Inflatable Impact Shield for Earthquake Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional impact mitigation technologies are not lightweight, portable, or cost-effective, often requiring affixation to a specific location and failing to provide sufficient protection from earthquake damage due to lack of rigidity and high costs, making them impractical for widespread use in seismic areas.
Innovation Solution
A portable, inexpensive impact shield system with an inflatable semispherical canopy and structural column made of puncture-resistant material, incorporating individual spar segments for enhanced rigidity and a seismic detection device for automatic inflation, designed for compact storage and rapid deployment in emergency situations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If conventional impact mitigation technologies are used, then protection from earthquake damage is provided, but the systems are heavy, non-portable, and require affixation to a specific location
Solution Approach 1:
The impact shield transitions from a static, fixed structure to a dynamic, movable system. The inflatable structure can be deployed and relocated as needed, providing protection without requiring permanent affixation to a specific location. The structure inflates to its protective form only when needed, combining mobility with effectiveness.
Solution Approach 2:
The structure changes its physical state from a compact, deflated configuration to an inflated, rigid protective shell. This parameter change allows the same structure to be both portable (when deflated) and effective (when inflated), resolving the contradiction between weight/portability and protection effectiveness.
2Strength
If conventional impact mitigation technologies are used, then some protection is provided, but the systems lack sufficient rigidity to withstand structural collapse
Solution Approach 1:
The impact shield employs a spherical or dome-shaped structure, which is inherently stronger and more rigid than flat or angular designs of the same material thickness. The curved geometry distributes forces evenly across the surface, providing enhanced rigidity and protection against structural collapse without requiring excessively complex internal bracing.
Solution Approach 2:
The shield uses composite construction with an outer shell, internal support structure, and inflatable elements working together. This composite approach achieves the necessary rigidity through the combination of different structural components rather than relying on a single complex element.
3Ease of manufacture
If conventional impact mitigation technologies are used, then protection systems are provided, but the costs are prohibitively high for widespread distribution
Solution Approach 1:
The impact shield uses thin-walled inflatable structures rather than thick, rigid materials. This approach dramatically reduces material costs and manufacturing complexity while maintaining protection effectiveness through the inflated air pressure that provides structural strength. The flexible shell design is much more cost-effective for widespread distribution.
Solution Approach 2:
The system uses pneumatic inflation to create structural strength without requiring heavy, expensive materials. The pressurized air acts as a structural element, providing rigidity and protection at a fraction of the cost of traditional solid structures, enabling widespread distribution.
4Volume of moving object
If the impact shield is designed for portability and compact storage, then widespread distribution is enabled, but the structure may lack the rigidity needed for earthquake protection
Solution Approach 1:
The structure dynamically changes between a compact, low-volume stored state and a large, rigid protective state. When deflated, it occupies minimal space for easy storage and transport. When inflated, it expands to provide the necessary structural rigidity and volume for earthquake protection, resolving the contradiction between storage compactness and protective strength.

AI summary
An impact shield for earthquake protection is described herein. The impact shield may include a canopy constructed of a puncture-resistant material, the canopy defining a first internal volume accessible via a first opening, the canopy being structured to form a semispherical shape when in an inflated state, the semispherical shape defining a space dimensioned for sheltering at least one human body; a support joined to the canopy and constructed of the puncture-resistant material, the support defining a second internal volume accessible via the first opening and a second opening, the support located within the space, the support structured to form a column when in the inflated state; and a fitting joined to the support for closing the second opening to fix the first internal volume and the second internal volume after inflation of the support and the canopy.
