Solution Overview

Problem

Current methods for installing equipment and fittings in means of transport, such as aircraft, require significant modification effort and lead time due to individual adaptations, leading to heat losses, incorrect cutouts, and vulnerability of air-conditioning ducts, with wiring cables having freely suspended sections and potential damage.

Innovation Solution

A detachable panel with a plate-like insulating body featuring integrated air-conditioning ducts and cable conduits, eliminating the need for separate holders and cutouts, and allowing predefined routing of wiring cables, which reduces installation complexity and enhances insulation and structural support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If holders are initially fastened on the primary structure and insulating mats are fastened with cutouts for holders, then wiring cables can be installed, but substantial modification effort is required and construction leadtime increases

Engineering Contradiction:
Improveinstallation processVSAvoidconstruction leadtime
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent combines the insulating mat and cable conduit into a single integrated panel assembly. The cable conduits are directly formed in the insulating mat, eliminating the need for separate holders and multiple installation steps. This merging of components reduces modification effort and shortens construction leadtime.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cable conduits are pre-formed in the insulating mat during manufacturing, before installation. This preliminary action eliminates the need for on-site modification and holder installation, allowing wiring cables to be directly routed through the pre-formed conduits during a quicker installation process.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If holders are spaced apart for wiring cables, then cable routing is possible, but wiring cables have freely suspended sections that are vulnerable to damage

Engineering Contradiction:
Improvecable routingVSAvoidcable protection
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The cable routing function is merged into the insulating mat itself through integrally formed cable conduits. This eliminates the need for separate holders and provides continuous protection for wiring cables along their entire routing path, preventing freely suspended sections and reducing damage risk.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If cutouts are produced in insulating mats for holders, then cable installation is enabled, but heat losses occur and insulating effect deteriorates

Engineering Contradiction:
Improvecable installationVSAvoidheat loss
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

The cable routing function is integrated into the insulating mat through formed conduits rather than requiring cutouts. This maintains the continuous insulating material around cable pathways, eliminating heat loss gaps while still enabling cable installation through the pre-formed conduits.

Inventive Principle:
Principle #5Merging (Combining)

4Ease of operation

If air-conditioning ducts are fastened separately to the primary structure, then air-conditioning installation is possible, but ducts are vulnerable to strain whitening under compressive loads

Engineering Contradiction:
Improveair-conditioning installationVSAvoidduct durability
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The air-conditioning ducts are integrated with the insulating panel as a unified assembly. The insulating panel provides structural support and protection for the ducts, distributing and reducing compressive loads. This merging prevents strain whitening while maintaining installation flexibility.

Inventive Principle:
Principle #5Merging (Combining)

5Ease of repair

If interior lining is damaged, then replacement is needed, but entire side panel must be exchanged in prior art

Engineering Contradiction:
Improveinterior lining replacementVSAvoidpanel assembly
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The design separates the interior lining from the insulating panel with integrated cable conduits and air-conditioning ducts. This segmentation allows the interior lining to be replaced independently without affecting the structural insulating panel, unlike prior art where the entire side panel must be exchanged.

Inventive Principle:
Principle #1Segmentation
