Retractable Support Structure for Computing Device Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touchscreen laptops often topple backwards when users interact directly with the display surface due to the weight imbalance between the display and base members, negatively impacting the user experience.
Innovation Solution
A retractable support structure within the base member, pivotally connected via a shaft, extends to provide additional stability when the device is in open position, preventing toppling by increasing the force required to tip the device backwards, and includes non-skid elements for frictional support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the display member is made heavier to improve display quality, then the device becomes more stable when closed, but it topples backwards more easily when open
Solution Approach 1:
The patent applies a retractable support structure that dynamically adjusts based on the device state. The support extends automatically when the device is opened and retracts when closed, changing the stability characteristics in real-time to match the operational state, thereby preventing toppling during use while maintaining compactness when stored.
Solution Approach 2:
The retractable support acts as an intermediary element between the display member and base member. This intermediate structure provides additional stability when needed during touchscreen interaction, mediating the weight imbalance between the display and base without requiring permanent structural modifications.
2Stability of the object's composition
If a retractable support structure is added to prevent toppling, then device stability when open is improved, but device complexity increases
Solution Approach 1:
The retractable support structure is integrated within the existing base member housing, merging the support function into the existing device architecture. The support structure shares space with other internal components, and the lever mechanism utilizes the existing hinge assembly movement, thereby minimizing additional complexity while achieving the stability improvement.
Solution Approach 2:
The support structure is designed to be self-actuating through a lever mechanism that automatically extends and retracts based on the device opening and closing motion. This self-service mechanism eliminates the need for motors, sensors, or complex control systems, reducing overall device complexity while maintaining the stability function.
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 structure enhances user experience by significantly reducing the likelihood of the device toppling backwards, allowing for safer and more reliable interaction with the touchscreen, even when the display member is heavier or lighter than the base member.
Implementation Method 1
a spring fitted over the shaft and disposed within the structure, the spring biasing the extension towards the retracted state
Implementation Method 2
The structure may include non-skid elements for frictional support

AI summary
Examples disclosed herein provide a retractable structure for a computing device. The computing device can include a base member and a hinge assembly to couple a display member to the base member. The structure can be disposed within the base member such that the structure can be retractable within a rear sidewall of the base member and extendable from the rear sidewall when the hinge assembly is in an open position with respect to the base member.
