Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional algorithms are used to calculate stowage patterns, then the calculation process is simple, but the ability to handle randomly conveyed articles and achieve stable stacking is insufficient
Solution Approach 1:
The patent applies vibration to the containing region during the stowage pattern calculation process. By adding vibration to the physical model of the containing region, the system simulates real-world conditions and calculates how articles settle and stabilize under vibrational forces, thereby determining a more reliable stowage pattern that accounts for dynamic settling behavior
Solution Approach 2:
The patent replaces conventional algorithm-based calculation methods with a physics-based simulation approach. Instead of using mathematical algorithms to determine stacking patterns, the system uses physical models that incorporate forces, gravity, and vibration to naturally simulate how articles settle, providing more reliable results for randomly conveyed articles
2Manufacturing precision
If physical calculation with vibration is applied, then the stowage pattern accuracy improves, but the calculation time increases
Solution Approach 1:
The patent performs preliminary actions by pre-defining the physical models of articles and the containing region, including their dimensions, weights, and material properties. By preparing these models in advance with all necessary physical parameters, the system reduces the computational burden during the actual stowage calculation, allowing for accurate physics-based simulation without excessive calculation time
Solution Approach 2:
The patent changes key parameters during the calculation process, specifically adding vibration parameters to the physical model. By dynamically introducing vibrational forces and adjusting physical parameters during simulation, the system achieves accurate stowage patterns that reflect real-world settling behavior while maintaining computational efficiency through targeted parameter modification
