Seat Back Electronic Device Holder With Folding Shelf And Sliding Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic device holders are not suitable for seat backs, as they are not securely attachable, not compact enough for confined spaces, and unable to accommodate various device sizes or adjust viewing angles.
Innovation Solution
An electronic device holder with a base fixed to the seat back, a folding shelf rotatably attached via pivot members, and a sliding member that forms an angle with the shelf to securely hold devices of different sizes, allowing adjustable viewing angles and compact stowage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional electronic device holders are used, then they can hold electronic devices, but they are not securely attachable to seat backs and not compact enough for confined spaces
Solution Approach 1:
The holder is divided into separate functional components: a base for secure attachment to the seat back, a rotatable shelf for holding devices, and a sliding member for adjustment. This segmentation allows each component to be optimized independently, enabling secure attachment mechanisms in the base while keeping the overall structure compact when not in use.
Solution Approach 2:
The holder incorporates dynamic elements including a rotatable shelf that can pivot between stowed and use positions, and a sliding member that moves along rails to adjust device positioning. These dynamic features allow the holder to transform from a compact stowed state to an expanded functional state, providing secure attachment and device holding capabilities only when needed.
2Adaptability or versatility
If conventional electronic device holders are used, then they can hold devices, but they cannot accommodate various device sizes or adjust viewing angles
Solution Approach 1:
The holder is designed with universal adaptability through the combination of a rotatable shelf and sliding member that can accommodate various device sizes and types. The shelf can rotate to different angles and the sliding member can move to different positions, allowing the same structure to hold smartphones, tablets, or other electronic devices of varying dimensions without requiring multiple specialized holders.
Solution Approach 2:
The dynamic rotatable shelf and sliding member enable the holder to adapt to different device sizes and viewing angle requirements. The shelf rotation provides viewing angle adjustment, while the sliding member movement accommodates different device dimensions, all within a relatively simple mechanical structure consisting of rails, pivot members, and basic moving components.
3Ease of operation
If a folding shelf is rotatably attached to hold devices, then viewing angle adjustment is enabled, but the structure becomes more complex
Solution Approach 1:
The viewing angle adjustment function is segmented into a separate rotatable shelf component with its own pivot members, independent from the base attachment mechanism. This segmentation allows the viewing angle adjustment to be implemented using simple pivot connections without complicating the secure attachment system, maintaining ease of operation while controlling overall structural complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device holder securely holds and adjusts electronic devices of various sizes, providing a comfortable viewing angle and compact storage, suitable for use on seat backs in vehicles and other settings.
Implementation Method 1
a spring having a first end attached to the base and a second end attached to the sliding member. The sliding member is automatically retracted to the stowed position by a spring force when the upper flange is moved away from the electronic device.
Implementation Method 2
a coil spring attached to the rail and the sliding member, respectively. The coil spring may be disposed adjacent to a top end of the rail and configured to provide a tension to move the sliding member downward.
Implementation Method 3
the first pivot member may include two gears that engage with each other to provide an amount of resistance to damp motion of the folding shelf

AI summary
An electronic device holder disposed on a seat back comprises a base fixed to the seat back;a folding shelf rotatably attached to the base via first and second pivot members and configured to be rotated between a stowed position and a use position; and a sliding member attached to the base and configured to be moved upward and downward. The folding shelf includes an upper surface; and a plurality of retaining lips extending from the upper surface to form a plurality of recesses. The folding shelf and the sliding member form an angle in the use position so as to hold an electronic device between one of the recesses and a free end of the sliding member in the use position.
