Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
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
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.
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.
3Reliability
If automated load detection system is implemented, then operator errors are prevented, but system complexity and cost increase
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.
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.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively minimizes operator errors and material damage by ensuring secure loading and transportation of sensitive loads, automatically activating brakes if the load is not secured within a set period, thus preventing damage and ensuring safe movement.
Implementation Method 1
measurement of total load of the vehicle by said EBS modulator via 'suspension pressure' value determined by the suspension air bags
Implementation Method 2
hydraulic cylinders activated via a hydraulic valve block... which receives a 'hydraulic pressure' information from said hydraulic valve block
Implementation Method 3
generates 'brake activation signal' which enables the EBS modulator to shift the brake to active or passive state
