Tracked Vehicle Single-Stick Control for One-Handed Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional civilian tracked vehicles require multi-handed operation, leading to coordination challenges and increased risk of operating errors due to the separation of steering, direction control, and work function controls, which can result in accidents, especially when the driver is distracted or tired.
Innovation Solution
Integration of the direction control device and work function control unit into a single, manually operated control stick, allowing for one-handed operation of steering, direction, and work functions, including tilting and rotating, which minimizes coordination challenges and reduces the risk of errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the directional control device and control unit are separated into different control elements, then each control function can be independently operated, but the driver must use multiple hands to operate steering, direction, and working functions, leading to coordination challenges and increased risk of operating errors
Solution Approach 1:
The patent combines the directional control device and the control unit for working functions into a single integrated operating device with one manually operable control stick. This merging allows the driver to operate steering, direction of travel, and working functions (such as tilting and rotating) using only one hand, eliminating the need for multi-handed operation and reducing coordination challenges while maintaining independent control of each function
2Reliability
If multiple control elements are used for different functions, then each function can be precisely controlled, but the coordination challenges increase and operating errors occur more frequently due to distraction or fatigue
Solution Approach 1:
By integrating multiple control functions into a single operating device with one control stick, the patent reduces the number of separate control elements the driver must manage. This integration maintains precise control capability for each function (steering, direction, working functions) while significantly reducing coordination difficulty and the risk of operating errors caused by distraction or fatigue
Solution Approach 2:
The single control stick is designed to perform multiple functions: controlling steering, direction of travel, and working functions (tilting and rotating). This multi-functional design allows one control element to replace multiple separate controls, improving reliability by reducing the complexity of coordination while maintaining full operational capability
