Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blast protection systems for buildings are ineffective as they block ventilation and light, have an unappealing aesthetic, and are cumbersome, while also being prone to damage from pressure waves, and fail to prevent debris from causing injury.
Innovation Solution
A blast screen system featuring a flexible architectural mesh panel secured by spring-biased brackets, allowing for ventilation and light passage while providing structural integrity and debris containment, using stainless steel components and adjustable mesh configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If solid barriers are used to block debris from explosions, then protection from debris is improved, but ventilation and light passage deteriorate
Solution Approach 1:
The patent employs a mesh screen with controlled porosity that allows light and ventilation to pass through while intercepting debris. The mesh structure provides open areas for light transmission but maintains sufficient density to trap explosive debris, resolving the contradiction between protection and illumination.
Solution Approach 2:
The system combines the mesh screen with spring-biased mounting brackets to create a composite protective system. The mesh provides debris filtration while the spring mechanism provides dynamic response to pressure waves, achieving both protection and environmental compatibility.
2Reliability
If solid barriers are used to block debris from explosions, then protection from debris is improved, but aesthetic appearance deteriorates
Solution Approach 1:
The mesh screen's porous structure allows for aesthetically pleasing designs that maintain protective function. The open pattern enables light transmission and visual appeal while the mesh density provides adequate debris protection, avoiding the ugly appearance of solid barriers.
3Reliability
If solid barriers are used to block debris from explosions, then protection from debris is improved, but the barrier is damaged by overwhelming pressure waves
Solution Approach 1:
The spring-biased mounting system transforms the static barrier into a dynamic structure. During explosion, the spring mechanism allows the mesh to deform and move with the pressure wave, absorbing energy and preventing structural damage while maintaining debris protection capability.
Solution Approach 2:
The mesh screen acts as a flexible protective layer that can deform under pressure wave loading. This flexibility allows the system to withstand overwhelming pressure waves without rigid failure, while the mesh structure maintains its debris-trapping function.
4Illumination intensity
If mesh screens are used to allow ventilation and light passage, then ventilation and aesthetics are improved, but debris containment capability deteriorates
Solution Approach 1:
The mesh screen utilizes controlled porosity to balance light transmission and debris containment. The specific mesh density and pattern allow sufficient light and ventilation passage while maintaining adequate debris interception, resolving the contradiction between openness and protection.
