Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric vehicle charging stations face the challenge of accommodating different charging plug types without requiring a complete overhaul, as the transition to the SAE J3400 charging standard necessitates compatibility with both AC and DC charging, while maintaining convenience, robustness, and secure storage.
Innovation Solution
A charger adapter system comprising a port to port adapter with magnetic counterparts, a mount, and a lock, allowing seamless conversion between SAE J1772 and J3400 connectors, securely attachable to the charger hose and head, with a tether and ring lock for theft prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If chargers are made easily accessible and convenient, then user convenience is improved, but security and robust storage during frequent use deteriorates
Solution Approach 1:
The adapter incorporates a dynamic design with movable components including a rotatable connector assembly and a collapsible or extendible tether mechanism. This allows the adapter to transition between a compact stored state and an extended operational state, providing both secure storage when not in use and easy accessibility when needed.
Solution Approach 2:
The adapter utilizes flexible materials and thin-walled structures that allow the tether and connector housing to bend and flex during operation. This flexibility enables the adapter to maintain structural integrity during frequent insertion and removal cycles while remaining compact for storage and resistant to damage from rough handling.
