Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural tractor operators face challenges in accurately positioning implements without repeatedly boarding and alighting from the vehicle, requiring multiple individuals for precise alignment, and there is a need for safer and more convenient external control mechanisms.
Innovation Solution
An agricultural work vehicle equipped with electronically controlled transmission, external switches for forward and reverse movement, and a mode switch to enable external manipulation, along with safety features like electronic brakes and sensitivity adjustments, allowing single-operator implement installation and precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the driver repeatedly boards and alights from the agricultural work vehicle to check positions, then the forward and rearward positions can be accurately determined, but the operation time and complexity increase significantly
Solution Approach 1:
The patent replaces the mechanical system of manual position checking (driver physically moving and visually assessing positions) with an electronic control system. The external switches electronically control the transmission to provide predetermined speed ratios, allowing the driver to set positions by simple switch operations rather than repeated boarding and alighting. This substitution of mechanical manual checking with electronic control resolves the contradiction by maintaining position accuracy while dramatically reducing the time required.
2Measurement precision
If two persons work together to position the implement, then the positioning accuracy improves, but the operational complexity and resource requirements increase
Solution Approach 1:
The patent enables the driver to perform positioning operations independently through external switches that provide predetermined speed ratios. The system allows single-operator implementation by making the vehicle self-sufficient for positioning tasks that previously required two people. The driver can control the transmission electronically to achieve accurate relative positioning without assistance, thereby reducing operational complexity and resource requirements while maintaining positioning accuracy.
3Ease of operation
If external switches are provided for forward and reverse movement, then the ease of operation for single driver improves, but the risk of erroneous operation increases
Solution Approach 1:
The patent implements a dynamic control system where the external switches are integrated with the transmission control. The transmission automatically adjusts speed ratios based on switch positions, providing dynamic adaptation to operational needs. This dynamic system allows easy external control while maintaining safety through automated transmission response that prevents erratic vehicle behavior, resolving the contradiction between operational ease and safety reliability.
