Pivot Display Panel Overlap for Keypad Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile electronic devices with rotating planar panels fail to effectively combine a Qwerty keypad with a landscape widescreen display in a compact form, as they either obscure the keypad or display, or compromise on device height when transitioning between retracted and extended positions.
Innovation Solution
A mobile electronic device design featuring two hingeably connected planar panels that rotate 90°, maintaining overall height and allowing the panels to substantially overlap in retraction, with one panel housing a Qwerty keypad and the other a display screen, which can be obscured in retraction and exposed in extension, utilizing a pivot axis placement that ensures symmetry and compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If two planar panels are pivotally connected to allow 90° rotation for landscape display, then a widescreen display can be achieved, but the device height increases when extended
Solution Approach 1:
The first panel is received inside the hollow space of the second panel when in the retracted position, creating a nested configuration that maintains compact device height while allowing the panels to rotate for landscape display when needed
2Length of stationary object
If panels are arranged to overlap completely in retracted position for compactness, then device height is minimized, but the keypad or display cannot be accessed
Solution Approach 1:
The panels are made movable relative to each other through a pivot connection, allowing the device to transition dynamically between a compact retracted state with complete overlap and an extended state where the keypad becomes accessible, providing both compactness and usability
3Adaptability or versatility
If a Qwerty keypad is combined with landscape widescreen display, then typing capability is improved, but the device structure becomes more complex
Solution Approach 1:
The hollow space of the second panel serves multiple functions: it receives the first panel during retraction for compact storage, and it houses the Qwerty keypad for typing functionality, allowing a single structural element to provide both compactness and enhanced functionality

AI summary
A mobile electronic device including two planar panels that are typically suspended from one another and can assume a retracted position in which they substantially overlap one another and assume an extended position in which the panels do not completely overlap one another. In the extended position an additional portion of the elements of the user interface is exposed.
