Protective Structure With Crushing Mesh And Absorbing Bottom Layer

Solution Overview

Problem

Existing protective structures are inadequate for withstanding and mitigating the impact of heavy, hot, or propelled falling objects, as they often fail to stop or protect against severe damage from descending items, especially in strategic areas.

Innovation Solution

A protective structure comprising an upper mesh layer made of hard material for crushing descending items and a bottom layer of combined hard and soft materials for absorption, with supporting poles and a non-horizontal mesh configuration to enhance effectiveness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional shields are used to protect against falling objects, then basic protection is provided, but they fail to stop heavy, hot, or propelled objects

Engineering Contradiction:

Improveprotection effectivenessVSAvoidimpact resistance

Core Design Contradiction:

ReliabilityVSStrength

Solution Approach 1:

The protective structure is divided into multiple functional layers: an upper mesh layer for crushing objects, a middle layer with supporting poles for energy absorption and distribution, and a bottom layer for final impact absorption. This segmentation allows each layer to specialize in a specific aspect of impact mitigation, enabling the structure to stop heavy, hot, or propelled objects that traditional single-layer shields cannot withstand.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The structure employs composite material construction with the upper mesh layer made of hard material for crushing, the supporting poles made of tubes filled with concrete or reinforced concrete, and the bottom layer made of combined hard and soft materials. This composite approach combines the strengths of different materials to achieve both high impact resistance and effective energy absorption, resolving the contradiction between protection reliability and impact strength.
