Tiered Post Support Device for Single-Person Concrete Setting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current process of setting posts or piles in concrete-filled footing holes is labor-intensive and requires two builders, one to suspend the post and another to construct and maintain the stabilizing framework, which is cumbersome, especially for heavy or tall posts.
Innovation Solution
A support device comprising a lower tier and an upper tier separated by support walls, allowing the post or pile to be suspended and stabilized, enabling one builder to set and concrete the posts without additional support, with the device being adaptable for various post profiles and sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If one builder holds the post or pile while another constructs a stabilizing framework, then the post can be stabilized in position, but the process becomes labor-intensive and requires multiple workers
Solution Approach 1:
The support device is self-stabilizing through its tiered structure with support walls that distribute loads and provide inherent stability. The device supports itself and the post simultaneously, eliminating the need for external framework and multiple workers.
Solution Approach 2:
The support device acts as an intermediary between the post and the ground, providing a stable transition structure. The tiered design with support walls creates an intermediate platform that stabilizes the post without requiring additional framework.
2Strength
If a stabilizing framework of timber and braces is constructed, then heavy or tall posts can be prevented from toppling, but the device complexity and time required increase
Solution Approach 1:
The support device is divided into multiple tiers with support walls between them. This segmentation creates a modular structure that provides strength through distributed support rather than a single complex framework.
Solution Approach 2:
The tiered structure adds vertical dimensionality to the support system. Instead of a planar framework, the device uses stacked tiers with support walls to create three-dimensional stability that handles heavy and tall posts effectively.
3Measurement precision
If a builder checks post location while keeping it suspended, then positioning accuracy can be maintained, but the builder cannot relieve until concrete hardens
Solution Approach 1:
The support device maintains the post in the correct suspended position autonomously through its structured design. The tiered configuration with support walls inherently keeps the post centered and at the proper height, freeing the builder to perform other tasks.
Solution Approach 2:
The support device is prepared in advance with its tiered structure designed to automatically maintain proper post positioning. This preliminary configuration ensures the post remains accurately positioned without requiring continuous builder intervention during concrete setting.

AI summary
A support device adapted to support the base of a post or pile above the base of a foot hole excavated in preparation for pouring concrete having a lower tier adapted to contact the base of the foot hole and provide a support surface and an upper tier adapted to provide a post or pile supporting platform. The lower tier and the upper tier are separated by one or more support walls that define a region beneath the base of the post or pile to be filled with concrete.
