Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional geodesic dome structures require a large number of connectors and triangular panels, leading to complex and costly construction, limited interior space, and potential water intrusion issues, which hinder efficient and cost-effective use for residential or off-grid living applications.
Innovation Solution
A hybrid geodesic structure featuring a geodesic shell surrounding a central core structure with fewer connectors and triangular panels, incorporating a cupola for ventilation and natural light, and utilizing prefabricated SIP panels for insulation and standard window/door sizes, along with a kit for easy assembly, to provide a self-contained, energy-efficient, and cost-effective living solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional geodesic dome structures use a large number of connectors and triangular panels, then structural strength and stability are improved, but construction complexity and cost increase
Solution Approach 1:
The dome is divided into modular components including prefabricated SIP panels and standardized connectors that can be assembled in sections. This segmentation allows for easier construction while maintaining structural integrity through the modular design of the geodesic framework.
Solution Approach 2:
The patent employs composite construction by combining SIP (structural insulated panel) materials with the geodesic framework. These composite panels integrate insulation, framing, and sheathing in a single unit, reducing the number of separate components needed while maintaining or improving structural strength.
2Stability of the object's composition
If conventional geodesic dome structures use a large number of triangular panels, then structural stability is improved, but interior space is reduced
Solution Approach 1:
The dome structure transitions from uniform triangular panels to a hybrid design where SIP panels are strategically placed in specific zones. This local quality approach allows for optimized structural stability in load-bearing areas while maximizing interior space in habitable zones through the use of vertical walls and flat ceilings.
3Strength
If conventional geodesic dome structures use many connectors, then structural integrity is improved, but waterproofing reliability deteriorates
Solution Approach 1:
The patent extracts and eliminates the need for numerous connectors by using SIP panels that integrate structural and waterproofing functions. The SIP panels serve as both structural elements and weather barriers, removing the waterproofing layer that would otherwise be compromised by multiple connector joints.
4Ease of manufacture
If conventional geodesic dome structures use standard window and door sizes, then ease of manufacture is improved, but adaptability to dome geometry deteriorates
Solution Approach 1:
The patent introduces vertical walls and flat ceiling surfaces within the dome structure, adding a vertical dimension to the traditional geodesic dome geometry. This dimensional change allows for standard window and door sizes to be used in vertical orientations while maintaining adaptability to the overall dome shape through the geodesic framework.

AI summary
A hybrid geodesic structure includes a core structure and a geodesic shell surrounding the core structure. The core structure extends from a base at a center of the geodesic shell through an upper extent of the geodesic shell opposite to the base. The core structure supports the geodesic shell at an upper extent and includes a roof.
