Multi-Vehicle Load Position Optimization via Dynamic Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transportation systems are limited in their operational range and stability when handling large or heavy loads, particularly in off-road or unstable conditions, as they struggle to maintain load balance and distribution effectively across multiple vehicles.
Innovation Solution
An arrangement comprising a master vehicle and slave vehicles, equipped with platforms, actuating devices, and sensing systems, which generate and transmit controlling commands to manage load position and balance by adjusting the platform's movement in relation to the vehicles, ensuring the load's center of gravity remains within a specific area, even in challenging terrains.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single transportation vehicle is used, then the device complexity is low, but the capability to transport heavy or long loads is insufficient
Solution Approach 1:
The transportation system is segmented into multiple independent vehicles (master vehicle and slave vehicles), each capable of carrying portions of the load. This segmentation allows the system to handle heavy or long loads that exceed the capacity of a single vehicle, while maintaining relatively simple individual vehicle designs.
Solution Approach 2:
Multiple transportation vehicles are merged into a coordinated system where they work together to transport a common load. The vehicles are coupled through the load itself, creating a combined transportation capability that exceeds individual vehicle capacities while sharing the complexity burden across multiple units.
2Quantity of substance
If multiple transportation vehicles are used to transport heavy loads, then the load capacity increases, but the stability and load balance control becomes more difficult
Solution Approach 1:
Sensing devices are installed on each vehicle to detect the actual load position and center of gravity in real-time. This feedback information is transmitted to controlling devices that calculate the optimal load distribution, enabling continuous adjustment to maintain stability despite terrain variations or load shifts.
Solution Approach 2:
The system dynamically adjusts load distribution across multiple vehicles based on real-time conditions rather than using fixed allocation. The controlling devices continuously recalculate optimal positions and transmit new commands, allowing the system to adapt to changing terrain, vehicle positions, and load characteristics to maintain stability.
3Adaptability or versatility
If shock absorbers are used for vehicle balancing, then the vehicle can handle rough terrain, but the operational range and load stability are limited
Solution Approach 1:
An intermediary control system is introduced between the vehicles and the load, consisting of sensing devices that monitor load position and controlling devices that calculate optimal distribution. This intermediary layer coordinates the vehicles' actions to maintain load stability, going beyond what passive shock absorbers can achieve by actively managing load position across the entire vehicle system.
