Solution Overview

Problem

Meter panels in agricultural and construction machines, also referred to as work vehicles, face challenges in displaying a large amount of information, leading to decreased visibility and difficulty in obtaining necessary information, especially in smart agriculture and construction site operations.

Innovation Solution

An information display system for work vehicles that includes a meter panel unit with a display element and a control device, which displays information on operations needed to satisfy conditions for DPF regeneration when the vehicle does not meet those conditions, prioritizing travel-related operations and omitting already executed operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If more kinds of information are displayed on the meter panel, then the information completeness is improved, but the visibility decreases

Engineering Contradiction:
Improveinformation completenessVSAvoidvisibility
Core Design Contradiction:
Loss of informationVSIllumination intensity

Solution Approach 1:

The patent segments the meter panel into multiple display regions: a first display region for basic vehicle information and a second display region for additional information. This segmentation allows the panel to present comprehensive information while maintaining visibility by organizing content into distinct, manageable sections that can be selectively displayed based on operational context.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the meter panel displays all necessary information for various works, then the adaptability is improved, but the device complexity increases

Engineering Contradiction:
Improveinformation display capabilityVSAvoidmeter panel complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic display control where the meter panel adapts its information presentation based on the work vehicle's operational state. The control device selectively displays different types of information in the second display region depending on whether the vehicle is traveling or working, and adjusts display content based on satisfaction of DPF regeneration conditions. This dynamic adaptation provides versatile information display capability without requiring a permanently complex panel configuration.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If the meter panel provides detailed operational instructions, then the ease of operation is improved, but the information overload increases

Engineering Contradiction:
Improveuser guidanceVSAvoidinformation quantity
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The patent applies local quality by providing detailed operational instructions selectively in the second display region only when specific conditions are met (DPF regeneration required and conditions not satisfied). During normal operation, the panel displays only essential information in the first display region. This localized enhancement of information detail provides comprehensive guidance when needed while avoiding information overload during routine operations.

Inventive Principle:
Principle #3Local quality

AI summary

An information display system for a work vehicle includes a meter panel unit including a display element and a control device configured to control the meter panel unit. When a user operates a DPF regeneration switch that receives an instruction to execute DPF regeneration of the work vehicle, if the work vehicle does not satisfy conditions necessary for execution of the DPF regeneration, the control device causes the display element to display information relating to operations to be performed by the user for the work vehicle to satisfy the conditions.
