Modular Video Display Cassette for Aircraft Seats
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current in-flight entertainment systems face challenges in providing a modular and easily installable video display unit that can be seamlessly integrated with aircraft seats, while also meeting Head Injury Criteria (HIC) standards and allowing for future upgrades without requiring costly recertification.
Innovation Solution
A modular video display unit cassette assembly that includes a cassette frame, a display, electronic components, and a delethalization cover, designed to be releasably mounted in a seatback mounting structure, with a large format video display and connectivity ports, and a modular design that allows for easy installation, removal, and upgrading without impacting HIC certification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a modular cassette assembly design is used, then ease of installation and upgrading is improved, but device complexity increases
Solution Approach 1:
The video display unit is divided into a modular cassette assembly that can be independently installed and removed from the seatback mounting structure. The cassette assembly includes the display, electronic components, and delethalization cover as a separable unit, enabling easy installation and upgrading without affecting the entire seat system.
Solution Approach 2:
The electronic components are extracted as separate replaceable modules within the cassette assembly. This allows individual electronic components to be upgraded or replaced without removing the entire display unit, facilitating maintenance and future upgrades while keeping the overall system structure simple.
2Adaptability or versatility
If a large format video display is used, then user experience is improved, but weight increases
Solution Approach 1:
The cassette assembly is designed with a releasable mounting system using removable fasteners, allowing the display to be dynamically installed or removed from the seatback. This dynamic design enables easy replacement of heavy large-format displays without permanent installation, improving user experience while managing weight through selective deployment.
3Ease of operation
If the cassette assembly is made releasably mounted, then ease of removal and upgrading is improved, but reliability decreases
Solution Approach 1:
The cassette assembly includes a delethalization cover that is pre-installed to cover sharp edges and potential hazards before the display is mounted in the seatback. This preliminary protective action ensures safety and reliability are established before the display enters service, while the fasteners remain designed for easy removal when needed.
4Ease of manufacture
If fasteners are received from the front of the aircraft seat, then ease of installation is improved, but device complexity increases
Solution Approach 1:
The mounting structure uses universal fasteners that can be accessed from the front of the seat and serve multiple functions: securing the cassette assembly during installation, holding it firmly during operation, and enabling easy removal when needed. This multi-functional fastening system simplifies the overall mounting structure by eliminating the need for separate mechanisms for different operational phases.
Data Source
AI summary
A video display unit cassette assembly includes a cassette frame, a display coupled to the cassette frame, one or more electronic components between the cassette frame and the display, and a delethalization cover coupled to the display. The one or more electronic components receive data content from a network and generate video signals provided to the display. The cassette assembly is sized and configured to be releasably mounted in an installed position in a mounting structure defined in a seatback of a vehicle seat.
