Two-Axis Joystick Control for Simultaneous Dumper Functions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing operating devices for commercial vehicles require operators to manually control multiple functions sequentially, leading to tedious and error-prone operations when simultaneous control is necessary, hindering efficiency and safety.
Innovation Solution
A demountable operating device with a two-axis joystick and selection elements allows for intuitive simultaneous control of two functions using one hand, featuring an endless chain of operating modes that can be dynamically adjusted based on usage patterns and safety parameters, enabling wireless communication with the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple operating elements are provided for controlling different functions, then each function can be controlled individually, but simultaneous control of multiple functions becomes tedious and error-prone requiring both hands
Solution Approach 1:
The patent combines multiple control functions into a single two-axis joystick. The first axis controls a first function while the second axis controls a second function, allowing simultaneous control with one hand. This merging of multiple operating elements into one unified control device resolves the contradiction by enabling simultaneous function control without requiring multiple separate operating elements.
Solution Approach 2:
The two-axis joystick serves multiple functions simultaneously - controlling both first and second functions through its two independent axes. This multi-functional design allows a single operating element to perform the work of multiple separate controls, improving ease of simultaneous operation while reducing the overall number of operating elements needed.
2Productivity
If sequential operation of functions is used, then operating elements can be simple, but time consumption increases and productivity decreases
Solution Approach 1:
By merging control of multiple functions into a single two-axis joystick, the system enables parallel execution of functions that were previously sequential. The operator can simultaneously adjust both axes to control multiple functions at once, dramatically reducing the time required to perform work processes that involve multiple functions.
3Reliability
If manual dual-hand operation is required for simultaneous function control, then each function can be controlled precisely, but operator fatigue increases and safety decreases
Solution Approach 1:
The patent merges control of multiple functions into a single joystick that can be operated with one hand, specifically mentioning that the two axes can be controlled with a thumb. This design improves operational safety by reducing operator fatigue associated with dual-hand operation while maintaining precise control capability through the intuitive two-axis interface.
