Aircraft Monument Sub-Structure for Load Carrying Partition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional aircraft cabin monument attachments require numerous brackets and hard points, leading to increased weight, lengthy certification processes, and limited customization options, as each design variation necessitates separate certification and re-certification, which is time-consuming and expensive.
Innovation Solution
A standardized aircraft monument support sub-structure is integrated into the cabin monuments, allowing them to be attached directly to a load-carrying partition wall with a lattice structure, eliminating the need for brackets and tie rods, and enabling standardized certification through predetermined attachment points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional brackets and hard points are used to attach monuments to the cabin floor, then the monuments can be securely attached, but the weight of the aircraft increases and the certification process becomes lengthy and expensive
Solution Approach 1:
The patent combines the monument attachment system with the existing load-carrying partition wall structure. The sub-structure integrates attachment mounts directly into the partition wall framework, merging two separate systems (monument support and partition wall) into one unified structure. This eliminates the need for separate brackets and hard points on the cabin floor, reducing overall weight while maintaining secure attachment through the standardized sub-structure interface.
2Reliability
If conventional brackets and tie rods are used for monument attachment, then secure mounting is achieved, but the device complexity increases and automation becomes difficult
Solution Approach 1:
The patent creates a universal sub-structure with standardized attachment mounts that can accommodate various monument configurations and customization requirements. The standardized interface design allows different monument types (lavatories, galleys, cockpit doors) to use the same attachment system, reducing device complexity by eliminating the need for custom brackets and tie rods for each monument variation. This universal interface enables automation and simplifies installation procedures.
3Adaptability or versatility
If custom brackets are designed for each monument customization, then specific design requirements are met, but the certification process becomes lengthy and expensive
Solution Approach 1:
The patent performs preliminary action by pre-certifying the standardized sub-structure attachment system before actual monument installation. The sub-structure with standardized attachment mounts is designed and certified in advance to accommodate various monument configurations. This preliminary certification of the universal attachment system eliminates the need for separate re-certification of each customized monument design, significantly reducing certification time and costs while maintaining adaptability to different monument variations.
4Reliability
If numerous brackets are used to attach monuments at various points, then attachment reliability is improved, but the quantity of components increases and installation becomes more complex
Solution Approach 1:
The patent extracts the attachment function from multiple separate brackets distributed throughout the monument structure and consolidates it into a unified sub-structure with standardized attachment mounts. Instead of using numerous individual brackets at various points, the design removes these redundant components and replaces them with a single integrated sub-structure that provides all necessary attachment points through standardized interfaces, reducing component quantity while maintaining or improving attachment reliability.

AI summary
A sub-structure for an aircraft cabin monument is disclosed. The sub-structure includes a plurality of mounting attachment points for supporting a mount to engage with a corresponding mounting attachment point on a lattice structure of a load carrying partition wall. The aircraft cabin monument is supported by the load carrying partition wall through the sub-structure, supporting a substantial weight of the monument, and relieving the cabin floor from supporting the load and weight of the aircraft cabin monument.
