Solution Overview

Problem

Existing crane operations require operators to frequently shift their attention between the crane and a remote control, compromising safety and introducing operational inconveniences due to the need for continuous status monitoring.

Innovation Solution

A crane equipped with lighting devices that visualize its status and the vehicle's status using sensor data, controlled by visualization control circuitry to emit light based on sensor inputs, allowing continuous observation without diverting attention from the crane.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the operator uses a remote control to operate the crane, then the operator can control the crane from a distance, but the operator must frequently shift attention between the crane and the remote control, compromising safety

Engineering Contradiction:
Improveremote control operationVSAvoidoperator safety
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent uses color-changing LED lights mounted on the crane to indicate operational status (e.g., green for safe operation, yellow for warning, red for danger). This allows the operator to monitor crane status at a glance without diverting attention from the work area, resolving the contradiction between remote control operation and operator safety

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The system provides real-time visual feedback through status lights that reflect the current operational state of the crane. This continuous feedback loop enables the operator to maintain awareness of crane status while operating from a distance, eliminating the need to frequently check the remote control display

Inventive Principle:
Principle #23Feedback

2Loss of information

If the operator monitors the remote control display for status information, then the operator receives detailed status data, but the operator cannot continuously observe the crane, introducing operational inconveniences

Engineering Contradiction:
Improvestatus informationVSAvoidcontinuous observation
Core Design Contradiction:
Loss of informationVSProductivity

Solution Approach 1:

Different colors of status lights convey different levels of information about crane operation (e.g., green indicates normal operation, yellow indicates warning conditions, red indicates critical errors). This color-coded information system provides comprehensive status data through a single visual indicator, allowing continuous observation without sacrificing information quality

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The status information is segmented into distinct visual indicators for different crane components and functions. Each light or set of lights represents specific operational parameters, allowing the operator to quickly assess overall status and specific issues without needing to interpret complex display data

Inventive Principle:
Principle #1Segmentation
