Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing visual protection systems are not quick and efficient to set up and operate, especially in emergency situations like accident scenes or crime scenes, requiring manual assembly and lacking self-erection capabilities.
Innovation Solution
A mobile visual protection system made of lightweight textile material with a skeleton construction using hoses as a load-bearing framework, filled with compressed air, featuring an upper pillar and lower pillars arranged in an inverted 'V' shape, which self-erects with air pressure, and includes ballast for stability and LED lighting for enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a visual protection system uses a traditional rigid frame structure, then it provides structural stability, but it increases weight and complicates assembly procedures
Solution Approach 1:
The patent replaces rigid metal frame structures with flexible textile material that is inflated to form the protective screen. The textile material, when pressurized with air, achieves the necessary structural stability while maintaining extremely low weight. The inflated textile structure forms self-supporting pillars and screen surfaces that provide the required mechanical strength without the mass of traditional rigid frameworks.
Solution Approach 2:
The patent uses compressed air inflation to create the structural framework. Air pressure is introduced into the textile structure to form rigid-looking pillars and screen surfaces. This pneumatic approach allows the structure to achieve temporary rigidity during deployment while remaining lightweight and easily collapsible when deflated, resolving the contradiction between structural stability and weight.
2Reliability
If a visual protection system uses complex assembly procedures, then it may achieve better structural integrity, but it reduces deployment speed and requires trained personnel
Solution Approach 1:
The textile structure is pre-designed with integrated air channels and connection points that guide the inflation process. The structure is manufactured in a collapsed state ready for rapid deployment, with all structural elements pre-positioned. When air is introduced, the structure self-assembles into its functional form without requiring manual assembly steps, achieving both structural integrity and rapid deployment.
Solution Approach 2:
The inflated textile structure is self-erecting and self-supporting. Once air pressure is applied, the structure automatically forms its stable configuration without requiring external assembly assistance or trained personnel. The system serves itself by using the air pressure to both inflate and structurally stabilize the screen, eliminating complex assembly procedures while maintaining reliability.
3Manufacturing precision
If a visual protection system uses manual assembly, then it can be constructed with precise alignment, but it increases setup time and labor requirements
Solution Approach 1:
The uniform air pressure distributed throughout the textile structure ensures that all pillars and screen sections inflate to their designed dimensions and alignment simultaneously. The pneumatic system inherently provides precise alignment by equalizing pressure across the entire structure, eliminating the need for manual measurement and adjustment while maintaining manufacturing precision.
Solution Approach 2:
The structure transitions from a collapsed two-dimensional state to an inflated three-dimensional state through controlled air pressure application. This parameter change (from deflated to inflated) automatically achieves the precise spatial configuration and alignment of all structural elements, replacing time-consuming manual positioning with a rapid physical transformation.
