Interlocking Floor Panels for Passenger Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional aircraft flooring is cumbersome to install and difficult to repair due to firm bonding between panels, and traditional hardwood flooring is impractical for aircraft due to weight, noise absorption, and slip hazards, as well as incompatibility with vertical loads and movement.
Innovation Solution
A flooring system featuring interlocking floor panels with a top sheet, a bottom sheet, and a cellular body that allows lateral motion while restricting vertical motion, enabling easy installation and replacement, and using composite materials for weight reduction and aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional aircraft flooring uses firm bonding between panels, then structural strength is improved, but ease of repair deteriorates
Solution Approach 1:
The flooring system is divided into modular panels that can be independently removed and replaced. Each panel is a self-contained unit with interlocking features, allowing individual panel replacement without disturbing adjacent panels, thus enabling easy repair while maintaining overall structural integrity through the modular design.
Solution Approach 2:
The flooring system transitions from a static, permanently bonded structure to a dynamic, reconfigurable system. Panels can be easily installed and removed through interlocking mechanisms, allowing the flooring to adapt to maintenance needs while maintaining structural strength during normal operation.
2Ease of manufacture
If traditional hardwood flooring is used, then aesthetic appeal is improved, but weight increases
Solution Approach 1:
The flooring panels utilize composite materials that replicate the aesthetic appearance of traditional hardwood flooring while significantly reducing weight. The cellular structure with top and bottom sheets creates a lightweight composite that maintains visual appeal without the excessive weight of solid hardwood, addressing both aesthetic requirements and weight constraints.
3Stability of the object's composition
If conventional flooring installation methods are used, then structural stability is improved, but installation time increases
Solution Approach 1:
The panels are pre-manufactured with interlocking features already integrated into their structure. This preliminary preparation of connection mechanisms allows for rapid installation without requiring complex on-site bonding operations, significantly reducing installation time while ensuring structural stability through the pre-engineered interlocking system.
Solution Approach 2:
The system replaces traditional mechanical bonding methods (adhesives, screws) with an interlocking mechanical feature system. This substitution enables faster installation through simple snap-fit or click-lock mechanisms while maintaining structural stability through precise geometric interlocking, eliminating time-consuming bonding processes.
4Force
If floor panels are firmly bonded together, then load bearing capacity is improved, but ease of replacement deteriorates
Solution Approach 1:
The flooring system is segmented into discrete panels that bear load independently through their interlocking connections to the substrate and adjacent panels. This segmentation allows individual panels to be replaced without affecting the load-bearing capacity of the overall system, as the interlocking features maintain structural integrity during and after replacement.

AI summary
An example floor panel for a flooring system in a passenger vehicle includes a top sheet, a bottom sheet, a body situated between the top sheet and the bottom sheet, and an interlocking feature that extends outward from the body for slidably engaging an adjacent floor panel. An example flooring system in a passenger vehicle includes a first set of floor panels including panels rigidly attached to a structure of the passenger vehicle, and a second set of floor panels and each floor panel of the second set of floor panels has an interlocking feature for slidably engaging an adjacent floor panel and for enabling lateral relative motion to occur and restricting vertical relative motion between panels of the second set of floor panels and a respective adjacent floor panel.
