Solution Overview

Problem

Modern construction machines, such as hydraulic excavators, face challenges with increasingly complex control systems, leading to a cluttered and confusing control panel for operators, making it difficult to efficiently manage the growing number of controls.

Innovation Solution

A construction machine equipped with a control panel featuring a dynamically generable user interface, utilizing a touch-sensitive display to adapt the control layout based on the machine's operating mode and condition, hiding irrelevant controls to optimize clarity and reduce operator confusion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the number of controls in the control system is increased to provide more functions, then the functionality and automation support are improved, but the control panel becomes increasingly complex and confusing for the operator

Engineering Contradiction:
ImprovefunctionalityVSAvoidcontrol panel complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control panel uses a dynamically generated user interface that adapts its layout and content based on the current operating mode of the construction machine. The control unit detects mode changes and reconfigures the display accordingly, transforming the static control panel into a dynamic system that presents only mode-relevant controls, thereby maintaining simplicity while supporting multiple functions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The control panel interface is segmented into different configurations based on operating modes. Instead of presenting all controls simultaneously, the system divides the control set into mode-specific subsets, displaying only the relevant segment of controls for the current operating context, which reduces perceived complexity.

Inventive Principle:
Principle #1Segmentation

2Extent of automation

If more controls are added to the control panel to support increased automation, then the automation capability is improved, but the arrangement becomes scattered and difficult to access

Engineering Contradiction:
Improveautomation capabilityVSAvoidcontrol accessibility
Core Design Contradiction:
Extent of automationVSEase of operation

Solution Approach 1:

The control panel dynamically reconfigures its layout based on the active operating mode. Controls that are relevant to the current mode are positioned within easy reach of the operator, while irrelevant controls are hidden or marked. This dynamic adaptation ensures that automation capabilities are maintained while preserving ergonomic accessibility.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system extracts and displays only the subset of controls that are relevant to the current operating mode, removing unnecessary controls from the active display. This extraction approach maintains ease of operation by presenting a simplified control set while keeping the full automation capability available through mode switching.

Inventive Principle:
Principle #2Taking out (Extraction)

3Loss of information

If all controls are always displayed on the control panel, then complete information availability is improved, but operator confusion and the risk of incorrect control selection increase

Engineering Contradiction:
Improveinformation availabilityVSAvoidoperator confusion
Core Design Contradiction:
Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The control panel dynamically adjusts its display content based on the current operating mode. Controls relevant to the active mode are displayed prominently, while irrelevant controls are hidden or marked as unavailable. This dynamic information filtering maintains operational clarity while preserving access to complete system functionality through mode transitions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Different regions or states of the control panel have different information quality characteristics. The active operating mode determines which controls are presented with full functionality, while other controls are dimmed, hidden, or marked as unavailable. This local differentiation of information quality reduces operator confusion while maintaining overall system transparency.

Inventive Principle:
Principle #3Local quality
