PSU Pod Assembly Integrated with Overhead Bin Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial aircraft face challenges in maximizing overhead stowage volume and passenger comfort within weight and space constraints, as existing overhead storage bin designs often result in redundant paneling, reduced stowage capacity, and limited integration of essential systems like environmental control and lighting.
Innovation Solution
The pivot bin assembly employs a 'clamshell design' with a single-piece bucket and upper housing that pivots to close, minimizing overlap and redundant parts, integrating ECS ducting and electrical components, and includes a PSU pod assembly with adjustable lighting and ventilation, allowing for increased stowage volume and passenger-specific lighting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If traditional overhead storage bin designs are used, then structural support and system integration are achieved, but stowage volume is reduced and weight is increased due to redundant paneling
Solution Approach 1:
The patent combines the overhead storage bin structure with the PSU pod assembly into an integrated unit. The bin sides extend downward to form the PSU pod housing, eliminating the need for separate paneling structures. This merging of functions directly increases stowage volume while removing redundant components that add weight and complexity.
2Adaptability or versatility
If separate PSU panels are installed above seats, then system integration is achieved, but headroom is reduced and cabin feel is more confined
Solution Approach 1:
The PSU pod is nested within the overhead bin structure itself. The bin sides extend downward to form the housing for the PSU pod, creating a nested configuration where one structure contains another. This eliminates the need for separate PSU panels above the seats, thereby preserving headroom and creating a more open cabin feel while maintaining full system integration.
3Adaptability or versatility
If multiple separate components are used for overhead bins and PSU, then functional requirements are met, but weight is increased
Solution Approach 1:
The overhead storage bin and PSU pod assembly are merged into a single integrated structure. The bin sides serve dual purposes as both storage structure and PSU housing, eliminating the need for separate components. This consolidation reduces the total weight of the assembly while maintaining all required functions including storage, lighting, ventilation, and electrical outlets.
4Ease of manufacture
If conventional overhead bin design is used, then manufacturing simplicity is maintained, but stowage capacity is limited
Solution Approach 1:
The overhead bin is designed with a single-piece bucket construction that segments the structure into functional zones. The bucket is formed as one continuous piece that extends downward to integrate with the PSU pod, creating modular segments that are easy to manufacture yet maximize stowage capacity. The single-piece construction maintains manufacturing simplicity while the extended vertical integration increases usable volume.
