Solution Overview

Problem

Existing systems for fixing equipment to aircraft floors are rigid, bulky, and limit modularity, requiring predetermined rail positions and adapting panel dimensions, which complicates installation and layout, and do not allow for easy removal or reuse.

Innovation Solution

A device with a clamping member and anchoring pin that can be translated and rotated to securely attach equipment to a panel without the need for rails, allowing for easy installation, removal, and reuse, and accommodating panels of any shape or size, while being lightweight and adaptable.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If rigid mounting rails are used to fix equipment to the floor panel, then the mechanical strength and stability of the attachment are improved, but the device complexity and weight increase, and modularity is reduced

Engineering Contradiction:
Improvemechanical strengthVSAvoiddevice complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The mounting system is divided into separate functional components: a mounting plate that attaches to the floor panel, and a separate equipment interface. This segmentation allows the system to achieve the required mechanical strength through the mounting plate while keeping the overall device complexity low by using simple, modular components rather than a complex rigid rail structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent extracts the essential function of equipment attachment from the complex rail system. By using a simple mounting plate with attachment means that directly secures equipment to the floor panel, the solution removes the unnecessary intermediate rail structure, thereby reducing device complexity while maintaining the required mechanical strength for secure attachment.

Inventive Principle:
Principle #2Taking out (Extraction)

2Stability of the object's composition

If predetermined rail positions are used to accommodate floor panels, then the stability of the mounting system is improved, but the adaptability to different panel shapes and sizes is reduced

Engineering Contradiction:
ImprovestabilityVSAvoidadaptability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The mounting plate is designed with universal attachment means that can accommodate different floor panel shapes and sizes. The attachment mechanism is not restricted to predetermined positions but can be adapted to various panel configurations, providing both stability through secure attachment and versatility in accommodating different panel types.

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

Solution Approach 2:

The mounting system incorporates adjustable and adaptable features that allow it to conform to different panel geometries. Rather than requiring fixed predetermined positions, the attachment means can be positioned and configured to match the specific panel being used, maintaining stability while providing adaptability to various panel shapes and sizes.

Inventive Principle:
Principle #15Dynamics

3Strength

If floor panels are inserted into gaps between rails, then the mechanical strength of the floor structure is improved, but the ease of installation and layout flexibility are reduced

Engineering Contradiction:
Improvemechanical strengthVSAvoidease of installation
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The patent removes the complex rail structure and the requirement to insert panels into gaps between rails. Instead, a simplified mounting plate system is used that directly attaches equipment to the panel, eliminating the intermediate rail structure and making installation straightforward without compromising mechanical strength.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Rather than having panels fit into gaps between rails (panel-to-rail interface), the invention inverts the approach by having mounting plates attach directly to panels (mounting-plate-to-panel interface). This reversal simplifies the installation process and maintains structural integrity by creating a direct attachment path from equipment to floor panel.

Inventive Principle:
Principle #13The other way round (Inversion)

4Adaptability or versatility

If removable and reusable attachment devices are used instead of rigid rails, then the modularity and ease of removal are improved, but the mechanical strength may be compromised

Engineering Contradiction:
ImprovemodularityVSAvoidmechanical strength
Core Design Contradiction:
Adaptability or versatilityVSStrength

Solution Approach 1:

The attachment system is segmented into a removable mounting plate with distinct attachment means, allowing the equipment to be securely mounted while enabling easy removal and reuse. The segmentation provides both the modularity needed for reconfigurability and the focused mechanical strength at the attachment points through the dedicated mounting plate design.

Inventive Principle:
Principle #1Segmentation
