Portable Footing Foundation Anchoring and Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable decking, stairs, and accessibility ramp systems require multiple footing foundation materials and anchoring methods to meet uplift and downward load requirements, leading to complexity and potential instability.
Innovation Solution
A portable footing foundation with strategically positioned bolt holes and multiple anchoring options, including drive pins and cross drive anchoring, provides a lightweight, strong composite solution that can replace traditional foundations and enhance weight distribution and uplift capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple footing foundation materials and anchoring methods are used to meet uplift and downward load requirements, then the structural stability is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple anchoring methods (straps and anchoring bolts) into a single integrated footing foundation unit that can simultaneously handle both uplift and downward loads, eliminating the need for separate anchoring components and reducing installation complexity
Solution Approach 2:
The footing foundation is designed as a multi-functional component that provides both structural support for downward loads and anchoring capability for upward winds loads, replacing the need for multiple specialized components with a single versatile unit
2Strength
If traditional wooden, composite, or concrete footing foundations are used, then the load-bearing capacity is sufficient, but the weight of the foundation increases
Solution Approach 1:
The patent employs composite materials in the footing foundation construction, combining materials with high strength-to-weight ratios to achieve adequate load-bearing capacity while significantly reducing the overall weight compared to traditional solid concrete or wooden foundations

AI summary
Anchor pads are a portable foundation to support the weight of a portable structure. Anchor pads also anchor to the ground to withstand wind loads or other vertical loads on the portable structure. Anchor pads can be stacked to form larger portable foundations to support more weight or larger structures.
