Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display supporting devices struggle to meet the torque requirements of large-sized displays due to the limited size of torsion springs, which restricts the thickness of the fixing component and limits the overall thickness of the device.
Innovation Solution
The display supporting device incorporates a dual torsion spring unit system with separate spindle rods and accommodating grooves, allowing for increased elastic force and flexibility in positioning, enabling the device to support larger displays while maintaining a thin profile.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the thickness of the fixing component is thinned to achieve a light and thin overall profile, then the overall thickness is reduced, but the torque capacity is limited and cannot meet the needs of large-sized displays
Solution Approach 1:
The patent positions the torsion springs in accommodating grooves that are offset from the rotation axis, utilizing the radial dimension rather than concentrating mass at the center. This dimensional redistribution allows the springs to be larger without increasing the overall thickness of the fixing component, thereby resolving the contradiction between thin profile and torque capacity.
Solution Approach 2:
The fixing component is segmented into functional zones: the rotation axis area for minimal thickness and the radial accommodating grooves for torque-generating springs. This segmentation allows different parts to serve different purposes - the center remains thin while the periphery provides torque capacity through properly positioned springs.
2Force
If the size of the torsion springs is increased to provide sufficient torque for large-sized displays, then the torque capacity is improved, but the thickness of the fixing component must be increased
Solution Approach 1:
Instead of increasing spring size by increasing thickness (axial dimension), the patent increases spring size by utilizing the radial dimension through offset positioning in accommodating grooves. This allows larger springs to fit within the same thickness constraint, resolving the contradiction between torque capacity and thin profile.
3Force
If a single large torsion spring is used to provide sufficient torque, then the torque capacity is improved, but the device complexity and space requirements increase
Solution Approach 1:
The patent uses multiple smaller torsion springs distributed in separate accommodating grooves around the rotation axis, replacing what would be a single large spring. This segmentation reduces the complexity of each individual spring, allows for easier manufacturing and assembly, and distributes the torque-generating function across multiple simpler components.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design effectively enhances the torque capacity to support large-sized displays by distributing the torsion springs away from the axis of rotation, reducing the overall thickness and allowing for adjustable positioning of the display.
Implementation Method 1
a first torsion spring unit constantly providing a first elastic force and having a first spindle rod and at least one first torsion spring, wherein the first spindle rod extends along a first axis being substantially parallel to the main axis, and wherein the at least one first torsion spring is sleeved on the first spindle rod and abuts against the bearing base and the quick-release base respectively

AI summary
A display supporting device is provided and includes: a protruding neck; a quick-release unit having a quick-release base and a fixing member, where the quick-release base is detachably disposed on the protruding neck by the fixing member; a carrying unit having a bearing base, where the bearing base is connected to the quick-release base, and is able to rotate between a first position and a second position relative to the quick-release base with a main axis; and a first torsion spring unit constantly providing a first elastic force and disposed along a first axis that is substantially parallel to the main axis. The display supporting device can effectively reduce the overall thickness of the carrying unit and meet the torsion requirement of a large-sized display by deviating an arrangement position of the first torsion spring unit from the main axis.
