Solution Overview

Problem

Industrial trucks with load-carrying devices for picking up long goods lack a safety control that effectively meets their specific requirements, leading to inadequate protection and operational efficiency.

Innovation Solution

An industrial truck equipped with a long goods detection device and a safety controller that uses monitoring sensors to dynamically adjust a protective field based on detected long goods, ensuring safe operation by reducing speed or stopping when approaching vehicles or people, and adapting to the overall contour of the truck and load.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fixed-size protective field is used for industrial trucks, then safety monitoring is simplified, but the protective field becomes excessively large when handling long goods, reducing operational efficiency

Engineering Contradiction:
Improvesafety protectionVSAvoidoperational efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The protective field is made dynamic by continuously adapting its size and shape to the actual load configuration. The safety controller receives data from the long goods detection device about the load's length and position, then adjusts the protective field parameters in real-time. This allows the protective field to be large only when long goods are present and small when they are not, resolving the contradiction between safety and efficiency

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the parameters of the protective field (size, shape, position) based on the detected long goods characteristics. When long goods are detected, the protective field parameters are adjusted to cover the extended area; when no long goods are present, the parameters return to standard dimensions. This parameter adaptation enables both high safety when needed and high efficiency when not needed

Inventive Principle:
Principle #35Parameter changes

2Reliability

If a large protective field is maintained for all operations, then safety is maximized, but the truck's movement is unnecessarily restricted during normal operations, reducing operational smoothness

Engineering Contradiction:
Improvesafety protectionVSAvoidoperational smoothness
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The protective field dynamically adapts its boundaries based on the actual operational context. When long goods are detected, the protective field expands to ensure safety; when no long goods are present, the protective field contracts to minimal necessary dimensions. This dynamic behavior ensures safety is maximized only when required, while operational smoothness is maintained during normal operations

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system modifies the protective field parameters (extent, position, shape) according to the detected load conditions. The safety controller adjusts these parameters in real-time based on feedback from the long goods detection device, ensuring the protective field is as large as needed for safety but not larger, thereby maintaining operational smoothness

Principle #35Parameter changes
