Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If strict management of manufacturing status is implemented, then product quality and static elimination status can be monitored, but management burden increases
Solution Approach 1:
The static eliminator autonomously performs measurement value acquisition, history data generation, and storage without requiring external monitoring systems. The device self-manages its operation data by automatically recording ion balance measurements, generating history data with timestamps, and storing it in nonvolatile memory, thereby eliminating the need for complex external management infrastructure
Solution Approach 2:
The device incorporates a feedback mechanism where measurement values related to ion balance control are automatically acquired, processed into history data, and stored for future reference. This closed-loop feedback system enables continuous monitoring of static elimination status while keeping the management process integrated within the device itself
2Manufacturing precision
If manual monitoring of static elimination is performed, then static electricity can be controlled, but labor requirements and management complexity increase
Solution Approach 1:
The patent replaces manual mechanical monitoring operations with an automated electronic measurement and data processing system. The static eliminator automatically acquires measurement values, processes them into history data with timestamps, and stores them in nonvolatile memory, eliminating the need for manual observation and recording operations
Solution Approach 2:
The measurement value acquisition unit and data generation unit serve as intermediaries between the ion generation unit and the storage unit. These intermediary components automatically translate raw measurement data into structured history data with timestamps, facilitating seamless data flow without requiring manual intervention
