Seatback Tablet Support Shelf for Stable Transit Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apparatuses for holding portable electronic devices in transit systems are impractical due to instability, limited compatibility with various device form factors, and inability to securely attach to surfaces, leading to user fatigue and potential device damage.
Innovation Solution
A seatback tray table apparatus with a back member, connecting members, side members, and fastening members that can be adjusted and securely attached to a seatback, allowing for flexible viewing angles and secure device holding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing apparatuses use fasteners such as magnets, hook-and-loop materials, hangers, or suction devices to hold portable devices, then the device can be attached to a surface, but the attachment is insecure and impractical on transit systems because these fasteners rarely adhere to surfaces properly
Solution Approach 1:
The patent introduces a tray table as an intermediary structure between the seatback and the portable device. The tray table provides a stable, flat surface that can reliably support the device, eliminating the need for direct attachment fasteners that fail on various surfaces. The tray table acts as a mediator that transforms the unstable seatback surface into a stable viewing platform.
Solution Approach 2:
The apparatus is designed as a disposable or recyclable structure that can be easily attached and detached. The tray table and supporting members are intended for single-use or limited-use scenarios in transit, where durability is less critical than ease of deployment and disposal after the journey.
2Reliability
If apparatuses grip the device with pressure to secure it, then the device can be held firmly, but the pressure can be too weak resulting in device disconnection or too strong resulting in device damage
Solution Approach 1:
The cavity design incorporates cushioning elements that distribute pressure evenly across the device surface. The flexible or compliant materials in the cavity provide protective cushioning before any potential damage can occur, ensuring the device is secured firmly without concentrated pressure points that could cause damage.
3Reliability
If apparatuses are designed to accommodate specific device sizes such as four-inch smart phones or ten-inch tablets, then the holding structure can be optimized for that form factor, but the apparatus becomes unusable with other device form factors
Solution Approach 1:
The tray table apparatus is designed with universal dimensions and features that can accommodate various portable device form factors. The cavity size, tray table dimensions, and supporting members are configured to work with smartphones, tablets, and other portable devices of different sizes, making the apparatus multi-functional and adaptable.
4Ease of operation
If existing stands are designed for horizontal surfaces, then the device can sit erect, but the stands are impractical on transit systems due to lack of stable horizontal surfaces, large potential for movement, and limited space
Solution Approach 1:
The apparatus transitions from a static stand design to a dynamic structure that adapts to the moving transit environment. The tray table can be adjusted and repositioned, and the supporting members can accommodate movement and vibration, making the system dynamic rather than rigid and static.
Solution Approach 2:
Instead of relying on a horizontal surface for stability, the apparatus utilizes the vertical dimension by attaching to the seatback. The tray table extends horizontally from this vertical attachment point, creating a stable platform without requiring a pre-existing horizontal surface.
