Interchangeable Pet Door With Latch And Hinge Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pet doors are difficult to install, secure, and customize, often allowing dirt to be tracked into homes and not fully closing, which can lead to security and maintenance issues, and are typically manually operated, making them hard for pets to use safely.
Innovation Solution
A customizable and securable pet door system that includes a door with a knob, hinge, and windows, allowing for secure locking and semi-automatic operation via sensors, enabling pets to use the door independently while maintaining home aesthetics and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pet door is installed to allow pets to navigate within and into or out of homes, then pet access control is improved, but security and dirt tracking worsen because the door cannot be completely closed or secured
Solution Approach 1:
The pet door system is divided into separate functional components: a frame assembly that integrates with the door, a pet door assembly with movable flaps, and a securing mechanism with latch and button. This segmentation allows the pet door to provide access control while the frame and securing mechanisms independently maintain security and closure capabilities.
Solution Approach 2:
The pet door assembly is nested within the frame assembly, with the pet door flaps positioned inside the frame structure. The securing mechanism components (latch, button, spring) are nested within the frame assembly. This nesting allows the pet door functionality to be contained while maintaining the structural integrity and security of the overall door system.
2Ease of manufacture
If a pet door is designed to be manually operated, then ease of installation is improved, but pet safety and ease of use worsen when the door gets stuck or breaks
Solution Approach 1:
The pet door flaps are designed as movable dynamic elements that can automatically open and close in response to pet interaction. The spring-loaded latch mechanism provides dynamic securing that automatically engages and disengages. This dynamic design allows the door to adapt to pet usage while maintaining security, reducing the need for manual intervention.
Solution Approach 2:
The pet door flaps enable pets to independently open and close the door through their own actions (pushing or pulling the flaps). The spring-loaded latch automatically secures the door when closed without requiring manual locking. This self-service capability improves pet safety by eliminating the need for pets to manipulate complex manual mechanisms.
3Adaptability or versatility
If a pet door allows incremental opening like a Dutch door, then visibility and control are improved, but structural complexity and manufacturing difficulty worsen
Solution Approach 1:
The pet door assembly is segmented into multiple independent flaps (first flap and second flap) that can move independently. This segmentation allows incremental opening where pets can push one flap while the other remains closed, providing visibility and control without requiring a complex multi-section door structure like a Dutch door.

AI summary
An interchangeable pet door is disclosed. The interchangeable pet door comprises a door, a knob, a plurality of windows, a frame, and a hinge. The knob comprises a latch for securely closing the door. When the interchangeable pet door comprises a hinge, inserting the hinge into a hinge recess securely locks the door. The different elements of the interchangeable pet door are configured to be oriented in a predetermined, interchangeable, or customizable manner. The door is configured to open from, slide into, revolve within, or move in some other non-limiting equivalent way from or relative to a frame.
