Tractor Remote Control Module With Local Function Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control devices for agricultural tractors are limited in flexibility and user-friendliness due to fixed or cumbersome configuration of control elements, requiring access to a driver's cab interface for function assignment.
Innovation Solution
A remote control device with an integrated selection unit in an operating module allows flexible and convenient assignment of tractor or implement functions to control elements, enabling operation of hydraulic units and other tractor functions without needing cab access, featuring robust push buttons and LED feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If control elements are assigned to specific control valve blocks via a user interface in the driver's cab, then the remote control device can operate hydraulic units, but the configuration becomes cumbersome and requires access to the cab
Solution Approach 1:
The selection unit is extracted from the driver's cab interface and relocated to the remote control device itself. This allows the operator to select and assign functions directly at the remote control location, eliminating the need to access the cab for configuration changes while maintaining full adaptability of function assignment.
Solution Approach 2:
The selection unit acts as an intermediary between the operator and the control valve blocks. It provides a local interface that mediates the function selection process, allowing the operator to configure the remote control device without needing to access the main cab interface, thus simplifying the operation while preserving versatility.
2Adaptability or versatility
If the remote control device has fixed function assignment, then the structure is simple, but the flexibility of function assignment is limited
Solution Approach 1:
The selection unit provides multi-functionality by enabling the same control elements to be assigned to different control valve blocks and functions. This universal assignment capability allows a single remote control device structure to serve multiple operational needs without requiring multiple dedicated controls, thus achieving versatility without proportionally increasing complexity.
Solution Approach 2:
The function assignment is made dynamic through the selection unit, which allows the operator to change the mapping between control elements and functions as needed. This dynamic reconfigurability enables the device to adapt to different operational requirements while maintaining a relatively simple underlying hardware structure.
