Solution Overview

Problem

Aircraft interior components require numerous additional parts for functional integration, leading to increased weight and material usage, which contradicts the goal of reducing weight in aircraft construction.

Innovation Solution

A structural element with a load topology optimized bioinspired generative design that integrates functional components directly into the structural element, eliminating the need for additional mounting components by utilizing accommodating spaces within the structure for wiring, plumbing, and other functionalities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If functional components are mounted to honeycomb panels using bracket elements and screws, then functional integration is achieved, but the number of parts increases and weight increases

Engineering Contradiction:
Improvefunctional integrationVSAvoidweight
Core Design Contradiction:
Adaptability or versatilityVSWeight of stationary object

Solution Approach 1:

The patent merges the structural panel and functional component mounting into a single integrated structure. The bracket elements are eliminated by directly forming functional component recesses in the honeycomb panel, allowing functional components to be mounted without additional bracket parts, thus reducing total part count and weight while maintaining functional integration capability

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The honeycomb panel is designed to serve multiple functions: it provides structural support and simultaneously integrates mounting functionality through formed recesses. This multi-functional design eliminates the need for separate bracket elements, reducing the number of parts and overall weight while achieving functional integration

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

2Adaptability or versatility

If functional components are mounted to honeycomb panels using bracket elements and screws, then functional integration is achieved, but the number of parts increases

Engineering Contradiction:
Improvefunctional integrationVSAvoidnumber of parts
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the structural panel and mounting functionality into a single integrated component. By forming recesses directly in the honeycomb panel, the design eliminates separate bracket elements and reduces the number of parts, simplifying the overall device complexity while maintaining functional integration

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent extracts the mounting function from separate bracket elements and integrates it directly into the honeycomb panel structure. This extraction of the mounting function from standalone components and its integration into the panel itself reduces the number of parts and simplifies the overall device complexity

Inventive Principle:
Principle #2Taking out (Extraction)
