Solution Overview

Problem

Existing vehicle pet barriers face issues such as high cost, heavy weight, large size, difficult installation and uninstallation, sagging, and visibility problems due to large hole sizes in netting materials, which affect their practicality and driver distraction.

Innovation Solution

A net pet barrier featuring netting material fastened to a metal wire hoop that folds into three concentric circles, with expansion panels and grommet strips for adjustment and easy storage, utilizing a combination of fasteners and adhesive-backed reclosable fasteners for secure installation and quick removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If metal tubing barriers with compression rods are used, then structural strength is improved, but weight and cost increase

Engineering Contradiction:

Improvestructural strengthVSAvoidweight

Core Design Contradiction:

StrengthVSWeight of moving object

Solution Approach 1:

The patent replaces rigid metal tubing with a flexible wire frame structure that maintains structural integrity while significantly reducing weight. The wire frame is covered with netting material that provides the necessary barrier function without the heavy metal construction, achieving both strength and weight reduction.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The barrier is designed to be collapsible and foldable, transforming from a rigid static structure to a dynamic flexible one. The wire frame can be compressed into a compact configuration for storage and transport, then expanded to full size for use, providing structural strength when needed while minimizing weight and space during storage.

Inventive Principle:

Principle #15Dynamics

2Ease of manufacture

If netting material with large hole size is used, then manufacturing cost is reduced, but driver distraction increases

Engineering Contradiction:

Improvemanufacturing costVSAvoiddriver distraction

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent applies different netting configurations in different areas. The central portion uses larger mesh for cost-effectiveness, while the perimeter uses a wire frame border that provides structural definition and reduces the visual pattern effect. This localized differentiation maintains manufacturing efficiency while reducing driver distraction at critical viewing areas.

Inventive Principle:

Principle #3Local quality

3Ease of manufacture

If netting material is used without wire frame, then manufacturing cost is reduced, but sagging occurs

Engineering Contradiction:

Improvemanufacturing costVSAvoidsagging

Core Design Contradiction:

Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The patent uses a flexible wire frame structure that provides structural support to the netting material. The wire frame acts as a tensioning element that keeps the netting taut and prevents sagging, while the overall structure remains flexible and collapsible for storage. This approach maintains manufacturing simplicity while eliminating the sagging problem.

Inventive Principle:

Principle #30Flexible shells and thin films

4Adaptability or versatility

If barrier is designed for multiple vehicle sizes, then adaptability is improved, but device complexity increases

Engineering Contradiction:

Improveadaptability to various vehiclesVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent employs a dynamic, collapsible wire frame structure that can be compressed to different sizes and configurations. This allows a single barrier design to adapt to various vehicle dimensions without requiring multiple fixed-size models. The frame can be expanded to fit larger vehicles or compressed for smaller vehicles, maintaining simplicity while achieving versatility.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The barrier is divided into modular sections including the wire frame, netting material, and collapsible panels. These segmented components can be independently adjusted and reconfigured to fit different vehicle sizes, reducing the need for complex integrated designs while maintaining adaptability across multiple vehicle types.

Inventive Principle:

Principle #1Segmentation

5Volume of moving object

If barrier is made collapsible for storage, then storage space is reduced, but installation complexity increases

Engineering Contradiction:

Improvestorage spaceVSAvoidinstallation complexity

Core Design Contradiction:

Volume of moving objectVSDevice complexity

Solution Approach 1:

The collapsible wire frame structure is designed to naturally spring into its expanded configuration during installation, reducing the complexity of assembly. The dynamic structure allows for easy collapse into a compact bundle for storage, then automatically expands when installed, providing both space efficiency and installation simplicity without requiring complex mechanisms.

Inventive Principle:

Principle #15Dynamics

AI summary

A net pet barrier designed for installation behind the front or rear seat in a vehicle to keep pets off vehicle seats and in the back of the vehicle. Netting formed of micro-mesh material is attached to a pop-up wire frame which keeps the net from sagging and facilitates installation and removal. Adjustable side expansion panels allow installation of the barrier in vehicles of various sizes and configurations, from sedans to full-size SUVs.
