Solution Overview

Problem

Existing multi-part crash resistant gates face challenges in creating a strong, impact-resistant connection between their components, which can become weaker spots when subjected to vehicle impacts, especially for longer gates that require exceptional transportation methods due to standard steel profile limitations.

Innovation Solution

A multi-part crash resistant gate design featuring slidably movable gate parts with reinforcement beams that extend over the length of the gate, using H steel or HEB beam profiles, and connected via bolts and connection plates to form a robust and aligned structure, ensuring the connection remains secure under impact forces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If gate parts are divided into multiple sections for transportation, then ease of transportation is improved, but connection strength deteriorates

Engineering Contradiction:
Improveease of transportationVSAvoidconnection strength
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The gate is divided into multiple gate parts (first gate part and second gate part) that can be transported separately. Each gate part contains reinforcement beams that are crash-resistant coupled to form a continuous reinforcement structure when assembled, maintaining strength while enabling separate transportation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The reinforcement beams from adjacent gate parts are crash-resistant coupled together to form a continuous reinforcement beam that extends over the entire gate length. This merging of reinforcement structures ensures that the connection between gate parts maintains crash-resistant strength comparable to the gate parts themselves.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If gate parts are connected using conventional methods, then ease of assembly is improved, but crash resistance deteriorates

Engineering Contradiction:
Improveease of assemblyVSAvoidcrash resistance
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The reinforcement beams are designed with predetermined coupling features that enable crash-resistant connections. The reinforcement beams extend into the hollow beams of adjacent gate parts and are coupled using connection plates and bolts, creating a pre-engineered crash-resistant joint that maintains structural integrity under impact forces.

Inventive Principle:
Principle #10Preliminary action

3Stability of the object's composition

If gate length is increased to reduce number of connections, then structural integrity is improved, but transportation difficulty worsens

Engineering Contradiction:
Improvestructural integrityVSAvoidtransportation difficulty
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The gate is segmented into multiple transportable gate parts, each containing reinforcement beams that are designed to be crash-resistant coupled together. This segmentation enables transportation of individual parts while maintaining overall structural integrity through the continuous reinforcement beam formed by coupling adjacent parts.

Inventive Principle:
Principle #1Segmentation
