Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blast-resistant waste containers are either large, complicated, difficult to install, or heavy, and lack effective solutions for absorbing and redirecting the force of explosions without causing collateral damage.
Innovation Solution
A blast-resistant barrier and container design featuring a rigid inner and outer layer with compressed pumice brick layers, which absorb and redirect blast forces, combined with a steel cable reinforced belt and corrugated material to manage pressure waves and prevent horizontal blast pressure from injuring bystanders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional blast-resistant containers use heavy reinforced materials like steel shells with concrete filling, then blast resistance is improved, but weight and installation difficulty increase significantly
Solution Approach 1:
The patent uses a composite structure combining rigid outer and inner layers with compressible pumice brick material in between. This composite approach provides blast resistance through the rigid layers while the pumice brick absorbs energy, achieving protection without the excessive weight of solid concrete or steel constructions.
Solution Approach 2:
The patent employs pumice brick, a porous material, as the core blast-absorbing layer. The porous structure allows the material to compress and expand during blast events, absorbing energy effectively while maintaining a lightweight profile compared to dense reinforced concrete alternatives.
2Strength
If blast-resistant containers use complex multi-layer structures with reinforced materials, then explosion force absorption is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The container uses a straightforward composite structure with three main layers: rigid outer layer, pumice brick intermediate layer, and rigid inner layer. This simple composite design achieves effective blast force absorption without the complexity of multiple specialized layers or intricate reinforcement patterns found in conventional designs.
3Object-affected harmful factors
If blast-resistant containers redirect explosion forces, then protection of bystanders is improved, but structural integrity requirements and manufacturing complexity increase
Solution Approach 1:
The container is divided into modular components - outer layer, pumice brick layer, and inner layer - that can be manufactured separately and assembled. This segmentation allows for easier fabrication and installation while the layered structure naturally facilitates blast pressure redirection through its geometric configuration.
