Engineering Contradiction Analysis
1Adaptability or versatility
If a counter unit has three-phase or two-phase input channels, then it can count multi-phase pulse signals, but unused input terminals are generated when connected to single-phase output apparatuses
Solution Approach 1:
The counter unit is designed with multi-functional input channels that can operate in different modes. Each input channel can function as a three-phase counter, two-phase counter, or single-phase counter based on the connected output apparatus type, making the device universally compatible with single-phase, two-phase, and three-phase output apparatuses without leaving input terminals unused
Solution Approach 2:
The counter unit dynamically adapts its input channel configuration based on the connected output apparatus. The system can switch between three-phase mode, two-phase mode, and single-phase mode, allowing the input terminals to be actively utilized according to the actual signal type received, thereby eliminating waste of input terminals while maintaining compatibility with various output apparatuses
2Productivity
If a counter unit has fixed three-phase or two-phase input configuration, then it is optimized for multi-phase signals, but it cannot efficiently utilize input terminals when connected to single-phase output apparatuses
Solution Approach 1:
The input channels are designed with universal functionality to handle single-phase, two-phase, and three-phase signals. The counter unit can efficiently count pulses from any output apparatus type by adapting its internal configuration, ensuring high counting efficiency is maintained across all signal types while providing the flexibility to work with diverse output apparatuses
Solution Approach 2:
The counter unit dynamically reconfigures its input channels based on the detected signal type. When connected to a single-phase output apparatus, the system activates single-phase counting mode; for two-phase apparatuses, it switches to two-phase mode; and for three-phase apparatuses, it uses three-phase mode. This dynamic adaptation ensures optimal counting efficiency for each signal type while maintaining versatility across different applications
