Wireless Charging Electronic Lock for Two-Wheelers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic security units for two-wheelers face challenges in providing a movable and removable design that can independently manage energy supply, as they often require regular charging and are susceptible to tampering due to numerous openings and parts.
Innovation Solution
The electronic security unit features a receiving body that holds and locks the base body, incorporating a wireless charging unit to charge the energy store when the base body is arranged on the receiving body, eliminating the need for connectors and interfaces, and utilizing electromagnetic coupling for energy transfer from a hub dynamo or motorcycle battery, along with a hermetically sealed design to prevent manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the security unit is designed with numerous openings, holes and individual parts to allow movement and removal, then the ease of operation is improved, but the susceptibility to tampering increases
Solution Approach 1:
The patent replaces mechanical connectors and charging interfaces with a wireless charging system using electromagnetic induction. The base body contains a transmitting coil that wirelessly transmits power to the receiving coil in the lock body, eliminating the need for physical charging ports and mechanical connectors that would create tampering vulnerabilities while maintaining operational functionality.
Solution Approach 2:
The base body is designed to serve multiple functions: it acts as both the mounting structure for the security unit and the wireless power transmission device. The receiving coil in the lock body serves dual purposes of wireless power reception and authentication verification, reducing the need for separate components and minimizing openings in the design.
2Ease of operation
If the energy store requires regular charging through connectors and interfaces, then the ease of charging is improved, but the number of openings and parts increases, making the system more susceptible to tampering
Solution Approach 1:
The patent replaces mechanical charging connectors with a wireless electromagnetic induction charging system. The transmitting coil in the base body and receiving coil in the lock body enable contactless power transfer, eliminating the need for physical charging ports, plugs, and associated mechanical interfaces that would increase device complexity and create security vulnerabilities.
Solution Approach 2:
The wireless electromagnetic field acts as an intermediary medium to transfer energy between the base body and lock body without direct physical contact. This intermediary mechanism enables power transfer while maintaining a sealed, tamper-resistant design with no openings required for charging connections.
3Reliability
If the security unit is firmly connected to the bicycle to prevent theft, then the reliability is improved, but the ability to prevent the bicycle from being carried away is reduced
Solution Approach 1:
The security unit is divided into two separable components: the base body that remains mounted on the bicycle frame, and the lock body that can be removed and carried. The base body contains the wireless transmitting coil and control electronics, while the lock body contains the receiving coil and locking mechanism. This segmentation allows the unit to provide both permanent mounting for theft prevention and removable functionality to prevent the entire bicycle from being carried away.
Solution Approach 2:
The wireless electromagnetic induction system enables the lock body to be securely attached to the base body during normal operation and then easily detached when needed, providing both stable connection for security and flexible removability for portability control, without requiring complex mechanical fastening systems.
