weight in flush-mounted configurations and achieving a truly flush mount due to thinner and narrower peripheral mounting flanges, leading to gaps and aesthetic issues.
Innovation Solution
A sink assembly with a thicker and wider outwardly extending peripheral mounting flange made of type 304 stainless steel, welded to form a unitary sink unit, allowing for three mounting methods (drop in, under mount, and flush mount) with square exterior edges for enhanced support and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a thinner and narrower peripheral mounting flange is used, then the sink assembly can be more easily installed and has less material cost, but the sink cannot provide adequate support in flush-mounted configurations and creates gaps
Solution Approach 1:
The patent changes the dimensional parameters of the peripheral mounting flange by increasing its thickness and width. This parameter change allows the flange to provide adequate support for flush-mounted configurations while maintaining ease of installation through the same flange structure that serves all three mounting methods.
Solution Approach 2:
The peripheral mounting flange is designed to serve multiple functions across three different mounting methods (drop in, under mount, and flush mount). By making the flange thicker and wider, it can adequately support the basin weight in flush-mounted configurations while still being compatible with the other mounting methods, eliminating the need for separate flange designs for each method.
2Strength
If a thicker and wider peripheral mounting flange is used, then the sink provides adequate support in all mounting configurations and eliminates gaps, but the sink assembly requires more material and has increased manufacturing complexity
Solution Approach 1:
The thicker and wider peripheral mounting flange is designed to serve all three mounting methods (drop in, under mount, and flush mount) with a single unified structure. This universality avoids the need for multiple separate flange designs or complex assembly procedures, thereby limiting the increase in manufacturing complexity despite the increased material requirements.
3Quantity of substance
If a thinner peripheral mounting flange is used, then the sink assembly has less material cost and simpler construction, but it creates gaps and aesthetic issues in flush-mounted configurations
Solution Approach 1:
The patent increases the thickness and width parameters of the peripheral mounting flange to eliminate gaps and achieve proper flush mounting. This parameter change ensures that the sink surface is properly aligned with the countertop surface, creating a seamless appearance while using a reasonable amount of material.

Function Achieved in This Case
The solution provides adequate support for the sink basin in all mounting configurations, eliminating gaps and ensuring a visually harmonious transition with the countertop, enhancing both functionality and appearance.
Implementation Method 1
The peripheral mounting flange is welded to the basin along the periphery of the plurality of downwardly depending basin walls

AI summary
A sink assembly includes a basin formed of a metallic material. The basin has a plurality of downwardly depending basin walls. The basin also includes an outwardly extending peripheral mounting flange comprising a flat upper surface and a flat lower surface. The peripheral mounting flange is welded to the basin along the periphery of the plurality of downwardly depending basin walls and extends along a single plane. The peripheral mounting flange is capable of supporting the entire weight of the basin without flexing when the sink is installed in a flush mounted configuration. The sink assembly also includes clips configured to be secured to a countertop, and adjustment screws adjustably coupled with the clips. The adjustment screws are vertically adjustable to support the peripheral mounting flange so that the upper surface of the peripheral mounting flange is flush with the countertop.
