Supporting Frame With Cam-Driven Elastic Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing supporting frames with four-bar linkages have complex structures and large sizes due to the need for a sliding slot for the elastic body, making assembly difficult.
Innovation Solution
A supporting frame design featuring a base with a mandrel, elastic body, first and second cams, and an arm that allows the display to be adjusted to any height using a four-bar linkage mechanism, with cams interacting to deform the elastic body and provide support, and an adjustable screw nut for preload adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sliding slot is added to accommodate the elastic body, then the support function is improved, but the structure becomes complex and size increases
Solution Approach 1:
The patent extracts the elastic body from the rod structure by removing the need for a sliding slot. The elastic body is positioned independently between the first and second fixing elements, separating its function from the rod's structural role. This eliminates the complex sliding slot mechanism while maintaining the support function through the four-bar linkage's natural motion.
2Reliability
If a sliding slot is added to accommodate the elastic body, then the support function is improved, but assembly becomes difficult
Solution Approach 1:
The patent segments the support mechanism into distinct functional components: the four-bar linkage (first rod, second rod, first fixing element, second fixing element) and the elastic body. This segmentation allows each component to be manufactured and assembled independently, eliminating the need for complex integrated sliding slots and simplifying the overall assembly process.
3Area of stationary object
If the arm length is increased to extend the display area, then the display area is improved, but the weight increases
Solution Approach 1:
The patent employs a dynamic four-bar linkage mechanism that allows the arm to rotate and adjust its position. This dynamic structure enables the display area to be extended through rotational movement rather than requiring a permanently longer arm, thereby maintaining a compact, lightweight structure while providing extended display capability when needed.
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 design simplifies the structure and assembly process, enabling a compact and versatile supporting frame that can bear displays of varying weights and maintain them at any height, while providing consistent support during movement.
Implementation Method 1
an elastic body sets on the mandrel, abutting against the first fixing element, and constantly providing an elastic force
Implementation Method 2
a first cam slidably sets on the mandrel and abutting against the elastic body; a second cam sets on the mandrel and abutting against the first cam and the second fixing element
Implementation Method 3
the proximal connector, the remote connector, the first rod, and the second rod are together configured to a four-bar linkage

AI summary
A supporting frame is provided, which includes a base, a mandrel, an elastic body, a first cam, a second cam, an arm, and a first pivoting element. When the arm pivotally rotates with respect to the base, the mandrel rotates along with the arm and one of the first cam and the second cam is driven to rotate, the first cam and the second cam then push against each other so that the first cam moves along the first direction and deforms the elastic body, thereby, the display can stop at any height between the highest position and the lowest position.
