Sliding Positioning System for Portable Electronic Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable electronic devices with sliding keyboards face issues where hot keys are easily pressed by mistake, leading to unintended actions during data input, and the use of touch pens is inconvenient due to fixed attachment methods.
Innovation Solution
A portable electronic device with a sliding positioning system that allows multiple positioning locations between the first and second bodies, incorporating a magnetic component to automatically eject a touch pen for improved convenience, preventing accidental key presses by hiding the hot key area when the keyboard is in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the second body slides away from the first body to expose the keyboard area, then data input operation is enabled, but hot keys are easily pressed by mistake causing unintended actions
Solution Approach 1:
The sliding positioning device divides the sliding range into multiple distinct positions (first position, second position, third position). At the second position, the keyboard area is exposed while hot keys remain hidden, segmenting the visibility and accessibility of different input areas to prevent accidental presses during data input
Solution Approach 2:
Different areas of the device have different visibility states at the same time. The keyboard area can be exposed for data input while the hot keys remain hidden, creating local quality differences in accessibility that prevent unintended actions while maintaining ease of operation
2Strength
If the touch pen is fixed at the outside or inside of the casing in a fastening mode, then the touch pen is securely attached, but a user needs to take out the touch pen in a digging or picking mode which is inconvenient
Solution Approach 1:
The magnetic component automatically ejects the touch pen when the second body is at the third position (exposing hot keys), eliminating the need for manual retrieval. The system serves itself by using magnetic field changes to automatically deploy the touch pen when needed
Solution Approach 2:
The touch pen is pre-positioned inside the first body in a stored state. When the second body slides to the third position, the magnetic component automatically ejects the touch pen in advance before the user needs it, so the touch pen is already available when the user wants to use it
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 sliding positioning system effectively prevents accidental hot key presses and enhances user convenience by automatically deploying the touch pen, ensuring accurate data input and improved usability.
Implementation Method 1
A magnetic component is disposed in the second body... One end of the operation device is provided with a second magnetic component... When the second body is located at the third location, the second magnetic component and the first magnetic component are opposite to each other

AI summary
A portable electronic device includes a first body, a second body and a sliding positioning device. The first body includes a first operation area and a second operation area. The second body is slidable relative to the first body. The sliding positioning device is connected to the first body and the second body to position the second body at a plurality of locations relative to the first body. The second body hides the second operation area and exposes the first operation area when the second body is located at one of the locations.
