Sink Connector With Segmented Elastic Members for Fatigue Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors for sinks suffer from weak fatigue resistance due to a longer force arm between the first and third extension sections, leading to reduced durability.
Innovation Solution
A connector design featuring a main body with a vertical part, curved part, and multiple elastic members, including first, second, and third elastic pressing parts with specific folding sections and angles, to distribute force more evenly and reduce the force arm, enhancing fatigue resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the spring member has a longer force arm between the first extension section and the third extension section, then the spring member can provide greater support force, but the fatigue resistance of the spring member becomes weak
Solution Approach 1:
The spring member is divided into multiple extension sections (first, second, third extension sections) with different geometries. Each section has specific characteristics: the first extension section extends substantially perpendicular to the base body, the second extension section extends in an acute angle less than 30 degrees, and the third extension section is bent to a greater extent and widened. This segmentation allows each section to bear and distribute forces differently, reducing stress concentration and improving fatigue resistance while maintaining adequate support force.
2Device complexity
If the spring member has only the third extension section as the force-bearing point, then the structure is simplified, but the fatigue resistance becomes weak due to the longer force arm
Solution Approach 1:
Different sections of the spring member are given different local qualities and geometries. The first extension section has a perpendicular orientation, the second extension section has an acute angle orientation, and the third extension section is bent to a greater extent and widened. This creates multiple force-bearing points with varying mechanical properties along the spring member, distributing the stress and improving fatigue resistance without significantly increasing overall structural complexity.

AI summary
The present invention relates to the technical field of sink installation accessories, in particular to a connector for installing a sink, a sink and a sink assembly. The connector includes an integrally formed main body which comprises a vertical part; a lower end of the vertical part is bent to an upper right to form a curved part; the curved part extends to the upper right with several elastic members; and the elastic member comprises a first and a second elastic pressing part, wherein the second elastic pressing part is formed by cutting and bending a middle part of the first elastic pressing part, and a second folding section on the second elastic pressing part is located just below a first folding section on the first elastic pressing part, thereby sharing part of a force while shortening a force arm and further improving the fatigue resistance of the elastic member.
