Aircraft Cabin Temporary Floor Slabs with Interlocking Projections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of conventional temporary floors in aircraft cabins is complicated due to varying rail spacings between seat and hostess rails, leading to time-consuming setup and increased risks of accidents and object falls, as well as non-uniform working surfaces and interstice imbalances.
Innovation Solution
A modular temporary floor system comprising slabs with complementary projections and housings for precise assembly, along with gripping tools and non-slip coatings to facilitate quick installation and reduce accident risks, featuring undercut edges for easy assembly and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional boards are used to construct the temporary floor, then the floor can be installed on the rails, but the installation becomes time-consuming and complicated due to varying rail spacings
Solution Approach 1:
The patent applies universality by designing a single standardized slab that can accommodate multiple rail spacing configurations. The slab incorporates adjustable support elements and complementary projection-housing connections that allow it to adapt to different distances between seat rails and hostess rails, eliminating the need for multiple specialized board types while reducing installation time
2Ease of operation
If conventional boards are used without interlocking mechanisms, then the floor can be quickly installed, but the junctions create interstices that unbalance operators and increase the risk of objects falling
Solution Approach 1:
The patent applies the nesting principle through complementary projections on one slab that fit into housings on adjacent slabs. This interlocking mechanism eliminates gaps and interstices between slabs, creating a continuous, stable surface that prevents objects from falling through while maintaining ease of installation through the simple plug-and-socket connection
3Adaptability or versatility
If multiple models of boards are provided to adapt to different spaces, then the floor can fit all rail configurations, but the installation becomes complicated and time-consuming
Solution Approach 1:
The patent eliminates device complexity by replacing multiple specialized board models with a single universal slab design. The slab achieves adaptability to different rail spacings through integrated adjustable support elements and modular connection systems, reducing inventory requirements and simplifying installation procedures
4Adaptability or versatility
If the seat rails have different heights, then the floor can accommodate various rail configurations, but the upper working surface becomes non-uniform
Solution Approach 1:
The patent applies local quality by incorporating adjustable support elements at specific locations on each slab that can be independently positioned to compensate for varying rail heights. This allows the slab to adapt locally to different rail configurations while maintaining a uniformly flat upper working surface across the entire floor

AI summary
The invention relates to a temporary floor (25), placed on rails (1, 2) and stiffeners that form the structure of a permanent aircraft cabin floor, forming a continuous surface and composed of slabs (15) assembled by raised sections. It completely covers the rails. This temporary floor comprises a plurality of identical slabs with complementary raised sections to facilitate assembly and disassembly of the floor.
