Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft seat assemblies face challenges in balancing structural integrity and weight reduction while meeting industry regulations and cost considerations, with existing designs often compromising on either performance or cost.
Innovation Solution
The proposed aircraft seating assembly includes a seat pan, connection frame, and mounts that allow for flexibility and removability, along with a tilt system and retention system, to enhance passenger comfort and structural compliance while maintaining a lightweight and cost-effective design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional aircraft seat assemblies use heavy structural components to meet safety regulations, then structural integrity and safety are improved, but weight increases
Solution Approach 1:
The seat assembly is divided into modular components including the seat pan, backrest, connection frame, and mounting structure. Each component can be independently designed, manufactured, and tested to optimize the strength-to-weight ratio. The segmentation allows for targeted reinforcement only where structurally necessary while using lighter materials in non-critical areas.
Solution Approach 2:
The patent utilizes composite materials for the seat pan and backrest structures, combining materials with different properties to achieve both strength and weight reduction. The composite construction allows for optimized structural integrity while significantly reducing the overall weight compared to traditional solid metal or wood constructions.
2Reliability
If aircraft seats use complex mounting systems to ensure safety and compliance, then reliability is improved, but device complexity increases
Solution Approach 1:
The mounting system is designed as a separate, extractable component that can be independently installed and removed. The connection frame and mounting brackets are distinct from the seat pan and backrest, allowing for simplified assembly and maintenance. This extraction principle reduces overall system complexity by isolating the complex mounting functions into dedicated components.
Solution Approach 2:
The connection frame and mounting structure are designed with universal features that can accommodate different installation configurations and aircraft types. The standardized mounting interfaces and adjustable connection points allow the same basic structure to serve multiple functions and installation scenarios, reducing the need for multiple specialized components.
3Strength
If aircraft seats are designed as integrated units, then structural strength is improved, but ease of repair and maintenance deteriorates
Solution Approach 1:
The seat is segmented into independently removable components including the seat pan, backrest, and mounting structure. This segmentation maintains structural integrity when assembled while allowing individual components to be easily removed and replaced for maintenance or repair without affecting the entire seat assembly.
Solution Approach 2:
The modular design enables individual components to be discarded (removed from service) and recovered (repaired or replaced) independently. Worn or damaged components can be selectively replaced while retaining functional parts, simplifying maintenance operations and reducing overall repair time and cost.
