Aircraft Seat Support Device Segmentation for Repairability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft seat support devices lack flexibility and modular functionality, particularly in terms of component interchangeability and adaptability to varying passenger needs, with limited ability to dissipate forces and accommodate additional components.
Innovation Solution
The aircraft seat support device features a separable base and cover unit configuration, allowing for easy detachment and reconfiguration, with a backrest bridge design that can partially bridge the backrest unit, incorporating storage cavities, receiving units, and supply access units to accommodate various components, including electronic and mechanical accessories, and adjustable dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the aircraft seat support unit is designed as a single coherent piece, then structural integrity is maintained, but flexibility and ease of repair are reduced
Solution Approach 1:
The aircraft seat support unit is divided into separate base unit and cover unit components that can be detached from each other. This segmentation allows the cover unit to be easily removed and replaced without affecting the base unit, significantly improving ease of repair while maintaining structural integrity through proper connection interfaces between the segments
2Ease of manufacture
If the aircraft seat support unit is designed as a single coherent piece, then manufacturing simplicity is maintained, but adaptability and modular functionality are reduced
Solution Approach 1:
The support unit is segmented into base unit and cover unit that can be manufactured separately using standardized processes, then assembled through connection interfaces. This modular approach enables greater adaptability and versatility while keeping individual component manufacturing relatively simple
Solution Approach 2:
The base unit and cover unit are designed as universal modular components that can be used in different configurations and applications. The connection interface between base and cover units allows for multiple assembly variations, enhancing adaptability while maintaining manufacturing efficiency through standardized parts
3Stability of the object's composition
If the aircraft seat support unit is designed as a single coherent piece, then component stability is maintained, but ease of operation for component replacement is reduced
Solution Approach 1:
The support unit is divided into detachable base unit and cover unit with connection interfaces designed for easy engagement and disengagement. This segmentation enables simple operational replacement of the cover unit while maintaining stable composition when assembled, as the connection interfaces ensure secure attachment during use
