Convertible Aircraft Monument with Switchable Cooling Compartment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft galleys occupy valuable cabin space, limiting the number of passenger seats due to the need for dedicated refrigeration systems for perishable food and beverages, which may not meet varying demands on different flights, and there is a lack of flexible storage solutions for both perishable and non-perishable items.
Innovation Solution
The implementation of convertible monuments in aircraft cabins that can be used as either refrigerated compartments or non-cooled storage spaces, equipped with a plumbing-free chiller that can be easily retrofitted, allowing for flexible use based on demand, with the chiller positioned at the rear to minimize space impact and include adjustable panels for varying compartment sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated refrigerated compartments are provided in aircraft galleys, then perishable food and beverages can be stored, but cabin space is reduced limiting passenger seat capacity
Solution Approach 1:
The monument is designed to serve dual functions: as a refrigerated compartment when cooling is required, and as a non-cooled storage space when cooling is not needed. This multi-functionality allows the same space to adapt to varying operational requirements, maximizing cabin space utilization while ensuring perishable storage capability when necessary.
Solution Approach 2:
The system incorporates a convertible monument with adjustable cooling capability. The refrigeration system can be activated or deactivated based on flight requirements, allowing dynamic adaptation between cooled and non-cooled storage modes. This dynamic configuration optimizes space usage while maintaining reliability for perishable storage when needed.
2Quantity of substance
If additional galley space is provided for extra food and beverage storage, then catering capacity is increased, but the number of passenger seats must be reduced
Solution Approach 1:
The convertible monument provides universal storage capability that can function as either a refrigerated compartment or a non-cooled storage space. This allows the aircraft to maximize food and beverage storage capacity across different flight scenarios without permanently dedicating space that would reduce passenger seating.
Solution Approach 2:
The system allows change in operational parameters by activating or deactivating the refrigeration system in the monument. When additional perishable storage is needed, the cooling system is activated; when not needed, it operates as non-cooled storage, thus optimizing both storage quantity and space utilization.
3Adaptability or versatility
If refrigeration systems are installed in convertible monuments, then cooling capability is added, but device complexity increases
Solution Approach 1:
The refrigeration system is extracted as a separate, modular unit that can be independently controlled and maintained. This allows the cooling functionality to be added to the monument without integrating complex systems throughout the entire galley, thereby adding adaptability while minimizing overall system complexity.
4Volume of moving object
If galleys are minimized to maximize passenger seats, then cabin space is optimized, but sufficient storage for perishable items cannot be guaranteed
Solution Approach 1:
By making the monument convertible between cooled and non-cooled modes, the system ensures that perishable storage capability is available when needed without permanently allocating dedicated refrigerated space that would reduce cabin volume. The same space adapts to different requirements.
Solution Approach 2:
The dynamic cooling capability allows the monument to provide refrigeration services on-demand based on flight requirements. This ensures reliable perishable storage capability is maintained while minimizing the permanent space allocation, thus optimizing cabin space while guaranteeing storage reliability when needed.

AI summary
A convertible monument (16) has a plurality of monument walls (100) defining sides (118, 120), a front (114), and a rear (116) of the monument surrounding a chamber (102) defined by the monument walls. The convertible monument has a closet component (124) positioned in the chamber for supporting non-perishable items in the chamber. The chamber has a convertible area (130) convertible between a cooling compartment (132) and an uncooled compartment (134). A chiller (52) is positioned in the chamber proximate the convertible area. The chiller is configured to supply cool air to the cooling compartment when operated for cooling perishable items stowed in the cooling compartment. The convertible area is used as an uncooled compartment for stowing non-perishable items when the chiller is inactive.
