Adjustable tablet device holder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional exhibition racks for mobile tablet devices lack security measures, making them vulnerable to theft, as they do not provide adequate protection against displacement of adjustable support arms, which can be exploited to steal the devices.
Innovation Solution
An adjustable tablet device holder with a holder body and an adjustment mechanism featuring clamping plates, a transmission gear set, and a locking system that allows for secure adjustment and locking of mobile tablet devices of various sizes, preventing theft by locking the clamping plates in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional exhibition racks are simply designed for holding mobile tablet devices without security measures, then the device holder structure is simple and easy to manufacture, but the tablets are vulnerable to theft and displacement
Solution Approach 1:
The holder is divided into multiple independent clamping plates that can be adjusted and locked separately. Each clamping plate is a discrete component that can be positioned independently to secure different parts of the tablet device, providing segmented security protection while maintaining manufacturing simplicity.
Solution Approach 2:
The holder provides preliminary security by pre-positioning multiple clamping plates in strategic locations around the tablet. The plates are arranged in advance to cover potential vulnerability points, and can be locked into position before theft attempts occur, preventing displacement rather than reacting to it.
2Adaptability or versatility
If adjustable support arms are made retractable and multi-segment for flexibility, then the holder can accommodate different tablet sizes, but gaps in the transmission gear set allow violent biasing and create security vulnerabilities
Solution Approach 1:
The holder employs dynamic adjustability through rotatable turntables that can be freely positioned to accommodate tablets of various sizes. The clamping plates can be rotated into different angular positions and locked, providing continuous adaptability rather than fixed discrete positions, while maintaining security through the locking mechanism.
Solution Approach 2:
The turntable acts as an intermediary mechanism between the adjustment requirement and the security requirement. It provides smooth, controlled adjustment of the clamping plates to different positions while the locking mechanism mediates the security aspect, preventing violent biasing by securing the turntable in its locked state.
3Reliability
If a locking mechanism is added to secure tablets against theft, then security protection is improved, but the adjustment mechanism becomes more complex and difficult to operate
Solution Approach 1:
The holder employs self-service locking where the user simply rotates the clamping plates to the desired position and engages the lock, which then secures both the adjustment position and the tablet simultaneously. The system serves itself by integrating the locking function directly into the adjustment mechanism, eliminating the need for separate locking operations.
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 adjustable and lockable tablet device holder effectively secures mobile tablet devices of different sizes, preventing theft by allowing precise adjustment and locking, thus enhancing security and protection against unauthorized removal.
Implementation Method 1
a transmission gear set consisting of two gears and mounted on the stub axle for synchronous rotation with the turnable. Each clamping plate further comprises a tooth rack longitudinally extended along one lateral side of the respective elongated extension wing plate portion and meshed with the transmission gear set.
Implementation Method 2
lockable to the locating plate of the holder body by a lock to prohibit the clamping plates from displacement

AI summary
An adjustable tablet device holder includes a holder body including an arched sliding slot located in the back side and a locating plate extended from the back side adjacent to the arched sliding slot, and an adjustment mechanism including a turnable mounted in the holder body and having a position-limit rod extended out of the arched sliding slot and movable between the two ends of the arched sliding slot to rotate the turnable and lockable to the locating plate by a lock to stop the turntable from rotation and four clamping plates vertically and horizontally mounted in four sides and defining a clamping space for holding a mobile tablet device and movable inwardly and outwardly to adjust the horizontal width and vertical height of the clamping space upon rotation of the turnable.
