Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a control temperature table is experimentally obtained for each drying condition (load, temperature, fabric, water content), then the drying temperature control precision is improved, but the device complexity and memory burden increase significantly
Solution Approach 1:
The patent applies universality by creating a single control temperature table that can be adaptively used across multiple drying conditions (different loads, temperatures, fabric types, and water contents). Instead of maintaining separate control tables for each condition, the system uses one universal table that is dynamically adjusted based on real-time sensor feedback, thereby reducing memory burden while maintaining temperature control precision.
Solution Approach 2:
The patent employs parameter changes by dynamically adjusting the control temperature table based on varying drying conditions. The system monitors parameters such as load size, temperature, fabric type, and water content, then modifies the control temperature values accordingly. This allows the single control table to adapt to different scenarios, maintaining precision without requiring separate tables for each condition.
2Reliability
If extensive experimentation is conducted to obtain control temperature tables for all drying situations, then the reliability of temperature control is improved, but the loss of time and productivity decrease
Solution Approach 1:
The patent applies preliminary action by pre-establishing a single universal control temperature table that can handle multiple drying conditions. Instead of conducting extensive separate experiments for each condition, the system prepares one robust control table in advance that is designed to be adaptable through parameter adjustments, thereby reducing development time while maintaining reliability.
Solution Approach 2:
The system employs self-service by using real-time sensor feedback to automatically adjust the control temperature table parameters during operation. The system monitors drying conditions and autonomously modifies control parameters without requiring manual reconfiguration or additional experimentation, thereby maintaining reliability while improving development efficiency and operational flexibility.
3Adaptability or versatility
If multiple control temperature tables are configured for different drying conditions, then the adaptability to various situations is improved, but the device complexity and memory requirements increase
Solution Approach 1:
The patent applies universality by designing a single control temperature table that serves multiple drying conditions. The table is structured to be universally applicable across different loads, temperatures, fabric types, and water contents through dynamic parameter adjustment, eliminating the need for multiple separate tables and thereby reducing system complexity while maintaining adaptability.
Solution Approach 2:
The patent employs dynamics by making the control temperature table flexible and adjustable in real-time based on drying conditions. Instead of using static separate tables for each condition, the system dynamically modifies the single control table's parameters according to sensor feedback, enabling adaptability to various situations without increasing system complexity.
