Solution Overview

Problem

French doors, with their significant glass surface area, cannot accommodate traditional pet doors, necessitating owners to leave doors open, which is impractical and exposes pets to adverse weather conditions.

Innovation Solution

A panel insert for French doors that includes a window and pet door component, allowing pets to enter and exit without human intervention, featuring a movable flap and locking mechanisms for security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional pet doors are installed in French doors, then pets can enter and exit independently, but the significant glass surface area of French doors prevents accommodation of traditional pet doors

Engineering Contradiction:
ImproveIndependent pet entry and exitVSAvoidCompatibility with French door structure
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent applies nesting by placing a pet door component inside a panel insert, which itself is installed within the French door's glass opening. The pet door is nested within the insert structure, allowing the pet door functionality to be accommodated within the constraints of the French door's glass surface area without requiring external modifications to the door structure.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent segments the solution into distinct components: a panel insert that fits within the French door opening and a pet door component that fits within the insert. This segmentation allows each component to be optimized independently - the insert adapts to the French door structure while the pet door component provides the required functionality, resolving the conflict between structural compatibility and operational capability.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If French door owners leave doors open to accommodate pets, then pets can enter and exit freely, but pets are exposed to adverse weather conditions and indoor accidents occur more frequently

Engineering Contradiction:
ImproveFree pet movementVSAvoidWeather exposure and indoor accidents
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent implements self-service by enabling the pet to independently operate the pet door component within the panel insert. The pet can push the flap or activate the opening mechanism without human assistance, allowing free movement while the door remains closed, thereby protecting against weather exposure and preventing indoor accidents while maintaining operational convenience.

Inventive Principle:
Principle #25Self-service
