Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dome-shaped structures face issues with weak stability under asymmetric loads, poor seismic and wind resistance, low thermal insulation, limited use for temporary and cold buildings, complex manufacturing and installation, high material consumption, and inability to expand without compromising the structure.
Innovation Solution
A multipurpose dome-shaped building design featuring a bearing frame composed of symmetrically arranged pyramidal volumetric trusses connected by a horizontal beam, with a uniform horizontal distance between trusses, allowing for interchangeable and standard-sized facing materials that simplify manufacturing and installation, enhance strength and thermal insulation, and facilitate increased natural daylight and energy efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If dome-shaped structures use traditional cancellated frames with triangular plates and hinged connections, then the structure can be folded and erected quickly, but the stability under asymmetric loads and seismic resistance deteriorates
Solution Approach 1:
The dome structure is divided into multiple identical modular sectors (e.g., 5 sectors), each containing standardized triangular plates and hinged connections. This segmentation allows quick assembly while maintaining structural integrity through repetition of proven stable units
Solution Approach 2:
Multiple modular sectors are combined to form the complete dome structure. The sectors are connected through shared arches and quadrangles, creating a unified stable structure that benefits from the collective strength of all segments working together
2Ease of operation
If traditional dome structures use triangular plates with hinged connections, then the structure can be folded for transport, but the complexity of manufacturing and installation increases
Solution Approach 1:
The triangular plates are designed as universal standardized components that serve multiple functions: they form the structural framework, provide surface coverage, and enable folding through hinged connections. The same plate type is used throughout the entire dome, simplifying manufacturing
Solution Approach 2:
The structure incorporates hinged connections that allow the rigid triangular plates to rotate relative to each other, enabling the dome to fold into a compact configuration for transport and then unfold to its full operational shape for assembly
3Adaptability or versatility
If traditional dome structures use numerous hinged fastenings and folding frame connections, then the structure can be disassembled and reassembled, but the material consumption increases
Solution Approach 1:
The modular design with standardized triangular plates and hinged connections allows the structure to be disassembled into reusable components. The same plates and connectors can be recovered and reused in subsequent assemblies, reducing overall material consumption over the structure's lifecycle
4Stability of the object's composition
If traditional dome structures use symmetric cancellated frames, then the structure achieves geometric stability, but the scope of use for different functional purposes is limited
Solution Approach 1:
The standardized modular sectors can be configured to create domes of different sizes and shapes by varying the number of sectors. The same basic triangular plate design can serve multiple functional purposes including residential, industrial, agricultural, and temporary shelter applications
Solution Approach 2:
While maintaining symmetric geometric stability through standardized sectors, the structure allows for asymmetric functional configurations by selectively positioning door openings, window apertures, and internal layouts within the modular framework to suit different operational requirements
