Solution Overview

Problem

In dynamic work environments like mining and construction, existing systems struggle to effectively collect and analyze changes in topography and machine operations, leading to suboptimal machine control and potential damage due to unawareness of environmental changes.

Innovation Solution

A worksite management system that tracks machine positions and operational parameters, segments routes into topographic segments, and generates feedback to operators for improved performance and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If data collection systems are implemented to monitor work environment changes, then operator awareness and machine control improve, but system complexity and implementation cost increase

Engineering Contradiction:
Improvemachine controlVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system continuously collects data from sensors monitoring work environment parameters (topography, weather, machine operation) and provides feedback to operators through displays. This feedback loop enables operators to adjust machine operations in real-time based on detected environmental changes, improving machine control reliability without requiring overly complex centralized systems.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent introduces an intermediary data collection and analysis system that bridges the gap between raw environmental sensors and operator decision-making. This intermediary layer processes sensor data, identifies meaningful patterns, and presents actionable information to operators, reducing the complexity burden while maintaining improved machine control.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If comprehensive monitoring systems are deployed to track all work environment changes, then data accuracy improves, but implementation cost increases

Engineering Contradiction:
Improvedata accuracyVSAvoidimplementation cost
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The monitoring system is segmented into multiple independent sensor units distributed across the worksite, each measuring specific parameters (topography, weather, machine operation). This segmentation allows for targeted data collection where precision is most needed while reducing overall system cost compared to a comprehensive centralized monitoring approach.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically adjusts monitoring parameters and data collection frequency based on operational conditions. During critical operations or when environmental changes are detected, measurement precision is increased. During stable conditions, monitoring intensity is reduced, optimizing the balance between data accuracy and implementation cost.

Inventive Principle:
Principle #35Parameter changes
