Triangular Post Holder Stability on Uneven Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior art post holders for safety posts are not stable enough, particularly on uneven surfaces, and fail to provide adequate support in various applications.
Innovation Solution
A post holder design featuring an elongate post reception portion with a central support portion and laterally extending side support portions forming a triangular three-point support, along with a fastening system that includes a bridge plate and adjustable threaded pin, ensures stability on uneven surfaces and allows for secure fastening with smaller fastening means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a prior art post holder with a single support portion is used, then the structure is simple, but the stability is insufficient
Solution Approach 1:
The support portion is divided into three separate support portions (first, second, and third support portions) that protrude in different directions from the post reception portion. This segmentation provides three-point support on the base, significantly improving stability while maintaining reasonable structural simplicity.
2Area of stationary object
If a prior art post holder with a long bottom surface is used, then the fastening area is large, but the performance on uneven surfaces is poor
Solution Approach 1:
The bottom surface is segmented into three separate support portions instead of a continuous long bottom surface. Each support portion makes contact at a discrete point, allowing the post holder to accommodate uneven surfaces effectively while still providing adequate fastening area through the distributed contact points.
Solution Approach 2:
The support portions protrude in different directions (first and second perpendicular to each other, third in opposite direction to first), creating a three-dimensional distribution of contact points. This spatial arrangement improves adaptability to uneven surfaces while maintaining fastening capability.
3Device complexity
If a prior art post holder without lateral support portions is used, then the structure is simple, but the ability to absorb side forces is insufficient
Solution Approach 1:
The support structure is segmented into multiple support portions positioned in different directions. The first and second support portions are arranged perpendicular to each other, creating lateral extension that effectively absorbs side forces in multiple directions while maintaining structural simplicity.

AI summary
This invention relates to a post holder (200) for holding a safety post on a horizontal structure of a building. The post holder has an elongate post reception portion (202), an elongate central support portion (204), protruding from the post reception portion and perpendicular to the post reception portion, and first and second elongate side support portions (206,208) protruding from the post reception portion laterally of the central support portion and in opposite directions. The central support portion comprises a fastening seat, which is arranged to receive a fastening member for fastening of the post holder to a base.
