Solution Overview

Problem

Existing gas-filled building panels experience significant buckling due to thermal expansion and contraction, leading to air pressure equalization issues and mechanical/esthetic problems, particularly in translucent or transparent panels where traditional solutions fail to maintain panel flatness and gas retention.

Innovation Solution

A multi-chamber gas-filled building panel design featuring parallel glass plates with insulation gas chambers separated by thin, transparent polymer foils and an air-filled chamber connected to the surrounding air through openings for pressure equalization, using gas-impermeable dividers and spacers to manage expansion and contraction while maintaining panel flatness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If gas-filled panels are used for thermal insulation, then thermal insulation performance is improved, but buckling occurs during thermal expansion and contraction

Engineering Contradiction:
Improvethermal insulation performanceVSAvoidpanel flatness
Core Design Contradiction:
Loss of energyVSShape

Solution Approach 1:

The patent divides the gas-filled panel into multiple chambers separated by dividers. This segmentation allows each chamber to expand and contract independently, distributing the thermal stress and preventing buckling of the entire panel while maintaining insulation performance.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces air-filled chambers as intermediary elements between the gas-filled insulation chambers and the external environment. These air chambers act as buffer zones that absorb volumetric changes during thermal expansion and contraction, protecting the insulation gas chambers from pressure-induced buckling.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of energy

If gas-filled panels are used for thermal insulation, then energy efficiency is improved, but gas sealing becomes problematic during dynamics

Engineering Contradiction:
Improveenergy efficiencyVSAvoidgas sealing
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

By segmenting the insulation system into multiple sealed gas chambers separated by dividers, the patent ensures that each chamber maintains its own gas seal independently. This segmentation prevents gas leakage from propagating across the entire panel while allowing controlled pressure equalization through the air chambers.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The air-filled chambers serve as intermediary pressure equalization zones that allow controlled gas exchange without compromising the sealed insulation gas chambers. This intermediary system maintains gas sealing reliability by providing a buffer that absorbs pressure changes without directly exposing the insulation gas to external pressure variations.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of manufacture

If traditional panel designs are used, then manufacturing is simpler, but air pressure equalization during thermal dynamics is not achieved

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidair pressure equalization
Core Design Contradiction:
Ease of manufactureVSStress or pressure

Solution Approach 1:

The patent segments the panel into distinct functional zones (gas-filled chambers, air-filled chambers, and divider regions) that can be manufactured and assembled using standard insulation glass technology. This segmentation allows for straightforward fabrication of each component while achieving complex pressure equalization functionality through their combination.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The dividers and spacers in the patent serve multiple functions: they separate gas chambers, provide structural support, enable pressure equalization, and maintain panel geometry. This multi-functionality achieves air pressure equalization during thermal dynamics without requiring separate dedicated components, thereby maintaining manufacturing simplicity.

Inventive Principle:
Principle #6Universality (Multi-functionality)
