Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an LSI circuit with configuration pins is used to control encoder operation, then the encoder can be configured for different types of operations, but the LSI circuit cannot be made smaller and the encoder size is limited
Solution Approach 1:
The configuration function is extracted from the LSI circuit and implemented separately in the microcontroller through software. The LSI circuit is reduced to essential components only, while the microcontroller handles configuration tasks via program execution, allowing the LSI circuit to be minimized without sacrificing configurability
Solution Approach 2:
A single LSI circuit design is made universal by combining it with a programmable microcontroller. The same LSI circuit can support multiple encoder types and configurations through software programming, eliminating the need for different LSI circuit designs for different applications
2Adaptability or versatility
If separate programs are written into the microcontroller for different types of encoders, then each encoder type can be properly configured, but additional manufacturing time and man-hours are required
Solution Approach 1:
Instead of creating different programs for different encoder types, a single program uses parameter changes based on detected voltage levels. The microcontroller reads voltage levels from configuration terminals and adjusts operational parameters dynamically, allowing one program to configure multiple encoder types without additional manufacturing steps
Solution Approach 2:
The microcontroller automatically determines the appropriate configuration by detecting voltage levels at configuration terminals during operation. This self-configuration capability eliminates the need for manual program selection or editing during manufacturing, improving productivity while maintaining adaptability
