Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If expert experience-based adjustment methods are used, then the weighing device can be operated, but the adjustment process is cumbersome and time-consuming
Solution Approach 1:
The system enables self-service by allowing the weighing device to automatically adjust its own parameters through the reinforcement learning model. The model continuously learns from packaging results and autonomously modifies parameters without requiring expert intervention, making the system self-optimizing and eliminating the time-consuming manual adjustment process
Solution Approach 2:
The patent replaces the mechanical expert-based adjustment system with an intelligent software system. Instead of relying on human experts to manually tune parameters based on experience, the system uses a reinforcement learning model that processes packaging results and automatically generates parameter adjustments, substituting human cognitive processes with computational algorithms
2Adaptability or versatility
If traditional adjustment methods are used, then the weighing device operates, but environmental factors are not effectively integrated
Solution Approach 1:
The system implements comprehensive feedback mechanisms by continuously monitoring packaging results and environmental conditions. The reinforcement learning model receives feedback about actual packaging outcomes and uses this information to adjust parameters in real-time, creating a closed-loop control system that adapts to changing environmental factors while maintaining reliable give-away rate control
Solution Approach 2:
The system transitions from static, fixed parameters to dynamic, adaptive parameters. The reinforcement learning model continuously updates parameters based on real-time environmental conditions and packaging performance, making the system flexible and responsive to changing circumstances rather than relying on predetermined fixed settings
3Loss of substance
If manual parameter adjustment is used, then the process is simple, but the average give-away rate remains excessively high
Solution Approach 1:
The system systematically changes multiple parameters simultaneously based on reinforcement learning insights. Instead of adjusting single parameters in isolation, the model optimizes a combination of parameters including packaging weight, sealing temperature, and timing, allowing for comprehensive optimization that significantly reduces give-away rates despite the increased complexity of managing multiple parameters
