EV Charging Station Base With Four-Side Forklift Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric vehicle charging stations are heavy, costly, and vulnerable to tampering or theft when secured to the ground, as existing anchor bolt systems lack reliability and ease of installation in outdoor environments.
Innovation Solution
A secure base composed of uniform, high-strength steel beam members arranged in a configuration that facilitates transportation and installation, featuring anvil-horn shaped openings and mounting holes for secure fastening, with kick plates for cosmetic cover and protection, allowing forklift access from any side for improved maneuverability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If anchor bolts are used to secure charging stations to the ground, then the charging station is fixed in place, but the system lacks reliability and ease of installation in outdoor environments
Solution Approach 1:
The base is segmented into multiple beam members arranged in a grid pattern, with each beam providing independent anchoring points. This segmentation allows the system to be installed more easily while maintaining high securing reliability through distributed load bearing across multiple anchor points.
Solution Approach 2:
The base structure serves multiple functions: it anchors the charging station to the ground, provides a level mounting surface, facilitates transportation via forklift access through openings, and offers structural support. This multi-functionality resolves the contradiction by integrating reliability and installation ease into a single unified system.
2Reliability
If the charging station is secured to the ground, then it is protected against theft and tampering, but it becomes vulnerable to outdoor elements and requires complex anchoring systems
Solution Approach 1:
The anchoring function, structural support, and protective enclosure are merged into a single integrated base assembly. The beam members form a rigid framework that is both structurally sound and securely anchored, eliminating the need for separate complex anchoring systems while maintaining protection against tampering and theft.
Solution Approach 2:
The base utilizes composite construction combining steel beam members with concrete or masonry anchoring elements. This composite approach provides both the strength needed for theft prevention and the simplicity of installation by leveraging the complementary properties of different materials.
3Reliability
If a secure base structure is implemented, then protection against tampering and theft is enhanced, but transportation and installation become more challenging
Solution Approach 1:
The base structure incorporates horizontal openings through the beam members that allow forklift forks to access and engage the base from the side dimension. This dimensional approach to transportation access resolves the contradiction by enabling easy movement of the heavy secured structure without compromising the vertical anchoring security.
Solution Approach 2:
The base structure transitions from a static secured state to a dynamically movable state during transportation. The forklift engagement points allow the base to be lifted and moved when needed, while maintaining its secure anchored configuration during operation, thus resolving the contradiction between security and mobility.
4Ease of manufacture
If uniform beam members are used to form the base, then manufacturing and assembly are simplified, but the structural strength and stability may be compromised
Solution Approach 1:
While the beam members themselves are uniform for ease of manufacture, the local quality is enhanced through strategic placement of reinforcement bars within the beams and at connection points to the concrete anchor blocks. This allows standardization of the beam components while maintaining high structural strength where needed.
Solution Approach 2:
The uniform steel beam members are combined with concrete or masonry anchor blocks to create a composite structure. This composite approach allows the beams to be manufactured uniformly with consistent dimensions for easy assembly, while the concrete blocks provide the necessary structural strength and stability for securing the charging station.

AI summary
A secure base for a large piece of equipment, such as an electric vehicle charging station, includes a plurality of identical beam members having a generally rectangular-tubular shape, secured in a parallel arrangement to an underside of a baseplate. Each of the beam members includes a pair of opposing elongate openings defined by a bottom wall and sidewalls of the beam member. The beam members may be enclosed by kickplates secureable about a perimeter of the base. The preferred arrangement of the beam members, and the elongate openings therein, allow for receipt of blades of a forklift or pallet jack from all four sides of a piece of equipment mounted on the base.
