Deployable Indoor Shelter Hinged Sections Gap Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Classrooms in schools and academic institutions are not adequately protected from hazards like shooters or earthquakes, as existing safety measures, such as face recognition and bulletproof furniture, only provide limited protection for individuals and do not ensure the safety of all people inside.
Innovation Solution
A deployable indoor shelter system that can be quickly deployed within a classroom, comprising multiple sections connected by hinges and made of bulletproof materials, which forms a safe zone by expanding between walls and can be easily withdrawn to occupy minimal space when not in use, with features like metal sheets to cover gaps and wheels for mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bulletproof furniture is used to protect individuals, then protection for single person is improved, but protection for all people in classroom is insufficient
Solution Approach 1:
The shelter is divided into multiple sections that can be independently positioned and configured. Each section can be adjusted to accommodate different numbers and positions of occupants, allowing the system to adapt to various threat scenarios and occupancy levels while maintaining comprehensive protection for all people in the classroom.
Solution Approach 2:
The shelter structure is designed to be dynamic and reconfigurable rather than fixed. Sections can be moved, adjusted, and repositioned based on the location and nature of the threat, enabling the protection system to adapt to different attack vectors and occupancy patterns while ensuring reliable protection for all occupants.
2Reliability
If a fixed shelter structure is installed in classroom, then protection coverage is improved, but space disturbance is increased
Solution Approach 1:
The shelter transitions from a static fixed structure to a dynamic deployable system. When not needed, the shelter sections can be collapsed or retracted to occupy minimal space, allowing normal classroom activities to continue uninterrupted. When deployed, the same sections rapidly form a comprehensive protective enclosure, providing reliable protection coverage only when required.
Solution Approach 2:
The shelter sections are designed to nest within each other or collapse into a compact configuration when not in use. The modular sections can be stored in a compact state that occupies minimal classroom space, similar to nested dolls, while still being capable of expanding into a full protective enclosure when deployed to protect occupants.
3Area of stationary object
If deployable shelter sections are used, then space disturbance is reduced, but gap spaces between sections may be formed
Solution Approach 1:
Metal sheets are introduced as intermediary elements between the deployable shelter sections. These sheets fill the gap spaces that naturally form between modular sections, creating a continuous and intact shelter envelope. The metal sheets act as mediators that maintain shelter integrity while allowing the modular sections to be deployed and collapsed without compromising the protective barrier.
4Area of stationary object
If shelter wall expands between parallel walls, then safe zone area is increased, but deployment complexity is increased
Solution Approach 1:
The shelter wall is segmented into multiple independent sections that can be deployed and positioned separately. Each section can be independently manipulated during deployment, allowing the overall structure to expand between parallel walls through coordinated movement of individual segments rather than moving a single complex entire structure.
Solution Approach 2:
The deployment mechanism utilizes dynamic, movable connections between shelter sections that allow the wall to expand and contract smoothly between parallel walls. The modular design with movable joints enables the shelter to adapt its shape and size in real-time during deployment, reducing the complexity of the overall deployment mechanism while still achieving the desired safe zone area.

AI summary
A deployable indoor shelter is disclosed that comprises a deployable shelter that forms a safe zone. When the shelter is withdrawn, it occupies substantially undisturbed indoor space and when the deployable shelter is deployed, the safe zone is confined within at least one wall of the indoor space and the deployable shelter.
