Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If user entry devices are fixedly installed to provide access control, then access control functionality is ensured, but flexibility in placement and adaptability to changing environments is limited
Solution Approach 1:
The gate device is transformed from a fixed structure to a movable one by equipping it with a motor (260) and wheels, allowing it to be repositioned freely within the environment while maintaining its access control functionality through wireless communication with the external system
Solution Approach 2:
The fixed mechanical installation system is replaced with a wireless communication system. The gate device communicates with the external system via wireless technologies (WLAN, PAN, or cellular network) eliminating the need for fixed mechanical mounting infrastructure
2Adaptability or versatility
If user entry devices are fixedly installed, then stable access control is provided, but relocation and repositioning capability is lost
Solution Approach 1:
The gate device is designed with universal functionality to operate in multiple locations. It includes an internal power source (250) for autonomous operation, wireless communication capabilities for system integration, and a motor (260) for self-repositioning, enabling it to function reliably wherever placed
Solution Approach 2:
The gate device is equipped with an internal power source (250) that enables autonomous operation without external power connections. The motor (260) allows the device to move itself to desired locations, and the wireless communication unit handles system integration automatically, reducing installation complexity
3Adaptability or versatility
If wireless communication technologies are used for movable user entry devices, then placement flexibility is enabled, but energy consumption increases
Solution Approach 1:
The wireless communication operates in periodic intervals rather than continuously. The gate device establishes wireless connections when needed for access control operations and remains in low-power states between communications, reducing overall energy consumption while maintaining placement flexibility
Solution Approach 2:
The system can dynamically adjust communication parameters such as transmission power and communication frequency based on operational needs and environmental conditions, optimizing energy consumption while maintaining reliable access control functionality
