Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a centralized architecture is used to monitor and notify communication devices of reception condition modifications, then the system can centrally manage reception conditions, but latency problems occur when informing multiple devices

Engineering Contradiction:

Improvecentralized management of reception conditionsVSAvoidlatency in informing communication devices

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent extracts the centralized monitoring function and removes it from the system. Instead of a central authority managing reception conditions, each communication device independently monitors and detects modifications itself, eliminating the latency inherent in centralized notification systems while maintaining reliable reception condition management through distributed autonomy

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Each communication device performs self-monitoring of reception conditions without requiring centralized control. The devices independently detect modifications, determine when others will detect them, and autonomously adjust operating modes, transforming the system from centralized management to self-service distributed intelligence

Inventive Principle:

Principle #25Self-service

2Loss of time

If each communication device independently detects reception condition modifications, then latency is reduced, but synchronization between devices becomes challenging

Engineering Contradiction:

Improvereduced latency in detectionVSAvoidsynchronization between devices

Core Design Contradiction:

Loss of timeVSStability of the object's composition

Solution Approach 1:

Each device performs preliminary calculation of the detection instant for other devices based on known transmission timing information. By pre-determining when other devices will detect the same modification, the system enables synchronized response without requiring real-time coordination, thus maintaining stability while reducing latency

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system establishes feedback mechanisms where devices exchange timing information and detection status. This feedback loop allows devices to adjust their operating modes at synchronized instants based on their predictions of when others will detect modifications, maintaining system stability through coordinated autonomous action

Inventive Principle:

Principle #23Feedback

AI summary

The invention relates to a method of determining the instant of consideration of a modification of at least one reception condition for signals in a communication system comprising at least two communication devices. The method comprises the steps, executed by a communication device, of detecting (E702) at least one modification of the reception conditions for signals in the communication system, determining (E703) the instant at which at least one other communication device will have detected the modification of the reception conditions for the signals, and establishing (E704) an operating mode of the first communication device as a function of the instant determined. The invention also relates to an associated determining device.
