Modular Room Cell with Underframe Anchoring for Detonation Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collapsible room cells lack sufficient protection against pressure waves from detonations, leading to structural instability and potential harm to occupants.
Innovation Solution
The design incorporates connecting means that penetrate wall panels and profile legs, an underframe surrounding the side wall panels, and enhanced profile strip connections, including cross-joint angle profiles and profiled sheets, to create a more stable structure that can withstand pressure waves and maintain stability on uneven floors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional profile strip connections are used to connect wall panels, then the structure remains simple and easy to assemble, but the structure cannot withstand pressure waves from detonations
Solution Approach 1:
The patent applies preliminary action by pre-assembling corner modules that include integrated angle profiles and connecting means before field deployment. These pre-configured modules are designed to be quickly assembled on-site, reducing the complexity of field operations while ensuring robust pressure wave resistance through the integrated corner reinforcement structure
Solution Approach 2:
The patent segments the connection structure into modular components: profile strips for panel connections, angle profiles for corner reinforcement, and separate connecting means (screws/bolts) for assembly. This segmentation allows each component to be optimized for its specific function while maintaining overall structural integrity against pressure waves
2Reliability
If wall panels are connected only by profile strips on the outside and inside, then assembly is simple, but the connection is insufficient during detonations causing wall panels to burst
Solution Approach 1:
The patent employs composite connection structures combining different material elements: metal profile strips for flexible panel connection, rigid angle profiles for corner strength, and threaded fasteners for secure assembly. This composite approach maintains ease of manufacture through standardized components while achieving reliable connections that withstand detonation forces
Solution Approach 2:
The patent adds a third dimension to the connection system by introducing angle profiles that extend perpendicular to the panel faces at corners. This dimensional addition creates three-point contact (inside profile, outside profile, angle profile) rather than two-point contact, significantly improving connection reliability under pressure wave loading while maintaining assembly simplicity through modular design
3Stability of the object's composition
If the room cell is placed directly on the ground, then setup is straightforward, but it can be lifted off during pressure waves from detonations
Solution Approach 1:
The patent applies the anti-weight principle by designing an underframe structure with feet that extend below the panel assembly to provide counterbalancing weight and mechanical anchoring. The feet create a low-center-of-gravity configuration that resists lifting forces from pressure waves, while the modular foot design maintains relative simplicity in the overall structure
Solution Approach 2:
The underframe acts as an intermediary element between the wall panel assembly and the ground. It provides a stable platform that distributes loads and prevents direct contact between the panels and ground-level hazards, while the simple foot design minimizes structural complexity

AI summary
The space cell (1) has a base wall (2) with base wall plates, side walls (4, 6, 7) with side wall plates (8), and cover walls (3) with cover wall plates. The side wall plates are connected with the cover wall plates in topside and with the base wall plates in bottom side by angular profiles that bypass the adjacent wall plates and extend horizontally. The wall plates and the angular profiles are penetrated by stud bolts that are supported at the angular profiles.
