Passenger Seat Holding Device With Break-Proof Translucent Shutter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional media reproducing apparatus attached to passenger seats in transportation vehicles do not meet safety standards as they can be damaged in accidents, posing a risk to passengers, and are not allowed for use during critical phases like starting or landing.
Innovation Solution
A holding device with a detachable adapter and a protective shutter made of break-proof, translucent material that securely attaches to the passenger seat, allowing the media reproducing apparatus to be clamped and protected from impact, while enabling visibility and use during emergencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a media reproducing apparatus is attached to the passenger seat, then the passenger can access video and audio contents during the journey, but the apparatus may be damaged by impinging objects in case of accident or emergency landing, posing a risk of injury to the passenger
Solution Approach 1:
A protective shutter made of break-proof material (polycarbonate or acrylic) is introduced as an intermediary between the passenger and the media reproducing apparatus. The shutter can be transparent or translucent, allowing visual access to the screen while physically protecting the apparatus from impinging objects during accidents or emergency landings.
Solution Approach 2:
The protective shutter is designed as a separate, movable component that can be opened or closed independently. It is guided by rails and can be displaced between an open position (allowing full access to the apparatus) and a closed position (providing protection while maintaining screen visibility).
2Object-affected harmful factors
If a protective shutter is provided to protect the media reproducing apparatus, then the apparatus is protected from damage, but the passenger's access to operate or exchange the apparatus is restricted
Solution Approach 1:
The protective shutter is designed as a dynamic, movable component rather than a fixed barrier. It can be displaced along guided rails between an open position (providing full access for operation, exchange, or removal of the apparatus) and a closed position (providing protection). This dynamic design allows the system to switch between protection and accessibility modes as needed.
3Object-affected harmful factors
If a protective shutter made of break-proof material is used, then the apparatus is protected from impact, but the passenger cannot see through the shutter to view the screen
Solution Approach 1:
The protective shutter is made from transparent or translucent materials (such as polycarbonate or acrylic) that allow light to pass through. This enables the passenger to view the screen contents through the closed shutter while still maintaining the protective function against impact. The material properties are specifically selected to balance optical transparency with mechanical strength.

AI summary
A passenger seat including a holding device for a media reproducing apparatus, includes a base holding fixture attached to a backrest of said passenger seat, at least one adapter adapted to be detachably connected with said base holding fixture, said adapter being configured for holding said media reproducing apparatus at said base holding fixture, a standardized electronic interface to the power supply of said media reproducing apparatus, and a protective shutter fixedly connected with said backrest. The protective shutter is adapted to be moved from an open position in which access to said adapter and said media reproducing apparatus is allowed, into a closed position in which said media reproducing apparatus and said adapter are completely covered by said protective shutter. The protective shutter is of break-proof configuration and made at least partially from a translucent material such that a screen is visible through said protective shutter in the closed position.
