Locking Device Multiple Authentication Methods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic locksets require a mobile device or key fob for access, posing a problem when these devices are unavailable, as users cannot unlock or lock doors without them.
Innovation Solution
An auxiliary authentication input device with a keypad and wireless communication unit is integrated into the lockset, allowing users to input authentication codes without needing a phone or key fob, using a controller to electronically control the lock's mechanical assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electronic locksets use wireless communication with mobile devices or key fobs for authentication, then security is improved, but usability deteriorates when the user does not have these devices
Solution Approach 1:
The lockset system is designed to support multiple authentication methods including wireless communication with mobile devices/key fobs and direct keypad input. This multi-functionality ensures that users can access the door through various means, maintaining security while improving accessibility when primary devices are unavailable.
Solution Approach 2:
The keypad serves as an intermediary authentication device that allows direct input of authentication codes without requiring mobile devices or key fobs. This intermediary mechanism bridges the gap between wireless authentication and manual input, ensuring continuous access capability.
2Reliability
If electronic locksets require mobile devices or key fobs for authentication, then security is enhanced, but device complexity increases
Solution Approach 1:
The controller is designed to handle multiple authentication protocols including wireless communication and direct keypad input. By integrating these functions into a single controller, the system achieves enhanced security through multiple authentication methods while avoiding the need for separate complex subsystems.
3Ease of operation
If electronic locksets provide keyless operation with mobile devices, then ease of operation is improved, but reliability deteriorates when devices are unavailable
Solution Approach 1:
The system allows dynamic switching between different authentication modes (wireless vs. keypad) based on availability. When mobile devices are unavailable, the authentication parameter changes from wireless communication to direct keypad input, maintaining access reliability while preserving the keyless convenience where applicable.

AI summary
A locking device with a bolt movable between a locked position and an unlocked position. The locking device includes an electronic controller for selectively controlling movement of the bolt between the locked and unlocked position. At least two input devices are provided, such as a keypad, a biometric input, etc., which communicate an authentication code to the controller. The controller controls movement of the bolt based on a valid authentication code received from any of the at least two input devices.
