Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft cabin support structures for flight attendant seats lack flexibility and adaptability to different aircraft configurations, requiring additional authorization and complicating the installation process, while also failing to provide adequate safety and separation between regions.
Innovation Solution
A support structure with vertically and horizontally arranged elements, featuring lattice struts and adaptable fastening points, allowing for flexible attachment to various aircraft structures and enabling the integration of cabin elements like dividing walls, ensuring compliance with international aviation regulations and dynamic loading requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed support structure is used for flight attendant seats, then the structural stability is ensured, but the adaptability to different aircraft configurations is reduced
Solution Approach 1:
The support structure is divided into modular components including vertical elements, horizontal elements, and lattice struts that can be independently configured. This segmentation allows the same basic structure to be adapted to different aircraft layouts while maintaining structural integrity through standardized connection interfaces.
Solution Approach 2:
The support structure is designed with universal fastening points and standardized lattice strut configurations that can serve multiple aircraft types and cabin layouts. The same basic structure can accommodate different numbers of flight attendant seats and be positioned at various locations along the aircraft cabin, providing multi-functionality across different operational contexts.
2Adaptability or versatility
If customized support structures are designed for each aircraft configuration, then the adaptability is improved, but the device complexity and development time increase
Solution Approach 1:
By segmenting the support structure into standardized modules (vertical elements, horizontal elements, lattice struts), the design complexity is reduced while maintaining customization capability. Each module can be independently selected and combined to match different aircraft configurations without requiring complete redesigns.
Solution Approach 2:
The support structure allows for parameter adjustments such as the number of vertical elements, spacing of fastening points, and configuration of lattice struts to match different aircraft requirements. These parameter changes can be made within a standardized design framework, avoiding the need for completely custom designs for each configuration.
3Ease of operation
If multiple fastening points are provided for flexible attachment, then the ease of installation is improved, but the device complexity increases
Solution Approach 1:
The fastening points are designed with universal connection interfaces that can accommodate different attachment configurations using the same basic hardware. This universality allows multiple fastening points to be used without proportionally increasing device complexity, as the same standardized components serve multiple attachment locations.
