Solution Overview

Problem

Current electronic control systems for agricultural machines lack efficient methods for controlling auxiliary functions without the need for additional hardware devices like joysticks, limiting user flexibility and convenience in operating complex agricultural machinery.

Innovation Solution

The system employs a data bus network infrastructure with a user terminal and electronic control units, allowing for the display of virtual control elements on a terminal display, enabling users to map and control auxiliary functions through user input, eliminating the need for separate control devices by generating and transmitting control signals directly to the electronic control units via the data bus.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If additional hardware devices like joysticks are used for controlling auxiliary functions, then control capability is improved, but device complexity increases

Engineering Contradiction:
Improvecontrol capabilityVSAvoidhardware complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent creates virtual copies of control elements (buttons, sliders, dials) on the terminal display that replicate the functionality of physical control devices. These virtual control elements provide the same control capability as physical joysticks or buttons but exist purely in software, eliminating the need for additional physical hardware while maintaining full control functionality.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces mechanical control devices (joysticks, physical buttons) with software-based virtual control elements displayed on a terminal. The mechanical input-output system is substituted with an electronic interface where touch inputs on the display directly generate control signals, eliminating mechanical components while preserving control capability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Device complexity

If virtual control elements are used on terminal display, then device complexity is reduced, but ease of operation may worsen due to interface complexity

Engineering Contradiction:
Improvehardware complexityVSAvoiduser interface complexity
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The patent implements dynamic virtual control elements that can change their appearance, position, and behavior based on the current operational state of the agricultural machine. Control elements are dynamically created, modified, or removed from the interface based on contextual needs, allowing the interface to adapt to different operating modes and reduce cognitive load on the user.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent applies different visual and interactive characteristics to different control elements based on their specific function and current state. Each virtual control element can have unique properties such as color coding, size, position, and activation method tailored to its specific purpose, making the interface more intuitive and easier to operate despite the variety of controls available.

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If multiple control elements are mapped to auxiliary functions, then adaptability is improved, but device complexity increases

Engineering Contradiction:
Improvefunction mapping flexibilityVSAvoidcontrol system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a universal virtual control panel where a single set of software-based control elements can serve multiple auxiliary functions through configurable mapping. The same terminal display and virtual control elements can be adapted to control different functions by changing the mapping configuration, eliminating the need for separate control devices for each function while maintaining full adaptability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent enables flexible mapping between virtual control elements and auxiliary functions by allowing dynamic assignment of control parameters. The mapping relationship can be configured and changed without hardware modifications, enabling the same control interface to adapt to different operational requirements and function combinations through software parameter changes alone.

Inventive Principle:
Principle #35Parameter changes
