Monitor Carrier Transmission for Low-Force Pivoting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitor carriers require high operation forces to pivot monitors due to the elevation change of the center of gravity, and current solutions either increase manufacturing costs or complexity with springs or decoupling mechanisms, or are limited by the size of the monitor due to protruding extension arms.
Innovation Solution
A device using a non-uniformly translating transmission to pivotably connect the monitor's connection element to the support frame, allowing for simple and cost-efficient design with reduced operation forces by maintaining the monitor's center of gravity elevation during pivoting, eliminating the need for protruding extension arms and complex configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a rotary joint with fixed axis of rotation is used to pivot the monitor, then the configuration is simple and manufacturing costs are low, but high operation forces are required due to elevation change of the center of gravity
Solution Approach 1:
The patent applies the equipotentiality principle by designing a transmission mechanism that keeps the center of gravity of the monitor at a constant elevation during pivoting. The non-uniformly translating transmission converts the rotational movement into a path that maintains the center of gravity at a fixed height, eliminating the need to overcome gravitational force changes and thus reducing operation forces while keeping the configuration relatively simple
2Force
If a spring is added to assist pivoting against gravity, then operation forces are reduced, but manufacturing costs increase and the device becomes more complex
Solution Approach 1:
The patent replaces the spring-based mechanical assistance system with a transmission mechanism that inherently maintains the center of gravity at constant elevation. This substitution eliminates the need for springs and their associated alignment adjustments, reducing both device complexity and manufacturing costs while achieving the same effect of reducing operation forces
3Force
If a laterally protruding extension arm is used to position the rotary joint, then operation forces are reduced, but the device becomes heavier and more expensive
Solution Approach 1:
The patent uses the equipotentiality principle through a non-uniformly translating transmission that keeps the center of gravity at constant elevation during pivoting. This eliminates the need for laterally protruding extension arms, thereby reducing the weight of the monitor carrier while maintaining low operation forces
4Force
If a laterally protruding extension arm is used to position the rotary joint, then operation forces are reduced, but the size of the monitor is limited by the length of the extension arm
Solution Approach 1:
The patent applies equipotentiality through a transmission mechanism that maintains constant center of gravity elevation. This approach does not require laterally protruding extension arms with fixed length constraints, allowing the monitor carrier to accommodate monitors of various sizes without being limited by extension arm length, thus improving adaptability
