Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a cable channel is integrated into the floor panel, then cable accommodation is achieved, but the thickness of the floor panel increases

Engineering Contradiction:
Improvecable accommodationVSAvoidfloor panel thickness
Core Design Contradiction:
Adaptability or versatilityVSLength of stationary object

Solution Approach 1:

The cable channel is nested within the hollow interior space of the foam core, utilizing the existing void space rather than adding external thickness. The foam core's hollow structure serves as the cable channel, allowing cables to be routed through the panel without increasing its overall thickness.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The foam core material provides a matrix structure with embedded hollow spaces that can accommodate cables. The porous/nested structure of the foam allows integration of cable pathways within the material itself rather than requiring separate cable management components.

Inventive Principle:
Principle #31Porous materials

2Adaptability or versatility

If a cable channel is integrated into the floor panel, then cable routing is enabled, but mechanical stability deteriorates

Engineering Contradiction:
Improvecable routingVSAvoidmechanical stability
Core Design Contradiction:
Adaptability or versatilityVSStrength

Solution Approach 1:

The floor panel uses a composite structure combining foam core material with hollow spaces for cable routing. The foam provides structural integrity while the hollow interior accommodates cables, achieving both mechanical stability and cable routing functionality through material composition rather than adding separate components.

Inventive Principle:
Principle #40Composite materials

3Adaptability or versatility

If existing floor panels are modified to accommodate cable channels, then cable installation is possible, but installation complexity increases

Engineering Contradiction:
Improvecable installationVSAvoidinstallation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cable channel is pre-integrated into the foam core during manufacturing, so that cable routing pathways are already established before installation. This preliminary integration eliminates the need for complex on-site modifications or additional cable management components during installation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The cable channel functionality is merged with the structural floor panel itself rather than being a separate component. The hollow foam core serves dual purposes as both structural support and cable conduit, simplifying the overall system and installation process.

Inventive Principle:
Principle #5Merging (Combining)

4Adaptability or versatility

If cable channels are added to floor panels, then electrical systems can be integrated, but weight increases

Engineering Contradiction:
Improveelectrical system integrationVSAvoidfloor panel weight
Core Design Contradiction:
Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The foam core material provides a lightweight matrix structure with embedded hollow spaces for cable routing. The foam's inherent porosity and low density allow integration of cable pathways without significantly increasing weight, as the hollow spaces utilize the existing material structure rather than adding dense solid components.

Inventive Principle:
Principle #31Porous materials

AI summary

A floor panel 100, 106 for a floor of a passenger cabin 400 of a mobile platform 200 is provided, which comprises a base body 100 with an integrated cable channel 106 and a cover element 303, 304 covering the cable channel. The base body is realized in the form of a sandwich component including two honeycomb structures 103, 104, between which the cable channel is arranged. The cover element is firmly attached to the base body, thereby creating a self-supporting floor panel. Since the cover element is firmly attached to the base body, the thickness and weight of the base body may be reduced.
