Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a wireless relay is used to extend network coverage, then the coverage area is expanded, but time delays in communications are introduced that are not recognized by network devices
Solution Approach 1:
The patent implements feedback by having the relay device transmit information about its relay operation to the network access point. This feedback mechanism enables the network to become aware of the relay's presence and the time delays it introduces, allowing for compensation measures to be taken while maintaining the coverage extension benefit
Solution Approach 2:
The patent applies parameter changes by adjusting communication parameters based on the relay operation information received from the relay device. The network access point modifies transmission parameters such as timing advance values to compensate for the time delays introduced by the relay, thereby resolving the contradiction between extended coverage and time delay
2Device complexity
If a wireless relay operates transparently, then device complexity is reduced, but relay-induced effects on communication paths are not accounted for
Solution Approach 1:
The patent introduces an intermediary mechanism where the relay device actively communicates operational information to the network access point. This intermediary information exchange allows the network to account for relay-induced effects without significantly increasing the complexity of the relay device itself, as the relay simply reports pre-determined operational parameters
3Productivity
If relay operation information is provided to the network, then communication path parameters can be optimized, but information loss occurs due to relay transparency
Solution Approach 1:
The patent applies preliminary action by having the relay device determine and report its operational information before actual communication occurs. This allows the network access point to pre-calculate and apply appropriate parameter adjustments, ensuring that communication efficiency is optimized from the outset rather than requiring reactive corrections
