Vehicle Charging Location Alerts for Resident Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Residents in neighborhoods experience distrust and anxiety when a power supply vehicle is parked on the street to charge vehicles, as they are unaware of its presence and activities.
Innovation Solution
An information transmission device that receives position information from power supply and general vehicles, generates display information, and transmits it to information terminals to inform residents about the power supply vehicle's location and activities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a power supply vehicle is parked on a street in a general residential area to charge vehicles, then charging service is provided to residents, but residents feel distrust and anxiety due to lack of information about the vehicle's presence
Solution Approach 1:
The system implements feedback by transmitting position information of the power supply vehicle to information terminals of nearby residents. The communication unit receives position information from the power supply vehicle and transmits it to residents' terminals, providing continuous updates about the vehicle's location and presence. This feedback mechanism eliminates information asymmetry and reduces resident anxiety.
Solution Approach 2:
The information transmission device acts as an intermediary between the power supply vehicle and residents. It receives position information from the vehicle and relays it to residents' information terminals, serving as a communication bridge that builds trust without requiring direct interaction between residents and the vehicle.
2Loss of information
If position information is transmitted to all information terminals in the area, then residents gain awareness and security, but communication bandwidth and energy consumption increase
Solution Approach 1:
The system applies local quality by transmitting position information selectively based on spatial proximity. The communication unit determines which information terminals are located in the vicinity of the power supply vehicle and transmits information only to those terminals. This localized information transmission reduces unnecessary communication overhead while ensuring relevant residents receive the information.
Data Source
AI summary
The information transmission device includes a communication unit and a control unit. The communication unit receives position information indicating the current position of the power supply vehicle from at least one of the power supply vehicle and the general vehicle when the power supply vehicle moves to the position of the general vehicle and charges the general vehicle. The control unit generates display information based on the received position information, and causes the communication unit to transmit the display information to one or more information terminals.
