Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foundation systems for structures and apparatuses are often inefficient due to their inability to match the base shape of the supported object, lack of onsite adjustment capabilities, and susceptibility to bending at hinge points, especially in remote locations where traditional installation methods are impractical.
Innovation Solution
A modular foundation system comprising hexagonal blocks with elongated holes in multiple directions and cables or bars that run through these holes, allowing for customizable configurations and post-tensioning to secure blocks without bendable points, ensuring stability and matching the base shape of the supported structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional onsite poured foundations are used, then stability and support are ensured, but transportation to remote locations becomes impractical and installation costs increase
Solution Approach 1:
The foundation system is divided into multiple discrete modular blocks that can be individually transported to remote locations and then assembled onsite. Each block contains integrated post-tensioning mechanisms, allowing the foundation to be shipped in manageable units rather than as a single monolithic structure.
Solution Approach 2:
The post-tensioning mechanisms are pre-installed within each modular block during manufacturing. This preliminary action eliminates the need for complex onsite tensioning operations and ensures that the blocks are ready for immediate assembly and stabilization upon arrival at the remote location.
2Adaptability or versatility
If rectangular blocks with post-tensioning mechanisms are used, then modular assembly is enabled, but hinge points are created that allow bending and weaken the foundation
Solution Approach 1:
The invention uses hexagonal-shaped blocks instead of traditional rectangular blocks. The hexagonal geometry, combined with strategically positioned elongated holes and post-tensioning cables running in multiple directions, eliminates hinge points at block joints. The cables are oriented at angles that prevent rotational movement and bending at the joints between adjacent blocks.
Solution Approach 2:
The post-tensioning cables run in three different directions through the hexagonal blocks, rather than just two directions as in traditional rectangular block systems. This three-dimensional cable arrangement creates a more robust connection that prevents bending and strengthens the overall foundation structure.
3Ease of manufacture
If foundation blocks are designed with fixed shapes, then manufacturing is simplified, but adaptability to match various base shapes of structures is reduced
Solution Approach 1:
The hexagonal block design serves multiple functions: it provides a standardized shape for simplified manufacturing and transport, while simultaneously offering geometric flexibility to create various overall foundation configurations. The elongated holes and cable arrangements can be oriented to match different base shapes of structures, making the same basic block type adaptable to various applications.
Solution Approach 2:
The foundation system allows for dynamic configuration during assembly. The modular hexagonal blocks can be arranged in different patterns and orientations to match the base shape of the structure being supported. The post-tensioning cables can be routed through different hole configurations to accommodate varying geometric requirements.
4Ease of manufacture
If anchor bolts are fixed in position during manufacturing, then production is streamlined, but onsite alignment with varying site conditions becomes problematic
Solution Approach 1:
The anchor bolts are not fixed in rigid positions during manufacturing. Instead, the modular block design incorporates flexibility that allows for onsite adjustment and realignment of anchor bolts to match varying site conditions and structure base positions, while still maintaining streamlined manufacturing processes.

AI summary
The present invention is directed to a customizable, modular foundation system using blocks and post-tensioning for improved structural integrity of the foundation. In some embodiments, the improved foundation system is provided by post-tensioning a plurality of blocks together such that cables or bars used for tensioning run in different directions than any of the joint lines between adjacent blocks. In this way, there are no bendable joints between adjacent blocks. Moreover, in some embodiments the blocks are hexagonal, such that each block has six sides and post-tensioning cables can run in at least three different directions. Structures or apparatuses may be secured to the foundation comprised of multiple blocks, with the foundation being rigid, customizable, and both assembled and usable in any desired location.
