Table Leg Socket Ribs for Stable Surface Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing table leg mounting sockets provide point contact, which can lead to instability and do not meet regulatory standards for the food service industry, particularly in terms of adherence and safety.
Innovation Solution
A leg socket with a hollow shell featuring circumferentially spaced elongated ribs with concavely curved surfaces for radial contact, a radially outward flange, a radially inward lip, and a threaded bore for secure assembly, fabricated to provide improved stability and adherence to industry standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a conventional socket without ribs is used, then the structure is simple and easy to manufacture, but the contact between socket and leg is point contact resulting in instability
Solution Approach 1:
The socket interior surface is segmented into multiple elongated ribs spaced circumferentially apart, transforming the continuous surface into discrete contact elements. Each rib has a concavely curved surface that contacts the leg, distributing the contact force across multiple points and improving stability while maintaining a relatively simple overall structure.
Solution Approach 2:
The contact interface is extended from point contact to surface contact by adding the elongated dimension to the ribs. The concavely curved surfaces of the ribs create radial contact surfaces that engage the leg over an extended area, transitioning from zero-dimensional point contact to two-dimensional surface contact.
2Reliability
If point contact between socket and leg is used, then the manufacturing is simple, but the adherence to regulatory standards is insufficient
Solution Approach 1:
The socket is segmented with multiple elongated ribs that create distributed contact surfaces. This segmentation transforms point contact into extended surface contact, improving reliability and adherence to food service industry standards while maintaining compatibility with conventional stamping operations.
Solution Approach 2:
The contact parameters are changed from point contact to surface contact by modifying the geometry of the socket interior. The elongated ribs with concavely curved surfaces increase the contact area and distribute contact pressure, changing the fundamental nature of the interface without requiring complex manufacturing processes.
3Stability of the object's composition
If radial contact surfaces are added to the socket, then the stability and adherence to standards are improved, but the device complexity increases
Solution Approach 1:
The socket structure is segmented into multiple elongated ribs that are circumferentially spaced apart. Each rib provides a radial contact surface with a concavely curved surface, creating distributed contact points that improve stability while maintaining a relatively simple overall structure that can be manufactured using conventional stamping operations.

AI summary
The leg socket has a plurality of circumferentially spaced apart ribs extending along an interior wall. Each rib has a concavely curved surface extending longitudinally and disposed on a common radius of the wall to provide contact with a cylindrical table leg over a surface.
