Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless communication apparatus uses a higher frequency band (5.0 GHz) for communication, then communication speed and stability are improved, but the likelihood of radio wave interference increases and communication range decreases
Solution Approach 1:
The patent implements dynamic frequency band selection where the wireless communication apparatus automatically switches between 2.4 GHz and 5.0 GHz bands based on real-time detection of supported devices and communication conditions. The frequency band selection unit dynamically adapts the operating frequency based on apparatus information obtained from information processing apparatuses, ensuring optimal communication stability while minimizing interference.
Solution Approach 2:
The system changes the operating frequency parameter based on detected conditions. The frequency band selection unit modifies the frequency band parameter (2.4 GHz or 5.0 GHz) according to apparatus information, allowing the communication system to adapt to different environmental conditions and device capabilities, thereby resolving the contradiction between communication stability and interference reduction.
2Ease of operation
If the wireless communication apparatus automatically selects frequency band, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The wireless communication apparatus performs self-service by automatically obtaining apparatus information from information processing apparatuses and autonomously selecting the appropriate frequency band without user intervention. The apparatus information obtaining unit and frequency band selection unit work together to enable the system to make its own decisions regarding frequency band selection, improving ease of operation.
Solution Approach 2:
The patent introduces an intermediary mechanism in the form of apparatus information exchange protocols that facilitate automatic frequency band selection. By using standardized information obtaining methods, the system mediates between different devices and automatically determines compatible frequency bands, managing complexity through structured communication protocols.
3Productivity
If the wireless communication apparatus uses 5.0 GHz band for all communications, then communication speed is improved, but adaptability to different information processing apparatuses decreases
Solution Approach 1:
The system dynamically adapts its operating frequency based on the capabilities of connected information processing apparatuses. The frequency band selection unit adjusts between 2.4 GHz and 5.0 GHz bands in real-time according to apparatus information, ensuring both high-speed communication when possible and broad compatibility when needed.
Solution Approach 2:
The wireless communication apparatus is designed with multi-functionality to operate in both 2.4 GHz and 5.0 GHz frequency bands. This universal capability allows the system to maintain high communication speed with 5.0 GHz when supported, while also ensuring adaptability and compatibility with apparatuses that only support 2.4 GHz, thus resolving the contradiction between speed and versatility.
