Smart Door Locking Handle With Deadbolt Alerts and Visitor Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door locking systems fail to adequately identify callers before granting access, posing safety risks, especially in emergency situations, and are vulnerable to fraud and identity theft due to insufficient verification methods.
Innovation Solution
A door locking device with an interior handle that activates a deadbolt, a controller for automatic alerts, a wireless communication module, and image capture devices to identify visitors, allowing for secure lockdown and verification of identities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a door locking system provides basic access control, then ease of operation is maintained, but security against emergencies and fraud is insufficient
Solution Approach 1:
The patent combines multiple security functions (deadbolt locking, alert signal generation, wireless communication, and image capture) into a single integrated door handle assembly. The controller unit within the handle coordinates all these functions, allowing the system to provide comprehensive security while maintaining a compact, unified structure that does not significantly increase overall device complexity.
Solution Approach 2:
The door handle assembly serves multiple functions: it acts as a mechanical locking mechanism, an alert signal generator, a wireless communication device, and an image capture station. This multi-functionality allows a single device to address various security concerns (emergencies, fraud, identification) without requiring separate systems for each function.
2Reliability
If automatic deadbolt engagement is added for emergency lockdown, then security in emergencies is improved, but device complexity increases
Solution Approach 1:
The automatic deadbolt engagement mechanism is integrated into the existing door handle assembly rather than being a separate system. The controller unit that manages alert signals also controls the deadbolt, consolidating control functions and reducing overall system complexity while providing automatic lockdown capability.
3Reliability
If image capture devices are integrated for visitor identification, then fraud prevention is improved, but device complexity and cost increase
Solution Approach 1:
The door handle assembly is designed to incorporate an image capture device as one of its multiple functions. The same controller unit that manages locking and alert functions also handles image capture and transmission, allowing the system to provide visitor identification and fraud prevention capabilities without requiring a separate verification system.

AI summary
A door locking device for a smart door apparatus (10) is provided comprising an interior door handle positionable on an interior side of a door; an exterior door handle positionable on an exterior side of the door (14); a lock for the door (14) which is coupled to the interior door handle, the lock having a deadbolt which is activatable by actuation of the interior door handle; a controller for automatically generating an alert signal in the event of activation of the deadbolt; and a wireless communication module associated with the controller, the wireless communication module automatically transmitting the alert signal in the event of activation of the deadbolt.
