Asymmetric Tablet Recess for Gravity Center Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tablet PCs are difficult to hold with one hand due to their symmetrical flat casing and heavy battery pack, which increases rotating torque and leads to user fatigue and accidental drops, especially when used outdoors or traveling.
Innovation Solution
A tablet electronic device with a rotatable structure featuring a thicker second side and a recess to accommodate heavy components, shifting the gravity center and reducing rotating torque, allowing for easier one-handed operation and ergonomic comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the battery pack is disposed at the back of the tablet PC to keep the gravity center at the geometric center, then the structural balance is improved, but the rotating torque increases and one-handed holding becomes difficult
Solution Approach 1:
The patent applies asymmetry by disposing the battery pack at the rear side of the tablet PC rather than at the geometric center. This asymmetric arrangement shifts the gravity center toward the rear side, creating a counterbalancing effect that reduces the rotating torque when held one-handed, while still maintaining overall structural balance through careful positioning.
Solution Approach 2:
The patent changes the position parameter of the battery pack from the geometric center to the rear side of the device. This parameter change directly affects the gravity center location and the distribution of weight, thereby reducing the rotating torque and improving one-handed holding comfort while preserving structural stability.
2Ease of operation
If the weight of the tablet PC is reduced to relieve user fatigue, then the ease of operation is improved, but the battery capacity may be compromised
Solution Approach 1:
The patent optimizes the weight distribution parameters by positioning the battery pack at the rear side rather than uniformly distributing weight. This allows for reduced overall device weight while maintaining adequate battery capacity, as the strategic placement improves handling characteristics without sacrificing energy storage capacity.
3Area of moving object
If the screen size is increased to provide better display, then the functionality is improved, but the distance between gravity center and holding side increases, increasing rotating torque
Solution Approach 1:
The patent uses asymmetric battery pack placement at the rear side to counterbalance the increased weight and size of the display screen. This asymmetric arrangement creates a counterbalancing moment that offsets the increased rotating torque caused by the larger screen, maintaining one-handed holding comfort despite the enhanced display functionality.
