Door Lock Deter Light Using Approach Detection and Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart lock systems lack the ability to provide individual access control and proactive deterrence for multiple doors within a space, failing to effectively discourage potential intruders before they attempt entry.
Innovation Solution
A door lock deter light system that includes an exterior door lock interface with an illumination device, equipped with sensors and processors to detect and identify unknown individuals, activating a deterrence state through illumination to discourage potential intruders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If smart locks are installed on each door to enable independent access control, then individual access control for multiple doors is achieved, but the system lacks the ability to proactively deter potential intruders before they attempt entry
Solution Approach 1:
The illumination device activates in a deterrence state before the door is actually locked or unlocked, serving as a preliminary action to discourage potential intruders from approaching or attempting entry. The sensor detects approach and triggers illumination before any locking mechanism engages, allowing prevention rather than just response.
Solution Approach 2:
The illumination device uses different illumination states (different colors or intensities) to convey different security conditions. A deterrence state illumination (e.g., red or bright white) signals potential intruders to leave, while a non-deterrence state (e.g., green or dim) indicates safe passage, using visual cues to communicate system status.
2Reliability
If traditional lock and key systems are used, then simplicity and reliability are maintained, but convenience and flexibility are lost
Solution Approach 1:
The smart lock interface combines multiple functions into a single device: traditional locking/unlocking capability, sensor-based detection of approaching individuals, and illumination-based deterrence. This multi-functional design maintains the reliability of traditional locks while adding the convenience of automatic detection and active deterrence without requiring separate systems.
3Reliability
If smart lock systems activate alarms upon intrusion attempts, then security response is provided, but proactive discouragement of potential intruders is not achieved
Solution Approach 1:
The illumination device provides preliminary anti-action by actively discouraging potential intruders before they can attempt intrusion. By illuminating in a deterrence state upon detecting approach, the system creates a preventive barrier that reduces the likelihood of intrusion attempts occurring in the first place, rather than merely responding after the fact.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances security by actively deterring unknown individuals at doors, providing an additional layer of protection beyond traditional smart lock systems.
Implementation Method 1
sensing that a person approaches a door
Implementation Method 2
activating the illumination device on the exterior door lock interface to be in a deterrence state

AI summary
Systems and methods for deterring a person at a door using a door lock deter light are disclosed. One method of deterring an unknown person at a door includes sensing that a person approaches a door at which an exterior door lock interface including an illumination device is located. The method further includes determining whether the person is unknown and, in response to determining that the person is unknown, activating the illumination device on the exterior door lock interface to be in a deterrence state. Otherwise, the method further includes activating the illumination device to be in a non-deterrence state or maintaining the illumination device in a deactivated state.
