Modular Airline Seat Interface for Easy Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-flight entertainment systems face challenges in replacing non-functional user interface elements and upgrading to new technologies due to directly mounted components, which are difficult and costly to replace and upgrade.
Innovation Solution
A modular user interface system featuring a module carrier unit with standardized passenger interface modules that can be easily inserted and removed from sockets, allowing for simple replacement and configuration changes, including a communications interface and various modules such as RCA video, audio, and USB modules, with a common interface and locking mechanism for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If interface elements are directly mounted within seating elements, then structural integration is improved, but ease of repair and upgrading deteriorates
Solution Approach 1:
The interface system is divided into separate modular interface modules that can be independently removed and replaced. Each interface module contains specific interface elements (headphone jacks, video jacks, etc.) and can be detached from the seating element without replacing the entire seat structure, thereby maintaining structural integration while enabling easy repair and upgrading.
Solution Approach 2:
The interface modules are designed with dynamic characteristics allowing them to be easily installed and removed from the seating elements. This dynamic design enables flexible replacement of interface modules based on functional requirements or technological advancements, resolving the contradiction between stable structural integration and ease of repair.
2Stability of the object's composition
If interface elements are directly mounted within seating elements, then structural integration is improved, but adaptability to new technologies deteriorates
Solution Approach 1:
By segmenting the interface system into replaceable modules, the patent enables selective upgrading of interface modules to incorporate new technologies while the main seating structure remains stable. This allows the system to adapt to evolving technological standards without compromising structural integration.
Solution Approach 2:
The interface modules are designed with universal mounting interfaces that can accommodate different types and generations of interface elements. This universality allows the same mounting structure to support various technological configurations, enhancing adaptability while maintaining structural stability.
3Stability of the object's composition
If interface elements are directly mounted within seating elements, then structural integration is improved, but maintenance cost increases
Solution Approach 1:
Segmenting the interface system into replaceable modules reduces maintenance costs by allowing targeted replacement of only the faulty interface module rather than the entire seating element. This modular approach minimizes parts, labor, and downtime associated with repairs while preserving the integrated appearance and structure of the seat.
