Smart Pet Door Dual-Locking Control for Selective Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart pet doors lack the ability to control unidirectional or bidirectional opening and closing, making it difficult for pet owners to manage pet access based on specific times or scenarios.
Innovation Solution
A smart pet door with a door lock mechanism featuring a motor-driven front and rear locking piece that can be positioned in four states to allow unidirectional inward or outward opening, bidirectional opening, or complete locking, controlled by a circuit board and power supply, with optional manual and remote operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a solenoid valve lock with bidirectional opening or locking states is used, then the door lock structure is simple, but the control flexibility for unidirectional opening is insufficient
Solution Approach 1:
The door lock mechanism is segmented into two independent locking pieces (front locking piece and rear locking piece) that can operate independently. Each locking piece can be controlled separately to achieve different door opening states, transforming a single bidirectional lock into a system with four distinct control states without requiring a completely new complex mechanism
Solution Approach 2:
The locking pieces are designed to be dynamically controllable through motor-driven rotation, allowing the system to transition between four different states (both locked, both unlocked, front locked only, rear locked only). This dynamic control capability provides adaptability for different scenarios while maintaining a relatively simple mechanical structure
2Adaptability or versatility
If a motor-driven dual locking piece mechanism is implemented, then the control flexibility for unidirectional and bidirectional opening is achieved, but the device complexity increases
Solution Approach 1:
A single motor is designed to drive both the front locking piece and the rear locking piece simultaneously through a shared transmission mechanism. This multi-functional design allows one motor to control multiple locking states, reducing the need for separate motors for each locking piece and thereby limiting the increase in device complexity
Solution Approach 2:
The transmission mechanisms for the front locking piece and rear locking piece are merged into a single integrated system. The motor's rotation is transmitted to both locking pieces through combined gears and transmission components, allowing synchronized or independent control while sharing common mechanical elements, thus controlling the overall complexity

AI summary
Disclosed is a smart pet door, including: a door frame, a door plate and a door lock. The door lock includes a motor, a front locking piece, a rear locking piece, a circuit main board and a power supply. The front and rear locking pieces are coaxially arranged and in transmission connection with the motor, the motor is electrically connected to the circuit main board, and the circuit main board is electrically connected to the power supply. The front locking piece is positioned on a front side of a lower edge of the door plate, the rear locking piece is positioned on a rear side of the lower edge of the door plate, and the motor drives the front and rear locking pieces to rotate. The front and rear locking pieces are able to abut against the door plate separately or simultaneously, or disengage from the door plate simultaneously.
