1Ease of operation
If cargo loading systems operate based on global and constant parameters, then system operation is simplified, but flexibility and efficiency deteriorate when operational conditions deviate from planned conditions
Solution Approach 1:
The patent implements dynamic parameter adjustment by continuously monitoring actual operating conditions (such as electrical power availability, cargo weight, and system state) and adapting the conveying speed and power consumption of transport devices in real-time. This replaces static, pre-programmed parameters with dynamic, condition-based control, allowing the system to efficiently adapt to varying operational conditions while maintaining streamlined operation through automated control.
Solution Approach 2:
The system incorporates feedback mechanisms by monitoring actual operating parameters (electrical power, conveying speed, system state) and using this information to continuously adjust control decisions. The control device receives feedback from sensors and measuring devices, evaluates current conditions, and modifies operational parameters accordingly, creating a closed-loop control system that balances simplicity with adaptability.
2Speed
If transport devices switch to conveying mode with nominal operating power, then conveying speed is maximized, but load peaks occur during operation
Solution Approach 1:
The patent implements staged power activation where transport devices do not switch instantly to full nominal power, but rather increase power consumption in controlled stages or periods. This periodic or progressive power application smooths out electrical load peaks while still achieving the required conveying speed over time, balancing immediate speed requirements with electrical system capacity.
Solution Approach 2:
The system dynamically adjusts the power consumption profile of transport devices based on actual electrical power availability and system conditions. Instead of fixed nominal power switching, the control device modulates power delivery dynamically, allowing conveying speed to be achieved while adapting power consumption to prevent load peaks on the electrical infrastructure.
3Productivity
If multiple transport devices switch to conveying mode simultaneously, then loading efficiency is maximized, but electrical infrastructure requires powerful safety elements increasing costs and complexity
Solution Approach 1:
The patent segments the activation of multiple transport devices by controlling them to switch to conveying mode in a staggered or sequential manner rather than simultaneously. This segmentation of the loading process across time and individual devices maintains overall loading efficiency while distributing electrical power demand, thereby reducing the need for oversized safety elements and simplifying electrical infrastructure requirements.
Solution Approach 2:
The control device implements periodic or staged activation of transport devices, where multiple devices are switched to conveying mode at different time intervals rather than all at once. This periodic activation pattern maintains productivity by ensuring continuous loading operations while smoothing out peak power demands, reducing electrical infrastructure complexity and costs.
4Productivity
If conveying speed is increased to improve loading time, then productivity increases, but mechanical wear and energy consumption increase
Solution Approach 1:
The patent implements dynamic speed adjustment where conveying speed is continuously adapted based on actual operating conditions such as cargo weight, electrical power availability, and system state. Rather than operating at constant high speed, the system optimizes speed in real-time, maintaining high productivity when conditions permit while reducing speed (and thus energy consumption and wear) when conditions require conservation, achieving an optimal balance throughout the loading process.
