Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If passive, semi-passive, and semi-active terminals use ultra-low power consumption and energy harvesting, then power consumption is reduced, but communication reliability deteriorates
Solution Approach 1:
The patent introduces an access network device as an intermediary that assigns target reader roles to terminal devices. This mediator coordinates communication between terminals and the network, ensuring reliable data transmission while allowing terminals to operate in low-power modes. The access network device manages the complexity of role assignment and communication protocols, shielding terminals from these complexities and enabling them to maintain ultra-low power consumption without sacrificing communication reliability.
2Device complexity
If terminal devices execute reader roles autonomously, then device complexity is reduced, but communication reliability deteriorates
Solution Approach 1:
The access network device serves as an intermediary that determines and assigns target reader roles to terminal devices based on communication requirements. This centralizes the complexity of role management in the network device rather than requiring complex autonomous decision-making at the terminal level. The terminal device simply executes the assigned role, reducing its complexity while the network device ensures communication reliability through intelligent role assignment and coordination.
Solution Approach 2:
The patent implements dynamic role assignment where the access network device determines target reader roles based on current communication requirements and terminal capabilities. This dynamic adjustment allows the system to optimize communication reliability in real-time while keeping terminal devices simple. The terminal device transitions between different reader roles (full reader, assisted reader, carrier-assisted reader) based on network decisions rather than autonomous complexity.
