Solution Overview
Problem
Conventional dome structures face inefficiencies in assembly and lack of effective temperature insulation, with existing methods requiring complex connections and multiple layers, leading to increased construction time and cost, and inadequate resistance to environmental factors like fire, corrosion, and earthquakes.
Innovation Solution
The development of a pre-fabricated dome structure using modular assemblies with transparent panels (glass or synthetic resin) assembled in hexagonal and pentagonal configurations, allowing for two-layer strut interconnections to form a semi-spherical or spherical shape, providing enhanced insulation and resistance through vacuum-sealed panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional dome structures use complex connection methods with multiple layers and components, then structural strength is improved, but assembly time and construction cost increase
Solution Approach 1:
The dome structure is divided into modular units (triangular panels with integrated nodes) that can be pre-assembled and then connected together. This segmentation allows for simplified on-site assembly while maintaining structural integrity through the modular design.
Solution Approach 2:
The complex connection components and structural elements are pre-assembled into complete modular units before delivery to the construction site. This preliminary assembly reduces on-site construction time and complexity while ensuring proper structural connections are already in place.
2Ease of manufacture
If conventional dome structures use single-layer transparent panels, then construction simplicity is maintained, but thermal insulation performance is insufficient
Solution Approach 1:
The transparent panels are constructed as composite structures with multiple layers including transparent insulation materials, vacuum spaces, and thermal break elements. This composite design provides enhanced thermal insulation performance while maintaining the transparency and aesthetic appearance of the dome structure.
Solution Approach 2:
Vacuum spaces are incorporated between transparent panel layers to create an inert environment that eliminates heat conduction and convection, significantly improving thermal insulation performance while maintaining a relatively simple structural configuration.
3Stability of the object's composition
If conventional dome structures use traditional assembly methods, then structural integrity is achieved, but fire-resistance and corrosion-resistance are inadequate
Solution Approach 1:
The structural components use composite materials that combine metals with protective coatings or composite structures that integrate fire-resistant and corrosion-resistant properties. These composite materials maintain structural integrity while providing enhanced resistance to fire and corrosion.
Solution Approach 2:
Protective coatings and resistant layers are applied to structural components during manufacturing before delivery to the site. This beforehand protection ensures fire-resistance and corrosion-resistance are built into the structure, enhancing reliability without compromising structural integrity.

AI summary
A pre-fabricated dome and a spherical structure include strut assembly sets, into which glass panels or synthetic resin transparent plates are to be inserted, are assembled into 5 sets of hexagonal modular assemblies around a pentagonal assembly to build a primary pentagonal modular assembly, and further 5 sets of primary pentagonal modular assemblies, into which upper and lower, (outer and inner) struts are assembled in 2 layers (of outer and inner walls), are interconnected to build a semi-spherical dome, and if 12 sets of primary pentagonal modular assemblies are assembled, a solid cylindrical structure can be built to provide a perfect block between the outdoor and the indoor so that the room temperature will not be affected at all by the outdoor temperature.
