Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional driving simulators are used to provide realistic training environments, then training realism is improved, but device complexity and cost increase significantly
Solution Approach 1:
The patent uses a virtual copy of the agricultural working machine's control interface displayed on a standard monitor, replicating the machine's electronic on-board information system, machine optimization system, and automatic driver interface without requiring physical duplication of complex simulator hardware. This allows realistic training through software-based visualization on conventional display devices.
2Adaptability or versatility
If traditional driving simulators are deployed to enable operator training, then training capability is improved, but flexibility and accessibility deteriorate due to fixed location requirements
Solution Approach 1:
The system enables the agricultural working machine's control interface to function both as the actual machine control system and as a training simulator interface. The same electronic on-board information system, machine optimization system, and automatic driver interface serve dual purposes: operational control during actual work and training simulation when accessed through the display unit, eliminating the need for separate dedicated simulator hardware and enabling flexible training from any location with standard computing equipment.
3Measurement precision
If detailed process models and multiple parameters are simulated to achieve realistic crop processing simulation, then simulation accuracy is improved, but computing requirements and system complexity increase
Solution Approach 1:
The system uses the agricultural working machine's own electronic control systems and existing sensors to generate simulation data, eliminating the need for separate complex simulation hardware. The machine's electronic on-board information system, machine optimization system, and automatic driver provide the computational infrastructure for accurate process modeling of crop processing parameters, reducing external computing requirements while maintaining high simulation fidelity.
