Automated Pet Entry Authentication with Proximity and Sensor Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pet entry systems face challenges such as difficulty in training pets to use flap doors, unauthorized access by wild animals, inaccurate detection of pet presence, and frequent false positives due to proximity-based authentication, especially in residential environments.
Innovation Solution
A pet entry system that uses a wireless key signal from a tag, validates the signal's proximity and authenticity, and controls door access through a door controller, ensuring the pet is within a predetermined range and proximity for valid authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If proximity-based wireless key authentication is used, then pet entry convenience is improved, but false positive detection increases causing unauthorized door opening
Solution Approach 1:
The authentication process is divided into two independent stages: proximity detection (first stage) and intentional action verification (second stage). The trigger device first detects if the pet is within proximity using wireless key signal, then separately verifies intentional door-opening action through sensor activation. Only when both stages are satisfied does the door open, preventing false positives from accidental proximity detection.
Solution Approach 2:
The trigger device acts as an intermediary between the pet and the door controller. It receives wireless key signals from the pet tag, validates proximity, detects intentional activation through sensors (button press, touch, motion, or weight), and only then sends the door opening command to the door controller. This intermediary layer adds verification steps that prevent unauthorized opening while maintaining convenience for legitimate pets.
2Adaptability or versatility
If simple flap doors are used, then pet access freedom is improved, but unauthorized access by wild animals increases
Solution Approach 1:
The traditional mechanical flap door system is replaced with an automated electronic system. The trigger device uses wireless key detection (electromagnetic field) to identify authorized pets, and sensor technology (electrical/optical) to verify intentional action. The door controller electronically manages the door opening mechanism, replacing the simple mechanical push-flap system with a multi-layer authenticated control system that prevents wild animal access while maintaining pet freedom.
3Speed
If proximity detection alone is used, then response speed is improved, but measurement precision deteriorates causing false triggers
Solution Approach 1:
The trigger device performs preliminary proximity detection using wireless key signal to determine if a pet is near the door. This preliminary action quickly identifies potential candidates for door opening. However, this is followed by a second verification step detecting intentional action (button press, touch, motion, or weight) before the door actually opens. This two-stage preliminary verification maintains fast response for legitimate pets while preventing false triggers from accidental proximity.

AI summary
A pet entry system and process including determining if a sensor or button has been triggered or activated; activating or waking at least one processor if at least one sensor or button has been triggered or activated; scanning for a wireless key signal; receiving a wireless key signal from a tag; validating or authenticating the wireless key signal received from the tag; evaluating a distance of the tag to the wireless key receiver if the received wireless key signal is valid; confirming if the distance of the tag is within a predetermined distance or proximity range and the wireless key signal is valid; sending a door open to a door controller if the tag is within the predetermined distance or proximity range; and ending the scanning for wireless key signal.
