Solution Overview

Problem

Existing thermally activated building panels face inefficiencies in thermal conduction and aesthetic issues due to the use of sound-absorbing microporous layers and perforated metal plates, which reduce thermal efficiency and make perforations visible, affecting both performance and appearance.

Innovation Solution

A thermally activated building panel with a metallized textile surface tensioned over a metal plate, where the first surface is coated with metal particles to enhance thermal conductivity and block light transmission, ensuring a smooth, even surface that hides the metal plate perforations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a sound-absorbing microporous layer is applied to the metal plate, then sound absorption is improved, but thermal conduction between the layer and metal plate is reduced

Engineering Contradiction:
Improvesound absorptionVSAvoidthermal conduction efficiency
Core Design Contradiction:
Object-affected harmful factorsVSLoss of energy

Solution Approach 1:

The textile layer acts as an intermediary between the sound-absorbing microporous layer and the metal plate. It provides both acoustic damping properties and sufficient thermal conduction, mediating between the conflicting requirements of sound absorption and thermal efficiency.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention uses a composite structure combining textile material with specific thermal and acoustic properties. This composite approach allows simultaneous achievement of sound absorption and thermal conduction that neither material could provide alone.

Inventive Principle:
Principle #40Composite materials

2Object-affected harmful factors

If a sound-absorbing microporous layer is applied to the metal plate, then sound absorption is improved, but the circular perforations become visible through the layer

Engineering Contradiction:
Improvesound absorptionVSAvoidaesthetic appearance
Core Design Contradiction:
Object-affected harmful factorsVSIllumination intensity

Solution Approach 1:

The textile layer serves as a visual intermediary that obscures the metal plate perforations from view while maintaining acoustic functionality. It mediates between the need for visible aesthetic appearance and the need for sound absorption.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Illumination intensity

If a textile is arranged on the metal plate, then aesthetic appearance is improved, but thermal conduction between the textile and metal plate is reduced

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidthermal conduction efficiency
Core Design Contradiction:
Illumination intensityVSLoss of energy

Solution Approach 1:

The invention changes the thermal parameters of the textile material by selecting specific fiber types, densities, and thicknesses that maintain adequate thermal conduction while preserving aesthetic appearance. This allows optimization of thermal parameters without sacrificing visual quality.

Inventive Principle:
Principle #35Parameter changes

4Ease of manufacture

If the textile is not tensioned, then installation is simpler, but the surface becomes uneven and perforations become visible

Engineering Contradiction:
Improveinstallation simplicityVSAvoidsurface smoothness
Core Design Contradiction:
Ease of manufactureVSShape

Solution Approach 1:

The textile is designed to be tensioned during installation to achieve the desired smooth surface, but the tensioning mechanism allows for adjustment and maintenance. This dynamic approach balances installation simplicity with aesthetic requirements.

Inventive Principle:
Principle #15Dynamics
