Handheld Device Sliding Keyboard Pivot Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld electronic devices with sliding designs often suffer from a lack of integrity in appearance due to height differences between the display screen and keyboard, making touch control operations inconvenient.
Innovation Solution
A handheld electronic device design featuring a first body, a pivot member, a second body, and a third body, where the pivot member is pivoted to the first body, and the second and third bodies are stacked and pivotally rotated to form a continuous surface when the second body slides, allowing for an integral appearance and improved input interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display screen is slid relative to the keyboard to expose the keyboard, then the user can perform input operations, but a height difference is formed between the screen and keyboard resulting in a lack of appearance integrity
Solution Approach 1:
The patent applies the dynamics principle by making the keyboard body pivotally rotatable relative to the display screen body. This allows the keyboard to dynamically adjust its position and angle, transitioning from a flat stacked state to a tilted expanded state. The pivotal rotation mechanism enables the keyboard surface to form a continuous plane with the display screen, eliminating height differences while maintaining operational accessibility.
2Volume of moving object
If the display screen and keyboard are stacked to reduce device size, then portability is improved, but the manual process for body motion becomes complex
Solution Approach 1:
The patent merges the stacking function with the pivoting function into a single integrated mechanism. The keyboard body is both slidable and pivotally rotatable relative to the display screen body, combining two degrees of freedom into one unified structure. This allows the device to transition smoothly between compact and expanded states without requiring separate manual operations for each movement type, thereby simplifying the overall manual process.
3Adaptability or versatility
If the keyboard is exposed by sliding the display screen, then input functionality is enabled, but multiple manual steps are required for body motion
Solution Approach 1:
The patent implements preliminary action by pre-configuring the keyboard body with both sliding and pivotal rotation capabilities. The pivot member is预先 installed to enable automatic rotation when the keyboard is slid out. This preliminary structural arrangement ensures that when the user slides the display screen to expose the keyboard, the pivotal rotation occurs automatically as part of the same motion, eliminating the need for separate manual steps and reducing the time required for body motion.

Function Achieved in This Case
The design provides a comfortable input interface by forming a continuous surface, increasing input speed and simplifying the manual process of transitioning from a stacked to an expanded state, enhancing user convenience.
Implementation Method 1
the pivot member is pivotally rotated relative to the first body automatically to drive the second body to tilt
Implementation Method 2
When the second body slides along the pivot member to expose the third body

AI summary
A handheld electronic device includes a first body, a pivot member, a second body and a third body. The pivot member is pivoted to the first body. The second body is slidably disposed on the pivot member. The third body is pivoted to the first body and stacked between the first body and the second body, such that the handheld electronic device is in a stacked state. When the second body slides along the pivot member to expose the third body, the pivot member is pivotally rotated relative to the first body automatically to drive the second body to tilt, the third body is pivotally rotated relative to the first body automatically to tilt, and a top surface of the second body and a top surface of the third body together form a continuous surface, such that the handheld electronic device is in an expanded state.
