Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current input modules in notebook computers, such as keyboards and single touch panels, are inadequate for providing a convenient and fast operation experience, especially during high-performance tasks like gaming or drawing, and adding additional input modules complicates space configuration and user convenience.
Innovation Solution
A portable electronic device with multiple touch panels and a sliding keyboard module that can turn specific touch panels on or off based on its position, using detecting modules like magnetic sensing or optical sensing to prevent inadvertent touches and enhance user input methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional input modules are added to the notebook computer, then input functionality is improved, but space configuration and operational convenience are worsened
Solution Approach 1:
The touch panel serves multiple functions: it acts as both a display interface and an input device with different interaction modes (first touch panel mode for cursor control, second touch panel mode for direct manipulation). The keyboard module also serves dual purposes as both a physical keyboard and a positioning mechanism for selecting touch panel modes, eliminating the need for separate input devices and maintaining operational convenience.
2Adaptability or versatility
If multiple touch panels are provided, then input methods are diversified, but risk of inadvertent touch increases
Solution Approach 1:
The system dynamically switches between different touch panel modes (first and second touch panel modes) based on the keyboard module's position. The detecting module continuously monitors the keyboard module's location and automatically activates the appropriate touch panel mode, making the system adaptive to user intent and preventing inadvertent touches by ensuring only the intended touch panel is active.
Solution Approach 2:
The detecting module provides real-time feedback on the keyboard module's position to the processing unit, which then adjusts the touch panel mode accordingly. This feedback mechanism ensures that the system responds to the user's positioning actions and automatically configures the appropriate input mode, preventing inadvertent touches by keeping only the relevant touch panel active.
3Adaptability or versatility
If keyboard module is made slidable, then touch panel selection flexibility is improved, but device complexity increases
Solution Approach 1:
The invention merges the keyboard module's physical positioning function with the touch panel mode selection function. The keyboard module's slidable position directly determines which touch panel mode is active, combining mechanical positioning with logical control into a single integrated mechanism, thereby improving flexibility without proportionally increasing overall device complexity.

AI summary
A portable electronic device includes a first body and a second body. The second body includes a processing unit, and a first touch panel, a second touch panel, a keyboard and at least one detecting module electrically connected to the processing unit, respectively. The keyboard is slidably disposed above the second touch panel, and the detecting module is adapted to detect a position of the keyboard. When the keyboard is located at a first position, the keyboard module covers the second touch panel, and the detecting module transmits a first signal to the processing unit so that the first touch panel is turned on. When the keyboard is located at a second position, the keyboard exposes the second touch panel, and the detecting module transmits a second signal to the processing unit so that the first touch panel is turned off. A touch panel controlling method of the portable electronic device is further provided.
