Parallelogram Carrier Arm With Rotating Joint for Fixed Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carrier devices lack a mechanism to efficiently balance and rotate an object while maintaining a fixed orientation, limiting their versatility and ease of manipulation.
Innovation Solution
A carrier device incorporating a rotatable joint bracket with a hingeable connecting link, allowing for synchronized vertical movement and horizontal rotation, and utilizing a parallelogram linkage system with a connecting link that can hinge and rotate, enabling easy manipulation and balanced positioning of objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional carrier device with separate balancing mechanisms is used, then each link can be balanced independently, but the device complexity increases and requires multiple balancers
Solution Approach 1:
The patent combines two separate balancing mechanisms into a single integrated balancer system. The connecting link serves as a common element that transmits balancing forces between the first and third links, allowing one balancer to balance the entire articulated arm system rather than requiring separate balancers for each link.
Solution Approach 2:
The connecting link acts as an intermediary element between the first and third links. It transmits forces and movements between these links, enabling the balancer to control the position of the articulated arm through a single mechanism rather than requiring direct control of each link.
2Stability of the object's composition
If a fixed orientation mechanism is used, then the joint bracket maintains stable orientation, but the ability to rotate and reposition the object is limited
Solution Approach 1:
The patent employs dynamic joints that allow the articulated arm to rotate and change position while maintaining the fixed orientation property. The parallelogram linkage dynamically adjusts to keep the joint bracket oriented correctly regardless of the arm's position, enabling both stability and versatility.
Solution Approach 2:
The connecting link with rotational joint means provides multiple functions: it connects the first and third links, allows vertical movement synchronization, enables horizontal rotation, and maintains the fixed orientation of the joint bracket. This single component performs what would traditionally require multiple separate mechanisms.
3Reliability
If a parallelogram linkage system is used, then the joint bracket is held in fixed orientation, but the mechanism complexity increases
Solution Approach 1:
The patent merges the parallelogram linkage functionality into a compact configuration where the connecting link serves multiple purposes. Instead of separate mechanisms for orientation control and link connection, the connecting link with rotational joint means integrates these functions, reducing overall complexity while maintaining reliability.
