Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric vehicle charging devices are inconvenient for outdoor use due to the need for users to physically check charge states or failures, especially in adverse weather conditions, as they lack effective resistance to temperature, humidity, and vibrations, and do not provide efficient communication of charge-related information.
Innovation Solution
A charging device assembly for electric vehicles that includes a detachable charge control device with an ad-on communication unit for wireless short-distance communication, allowing for infrared communication between the charge control device and a terminal, enabling users to monitor charging operations and states remotely through a wireless communication system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the charge control device is disposed outdoors for stable charging, then charging reliability is improved, but user convenience deteriorates because users must physically check charge states or failures in adverse weather conditions
Solution Approach 1:
The patent introduces a communication device as an intermediary between the charge control device and the user. This device receives charge-related information from the charge control device and displays it to the user, eliminating the need for users to physically check the charging equipment in adverse weather conditions while maintaining outdoor charging capability
Solution Approach 2:
The patent replaces the mechanical approach of physically checking charge states (users needing to be close to the device and visually inspect LEDs) with a wireless communication system that transmits charge information electronically to the user's terminal device, allowing remote monitoring without physical contact
2Loss of information
If the charge control device provides various charge-related information through LED indicators, then information transmission is achieved, but user convenience deteriorates because users must come close to check the information
Solution Approach 1:
The communication device acts as an intermediary that receives charge-related information from the charge control device and relays it to the user's terminal device. This allows users to access charge information remotely through their personal devices without needing to physically approach the charging equipment
Solution Approach 2:
The patent creates a copy of the charge control device's information output by transmitting the charge-related data through wireless communication to the user's terminal device. The terminal device displays a replicated version of the charge status information, allowing users to view it from any location
3Ease of manufacture
If the charge control device is made detachable from the cable, then ease of installation is improved, but device complexity increases due to additional coupling mechanisms
Solution Approach 1:
The patent divides the charging system into separable components: the charge control device and the cable assembly. The charge control device can be independently attached to or detached from the cable through a coupling mechanism, allowing flexible installation and maintenance while keeping the overall system design relatively simple through standardized interfaces

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides users with the ability to monitor charging operations and states from a distance, enhancing convenience and usability, especially in harsh weather conditions, while maintaining resistance to environmental factors and reducing costs by allowing optional purchase of additional communication components.
Implementation Method 1
The charge control device and the ad-on communication device may perform infrared (IR)-ray communication with each other
