Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex algorithm is used to select appropriate links for multi-link operation, then data transmission reliability is improved, but device complexity and hardware costs increase
Solution Approach 1:
The patent implements a feedback mechanism where the transmitter sends identical data packets through multiple links simultaneously and uses acknowledgment signals from the receiver to determine when to stop transmission. This simple feedback approach eliminates the need for complex link selection algorithms while maintaining high reliability through redundant transmission paths.
Solution Approach 2:
The patent segments the data transmission process by dividing data into identical copies that are transmitted through different links simultaneously. This segmentation allows each link to be treated independently with simple control logic, avoiding the need for complex centralized decision-making algorithms.
2Reliability
If a complex algorithm is used for link selection in multi-link operation, then data transmission reliability is improved, but transmission delays increase
Solution Approach 1:
The patent applies preliminary action by preparing multiple identical data packets in advance and transmitting them simultaneously through different links before any acknowledgment is received. This eliminates delays associated with complex real-time link selection algorithms and ensures continuous transmission without waiting for processing decisions.
Solution Approach 2:
The feedback mechanism allows the transmitter to stop transmission as soon as acknowledgment is received, eliminating unnecessary retransmissions and reducing overall transmission time while maintaining reliability through the simple stop-transmit condition rather than complex algorithmic decisions.
3Reliability
If identical data is transmitted through multiple links simultaneously, then data transmission reliability is improved, but retransmissions may occur if not properly controlled
Solution Approach 1:
The patent uses feedback signals from the receiver to control the transmitter's behavior. When acknowledgment is received, the transmitter stops transmission, preventing unnecessary retransmissions of identical data. This feedback-based control maintains transmission efficiency by avoiding redundant sends while ensuring reliability through the multi-link simultaneous transmission approach.
Solution Approach 2:
The transmission system dynamically adjusts its behavior based on real-time conditions by monitoring acknowledgment signals. The transmitter transitions from simultaneous multi-link transmission to stopped transmission state upon receiving acknowledgment, creating a dynamic control mechanism that optimizes both reliability and efficiency without fixed complex algorithms.
