Touch Screen Locking via Stylus Mount Nesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable communication devices with touch screens face issues due to unwanted screen touches when not in use, leading to malfunction and aesthetic degradation from frequent on/off operations of external locking units.
Innovation Solution
A touch-screen locking unit that automatically turns on/off based on the attachment/detachment of a stylus pen, integrated on the inner side of the device's main body housing, using various mechanisms such as dome keys, button keys, magnetic members, or sensors to control the locking state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a touch-screen locking unit is provided on the outer portion of the portable communication device, then the touch screen can be locked to prevent unwanted operations, but the aesthetics of the device is degraded and the locking unit may be deformed or defective due to frequent ON/OFF operations
Solution Approach 1:
The locking unit is integrated into the mounting groove structure where the stylus pen is attached. The locking unit is positioned inside the main body housing, nested within the existing structural components rather than being an external addition. This nesting approach maintains the device's aesthetic appearance while providing the locking function.
Solution Approach 2:
The locking unit is combined with the mounting groove and stylus pen attachment mechanism. The locking unit shares the same structural space and operational mechanism as the stylus pen mounting, merging multiple functions into a single integrated component rather than having separate external locking and mounting units.
2Reliability

The locking unit shares the same structural space and operational mechanism as the stylus pen mounting, merging multiple functions into a single integrated component rather than having separate external locking and mounting units.
Solution Approach 2:
The locking unit serves multiple functions: it locks the touch screen to prevent unwanted operations, and it is integrated with the stylus pen mounting mechanism. This multi-functionality reduces the need for separate components and simplifies the overall device structure while maintaining reliable locking functionality.
3Ease of operation
If an external locking unit is provided on the portable communication device, then the touch screen can be locked, but the device requires additional components that may deform or defect due to frequent operations
Solution Approach 1:
The locking unit is automatically controlled by the attachment and detachment of the stylus pen itself. When the stylus pen is attached, the locking unit is automatically activated; when detached, it is automatically deactivated. This self-service mechanism eliminates the need for separate control operations and reduces wear on the locking mechanism.
Solution Approach 2:
The locking state is determined in advance by the stylus pen attachment action. The mere act of attaching the stylus pen preliminarily sets the locking state without requiring additional locking operations, reducing the frequency of locking unit actuation and improving durability.

AI summary
A portable communication device having a touch-screen locking unit that can prevent operation of the touch screen due to an unwanted screen touch is disclosed. The device comprises a main body housing having a touch screen. A mount is formed in the main body housing. An input unit is attached to or detached from the mount. A locking unit is provided on the mount and turns on/off a locking state of the touch screen according to attachment/detachment of the input unit. The locking state of the touch screen can be automatically set to an ON/OFF state by attaching/detaching a stylus pen to/from a mounting groove. When the touch screen is carried or kept, a touch screen operation or change according to an external environment can be prevented.
