Proximity Sensor Doorbell and Remote Lock Control System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional access control systems are limited by requiring homeowners to be present to control access, are inoperable if the homeowner forgets their key or access card, and can fail due to frequent or excessive button pressing.
Innovation Solution
A remote access control system comprising a remote host connected to a mobile device via the Internet, a proximity sensor doorbell, a camera-equipped gateway device, and a door lock device, allowing remote control and contactless doorbell triggering, with the gateway device sending notifications and controlling the door lock via the mobile device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the householder is inside the house to control the access control system, then the door can be controlled to open, but the householder cannot control the system when leaving the house
Solution Approach 1:
The patent introduces a remote host and mobile device as intermediaries between the householder and the access control system. The gateway device communicates with the remote host via the Internet, enabling the householder to control the door lock remotely through a mobile device, thus resolving the limitation of requiring physical presence inside the house.
Solution Approach 2:
The patent extends the control capability from local (inside the house) to remote (anywhere via Internet) by adding the network communication dimension. The gateway device connects to the Internet through a network unit, enabling control operations to be performed from any location with network access.
2Ease of operation
If the electronic button is pressed frequently or with excessive force to trigger the doorbell, then the doorbell can be activated, but the doorbell would fail and be unable to trigger
Solution Approach 1:
The patent replaces the mechanical button-pressing system with a proximity sensor-based detection system. The proximity sensor doorbell detects the visitor's approach through non-contact sensing, eliminating the need for physical button pressing and thereby preventing mechanical failure from frequent or excessive pressing.
Solution Approach 2:
The proximity sensor acts as an intermediary between the visitor and the doorbell triggering mechanism. Instead of direct mechanical contact, the sensor detects the visitor's presence and triggers the doorbell signal, reducing wear and failure risk on the triggering mechanism.
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
Enables remote control of the entry system, reduces the likelihood of doorbell failure, and provides a secure, convenient access solution by allowing homeowners to control access from anywhere and preventing damage from excessive button pressing.
Implementation Method 1

AI summary
A remote access control system comprising a remote host connected to a mobile device, a proximity sensor doorbell, a door lock device and a gateway device is provided. The proximity sensor doorbell triggers a doorbell signal when sensing a finger of a visitor approaches. The gateway device sends a first notification message to the mobile device via the remote host when recognizing that a captured monitoring video comprises image of the visitor, sends a second notification message to the mobile device via the remote host when receiving the doorbell signal, and controls the door lock device to unlock when receiving an unlocking message from the mobile device. This system facilitates the householder to control the entry remotely and effectively reduces the probability of doorbell failing.
