Portable Lock Wireless Authentication Energy Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable locks lack convenience and security, as they often require physical keys that can be lost or stolen, and do not offer efficient authentication methods for authorized users.
Innovation Solution
An electronic portable lock with an unlocking motor and authentication module that uses wireless authentication via Bluetooth, eliminating the need for physical keys and incorporating an actuation element for intuitive operation, along with energy-saving features to conserve power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If wireless authentication is performed continuously in alert state, then authentication speed and user convenience are improved, but energy consumption increases excessively
Solution Approach 1:
The authentication module performs preliminary actions by pre-authenticating users before the actual unlocking operation. The system maintains a ready state where authentication data is pre-loaded and processed, so that when the actuation element is triggered, the authentication can be completed immediately without time delay. This preliminary preparation resolves the contradiction by having the system ready in advance rather than processing everything in real-time.
Solution Approach 2:
The authentication module operates periodically rather than continuously - it switches between active authentication states and low-power sleep states. The module is activated periodically to check for authentication requests, processes authentication data in batches, and then returns to a low-power state. This periodic operation significantly reduces energy consumption while maintaining acceptable authentication response times.
2Productivity
If the authentication module is kept in alert state for early authentication, then unlocking speed is improved, but the energy store may not deliver sufficient energy to the closing motor
Solution Approach 1:
The system performs preliminary authentication processing in advance, storing authentication results and user data in memory before the actual unlocking operation. When the actuation element is triggered, the system uses the pre-processed authentication data to immediately authorize unlocking, eliminating the need for continuous authentication processing. This preliminary action ensures both fast unlocking and sufficient energy availability for the closing motor.
Solution Approach 2:
The authentication module dynamically adjusts its power consumption based on system state - it operates at full power only when authentication is needed, then transitions to low-power or sleep mode. The system intelligently manages power states, activating the authentication module only when a user approaches or triggers the actuation element, and deactivating it afterward. This dynamic power management ensures energy is available for the closing motor while maintaining unlocking speed.
Data Source
AI summary
The disclosure relates to a portable lock having an unlocking motor, an authentication for authenticating the user of the lock, and an actuation element that can be actuated by the user to activate the unlocking motor to unlock the lock after a successful authentication of the user. A further subject matter is a locking system having such a lock and a mobile end device to allow a user of the lock to authenticate himself thereat. The disclosure also relates to a method of unlocking a mobile lock.
