Conical Stud Support Structure for Side-Load Shear Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Threaded studs with flanged base plates fail under sideways loads due to shear or fatigue, necessitating a more effective support solution.
Innovation Solution
A hollow truncated cone support with a threaded apex aperture and base aperture, providing a cone chamber to house the stud and protect it from shear forces, offering enhanced strength with minimal weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If threaded studs with flanged base plates are used to fasten items via bonding, then the bonding connection is established, but the studs fail under sideways loads due to shear or fatigue
Solution Approach 1:
The support structure is divided into multiple functional segments: a conical support member with threaded aperture for stud reception, a flanged base plate for bonding attachment, and integrated reinforcement elements. This segmentation allows each component to specialize in resisting specific stress types, with the conical geometry handling shear loads and the flanged base providing stable bonding support.
Solution Approach 2:
The support structure employs composite construction combining the conical support member, flanged base plate, and reinforcement elements into an integrated assembly. This composite approach creates a structure where different geometric features work together to resist combined loading conditions, providing superior strength and fatigue resistance compared to simple stud designs.
2Strength
If a cone support is added to protect the stud, then strength against shear forces is enhanced, but the weight of the system increases
Solution Approach 1:
The conical geometry of the support member provides structural efficiency by distributing shear forces through its tapered walls. The curved conical surface is inherently stronger than flat plates of equivalent weight, allowing the structure to resist sideways loads on the stud while minimizing material usage and overall weight.
Solution Approach 2:
The conical support member functions as a thin-walled structural shell that efficiently resists shear forces through its geometry rather than through massive material sections. The conical shell structure provides high strength-to-weight ratio, protecting the stud from shear loads without adding excessive weight to the system.

AI summary
A cone support for use with a stud, the cone support includes a hollow truncated cone with an apex and a base. The hollow truncated cone includes an apex aperture disposed at the apex and a base aperture disposed at the base. The apex aperture has a threaded internal diameter. The apex aperture and base aperture communicate within a cone chamber, the cone chamber is disposed within the interior of the cone and between the apex aperture and the base aperture. The stud is placeable within the apex aperture, the cone chamber and the base aperture such that the cone support protects the stud from shear forces when the stud is stressed perpendicular to its axis.
