Aircraft Cabin Monument Segmented Sidewall Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cabin monuments for aircraft require complex installation processes due to multiple components and lack efficient fixing mechanisms, leading to increased installation time and mechanical load on the structure.
Innovation Solution
A cabin monument design featuring a floor panel and a surrounding sidewall assembled from two mechanically coupled wall parts with overlapping fixing sections, allowing for simplified assembly and reduced component count, along with a clamping mechanism for secure attachment to the floor panel, which absorbs mechanical loads during installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple components are used to form the cabin monument, then the structural strength and stability are improved, but the installation time and complexity increase
Solution Approach 1:
The sidewall is divided into a first wall part and a second wall part that can be assembled together. This segmentation allows the components to be transported through access openings and assembled inside the aircraft body, maintaining structural integrity while facilitating easier installation compared to a single large component.
Solution Approach 2:
The fixing section is integrated directly into the wall parts, combining the mounting function with the structural component. This eliminates the need for separate fixing mechanisms and reduces the number of installation steps, thereby reducing installation time while maintaining secure attachment.
2Stability of the object's composition
If multiple components are used to form the cabin monument, then the structural stability is improved, but the number of components and handling complexity increase
Solution Approach 1:
The sidewall is segmented into two wall parts that are assembled together using connecting sections. This provides structural stability while keeping the segmentation minimal to avoid excessive complexity. The floor panel is also segmented into a front section and rear section for similar reasons.
Solution Approach 2:
The connecting sections serve multiple functions: they join the wall parts together, provide structural reinforcement, and enable adjustable positioning. This multi-functionality reduces the need for additional specialized components, thereby reducing overall complexity while maintaining stability.
3Length of moving object
If the sidewall is assembled from multiple wall parts, then the transportability through access openings is improved, but the assembly complexity increases
Solution Approach 1:
The sidewall is divided into smaller wall parts that can fit through the aircraft's access openings. The connecting sections are designed to join these parts together inside the cabin, creating the complete sidewall structure. This segmentation enables transport through limited openings while maintaining the ability to form a complete structural element.
Solution Approach 2:
The wall parts and connecting sections are designed and pre-configured to assemble together in a predetermined manner. The connecting sections have predetermined engagement features that guide the assembly process, reducing the complexity of on-site assembly despite the segmented design.
4Reliability
If a fixing mechanism is provided on the wall parts, then the secure attachment to the floor panel is improved, but the mechanical load on the sidewall increases
Solution Approach 1:
The fixing section is positioned to extend in a direction transverse to the main longitudinal axis of the cabin monument. This transverse orientation distributes the mechanical loads differently, redirecting forces along the transverse axis rather than concentrating them vertically on the sidewall structure, thereby reducing the burden on the sidewall while maintaining secure attachment.
Solution Approach 2:
The fixing sections are pre-positioned on the wall parts during manufacturing, allowing for optimized load distribution paths. This preliminary configuration ensures that mechanical loads are efficiently transferred to the floor panel through the floor connection, minimizing the stress on the sidewall structure.

AI summary
A cabin monument for an aircraft includes a floor panel, which forms a base surface of the cabin monument, and a surrounding sidewall which defines an interior space of the cabin monument. The surrounding sidewall is assembled from a first wall part and a second wall part which is coupled to this. Provision is made on at least one of the wall parts for a fixing section which is overlapped by the floor panel. Also described is an aircraft which features such a cabin monument.
