Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing civil defence shelters are complex and labor-intensive to assemble, with reduced structural reliability due to numerous connecting elements, limiting their practicality and efficiency.
Innovation Solution
A modular protective shelter design featuring a hemispherical roof, reinforced concrete walls, and labyrinthine partitions, with reinforced buttresses and quick-connect elements, forming a compact and reliable structure that enhances protection against blast effects and shock waves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If numerous wall, floor, and ceiling panels are used to construct the shelter, then the shelter can be assembled from modular components, but the assembly becomes complex and labor-intensive
Solution Approach 1:
The patent merges multiple separate panels (wall, floor, ceiling) into integrated monolithic elements. Each structural element combines multiple functions in a single component, eliminating the need for numerous separate panels and their connecting elements, thus reducing assembly complexity while maintaining modular deployability
2Adaptability or versatility
If numerous connecting elements are used to join panels, then the modular structure can be assembled, but structural reliability is reduced
Solution Approach 1:
The patent extracts and eliminates the connecting elements from the modular structure. Instead of joining multiple panels through numerous connectors, the design uses monolithic elements that require no connecting components, thereby removing the reliability weaknesses associated with multiple connection points while preserving modular assembly capability
3Ease of manufacture
If traditional rectangular shelter designs are used, then construction is straightforward, but protective performance against blast effects and shock waves is reduced
Solution Approach 1:
The patent applies curved surfaces and spherical geometry to the shelter structure. The hemispherical roof and rounded corners distribute blast loads and shock waves more effectively than flat rectangular surfaces, enhancing protective performance while maintaining construction feasibility through standardized curved elements
4Loss of time
If the shelter is designed to be compact and quick to assemble, then deployment time is reduced, but structural strength and reliability may be compromised
Solution Approach 1:
The patent employs pre-assembled monolithic elements that are prepared in advance with integrated reinforcement and connection features. These pre-fabricated components arrive ready-to-install, eliminating on-site construction complexity and enabling rapid assembly without compromising structural integrity, as the strength is built into the elements during manufacturing

AI summary
A civil defence protective structure comprising a building (body) (1), walls (4) and a roof (2). The roof (2) has a hemispherical cross-section, the edges of which have a flat section (3) designed to join with the flat edges of the rectangular walls (4). The structure has partitions (10), in the upper part of which there are through holes (11) with a crossbar (12) in the lower part, which divide the partition (10) into an inner part (13) and an outer part (14) relative to the entire structure. All structural elements are made of prefabricated reinforced concrete elements and are connected to each other to form a single room with an entrance.
