Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If expert manually tunes the microwave filter, then the desired performance is achieved, but the personnel cost and time required increase significantly
Solution Approach 1:
The patent creates a golden filter that has been pre-tuned to desired performance specifications. This pre-tuned filter serves as a reference template that eliminates the need for time-consuming expert manual tuning of subsequent filters. The golden filter's tuning parameters are replicated across multiple production units, achieving consistent performance without repeated expert intervention.
Solution Approach 2:
The patent uses the golden filter as a master template to copy its tuning characteristics to other filters. By measuring and replicating the tuning screw positions and configurations from the golden filter, subsequent filters achieve the same performance characteristics through copying rather than manual expert adjustment, significantly reducing time and cost.
2Manufacturing precision
If expert manually tunes the microwave filter, then the desired performance is achieved, but the personnel cost increases
Solution Approach 1:
The golden filter serves as a reusable master template that can be copied to produce multiple identical filter configurations. This eliminates the need for expensive expert manual tuning for each individual filter, as the tuning parameters are systematically replicated from the golden filter, reducing personnel costs while maintaining performance consistency.
Solution Approach 2:
The system enables self-service tuning by using the golden filter as an automatic reference standard. Instead of requiring expert judgment for each filter, the golden filter provides objective measurement references that guide the tuning process, allowing non-experts to achieve consistent results through systematic replication of the golden filter's parameters.
3Productivity
If initial tuning is performed using a golden filter reference, then tuning time is reduced, but the accuracy may be insufficient without expert final tuning
Solution Approach 1:
The system copies the precise tuning parameters from the golden filter to create initial configurations for multiple filters. This copying process maintains high accuracy by directly replicating the golden filter's proven performance parameters, eliminating the need for additional expert refinement while preserving tuning precision.
Solution Approach 2:
The golden filter undergoes comprehensive preliminary tuning to establish optimal parameters before mass production. This pre-established reference ensures that subsequent filters receive accurate initial configurations, achieving both high productivity through rapid replication and high precision through the golden filter's optimized parameters.
