Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If game software is configured to process only general-purpose game controller signals, then software compatibility and reliability are improved, but adaptability to dedicated controllers deteriorates
Solution Approach 1:
The patent introduces a signal conversion unit as an intermediary component that translates dedicated controller signals into general-purpose controller signals. This mediator enables communication between incompatible systems without requiring changes to the existing game software, thus maintaining reliability while achieving adaptability.
Solution Approach 2:
The conversion unit changes the parameter format of control signals from dedicated controller protocols to standard game controller protocols. By transforming signal parameters including button press data, analog stick positions, and trigger states into universally recognized formats, the system achieves broad compatibility.
2Adaptability or versatility
If a conversion processing unit is added to enable dedicated controller support, then adaptability is improved, but device complexity increases
Solution Approach 1:
The conversion processing unit is designed with multi-functionality to handle various types of dedicated controllers (gun controllers, dance controllers, etc.) through a single unified interface. By implementing universal signal reception and conversion capabilities, the system avoids the need for separate conversion modules for each controller type, thereby limiting the increase in complexity.
3Ease of operation
If motion sensor data is converted into analog stick signals, then ease of operation is improved, but measurement precision requirements increase
Solution Approach 1:
The conversion unit implements feedback mechanisms that continuously monitor the relationship between motion sensor inputs and generated analog stick signals. By adjusting conversion parameters based on detected motion patterns and user behavior, the system optimizes the mapping relationship to maintain precision while preserving intuitive operation.
