Operating Lever Line Layout for Balanced Torque Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control elements for machines, such as excavators, lack ergonomic design and efficient torque distribution, leading to operator fatigue and reduced precision in operation.
Innovation Solution
A control element with paired control lines arranged in helical bundles around a central axis, with connection points spaced apart to balance torques and forces, ensuring intuitive and precise operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If control lines are arranged in a single bundle, then the structure is simple, but torque distribution is unbalanced causing operator fatigue
Solution Approach 1:
The control line arrangement is segmented into multiple bundles (first line bundle and second line bundle) positioned at different locations relative to the central axis. This segmentation allows each bundle to carry specific control lines that balance the torque distribution, reducing operator fatigue while maintaining a manageable structural complexity through systematic organization.
2Ease of operation
If connection points are close together, then the structure is compact, but torque balancing is ineffective
Solution Approach 1:
The connection points are positioned asymmetrically at different distances from the central axis, with the first connection point at a first distance and the second connection point at a second distance. This asymmetric arrangement creates a torque balancing effect where the moments generated by control lines in different bundles counterbalance each other, improving operational ease while accepting a slightly increased volume for the control element.
