Clamping Device for Sink Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for attaching sinks to countertops, especially those made of hard surfaces like granite, are time-consuming and prone to failure due to human error, and often require expensive equipment and difficult installation processes.
Innovation Solution
A clamping device system that includes a clamp with a binding post and screw for secure attachment of a sink to a countertop, allowing for quick and easy installation without the need for specialized tools or complex procedures, enabling one-handed operation in confined spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional methods use clips with threaded inserts and epoxy for attaching sinks to granite countertops, then the sink can be securely attached, but the installation process becomes time-consuming and complex
Solution Approach 1:
The clamp is divided into distinct functional components: a clamp body for structural support, a binding tab for engagement with the countertop hole, and a clamp screw for applying clamping force. This segmentation allows each component to be optimized independently and simplifies the overall installation process.
Solution Approach 2:
The invention merges the functions of multiple conventional components (clip, threaded insert, and fastening mechanism) into a single integrated clamping device. The binding post combines the anchoring function with the clamping mechanism, eliminating the need for separate epoxy insertion and threading operations.
2Reliability
If conventional methods require drilling holes and inserting threaded inserts with epoxy, then secure attachment is achieved, but the process becomes difficult to perform in confined spaces
Solution Approach 1:
Instead of inserting components into the countertop from below (as in conventional methods), the binding post is inserted from the top side of the countertop through pre-drilled holes. The clamp body and binding tab then extend downward to engage with the sink, reversing the traditional assembly sequence and making installation accessible from above the countertop surface.
3Reliability
If conventional methods use spring clips that require hammering into place, then the sink can be attached, but the risk of damaging the sink and countertop increases
Solution Approach 1:
The invention replaces the hammering action required for conventional spring clips with a screw-based clamping mechanism. The clamp screw provides controlled, progressive clamping force that secures the sink without impact loads, eliminating the risk of damage associated with hammering while maintaining attachment security.
4Reliability
If conventional methods require cutting slots into the countertop for L-shaped spring clips, then attachment is achieved, but the equipment cost and installation complexity increase
Solution Approach 1:
The invention extracts the slot-cutting requirement entirely from the installation process. Instead of requiring L-shaped clips that must be hammered into slots, the binding post is inserted through standard holes drilled adjacent to the sink perimeter. This eliminates the need for specialized slot-cutting equipment and complex clip geometry while maintaining secure attachment.

AI summary
A clamping device for mounting a sink to a counter, includes a clamp having a clamp body and a binding tab, a binding post for insertion through a first opening in the clamp body and into a hole in a surface of the sink adjacent to a clamped article, the clamp and binding tab connected to the post and extending away therefrom at least partially over an edge of the clamped article, and a clamp screw for insertion through a second opening in the clamp body and against a solid portion of the binding tab interposed between the clamp screw and the edge of the clamped article.
