Adjustable Tablet Holder Locking Mechanism
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 create gaps allowing theft.
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 displacement and theft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional exhibition racks are designed with adjustable support arms for holding different sizes of mobile tablet devices, then the adaptability of the device holder is improved, but the security against theft deteriorates due to gaps in the transmission gear set that allow violent biasing and device removal
Solution Approach 1:
The patent applies preliminary anti-action by implementing a locking mechanism that proactively prevents theft before it can occur. The lock engages with the transmission gear set to block any violent biasing or unauthorized movement of the adjustable support arms, countering potential theft attempts before they can exploit the gaps in the gear set.
Solution Approach 2:
The patent uses an intermediary element (the lock) that mediates between the adjustable support arm mechanism and the external environment. This lock acts as a security barrier that allows normal adjustment functionality while blocking malicious interference, thus resolving the contradiction between adaptability and security.
2Ease of manufacture
If conventional exhibition racks provide simple holding structures for mobile tablet devices, then the device complexity is reduced and ease of manufacture is improved, but the protection against violent biasing and theft deteriorates
Solution Approach 1:
The patent applies dynamics by implementing a lock that can transition between locked and unlocked states. When locked, the transmission gear set is secured against violent biasing; when unlocked, the adjustable support arms can be freely adjusted. This dynamic locking mechanism adds security without permanently complicating the structure.
Solution Approach 2:
The patent changes the state parameter of the transmission gear set from unlocked (vulnerable) to locked (secured). The lock modifies the mechanical state of the system, transforming it from a simple holding structure to a secured mechanism that resists violent biasing while maintaining ease of manufacture through the simple addition of the locking component.
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 holder effectively secures mobile tablet devices by allowing adjustable clamping to fit different sizes and locking them in place, significantly reducing the risk of theft and providing enhanced protection against damage.
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.
