Distributor Boom Rotary Line Mounting for Large Folding Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing distribution boom devices lack flexibility and effective application in folding mechanisms, particularly for large angular ranges, due to limitations in the design of line sections and support systems.
Innovation Solution
A device for a distribution boom featuring a line section holder with a rotary bearing that allows the line section to rotate freely, supported by a mast segment, enabling a wide range of motion and increased mass capacity, with the line running through a circular path defined by the pivot bearing, allowing for unrestricted rotation and enhanced flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cable section holder supports the swivel cable section directly without a swivel bearing, then the device structure is simpler, but the rotating cable section cannot achieve unrestricted rotation and large angular ranges
Solution Approach 1:
A swivel bearing is introduced as an intermediary component between the cable section holder and the swivel cable section. This bearing enables unrestricted rotation and large angular ranges while maintaining a relatively simple overall device structure, resolving the contradiction between adaptability and complexity.
2Weight of moving object
If the mast cable section supports the swivel bearing directly, then the cable section holder structure is simpler, but the rotating cable section cannot have large mass (minimum 50 kg, preferably 100-200 kg)
Solution Approach 1:
The support function is segmented between the cable section holder (which provides structural support) and the swivel bearing (which provides rotational support). This segmentation allows the rotating cable section to have large mass (minimum 50 kg, preferably 100-200 kg) while keeping the overall device structure manageable.
3Adaptability or versatility
If the cable is routed outside the circle defined by the pivot bearing, then the cable routing is simpler, but the rotating retaining element cannot achieve relatively unrestricted rotation
Solution Approach 1:
The cable is routed through the circular path defined by the pivot bearing, utilizing the rotational dimension. This routing approach enables the rotating retaining element to achieve unrestricted rotation while keeping the cable routing relatively simple and organized within the defined circular geometry.
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 improved flexibility and effective application in folding mechanisms, enabling the distribution boom to handle large angular ranges and increased mass, making it suitable for applications like tremie systems and folding masts, while maintaining structural integrity and operational efficiency.
Implementation Method 1
The rotatable connection of the rotary line section with the mast line section and the rotatable connection of the rotary holding element with the mast segment by means of the rotary bearing enable the rotary holding element with the rotary line section to rotate vertically downwards in one direction, especially due to gravity.
