Rotatable Tablet Stand Frame With Stable Angle Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior art stand frames for tablet devices are prone to loosening and vibration, leading to reduced lifetime, and the hand strap is fixed and prone to wear, making them difficult to use effectively for long periods.
Innovation Solution
A multifunctional rotatable stand frame with a buckling ring and circular wall that securely retains the disk at specific angles, allowing stable support and adjustable positioning, and a hand strap design that is adjustable and replaceable to prevent wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the disk is buckled to the annular recess by using the buckle to allow continuous rotation, then the disk can rotate to various positions, but the frame body becomes loose and difficult to fix on a specific position, causing vibration and reduced lifetime
Solution Approach 1:
The patent applies dynamics by making the retention mechanism adjustable between two states: a first state where the buckling ring retains the disk at a specific position (for stability), and a second state where the disk can rotate freely (for continuous positioning). This dynamic switching resolves the contradiction between stability and ease of operation.
Solution Approach 2:
The patent changes the retention parameter by moving the buckling ring between different positions relative to the disk. When the buckling ring is in the first position, it engages with the disk to provide stable retention. When moved to the second position, it releases the disk for free rotation. This parameter change resolves the contradiction between fixed stability and rotational freedom.
2Ease of operation
If the hand strap is fixed to two ends of the disk, then it provides hand holding function, but it is unreplaceable and prone to wear and dirt over time
Solution Approach 1:
The patent segments the hand strap system into a removable strap component and a mounting structure on the disk. This allows the hand strap to be separated from the disk, enabling replacement when worn or dirty, while maintaining the hand holding function. The segmentation resolves the contradiction between providing a functional hand strap and making it replaceable.
3Ease of manufacture
If a simple buckling ring and circular wall structure is used, then the overall cost is reduced, but the disk must be securely retained at specific angles for stable support
Solution Approach 1:
The patent employs self-service through the buckling ring's automatic engagement mechanism. The buckling ring features buckles that automatically engage with trenches in the circular wall when the disk is rotated to specific angles, providing stable retention without requiring additional complex locking mechanisms or increasing manufacturing cost. This self-service feature resolves the contradiction between simplicity and reliability.
