Solution Overview

Problem

Self-supporting modules for continuous façades suffer from vapor diffusion due to air infiltration, which compromises their performance and energy efficiency.

Innovation Solution

A self-supporting module with a polyhedral shape, featuring a load-bearing structure made of aluminum, an external finishing assembly with adjustable angles for optimal solar exposure, and an insulation packet with staggered layers of organic and synthetic materials to reduce thermal bridges and vapor diffusion, along with a ventilation gap for air circulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a continuous façade is constructed using self-supporting modules, then the building envelope is formed and structural support is provided, but vapor diffusion occurs due to air infiltration compromising thermal performance

Engineering Contradiction:
Improvestructural supportVSAvoidvapor diffusion
Core Design Contradiction:
StrengthVSLoss of energy

Solution Approach 1:

The patent implements nested insulation layers where a first insulation layer and a second insulation layer are positioned at different orientations within the module structure. The second layer is arranged perpendicular to the first layer, creating a nested configuration that blocks vapor diffusion paths while maintaining structural integrity and thermal performance.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent uses composite insulation structures combining different insulation materials with distinct thermal and vapor permeability characteristics. The first insulation layer and second insulation layer are made of different materials arranged in a composite configuration that simultaneously provides structural support and prevents vapor diffusion.

Inventive Principle:
Principle #40Composite materials

2Loss of energy

If insulation layers are added to reduce thermal bridges, then thermal insulation is improved, but the module complexity increases

Engineering Contradiction:
Improvethermal insulationVSAvoidmodule structure
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The patent divides the insulation system into segmented layers with different orientations. The first insulation layer and second insulation layer are separated and arranged perpendicular to each other, allowing each layer to be optimized for specific thermal performance requirements while simplifying the overall construction process through modular assembly.

Inventive Principle:
Principle #1Segmentation
