Swivel Working Machine Control for Intuitive Swivel-Swing Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators accustomed to using TLB machines face challenges in seamlessly transitioning to swivel working machines due to the need to switch between swivel and swing operations, which can be confusing and inefficient.
Innovation Solution
A swivel working machine with a controller that includes an operation pattern shifting unit to facilitate switching between swivel and swing movements by altering the operation member's function based on operator input, allowing for intuitive operation pattern selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the swivel working machine uses separate operation members for swivel and swing movements, then the machine can perform both functions, but the operator experiences confusion and reduced ease of operation when transitioning from TLB machines
Solution Approach 1:
The operation member is designed to perform multiple functions by selectively controlling either the swivel movement or the swing movement based on the operational mode. This allows a single operation member to replace what would traditionally require separate controls, making the machine adaptable to different operational needs while simplifying the interface for operators familiar with TLB machines
2Adaptability or versatility
If the machine provides multiple operation modes for different functions, then it can accommodate various operational needs, but the device complexity increases
Solution Approach 1:
The control system dynamically switches between different operational modes (swivel operation mode and swing operation mode) based on operator input or system state. This dynamic reconfiguration allows the machine to adapt its control characteristics in real-time without requiring permanently separate control systems for each function, thereby managing complexity while maintaining versatility

AI summary
A swivel working machine includes a machine body swivelable around a swivel axis, a working device attached to the machine body swingably around a swing axis, an operation member to be handled and operated by an operator, and a controller to control swivel movement, which is a swiveling movement of the machine body, and swing movement, which is a swinging movement of the working device. The controller includes an operation pattern shifting unit configured or programmed to perform shifting between a swivel operation state where operation of the operation member in a specific direction causes the swivel movement and a swing operation state where the operation of the operation member in the specific direction causes the swing movement.
