Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing articulation type supporters for portable electronic devices are limited in supporting distance and stability, especially when used in varying positions like beds or vehicles, due to weight-bearing issues and limited rotational motion.
Innovation Solution
An articulation type supporter with a base frame, movable frame, and multiple connection frames connected through hinge units, featuring a brake unit and displacement adjusting mechanism to allow stable upward and downward rotation, swivel motion, and folding, ensuring the device can be used comfortably over extended periods without sagging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the link members are arranged long to increase supporting distance, then the supporting distance is improved, but the end member becomes bulkier and heavier which limits weight-bearing capability
Solution Approach 1:
The link member is divided into multiple segments (first link member, second link member, third link member) connected by rotation units. This segmentation allows the structure to achieve long supporting distance through articulated folding while distributing the weight-bearing load across multiple connection points, preventing any single end member from becoming excessively bulky.
2Strength
If the link members are made shorter to reduce weight, then the weight-bearing capability is improved, but the supporting distance is limited
Solution Approach 1:
The link members are designed with rotation units that enable dynamic folding and extension. This allows the supporter to adapt its configuration - extending to long distances when needed while maintaining manageable segment lengths that can effectively bear weight, thus resolving the contradiction between length and strength.
3Stability of the object's composition
If a single rigid structure is used to maintain stability, then the stability is improved, but the adaptability to different positions and angles is reduced
Solution Approach 1:
The supporter employs multiple rotation units with brake mechanisms that enable dynamic adjustment to various angles and positions. The brake units provide stability at selected positions by preventing unintended movement, while the articulated structure maintains adaptability to accommodate different usage scenarios and device orientations.
Solution Approach 2:
The brake units in the rotation mechanisms provide feedback control by automatically engaging to maintain stability at adjusted positions. This allows the structure to adapt to different positions while maintaining stability through the feedback mechanism that prevents drift from the selected configuration.
4Adaptability or versatility
If multiple joints are added to increase adaptability, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The complex articulated structure is segmented into standardized modules (link members with integrated rotation units and brake mechanisms). This modular segmentation makes the complex multi-joint system easier to manufacture, assemble, and maintain, thus reducing the practical complexity despite the increased adaptability.
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 supporter provides stable and convenient use of portable devices by allowing free rotational motion and easy cable management, maintaining stability even when the device is positioned far from a fixed structure, enhancing user experience and usability.
Implementation Method 1
a first elastic member (36) installed by the second hinge pin (38) in such a way that one end is supported by the side wall or the bottom of the engaging groove (16), and the other end provides the elastic force for the first pole (30) and the first ratchet wheel (56) to be engaged with each other
Implementation Method 2
a first ratchet wheel (56) configured to prevent rotation at the central shaft (54) in a fifth through hole (50) corresponding to the slit (44) of the horizontal hinge shaft (42)
Implementation Method 3
a brake unit configured to limit a downward rotation of the movable frame (40) in response to a weight of a previously set item (G) applied from the other end of the movable frame (40), and allow an upward and downward rotation when a user's force is applied
