Pivotal Support Structure for Ergonomic Tablet Angle Holding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users experience hand fatigue and discomfort when using larger and heavier tablet computers, especially when trying to watch videos, as existing support methods are not ergonomic or convenient.
Innovation Solution
A pivotal device with a base and flip module that includes movable members with pivotal and sliding portions, utilizing frictional resistance and an elastic member to adjust the angle of the support, allowing for comfortable positioning of electronic devices between 35° and 165° relative to the base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the screen size and weight of tablet computers are increased to meet the need of watching films, then the viewing experience is improved, but hand fatigue increases and even causes pain
Solution Approach 1:
The patent creates a support structure that replicates the function of human hand holding, providing mechanical support to bear the weight of the tablet. The support module with pivotal and sliding portions simulates the natural holding posture, transferring the load from hands to the support structure, thereby eliminating hand fatigue while maintaining large screen benefits
2Ease of operation
If a support structure is added to reduce hand fatigue, then hand comfort is improved, but the device complexity increases
Solution Approach 1:
The patent implements a nested structure where the third movable member is received within the second movable member, and both are received within the base. The movable members are nested concentrically, with each member containing the next smaller member. This nesting approach consolidates multiple adjustment functions into a compact integrated structure, reducing overall complexity while maintaining full functionality
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
Provides a comfortable and ergonomic support system that reduces hand fatigue by allowing adjustable angles for electronic devices, enhancing user experience during extended use.
Implementation Method 1
an elastic member extending through the first movable member and biassing the first movable member towards the retracted position
Implementation Method 2
When the third movable member pivots relative to the second movable member, frictional resistance is generated to fix an angle between the third movable member and the second movable member

AI summary
A pivotal device for a support of an electronic device includes a base and a flip module. The flip module includes first, second movable member, and third movable members. The second movable member is pivotably connected to the first movable member and is slideably mounted to the base. The third movable member is pivotably connected to the base and the second movable member and is slideably mounted to the first movable member. When the third movable member pivots relative to the second movable member, frictional resistance is generated to fix an angle between the third movable member and the second movable member. Operation of the pivotal device during the extending or closing procedure is smooth.
