Solution Overview

Problem

Traditional fence gates for children and pets are bulky, occupying significant space during transportation and have inefficient assembly processes due to their disassembly into numerous parts.

Innovation Solution

A barrier system with modular assembly modules, including a first and second door leaf subassembly modules and a first and second frame subassembly modules that are rotatably connected, allowing for separation and detachment, enabling compact shipping and efficient assembly without tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the barrier system is disassembled into a plurality of parts and components for packaging and transportation, then the transportation space is reduced, but the assembly process becomes inefficient and inconvenient due to the large number of parts

Engineering Contradiction:
Improvetransportation spaceVSAvoidassembly efficiency
Core Design Contradiction:
Volume of moving objectVSProductivity

Solution Approach 1:

The barrier system is divided into multiple independent fence modules, each comprising a frame assembly and a gate assembly. This segmentation allows compact packaging while maintaining assembly efficiency through standardized interfaces between modules.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The gate assembly is rotatably connected to the frame assembly within the same module, allowing the gate to be nested within the frame structure during storage and transportation, reducing overall volume without requiring separate packaging for each component.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If the barrier system is designed as a single integrated structure, then the assembly process is simplified, but the transportation space occupation increases significantly

Engineering Contradiction:
Improveassembly simplicityVSAvoidtransportation space
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The barrier system is divided into multiple independent fence modules, each comprising a frame assembly and a gate assembly. This segmentation allows compact packaging while maintaining assembly simplicity through standardized interfaces between modules.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each fence module is pre-assembled with the gate rotatably connected to the frame during manufacturing, so that upon delivery, the modules can be quickly installed by connecting frame assemblies together without requiring on-site assembly of individual components.

Inventive Principle:
Principle #10Preliminary action

AI summary

A barrier system that occupies less space in transportation and reduces the identification and matching time of parts for assembly to improve assembly efficiency. The barrier system includes a door leaf and a frame with a first, second, and third assembly modules. The first assembly module includes a first door leaf subassembly module and a first frame subassembly module that are rotatably connected. The second assembly module includes a second door leaf subassembly module that may be detachably connected with the first door leaf subassembly module to form a door leaf. The third assembly module includes a second frame subassembly module detachably connected with the first frame subassembly module to form a frame. The first, second, and third assembly module are independent of each other when they are not assembled, and together form a barrier system after assembly.
