Modular Tower Foundation with Adjustable Connecting Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional tower foundations are expensive, inflexible, and difficult to transport, especially to remote locations, as they require concrete footings that are designed for specific loads and cannot be easily adapted for different tower sizes or equipment types, leading to excessive construction costs and potential hazards when locations change.
Innovation Solution
A modular foundation system with adjustable connecting members and ballast holders that can be disassembled for transport, allowing the footprint to expand or contract based on load requirements, using the same central hub and ballast holders for various tower sizes and types, enabling efficient assembly and adaptation to different loading conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional concrete foundations are used, then the tower can be securely supported, but the construction cost increases and the foundation cannot be moved or adapted to different tower sizes
Solution Approach 1:
The foundation is divided into modular components including a central portion, multiple ballast holders, and connecting members that can be assembled and disassembled. This segmentation allows the foundation to be adapted to different tower sizes by adjusting the configuration of modular components while maintaining structural stability through proper connection and ballast distribution.
Solution Approach 2:
The foundation transitions from a static concrete structure to a dynamic modular system where connecting members can be adjusted in length and configuration. This dynamic design enables the foundation to adapt to different tower heights and load requirements by modifying the span between ballast holders, while maintaining reliability through engineered connection mechanisms.
2Reliability
If concrete foundations are poured for each specific tower location, then the tower can be securely installed, but the cost increases and the foundation cannot be reused at different locations
Solution Approach 1:
The foundation is segmented into transportable modular components that can be disassembled, shipped to different locations, and reassembled. This eliminates the need for permanent concrete pouring at each site while maintaining installation security through engineered connections and ballast holders that provide stable support at each location.
Solution Approach 2:
The modular foundation components are designed to be universal and can be used at multiple different locations and for different tower configurations. The same central portion, ballast holders, and connecting members can be reused across various projects, eliminating the need to pour new concrete foundations at each site while maintaining secure installation.
3Strength
If a single foundation design is used for maximum load capacity, then the tower can support the heaviest equipment, but the construction cost increases for towers that require less capacity
Solution Approach 1:
The foundation uses adjustable connecting members with variable lengths that can be configured to match the specific load requirements of different towers. This dynamic adjustment allows the foundation to provide maximum load capacity when needed while using fewer and shorter connecting members for lighter loads, reducing construction costs while maintaining adequate strength.
Solution Approach 2:
The foundation design allows for parameter changes in the connecting member lengths and ballast holder configurations to match the specific load requirements of different towers. By adjusting these parameters, the foundation can be optimized for each specific application, providing adequate strength for the required load while minimizing material usage and construction costs for lighter-duty applications.
4Device complexity
If the foundation footprint is fixed for a specific tower size, then the structure is simple to construct, but it cannot be adapted to different tower heights and equipment loads
Solution Approach 1:
The foundation is segmented into modular components with standardized connection interfaces, allowing for simple assembly while maintaining adaptability. The central portion, ballast holders, and connecting members can be easily assembled and disassembled, and the footprint can be adjusted by reconfiguring the modular components to match different tower configurations.
Solution Approach 2:
The foundation transitions from a fixed footprint design to a dynamic modular system where connecting member lengths can be adjusted. This dynamic design maintains relative structural simplicity through standardized components and connection mechanisms while enabling adaptation to different tower heights and equipment loads by modifying the span between ballast holders.

AI summary
A foundation for a tower includes a plurality of ballast holders spaced from each other and a central portion configured to support a tower. The foundation includes a plurality of connecting members, each connecting member configured to attach a ballast holder to the central portion, wherein a length of the plurality of connecting members is determined based upon the load capacity required to retain the tower in a vertical position, wherein when the plurality of ballast holders is connected to the central portion, the central portion is elevated above the plurality of ballast holders, wherein different lengths of the connecting members expands and contracts the footprint of the foundation to match the foundation to the required maximum loading requirements.
