Solution Overview

Problem

Aircraft seat devices face challenges in optimizing space and weight requirements while maintaining functionality, particularly in transitioning between use and stowage positions.

Innovation Solution

The design incorporates a base body with pivotally connected plates that adjust through a hinge element and joint elements, allowing for significant depth extension changes between functional positions, enabling a compact stowage position and expanded use position, with a table surface that can be aligned parallel to the seat support plane.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a table device is integrated into the aircraft seat with extended depth for use position, then functionality and comfort are improved, but space requirements and weight increase

Engineering Contradiction:
ImprovefunctionalityVSAvoidspace requirements
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The table device is designed with dynamic depth extension capability, allowing it to change from a retracted state during flight to an extended state during landing/taxiing. The depth extension device includes movable elements that can protrude from the seat structure, transforming the table from a compact storage configuration to a functional extended configuration based on operational requirements.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the base body is designed with large depth extension for use position, then functional performance is improved, but space consumption in stowage position increases

Engineering Contradiction:
Improvefunctional performanceVSAvoidspace consumption
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The base body is segmented into multiple depth sections that can be independently adjusted. The depth extension device is divided into separate movable segments that can be extended or retracted independently, allowing the table to achieve functional depth when needed while maintaining a compact profile during stowage by retracting only the necessary extension segments.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If multiple adjustment mechanisms are added to achieve depth extension, then adaptability is improved, but device complexity increases

Engineering Contradiction:
ImproveadaptabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The depth extension device is merged with the existing table structure and support mechanisms. The extension mechanism integrates with the seat's current adjustment systems, sharing common components such as mounting structures, control systems, and structural supports, thereby reducing overall complexity despite adding adaptability functionality.

Inventive Principle:
Principle #5Merging (Combining)
