Adjustable Holding Device for Displays with Rotating Sliding Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional holding devices for LCDs are limited to specific sizes due to fixed holding members, making them unsuitable for displays of varying dimensions.
Innovation Solution
A holding device with rotatable and sliding lower holding arm units that adjust between extended and contracted positions, combined with an upper holding arm unit, to create a versatile holding space adaptable for different display sizes, and includes stop members and a cushion unit for stability and thickness adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If holding members are fixed relative to the base, then the structure is simple and stable, but the device can only accommodate displays of a particular size
Solution Approach 1:
The holding arms are designed to be movable rather than fixed, allowing them to adjust their positions to accommodate displays of different sizes. The lower holding arms can rotate about an axis between upper and lower positions, and can slide between extended and contracted positions, transforming the static structure into a dynamic one that adapts to various display dimensions.
Solution Approach 2:
The holding device is divided into multiple independent holding arm units (upper holding arm unit and pair of lower holding arm units) that can move relative to each other and to the base. This segmentation allows each arm to be independently positioned to fit different display sizes, resolving the contradiction between adaptability and structural simplicity.
2Adaptability or versatility
If holding arms are made movable to adjust for different display sizes, then adaptability improves, but the structure becomes more complex
Solution Approach 1:
The holding arms incorporate rotational and sliding movements to achieve adjustability. The lower holding arms rotate about an axis and slide along the base, providing dynamic positioning capability that allows the device to accommodate various display sizes without requiring an overly complex mechanism.
Solution Approach 2:
The holding arms can change their positional parameters (rotation angle, sliding distance) to adapt to different display dimensions. By varying these parameters, the device achieves versatility in accommodating different display sizes while maintaining a relatively simple mechanical structure.
3Adaptability or versatility
If the lower holding arm moves from extended to contracted position, then the holding space adapts to smaller displays, but the arm must traverse a longer path
Solution Approach 1:
The lower holding arm combines rotational movement about an axis with sliding movement along the base, creating a compound motion mechanism. This dynamic system allows the arm to efficiently transition between extended and contracted positions, reducing the adjustment time required to adapt the holding space to different display sizes.
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
Enables the secure retention of displays of varying sizes by adjusting the holding space dimensions and stability, accommodating displays of different thicknesses through the adjustable mechanism.
Implementation Method 1
a lower holding arm that is connected to the base and that is rotatable about an axis relative to the base between upper and lower positions
Implementation Method 2
the lower holding arm being movable relative to the base in a sliding direction transverse to the axis between an extended position to be distal from a center of the base and a contracted position to be proximate to the center of the base

AI summary
A holding device includes a base, an upper holding arm unit connected to an upper portion of the base, and a pair of lower holding arm units connected to the base. Each of the lower holding arm units includes a lower holding arm that is connected to the base and that is rotatable between upper and lower positions. Each lower holding arm is movable relative to the base in a sliding direction between an extended position and a contracted position. Each of the lower holding arm units further includes a stop member that extends into the base and that is operable for positioning the lower holding arm relative to the base. The lower holding arm units cooperate with the upper holding arm unit to define a holding space for retaining a display.
