Solution Overview
Problem
Conventional display apparatuses with tilt mechanisms using drawstrings face issues of instability due to limited support force, leading to shaking during touch input and potential damage, and have complex reciprocal mechanisms with restricted weight capacity.
Innovation Solution
A support device comprising a support bracket, pivot unit, and constant or torsion springs that allow adjustable tilt angles within a predetermined range, with a limiting unit to fix the maximum rotation angle, enhancing stability and reducing assembly complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a support bracket with drawstrings is used to support the display apparatus, then the display apparatus can be tilted at a small angle, but the support force is limited and the display apparatus shakes during touch input
Solution Approach 1:
The patent changes the elastic recovery mechanism from drawstrings to a spring mechanism, fundamentally altering the physical parameter of force generation. The spring provides continuous elastic force that scales with displacement, enabling stable support for heavier display apparatus and preventing shaking during touch input operations.
Solution Approach 2:
The support bracket is divided into multiple functional components: a fixed support portion, a rotatable support portion, and a spring mechanism. This segmentation allows each component to perform its specific function optimally - the spring provides force, the pivot provides rotation, and the bracket provides structural support, collectively resolving the stability issue.
2Ease of manufacture
If drawstrings are used as the elastic recovery mechanism, then the support bracket can be assembled, but the assembly process is complex and the weight capacity is limited
Solution Approach 1:
The patent extracts the elastic recovery function from the drawstring mechanism and isolates it into a dedicated spring component. This extraction simplifies the overall assembly process while simultaneously increasing the weight capacity, as the spring can be independently selected and installed without complex reciprocal mechanisms.
3Ease of operation
If the display apparatus is tilted at a small angle on a desktop, then it can display information, but touch input causes shaking and potential damage
Solution Approach 1:
The spring mechanism acts as a cushioning element that absorbs and dampens the forces generated during touch input. By providing elastic compliance, the spring prevents rigid transmission of shock forces to the display apparatus, thereby preventing shaking and potential damage while maintaining operational ease.
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 solution provides a stable and adjustable display apparatus that can support a wider range of weights, simplifies the reciprocal mechanism, and reduces assembly costs, ensuring secure and comfortable operation across various usage conditions.
Implementation Method 1
the constant force spring has a spring body coupled with the pivot unit. When the supporting angle changes in a predetermined range, an end portion of the spring body is movably connected to the support bracket
Implementation Method 2
The support device further includes a torsion spring. The support bracket further has a slot hole. The torsion spring is axially mounted on the pivot unit and close to the constant force spring
