Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional support stands for tablet computers are large, cumbersome, and difficult to store or transport due to their size, which is not suitable for the increasing portability and convenience of tablet devices.
Innovation Solution
A foldable three-section clamping device with rotatable pivot members, adjustable extension members, and a latch structure that allows for full angle adjustment and compact folding, enabling it to securely hold both small-sized mobile phones and large-sized tablet computers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional support stand is designed to match the size of tablet computers, then it can securely hold the device, but it requires a relatively large structural size which takes up space and is difficult to store and transport
Solution Approach 1:
The support stand is divided into three collapsible support arms that can be folded together. Each support arm can be independently adjusted and folded, allowing the structure to be compacted into a small volume for portability while maintaining full extension capability for supporting tablets when deployed
Solution Approach 2:
The support stand incorporates rotatable pivot members and adjustable extension members that allow dynamic reconfiguration of the structure. The support arms can rotate at pivot points and extend or retract to adapt to different tablet sizes and viewing angles, providing reliability across multiple configurations while enabling compact folding for storage
2Area of stationary object
If a support stand is designed with large structural size to support tablet computers, then it provides adequate support area, but it becomes cumbersome and difficult to port around
Solution Approach 1:
The three support arms are designed to nest within each other when folded, with each arm containing or overlapping the previous one. This nesting arrangement minimizes the overall volume when the stand is collapsed, making it easy to carry in a bag or pocket, while allowing full deployment of the support area when needed
3Reliability
If a clamping device is designed with fixed structure to provide stable clamping, then it maintains consistent clamping force, but it cannot adapt to different sizes of portable electronic products
Solution Approach 1:
The clamping device features adjustable extension members with sliding mechanisms that allow the clamping arms to be repositioned along the support structure. This dynamic adjustment capability enables the device to accommodate different product sizes while maintaining stable clamping force through controlled positioning and locking mechanisms
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 device provides a compact solution for storing and portability while offering a wide clamping range, facilitating convenient use and storage by allowing nearly 360-degree angle adjustment and secure clamping of various-sized portable electronic products.
Implementation Method 1
a tension spring is provided in the first support unit to contact the movable piece to maintain the clamping force between the clip and the movable piece
Implementation Method 2
the second clamping arm is provided with at least a first spring in contact with the extension member, in the absence of external force, the first spring enables the second clamping arm to move to its original position
Implementation Method 3
a second support unit, provided with a rotatable second pivot member
