Lockable Charging Housing for Motor-Assisted Bicycles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for charging electric vehicle batteries are not adapted to meet the specific needs of motor-assisted single-track vehicles, such as bicycles, and lack effective measures to prevent misuse during charging.
Innovation Solution
A device with a lockable housing for each vehicle, where the door locks automatically and can only be actuated via a control device connected to an input and display system, ensuring only authorized users can access and charge their vehicles, with the power switch controlled based on the lock's position to connect to the electrical supply network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex circuit is used to prevent misuse in existing charging devices, then charging security is improved, but device complexity increases
Solution Approach 1:
The charging system is segmented into separate functional modules: individual housings for each vehicle, separate lock mechanisms for each housing, and individual power switches for each socket. This segmentation allows each component to be simple while the overall system provides comprehensive security through coordinated operation of multiple independent units.
Solution Approach 2:
The system employs automatic locking when the housing door is closed, and the power switch automatically activates when the lock is engaged. This self-service mechanism eliminates the need for complex manual control circuits, as the system automatically manages its own security and power delivery based on the physical state of the housing and lock.
2Reliability
If automatic locking and controlled access are implemented, then misuse prevention is improved, but device complexity increases
Solution Approach 1:
The lock mechanism automatically engages when the housing door is closed, and the power switch automatically activates when the lock is engaged. This self-service approach allows the system to provide sophisticated security and access control without requiring complex control circuits, as the physical state changes automatically trigger the appropriate responses.
Solution Approach 2:
The lock mechanism serves as an intermediary between the housing door and the power switch. The power switch is controlled based on the lock's position, creating a simple hierarchical control relationship where the lock state mediates the power delivery, eliminating the need for complex authorization and control systems.
3Reliability
If individual housings with automatic locking are used for each vehicle, then charging security is improved, but ease of operation decreases
Solution Approach 1:
The automatic locking and unlocking mechanism eliminates the need for manual locking operations. When the user places the vehicle in the housing and closes the door, the lock automatically engages. When charging is complete and the user returns with authorization, the system automatically unlocks, providing secure operation without manual intervention.
