Nested EV Charging Post Impact Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charging stations for electric vehicles in public areas lack adequate impact protection and vandalism prevention, posing risks due to potential mechanical damage and electrical hazards.
Innovation Solution
A charging station design featuring a crash protection system that can be securely connected to a concrete base, with an impact protection component made of thick sheet metal that covers the charging station, housing the electrical connections and a house junction box for enhanced safety and concealment, allowing easy installation and protection against buckling and vandalism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the charging station is made with thin sheet metal for aesthetic purposes and corporate design, then the visual appearance and branding freedom are improved, but the mechanical strength and resistance to impact and vandalism deteriorate
Solution Approach 1:
The patent implements a nested structure where the thin-walled charging station housing (for aesthetic purposes) is placed inside a thicker protective housing (for mechanical strength). The inner housing contains the electrical components and provides the corporate design appearance, while the outer housing provides impact protection and vandalism prevention. This nested arrangement allows both aesthetic requirements and mechanical strength requirements to be satisfied simultaneously.
2Ease of manufacture
If the charging station is installed directly on a concrete base without additional protection, then the installation simplicity is improved, but the protection against buckling and mechanical damage deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-attaching protective elements (such as steel plates or reinforced structures) to the charging station housing before installation on the concrete base. This allows the protective structure to be prepared in advance, maintaining installation simplicity while ensuring buckling protection is already in place before the station becomes operational.
3Ease of operation
If the electrical connections are exposed for easy access and maintenance, then the ease of operation is improved, but the vulnerability to vandalism and mechanical damage deteriorates
Solution Approach 1:
The patent introduces an intermediary protective structure (such as a sealed electrical compartment with controlled access or protective covers) that mediates between the need for electrical connection accessibility and the need to protect against vandalism. The intermediary element allows authorized access for maintenance while preventing unauthorized tampering, thus resolving the contradiction between ease of operation and vandalism protection.
