Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing pet doors lack the ability to provide secure and controlled access for pets while preventing intruders and offering environmental protection, often relying on human intervention and failing to maintain weather integrity.

Innovation Solution

A pet access control system with a door unit mounted on a frame, equipped with a locking mechanism and actuator, which operates based on signals from pet tags, allowing authorized pets to enter or exit while blocking unauthorized access and enhancing weather resistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional pet door is installed to allow pets to enter and exit freely, then pet convenience is improved, but security against intruders and control over access timing deteriorates

Engineering Contradiction:

Improvepet convenienceVSAvoidsecurity control

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system enables pets to automatically open the door using RFID tags embedded in their collars, eliminating the need for human intervention while maintaining security through automated identification and authentication mechanisms

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces traditional mechanical pet door flaps with an automated motorized door system controlled by RFID recognition, allowing for precise control over door operation timing and access authorization

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If a pet door is installed to provide unlimited access, then pet freedom of movement is improved, but the ability to control access based on owner's wishes deteriorates

Engineering Contradiction:

Improveaccess control flexibilityVSAvoidhuman intervention requirement

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system dynamically adjusts door access control based on time-of-day settings and owner preferences, allowing the door to be locked during specific periods (e.g., when workers are present) and unlocked at other times without requiring manual intervention

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The control system receives feedback from RFID tag recognition and time-based sensors to automatically adjust door operation, providing adaptive access control that responds to environmental conditions and scheduled parameters

Inventive Principle:

Principle #23Feedback

3Ease of manufacture

If a simple pet door flap is used to maintain weather integrity, then installation simplicity is improved, but weather protection effectiveness deteriorates

Engineering Contradiction:

Improveinstallation simplicityVSAvoidweather protection

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent replaces simple flexible flaps with a motorized door system that can fully close and seal against the door frame, providing superior weather protection while maintaining relatively simple installation through integration with existing door structures

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
