Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foundation structures for vertical poles, such as streetlights and cellular towers, are inefficient in terms of material usage, production time, and cost, and are prone to corrosion due to their reliance on concrete and embedded anchor bolts.
Innovation Solution
A cellular foundation structure with internal vertical walls and a pole cap that distributes stress loads, uses additive technology for fabrication, and incorporates a tapered design to reduce material usage and installation time, while minimizing corrosion risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional concrete foundations with embedded anchor bolts are used, then structural stability is achieved, but material usage increases and corrosion resistance decreases
Solution Approach 1:
The foundation employs a cellular structure with voids that reduce material quantity while maintaining structural integrity. The cellular design provides inherent corrosion resistance by eliminating the need for embedded metal anchor bolts in concrete, thereby reducing both material usage and corrosion susceptibility.
Solution Approach 2:
The foundation combines cellular structural elements with alternative anchoring mechanisms that eliminate the need for traditional concrete-with-embedded-bolts construction. This composite approach uses the cellular structure itself as both the load-bearing element and the corrosion-resistant feature.
2Strength
If conventional concrete foundations are used, then structural strength is achieved, but production time increases
Solution Approach 1:
The foundation is segmented into modular cellular units that can be pre-fabricated and then assembled. This segmentation allows for parallel production of multiple foundation units simultaneously, significantly reducing overall production time while maintaining structural strength through the distributed cellular architecture.
Solution Approach 2:
The cellular foundation structure can be pre-fabricated in controlled manufacturing environments before installation at the site. This preliminary action enables quality control and structural strength verification during manufacturing, while expediting on-site installation compared to pouring conventional concrete foundations.
3Stability of the object's composition
If conventional foundations with embedded bolts are used, then pole anchoring is achieved, but installation complexity increases
Solution Approach 1:
The invention extracts and eliminates the complex embedded anchor bolt system from the foundation design. Instead of embedding bolts in concrete during construction, the cellular structure provides anchoring through its inherent geometric configuration and material properties, dramatically simplifying the installation process while maintaining pole anchoring stability.
4Strength
If solid material foundations are used, then structural integrity is achieved, but material cost increases
Solution Approach 1:
The cellular structure uses porous or void-containing material configuration to achieve structural integrity with reduced material quantity. The geometric arrangement of cells provides structural strength while using significantly less material compared to solid foundations, thereby reducing material cost while maintaining structural integrity.
