Solution Overview

Problem

Existing building roofing materials, particularly metal sheets, lack thermal and acoustic insulation, and the installation of conventional insulation materials is discouraged due to the risk of damage and deterioration, making it impractical for regions prone to cyclones or hurricanes.

Innovation Solution

A composite building cladding material comprising a sheet metal layer bonded with a thermally insulating component, such as bubble-filled synthetic film or closed-cell foam, and optionally a reflective aluminum layer, which is easily applied directly to the roof, providing integrated thermal and acoustic insulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a simple metal sheet roof is used, then the roof provides durability against cyclones and hurricanes, but it generates significant noise during heavy rain or hailstorms and provides no thermal insulation

Engineering Contradiction:

Improvedurability against cyclonesVSAvoidnoise generation and thermal insulation deficiency

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent combines the metal sheet roof with thermal insulation material and sound insulation material into a single integrated roofing structure. The metal sheet is directly bonded to the insulation materials, merging the protective function of the metal with the insulating and sound-absorbing functions of the other materials, thereby eliminating noise and thermal issues while maintaining cyclone resistance.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The invention creates a composite roofing structure consisting of multiple materials with different properties: metal sheet for structural strength and cyclone resistance, thermal insulation material for heat control, and sound insulation material for noise reduction. This composite approach allows simultaneous achievement of durability, thermal insulation, and acoustic comfort.

Inventive Principle:

Principle #40Composite materials

2Temperature

If conventional thermal insulation is installed under metal sheet roofing, then thermal insulation is provided, but the risk of damage to the roof and deterioration of insulation discourages users from undertaking such work

Engineering Contradiction:

Improvethermal insulationVSAvoidrisk of insulation deterioration

Core Design Contradiction:

TemperatureVSReliability

Solution Approach 1:

The thermal insulation material is merged with the sound insulation material and metal sheet into a single pre-assembled unit. This integration ensures that the insulation material is permanently protected by the durable metal sheet, eliminating the risk of deterioration that occurs with separately installed insulation.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The design provides beforehand protection for the insulation material by enclosing it within the composite structure. The metal sheet and sound insulation material act as protective layers that shield the thermal insulation from damage and deterioration before any potential harm can occur.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

3Temperature

If conventional insulation materials are installed separately under metal roofs, then thermal insulation is achieved, but additional installation work and complexity are required

Engineering Contradiction:

Improvethermal insulationVSAvoidinstallation complexity

Core Design Contradiction:

TemperatureVSDevice complexity

Solution Approach 1:

Multiple functions (thermal insulation, sound insulation, structural protection) are merged into a single pre-assembled composite unit. This eliminates the need for separate installation of multiple layers and reduces installation complexity while achieving all desired performance characteristics.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The insulation materials and metal sheet are pre-assembled into a complete roofing unit before installation. This preliminary action of combining all components into one unit simplifies the final installation process and eliminates the need for complex on-site assembly of multiple separate materials.
