Electric Assist Bicycle Locking via UWB Position Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric assist bicycles require mechanical or electronic locks, which increase occupied space, cost, and manual operation requirements, and cannot be automatically unlocked or locked when the target user approaches.
Innovation Solution
A method and system that use position information from a UWB unit to automatically lock or unlock the electric assist bicycle based on the proximity and identity of the target user, eliminating the need for mechanical or electronic locks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical or electronic locks are added to the electric assist bicycle, then the locking and unlocking function is achieved, but the occupied space increases, cost increases, and manual operation is required
Solution Approach 1:
The patent replaces mechanical locks and electronic locks with a positioning-based control system. The control device obtains position information of the target user and automatically controls the locking and unlocking states without mechanical locking components, thus eliminating the need for complex locking mechanisms while maintaining security functionality.
Solution Approach 2:
The system enables automatic locking and unlocking based on the target user's position information. The electric assist bicycle automatically transitions between locking and unlocking states without requiring manual operation, achieving self-service functionality that eliminates the need for user interaction with lock mechanisms.
2Reliability
If mechanical or electronic locks are added to the electric assist bicycle, then the locking and unlocking function is achieved, but the cost increases
Solution Approach 1:
The patent replaces expensive mechanical locks and electronic locks with a positioning-based control system. By using the existing positioning functionality to determine locking states, the system eliminates the need for additional locking components, thereby reducing manufacturing costs while maintaining the locking function.
3Reliability
If mechanical or electronic locks are added to the electric assist bicycle, then the locking and unlocking function is achieved, but manual operation is required and automatic unlocking cannot be achieved
Solution Approach 1:
The system automatically controls locking and unlocking based on the target user's position information. When the user approaches or leaves the detection range, the system automatically transitions between unlocking and locking states without requiring any manual operation, achieving complete automation of the locking function.
4Extent of automation
If the electric assist bicycle uses positioning information for automatic locking and unlocking, then automatic control is achieved and manual operation is eliminated, but positioning accuracy may be affected by obstacles
Solution Approach 1:
The system establishes detection ranges and preset ranges in advance to determine when to transition between locking and unlocking states. By pre-defining these spatial parameters, the system can make automatic control decisions based on position information without requiring high-precision real-time positioning, thereby maintaining automation while being tolerant of positioning variations caused by obstacles.
