Solution Overview

Problem

Conventional barrier hinge assemblies are prone to disconnection upon bumping or lifting, are inconvenient to operate, and fail to securely hold barrier segments due to easily breakable teeth and a weak spring mechanism, leading to loose or collapsed barriers over time.

Innovation Solution

A barrier hinge assembly comprising an upper and lower hinge assembly with a turnbuckle assembly that securely holds adjacent barrier segments by threading onto the pintles of the upper and lower pintle devices, allowing for adjustable and foldable barriers while maintaining firm positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional teeth and spring mechanism are used to hold barrier segments, then the barrier can be assembled, but the teeth break easily and the spring cannot hold the barrier segments firmly, leading to disconnection upon bumping or lifting

Engineering Contradiction:
Improveconnection stabilityVSAvoidteeth strength
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

The patent removes the conventional teeth mechanism from the hinge assembly. Instead of using teeth that engage and disengage, the invention uses a pin that passes through holes in the gudgeon and pintle devices, eliminating the teeth entirely and replacing them with a simpler, more reliable pin connection that cannot break or wear down

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The spring is pre-loaded during assembly to immediately engage the pin with the gudgeon and pintle devices. The spring is positioned to exert continuous force that maintains the pin in its engaged state, ensuring the barrier segments are held firmly from the moment of assembly without requiring ongoing adjustment

Inventive Principle:
Principle #10Preliminary action

2Device complexity

If the barrier hinge assembly uses a simple pin and spring mechanism, then the structure is simplified, but the barrier segments cannot be held firmly and may disconnect easily

Engineering Contradiction:
Improvehinge assembly structureVSAvoidposition holding capability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The hinge assembly is divided into distinct functional components: the pin for connection, the spring for force application, the gudgeon device with through-hole for the pin, and the pintle device with recess for the pin. This segmentation allows each component to perform its specific function efficiently while maintaining overall simplicity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The spring acts as an intermediary element between the pin and the barrier segments. It transmits continuous holding force through the pin to secure the gudgeon and pintle devices, providing the necessary reliability without adding complex mechanical features

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If the conventional hinge assembly allows easy disengagement of teeth, then adjustment is possible, but the barrier segments disconnect easily upon bumping or lifting

Engineering Contradiction:
Improveadjustment convenienceVSAvoidconnection stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The pin connection maintains a dynamic state where the spring continuously exerts force to keep the pin engaged with the gudgeon and pintle devices. This dynamic engagement allows the barrier to be adjusted when needed while maintaining firm connection during normal use, resolving the contradiction between ease of operation and connection stability

Inventive Principle:
Principle #15Dynamics

AI summary

A barrier hinge assembly has an upper hinge assembly, a lower hinge assembly and a turnbuckle assembly. The upper hinge assembly has an upper pintle device and an upper gudgeon device. The upper pintle device has a pintle protruding down. The upper gudgeon device has a through hole in which the upper pintle is mounted. The lower hinge assembly has a lower gudgeon device and a lower pintle device. The lower gudgeon device has a through hole. The lower pintle device has a pintle protruding up and mounted through the through hole of the lower gudgeon device. The turnbuckle assembly is fastened to the pintles of the upper and the lower pintle devices at the same time to hold the upper and the lower gudgeon devices in specific positions.
