Solution Overview

Problem

Working machines often operate in risky environments where operators are overloaded with irrelevant information, increasing the risk of accidents and injuries due to the lack of selective image data display based on both machine parameters and environmental conditions.

Innovation Solution

A system that determines the position of movable units relative to risk zones in the working machine's environment and selectively displays image data from cameras when the unit is within these zones, using position determination means and a control unit to manage display content.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If image data from multiple cameras are continuously displayed to provide comprehensive environmental awareness, then safety and situational awareness are improved, but operator information overload increases and attention is分散

Engineering Contradiction:
ImprovesafetyVSAvoidinformation overload
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The display system segments the comprehensive image data from multiple cameras into separate, selectable views. Instead of showing all camera feeds simultaneously which would overload the operator, the system divides the information into discrete segments that can be individually activated based on operational context, allowing the operator to focus on relevant areas without being overwhelmed by unnecessary visual information.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The display configuration dynamically adapts based on the movable unit's position and operational state. The system automatically adjusts which camera views are displayed by evaluating real-time position data against predefined risk zones, transitioning between different display modes as the operator moves through different spatial contexts, thereby optimizing information relevance without manual intervention.

Inventive Principle:
Principle #15Dynamics

2Reliability

If all camera views are displayed simultaneously to ensure complete environmental monitoring, then comprehensive safety coverage is achieved, but the operator cannot focus on critical risk areas and information relevance decreases

Engineering Contradiction:
Improvesafety coverageVSAvoidinformation relevance
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The system applies local quality by providing enhanced visual information specifically in risk zone areas rather than uniformly displaying all views. When the movable unit enters a predefined risk zone, the system automatically prioritizes and highlights image data from cameras monitoring that specific area, giving local emphasis to critical regions while maintaining the option to access other views when needed.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system implements feedback by continuously monitoring the position of the movable unit and automatically adjusting the display content based on real-time spatial context. Position data feeds back into the control logic which then modifies which camera views are active, creating a closed-loop system that adapts information presentation to match actual operational risks and maintains information relevance throughout the work cycle.

Inventive Principle:
Principle #23Feedback

3Device complexity

If the system displays image data based only on machine parameters without considering environmental context, then device complexity is reduced, but the system cannot adapt to specific risk situations and safety effectiveness decreases

Engineering Contradiction:
Improvecontrol logicVSAvoidsafety effectiveness
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The system employs preliminary action by pre-defining risk zones and associating specific camera views with particular spatial regions before operation begins. These predefined zones and view associations are configured in advance based on the working environment and potential hazard locations, allowing the system to quickly activate appropriate displays without complex real-time analysis, thereby balancing simplicity with adaptive safety effectiveness.

Inventive Principle:
Principle #10Preliminary action

AI summary

The invention relates to a system (300) and a method (400) for selectively displaying image data in a working machine (100, 500, 600). The working machine comprises a movable unit (102, 104, 106, 108, 502, 504, 506, 602), which is movable in relation to a ground portion (120) of the working machine. The working machine further comprises an image capturing arrangement (124) and a display (128) adapted to display image data captured by the image capturing arrangement. The system comprises a position determination means (302), adapted to determine a position of the movable unit. The system further comprises a control unit (304) configured to compare the position of the movable unit to a risk zone (200, 202) associated with a current environment of the working machine and to issue a signal to the working machine to display image data of the risk zone captured by the image capturing arrangement on the display, when the position of the movable unit is within the risk zone. The invention also relates to a working machine (100, 500, 600) comprising the system (300).
