Sliding Display Pivot for Keyboard Ergonomics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable devices fail to seamlessly transition between smartphone and keyboard modes due to issues with balance, keyboard layout disruption, and ergonomic design, particularly with touchscreen displays, leading to instability and cramped keyspaces.
Innovation Solution
A portable electronic device featuring a sliding carriage system that allows the touchscreen display to slide back and pivot over a base section with an integral keyboard, maintaining a slim profile while ensuring stability and ergonomic alignment of the display and keyboard, utilizing magnets and rollers for smooth operation and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display is tilted towards the user for ergonomic viewing, then viewing comfort is improved, but the device becomes unstable and may flip over backwards
Solution Approach 1:
A counterweight mechanism is introduced to balance the tilted display section. The counterweight compensates for the moment created by the tilted display, preventing the device from flipping over while maintaining the ergonomic viewing angle. This allows the display to be tilted for comfort without compromising overall device stability.
2Length of stationary object
If the touchscreen display is positioned on top of the keyboard surface, then the device maintains a slim profile, but the top row of keys loses space and creates an ergonomic step up
Solution Approach 1:
The display is positioned in a different spatial dimension relative to the keyboard. Instead of placing the display directly on top of the keyboard surface (occupying the same vertical space), the display is tilted at an angle and supported by the counterweight mechanism, creating a three-dimensional arrangement. This allows the display to be elevated without pressing down on the keyboard keys, maintaining both a slim overall profile and full keyboard key travel.
3Adaptability or versatility
If the device is designed to transform between smartphone and keyboard modes, then versatility is improved, but the transition mechanism increases device complexity and thickness
Solution Approach 1:
The device employs a dynamic transformation mechanism that allows smooth transition between smartphone and keyboard modes. The display section can be tilted and locked at different angles, and the counterweight mechanism dynamically adjusts to maintain balance throughout the transformation. This dynamic design enables versatile usage modes while keeping the mechanism relatively simple and the device thickness minimal.

AI summary
A portable, electronic device configured to transform between a smartphone usage mode and a keyboard-based usage mode. The device includes (i) a base section and (ii) a top section that includes a touchscreen display that sits over the base section when the device is in the smartphone mode. A sliding carriage system enables the top section to both (i) slide back over the base section, moving parallel to a top surface of the base section, and then fully expose the keyboard, and (ii) then pivot so that the display is at a conventional reading angle to the keyboard.
