Solution Overview

Problem

Agricultural working machines face challenges in coordinating the functions of plug connections and controls, leading to potential malfunctions due to unclear assignments between operating elements and coupling elements, requiring complex procedures to ensure accurate operation.

Innovation Solution

The implementation of visual identification features on both operating elements and coupling elements, such as toggle switches and hydraulic remote connections, with input means to establish operative connections and adaptive color LED indicators to simplify the assignment process without requiring program changes or additional data entry.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If visual identification features are provided on operating elements and coupling elements to improve assignment clarity, then assignment errors are avoided and ease of operation is improved, but device complexity increases due to additional visual identification components

Engineering Contradiction:
Improveassignment clarityVSAvoidvisual identification components
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies color-coded visual identification features on operating elements and coupling elements. Each operating element (e.g., joystick, pedal) and corresponding coupling element is assigned a specific color that matches between them, enabling the driver to intuitively identify correct assignments without complex electronic displays or additional data entry procedures.

Inventive Principle:
Principle #32Color changes

2Reliability

If centralized electronic control systems are used to manage plug connection assignments, then functional coordination is achieved, but operation time increases due to required display switching and data entry

Engineering Contradiction:
Improvefunctional coordinationVSAvoidoperation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The visual identification system enables the driver to independently and immediately identify correct operating element-coupling element assignments through color coding. This eliminates the need to access centralized electronic control systems, switch display modes, or perform data entry procedures, thereby reducing operation time while maintaining reliable functional coordination.

Inventive Principle:
Principle #25Self-service

3Loss of information

If detailed display information is provided on central electronic devices, then complete functional information is available, but ease of operation deteriorates due to spatial separation and complex interaction requirements

Engineering Contradiction:
Improvefunctional information completenessVSAvoidintuitive operation
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent segments the functional information delivery system into distributed visual identification features placed directly on or near each operating element and coupling element. Instead of requiring the driver to access a centralized electronic display, each control element has its own visual identifier (color code) that provides immediate local information about its assignment, making the system both information-complete and intuitively operable.

Inventive Principle:
Principle #1Segmentation
