Geodesic Dome Accessory Frame for Weatherproof Openings

Solution Overview

Problem

Existing geodesic domes face challenges in easily adding, removing, or replacing doors and windows without altering the underlying structure, leading to weatherproofing issues.

Innovation Solution

A system and method involving a base frame that mimics the triangular structure of the geodesic dome, allowing accessories like windows or doors to be attached directly to the underlying frame, with an outer frame sandwiching the membrane between the base frame to create a weather-resistant seal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If doors and windows are added to a geodesic dome, then the dome gains openings for access and light, but the weatherproofing is compromised and the structure becomes harder to seal

Engineering Contradiction:

Improveability to add openingsVSAvoidweatherproofing

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The accessory assembly is divided into separate components: a base frame that attaches to the dome structure, and an outer frame that interfaces with the membrane. This segmentation allows the opening to be added without compromising the overall weatherproofing, as each component can be separately sealed to the dome structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The base frame acts as an intermediary element between the dome's structural framework and the outer frame/membrane assembly. It provides a dedicated attachment interface that preserves the weatherproofing by creating a sealed transition zone, allowing openings to be added without directly compromising the membrane integrity.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If doors and windows are permanently installed in a geodesic dome, then the structure gains functional openings, but removing or replacing them becomes difficult and requires substantial structural alteration

Engineering Contradiction:

Improveability to add openingsVSAvoidremovability of openings

Core Design Contradiction:

Adaptability or versatilityVSEase of repair

Solution Approach 1:

The accessory assembly is divided into separate components: a base frame that attaches to the dome structure, and an outer frame that interfaces with the membrane. This segmentation allows the opening to be added without compromising the overall weatherproofing, as each component can be separately sealed to the dome structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The attachment system transitions from a permanent, fixed installation to a dynamic, removable configuration. The base frame with its attachment mechanisms (brackets, tabs, or clamps) enables the accessory assembly to be installed and removed without structural damage, providing flexibility for future modifications or replacements.

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If a simple attachment method is used for accessories, then installation becomes easier, but weatherproofing and structural integrity are compromised

Engineering Contradiction:

Improveease of installationVSAvoidweatherproofing

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The accessory assembly is divided into separate components: a base frame that attaches to the dome structure, and an outer frame that interfaces with the membrane. This segmentation allows the opening to be added without compromising the overall weatherproofing, as each component can be separately sealed to the dome structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The outer frame is designed to interface with and secure the membrane through clamping or sealing mechanisms. This allows the flexible membrane to be attached to the rigid outer frame in a weatherproof manner, maintaining the dome's weather resistance while enabling easy installation of accessories.

Inventive Principle:

Principle #30Flexible shells and thin films

AI summary

A geodesic dome accessory having an accessory frame that utilizes a base frame and an upper frame. The base frame is attached to the frame of the geodesic dome on interior to the frame. The upper frame attaches to the base frame and secures the membrane of the geodesic dome between the upper frame and the base frame, providing a weather resistant or tight seal. The base frame forms an opening to access from the exterior of the dome to the interior. The upper frame can be in a variety of configurations, including a window, door, vent passage, or stove pipe passage. The structural framing of the dome can remain with the base frame in the shape of the opening between frame elements, such as a window, or the framing can be removed with the accessory base frame forming the structural support replacing the standard framing, such as a door.
