Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If WLAN or Bluetooth radio transmission is used for data communication, then cable connections are eliminated and devices can communicate wirelessly, but the transmission speed decreases and the system becomes susceptible to radio interference and unpredictable response times
Solution Approach 1:
The system segments the wireless communication into dedicated point-to-point links between adjacent devices rather than a shared multi-access network. Each transmission path is isolated and dedicated, eliminating the need for channel arbitration and enabling deterministic real-time communication.
Solution Approach 2:
The patent applies local quality by creating localized communication zones between adjacent devices using directional antennas. Each communication link is confined to a specific spatial region, preventing interference from other links and enabling reliable wireless transmission at cable-like speeds.
2Adaptability or versatility
If WLAN multi-access networks are used with multiple participants sharing bandwidth, then wireless connectivity is achieved, but channel arbitration and collision detection mechanisms make response times unpredictable and prevent real-time transmission
Solution Approach 1:
The network is segmented into independent point-to-point communication links between adjacent devices. Each link operates autonomously without sharing bandwidth with other links, eliminating the need for channel arbitration and enabling predictable real-time response times.
Solution Approach 2:
The patent extracts the channel arbitration and collision detection mechanisms from the communication system by using dedicated point-to-point links. This removal of unnecessary overhead enables deterministic transmission without the time losses associated with multi-access protocol management.
3Reliability
If conventional cables and plugs are used for data transmission, then reliable connection is achieved, but the connectors are susceptible to mechanical damage, dirt, corrosion, and oxidation leading to malfunctions and failures in harsh environments
Solution Approach 1:
The patent replaces the mechanical cable and connector system with a wireless communication system using directional antennas. This substitution eliminates all mechanical contact points that are susceptible to damage, dirt, corrosion, and oxidation, while maintaining reliable data transmission in harsh food production environments.
4Speed
If directional antennas with mechanical coupling are used for point-to-point wireless communication, then real-time data transmission is achieved with predictable response times, but the system requires precise alignment and shielding to prevent environmental interference
Solution Approach 1:
The patent applies preliminary action by pre-aligning the directional antennas during device installation and positioning the shielding structures before operation. This preliminary setup ensures optimal communication performance without requiring complex real-time adjustment mechanisms, reducing operational complexity while maintaining real-time transmission capabilities.
