Battery Holder Notification for Locating Shared E-Mobility Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of rental and sharing services for electric-powered mobile objects face difficulty in locating available vehicles, especially at night when visibility is low, due to the vehicles not being easily recognizable.
Innovation Solution
A battery holder equipped with a notification device that transmits a wireless signal to facilitate easy recognition of the mobile object's location, and a mobile supply system that includes a terminal and control device to operate the notification device based on received signals, allowing users to identify the object using ID information and battery levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mobile vehicles are placed at a station without additional notification devices, then the device complexity is reduced, but the ease of operation deteriorates because users cannot easily recognize the location of mobile vehicles, especially at night
Solution Approach 1:
The notification device uses light emission (color changes) to make the mobile object location recognizable, especially at night. The light emitting unit changes the visual appearance of the mobile object by emitting light, allowing users to easily locate the mobile object without increasing structural complexity
Solution Approach 2:
The notification device acts as an intermediary between the mobile object and the user. It receives wireless signals from the terminal and converts them into visible/audible notifications, facilitating communication without requiring direct complex interaction between the user and the mobile object system
2Ease of operation
If a notification device with light emitting unit is added to the mobile object, then the ease of operation improves by enabling location recognition, but the weight of the moving object increases
Solution Approach 1:
The notification device uses LED lights which consume minimal power and emit sufficient light for location recognition. This partial action (using only enough light for the purpose) achieves location recognition without requiring excessive powerful light sources that would add significant weight
Solution Approach 2:
The system changes the operational parameters by using energy-efficient LED technology and controlling the light emission duration and intensity based on wireless signal reception, achieving effective notification with minimal energy and weight requirements
3Ease of operation
If the notification device operates continuously, then the ease of operation improves by always showing location, but the use of energy increases
Solution Approach 1:
The notification device operates periodically based on wireless signal reception from the terminal. Instead of continuous operation, it activates when needed (when a user sends a signal), significantly reducing energy consumption while maintaining ease of operation when required
Solution Approach 2:
The system uses feedback from wireless signals received from the terminal to control notification device operation. The device receives feedback (wireless signal) and activates accordingly, optimizing energy usage based on actual user need rather than operating continuously
