Solution Overview

Problem

Existing vertical sliding gates are difficult to install and produce due to their complex and expensive construction, which makes them unsuitable for industrial production and widespread use, despite their potential for compact underground space occupation.

Innovation Solution

A compact gate design with a retractable casing that occupies less underground space when open, utilizing a motor and belt system for movement, along with a specially shaped casing and modular construction for simplified installation and transport, allowing for reduced installation time and costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a vertical sliding gate is designed to retract into the ground, then the occupied space when open is reduced, but the installation complexity and cost increase due to required underground structure

Engineering Contradiction:
Improveoccupied space when openVSAvoidinstallation complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The gate is divided into multiple horizontal slats that can move independently relative to each other. This segmentation allows the gate to compact into a smaller underground space while maintaining structural integrity, resolving the contradiction between reduced occupied space and installation complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The slats are designed to nest within each other when the gate is in the open position, with each slat containing or overlapping the next. This nesting mechanism enables the gate to occupy minimal underground space while preserving the vertical sliding functionality

Inventive Principle:
Principle #7Nested doll (Nesting)

2Strength

If a vertical sliding gate is constructed as a single solid structure, then structural strength is improved, but production and transport costs increase due to difficulty in industrial manufacturing

Engineering Contradiction:
Improvestructural strengthVSAvoidproduction cost
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The gate structure is segmented into multiple slats connected by hinges, allowing each component to be manufactured separately using standard industrial processes. This segmentation reduces production costs and facilitates mass production while maintaining overall structural strength through the interconnected design

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple individually manufactured slats are combined through hinged connections to form the complete gate structure. This merging of separately produced components achieves the required structural strength while benefiting from the cost efficiencies of modular industrial manufacturing

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If a vertical sliding gate requires a deep underground structure for installation, then the gate can retract fully, but the installation time and cost increase significantly

Engineering Contradiction:
Improveretraction functionalityVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The gate employs a dynamic sliding mechanism where slats move relative to each other along guided tracks, enabling full retraction into a shallow underground space. This dynamic design achieves reliable retraction functionality without requiring the deep static structure that would increase installation time

Inventive Principle:
Principle #15Dynamics
