Portable Electronic Device Automatic Support Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tablet computers experience instability and a higher likelihood of shaking or falling when used with a keyboard attachment, leading to operational inconvenience and reduced user willingness to purchase and operate the device.
Innovation Solution
A portable electronic device design featuring an upper member with a display, a lower member with a keyboard and guiding grooves, supported by pivot portions and connecting members that allow the device to be automatically unfolded, forming an included angle and preventing backward inclination or falling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the tablet computer stands on the keyboard device, then the user can use both the keyboard device and the touch-controlled display, but the tablet computer may shake or fall backwardly while the user is touching or pressing the display
Solution Approach 1:
The patent implements a dynamic support structure where the support arm can automatically adjust its angle and position to maintain stability. The support arm transitions from a static attachment to an actively adjustable mechanism that responds to the tablet's position and user interaction forces, resolving the contradiction between adaptability and stability.
Solution Approach 2:
The device is divided into separate functional modules: the keyboard base, the adjustable support arm, and the tablet holder. This segmentation allows each component to be optimized independently - the keyboard provides a stable base while the support arm provides adjustable stabilization, resolving the stability issue without compromising usability.
2Stability of the object's composition
If a support structure is added to prevent shaking, then stability is improved, but the device complexity increases
Solution Approach 1:
The support arm incorporates automatic adjustment capabilities that respond to the tablet's weight and position without requiring manual intervention. The structure self-regulates to maintain optimal stability, providing the necessary support function without adding complex control systems or multiple adjustment mechanisms.
Solution Approach 2:
The support arm's geometric parameters (angle, length, position) are dynamically adjusted based on the tablet's position and user interaction. By changing these parameters rather than adding structural complexity, the system achieves stability through optimized geometry rather than additional components.

AI summary
A portable electronic device comprises an upper member, a lower member having two guiding grooves, two supports and two connecting members. One end of each support is pivoted to the upper member with a first pivot portion. The other end of each support is pivoted to the lower member with a second pivot portion. One end of each connecting member is pivoted at one side of the upper member, and the other end thereof is restricted in the guiding groove and capable of reciprocally sliding in the guiding groove.
