Screw-Based Mounting for Tablet Extension Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tablet apparatuses face challenges in securely and easily attaching extension portions, such as pen holders, due to the limitations of magnet-based mounting systems, which can lead to instability and limited functionality.
Innovation Solution
A position input apparatus with a body portion and an extension portion, where the body portion has a side surface with a screw hole and the extension portion includes a screw with a shaft and head, allowing for easy and firm attachment by screwing into the body portion's screw hole, enabling secure and removable attachment without interfering with the operation surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a magnet is used to install the electronic pen on the outer frame side surface, then the electronic pen can be mounted without a dedicated mount portion, but the mounting stability is poor and the electronic pen may easily separate
Solution Approach 1:
The patent replaces the magnetic mounting system with a screw-based mechanical fastening system. The screw penetrates the outer frame and engages with a threaded hole in the inner frame, providing reliable mechanical connection that eliminates the instability inherent in magnetic mounting while maintaining the ability to mount various extensions.
Solution Approach 2:
The patent divides the mounting system into distinct components: the screw as the fastening element, the outer frame as the mounting structure, and the inner frame as the receiving structure. This segmentation allows each component to perform its specific function optimally, with the screw providing secure attachment while the frame structures provide structural support.
2Area of stationary object
If the outer frame width is reduced to widen the operation surface, then the operation surface area increases, but the outer frame becomes too narrow to accommodate a mount portion on its upper surface
Solution Approach 1:
The patent moves the mounting function from the horizontal plane (upper surface of outer frame) to the vertical dimension (side surface of outer frame). By providing a screw hole on the side surface of the outer frame, the system enables mounting capability without requiring horizontal space on the already-constrained outer frame width.
Solution Approach 2:
The screw-based mounting system on the outer frame side surface serves multiple functions: it provides secure attachment for the electronic pen, allows for easy removal and reattachment, and can potentially accommodate various other extensions beyond just the electronic pen, making the mounting system universally applicable to different devices.
3Adaptability or versatility
If various items are attached to the outer frame part, then the functionality of the tablet apparatus can be expanded, but the attachment method must be both easy and firm
Solution Approach 1:
The screw-based mounting system enables users to independently attach and detach various extensions without requiring special tools or assistance. The screw can be manually operated to secure items firmly while also allowing easy removal when needed, providing self-service capability for functionality expansion.
