Solution Overview

Problem

Operator errors in securing sensitive loads during transportation in inloader vehicles often result in damage due to the lack of automated control mechanisms in existing hydraulic securing systems, leading to material losses.

Innovation Solution

A load safety system that includes hydraulic cylinders activated via a hydraulic valve block, suspension air bags, and an EBS modulator, with an electronic control unit that automatically secures loads by comparing hydraulic pressure to ideal values and generates brake activation signals to prevent movement if the load is not properly secured within a defined time frame.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If hydraulic securing systems are used to support and hold loads, then load transportation is effective and trouble-free, but operator errors occur when the system is not activated, leading to load damage

Engineering Contradiction:
Improveload securing reliabilityVSAvoidoperator operation complexity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system automatically detects when a load is placed on the vehicle through suspension pressure sensors and autonomously activates the hydraulic securing mechanism without requiring operator intervention. The system serves itself by monitoring its own operational state and triggering security measures automatically.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Pressure sensors continuously monitor the suspension system to detect load presence, and this feedback information is used by the control unit to determine when to activate the hydraulic cylinders. The system uses real-time pressure data to adjust its security operations dynamically.

Inventive Principle:
Principle #23Feedback

2Device complexity

If manual activation of hydraulic securing system is used, then system structure remains simple, but operator forgetfulness leads to lateral forces on load during transportation

Engineering Contradiction:
Improvesystem structure complexityVSAvoidload securing reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The system performs preliminary detection of load presence through suspension pressure sensors before transportation begins. By detecting the load in advance and automatically activating the securing mechanism, the system prevents the harmful effect of unsecured loads during movement without requiring complex manual procedures.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The manual mechanical activation process is replaced with an automated electronic control system that uses pressure sensors and electronic control units to trigger the hydraulic mechanism. This substitution eliminates operator error while maintaining relatively simple system architecture.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If automated load detection system is implemented, then operator errors are prevented, but system complexity and cost increase

Engineering Contradiction:
Improveload securing reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The suspension pressure sensors serve dual purposes: they monitor both the vehicle's suspension system performance and detect the presence of loads for security activation. By making the sensing system multi-functional, the patent avoids adding separate detection devices and keeps the overall system complexity manageable.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The load detection function is merged with the existing suspension system rather than being implemented as a separate device. The control unit integrates information from the suspension pressure sensors to automatically control the hydraulic securing mechanism, combining multiple functions into a unified system.

Inventive Principle:
Principle #5Merging (Combining)
