Retractable Fire Cover Panel Deployment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a protective cover system that can effectively deploy over buildings lowered into underground compartments to safeguard them from natural disasters such as wildfires, as existing solutions do not adequately address the requirement for a reliable and efficient method to cover the opening above the building.
Innovation Solution
An extendable cover system comprising a panel assembly, panel delivery system, and panel guide system, where panels are delivered and aligned to form a fire-proof cover across the opening, using guide rails and positioning arms to ensure proper deployment and sealing, with panels made from fire-resistant materials like fiberglass laminated composite.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective cover system is deployed over buildings lowered into underground compartments, then protection from wildfires is achieved, but the complexity of the system increases
Solution Approach 1:
The protective cover is divided into multiple deployable panels that can be sequentially positioned and sealed over the building opening. Each panel is an independent unit that can be manufactured, transported, and installed separately, reducing the complexity of deploying a single large cover while maintaining comprehensive protection.
Solution Approach 2:
Panels are pre-positioned around the building structure before the fire threat materializes. The panels are staged in a ready-to-deploy configuration, allowing for rapid coverage when needed without the complexity of assembling large components during an emergency.
2Manufacturing precision
If panels are delivered and aligned using guide rails and positioning arms, then manufacturing precision is improved, but the device complexity increases
Solution Approach 1:
Guide rails serve as intermediary structures that facilitate the precise movement and positioning of panels during deployment. The rails provide a controlled path that ensures panels are aligned correctly without requiring complex active positioning systems, simplifying the overall mechanism while maintaining precision.
Solution Approach 2:
The system replaces complex active positioning mechanisms with passive mechanical guidance structures. The guide rails and positioning arms use gravity and simple mechanical constraints to achieve precise panel alignment, eliminating the need for sophisticated motors, sensors, and control systems.
3Object-affected harmful factors
If fire-resistant materials like fiberglass laminated composite are used, then resistance to wildfires is improved, but the weight of the panels increases
Solution Approach 1:
The system uses fiberglass laminated composite materials that combine the fire resistance of fiberglass with the structural properties of laminated layers. This composite structure provides adequate fire protection while maintaining a weight that is manageable for the deployment mechanism, balancing protection requirements with operational feasibility.

AI summary
An extendable cover system and method for extending a cover over an opening is provided. The system includes a plurality of panels oriented horizontally and stacked vertically at a side of the opening, with each panel held by a corresponding panel holding arm. One or more guide rails extend across the opening to receive the panels. A panel moving mechanism moves the panels one-by-one onto the one or more guide rails. Each time a panel is deployed, the panel holding arms are lifted vertically to align a next panel with the guide rails, the next panel is then deployed, and the process continues until the opening is covered.
