Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing shelters constructed from Autoclaved Aerated Concrete (AAC) and Structural Insulated Panels (SIPs) face difficulties in attaching panels, resulting in joints that are not strong enough to withstand severe weather conditions such as high winds and extreme weather events like hurricanes and typhoons.

Innovation Solution

The use of modular brackets with flanges and clamping elements that securely join AAC or SIP panels together, including corner bracket assemblies with tubular retainers and threaded rods to anchor the structure to a foundation, enhancing the structural integrity and stability of the shelter.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If conventional attachment methods are used for AAC and SIP panels, then the structure can be assembled, but the joints are not strong enough to withstand severe weather conditions such as high winds and hurricanes

Engineering Contradiction:

Improvejoint strengthVSAvoidweather resistance

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

The bracket is divided into multiple functional segments: flanges for panel attachment, clamping elements for securing, and integration with corner bracket assemblies. This segmentation allows each component to be optimized for its specific function, resulting in a joint system that can withstand severe weather conditions while maintaining ease of assembly.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The joint system combines multiple materials and components: brackets (metal), clamping elements (metal or composite), fasteners, and panel materials (AAC or SIP). This composite approach creates a unified joint assembly that leverages the strengths of each material to achieve superior weather resistance and joint strength.

Inventive Principle:

Principle #40Composite materials

2Reliability

If modular brackets with clamping elements are used to strengthen joints, then weather resistance improves, but the complexity of the attachment system increases

Engineering Contradiction:

Improveweather resistanceVSAvoidattachment system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The bracket design incorporates multiple functions into a single component: flanges for panel attachment, clamping elements for securing panels together, and integration points for corner bracket assemblies. This multi-functionality reduces the number of separate components needed, simplifying the overall attachment system while maintaining superior weather resistance.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The bracket design merges the functions of multiple traditional attachment components into a single integrated unit. By combining flanges, clamping elements, and fastening mechanisms into one bracket assembly, the system reduces complexity while achieving the required weather resistance through unified structural action.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A structure is constructed from a plurality of panels formed of Autoclaved Aerated Concrete (AAC), Structural Insulated Panels, plywood or the like. The shelter also includes bracket members that connect at least two panels together and clamp at least one panel to the bracket with clamping structures that activate when fasteners are secured to the bracket.
