Segmented Pile Foundation System for Load Transfer Without Excavation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foundation systems often require extensive excavation and soil manipulation, leading to environmental damage and disruption of natural drainage patterns, particularly in sensitive ecosystems or areas with poor soil drainage or high water tables, making it challenging to transfer load from buildings to the soil effectively.
Innovation Solution
A multiple pile foundation system comprising a support frame with foundation components connected at selectively spaced intervals, featuring angularly driven piles and a locking mechanism to distribute structural loads without extensive excavation, preserving existing land contours and drainage properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional foundation systems are used, then load transfer from building to soil is achieved, but extensive excavation and soil manipulation are required causing environmental damage
Solution Approach 1:
The foundation system is divided into multiple discrete piles rather than a continuous excavated foundation. Each pile independently transfers load to bearing strata, eliminating the need for extensive continuous excavation while maintaining load transfer reliability.
Solution Approach 2:
The patent introduces a pinned connection system as an intermediary between the building structure and the piles, allowing flexible load transfer without requiring rigid excavation-based foundations. This mediator enables load transfer while preserving natural soil conditions.
2Strength
If extensive excavation is performed, then foundation load support is achieved, but natural drainage patterns and land contours are disrupted
Solution Approach 1:
By segmenting the foundation into discrete pinned piles, the system provides adequate load support without removing or redistributing large volumes of soil, thereby preserving natural land contours and drainage patterns.
Solution Approach 2:
The foundation system applies support locally through individually positioned piles at specific load-bearing points, rather than through extensive area-wide excavation. This localized approach maintains overall site topology and drainage characteristics.
3Object-affected harmful factors
If multiple pile foundation system is used, then excavation is minimized, but complex locking mechanisms are required to secure piles
Solution Approach 1:
The pinned connection system is designed to be self-aligning and self-securing through simple interlocking geometry. The piles and connections engage automatically through gravity and basic mechanical interlocking, eliminating complex locking mechanisms while maintaining excavation minimization benefits.
4Reliability
If conventional foundation systems are used, then structural load transfer is achieved, but site manipulation damages biological make up and soil integrity
Solution Approach 1:
The segmented pile system transfers structural loads through discrete points of contact with the soil, avoiding the large-scale soil removal and redistribution inherent in conventional foundations. This preserves soil integrity and biological communities throughout the site.
Solution Approach 2:
The pinned connection system serves as a mediator that transfers building loads to the ground without requiring direct, extensive contact between the structure and soil. This intermediary approach maintains soil structure and biological composition while achieving reliable load transfer.

AI summary
Foundation integral construction components and support systems where multiple pile foundation components are incorporated into a structure system that is connected to, or otherwise part of the foundation, can further reduce the need for excavation and thus preserve existing contours and drainage properties of the land. These multiple pile foundation systems, are applicable to a wide variety of site and soil conditions and a wide variety of surface structures or buildings. The multiple pile foundation system can reduce the need for site excavation, drainage control, and soil backfill by transferring load from a portion of a structure to the ground.
