Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional arithmetic addition method is used to compute predicted steam supply amount, then calculation process is simple, but accuracy of predicted total steam supply amount becomes poor
Solution Approach 1:
The patent creates a virtual copy of the steam-using facility through simulation software, allowing complex steam flow calculations without physical modification of the actual facility. This virtual model replicates the facility's steam usage patterns, enabling accurate prediction of steam supply amounts after improvement measures are implemented, while avoiding the complexity of physical testing and measurement in the real system.
Solution Approach 2:
The simulation system dynamically adjusts multiple steam flow parameters (pressure, temperature, flow rate) to reflect different operational conditions and improvement scenarios. By changing these parameters within the virtual model, the system can accurately predict how steam supply amounts will change under various improvement approaches, providing precise measurements without altering the physical facility.
2Productivity
If steam usage state is made complicated through reuse of used steam, then facility efficiency is improved, but accuracy of predicted steam supply amount deteriorates
Solution Approach 1:
The simulation software creates a detailed virtual replica of the facility's steam usage system, including all steam reuse pathways and complex flow patterns. This virtual model captures the complicated steam usage state without requiring physical modification of the actual facility, allowing accurate predictions to be made while maintaining the facility's efficient steam reuse operations.
Solution Approach 2:
The simulation system incorporates feedback mechanisms that continuously adjust predicted steam supply amounts based on the complex steam usage patterns observed in the virtual model. By feeding back the simulated steam flow data and comparing it with actual facility performance, the system refines its predictions to maintain high accuracy even as the facility operates with complex steam reuse patterns.
3Ease of operation
If conventional arithmetic addition method is used, then evaluation process is simple, but evaluation accuracy of facility improving approach deteriorates
Solution Approach 1:
The simulation software creates a virtual copy of the facility that can be used to test and evaluate improvement approaches without affecting the actual facility operations. This virtual model allows multiple evaluation scenarios to be run simply by inputting different improvement measures, providing accurate evaluation results while maintaining ease of operation through automated simulation calculations.
Solution Approach 2:
The simulation system acts as an intermediary between the facility improvement evaluation process and the actual facility operations. Instead of directly analyzing complex steam usage data from the real facility, the system uses the virtual simulation model as an intermediate step to process and evaluate improvement approaches, simplifying the evaluation process while maintaining high accuracy through comprehensive virtual modeling.
