Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems for work vehicles, such as agricultural tractors and construction vehicles, are not compatible with all types of output elements like hydraulic circuits, and require specialized knowledge for installation, making them time-consuming and costly.
Innovation Solution
A control apparatus with control actuators, a signal receiver, and a control circuit module that mechanically engages manually operable control elements, allowing remote operation of vehicles with features like PTO shafts, hydraulic circuits, and steering wheels, using a wireless signal receiver and indicator lights for status visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wired remote control system is used to control output elements, then the control function can be achieved, but the installation requires specialized knowledge and becomes time-consuming and costly
Solution Approach 1:
The patent replaces wired mechanical/electrical connections with wireless communication technology. The remote control system uses radio frequency signals to transmit control commands without physical wiring, eliminating the need for specialized installation knowledge and reducing installation time and cost while maintaining remote control functionality
Solution Approach 2:
The patent introduces a wireless signal as an intermediary between the operator and the work vehicle's control elements. Instead of direct wired connections, control commands are transmitted through wireless signals that are received and processed by the vehicle's control system, simplifying the overall system architecture
2Ease of operation
If the operator stays in the cab to operate the vehicle, then control is maintained, but the operator cannot externally monitor implement operation
Solution Approach 1:
The patent uses wireless communication as an intermediary to transmit both control commands and status information between the operator and the work vehicle. This allows the operator to send control signals remotely while simultaneously receiving real-time feedback about vehicle and implement operation, eliminating the need to be physically present in the cab
3Adaptability or versatility
If existing remote control systems are used, then some output elements can be controlled, but compatibility with all types of output elements like hydraulic circuits is not achieved
Solution Approach 1:
The patent creates a universal remote control system that can interface with multiple types of output elements including electrical controls, hydraulic circuits, and mechanical operators. The system uses wireless communication and adaptable control mechanisms that can work with different vehicle types and control element configurations, achieving broad compatibility across various work vehicles and implements
Data Source
AI summary
A system and method of controlling manually operable control elements of a vehicle using a control apparatus mounted in the vehicle. The control apparatus is mechanically engaged with at least one of the manually operable control elements of the vehicle. A control circuit module receives commands signals from a control source. The control circuit module generates command signals to cause actuation of at least one control actuator to manipulate the control apparatus in response to the command signals, which, in turn, manipulates the manually operable control element of the vehicle.
