Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple service agents are allowed to serve the same shared communication medium, then service coverage and versatility are improved, but association accuracy and billing reliability deteriorate

Engineering Contradiction:
Improveservice coverageVSAvoidassociation accuracy
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent segments the shared communication medium into multiple distinct signal propagation paths, each characterized by unique attenuation profiles. Service agents are associated with specific paths, allowing multiple agents to serve the medium simultaneously while maintaining accurate client-agent associations through path-specific measurements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by measuring signal attenuation specifically along the propagation path between each service agent and client. This localized measurement approach enables accurate association determination for each agent-client pair independently, even when multiple agents serve the same shared medium.

Inventive Principle:
Principle #3Local quality

2Measurement precision

If signal attenuation measurements are used to determine association, then association accuracy is improved, but measurement complexity and device complexity increase

Engineering Contradiction:
Improveassociation accuracyVSAvoidmeasurement complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent implements self-service by having service agents autonomously perform signal attenuation measurements and independently determine their association status with clients. This eliminates the need for complex centralized measurement coordination, reducing overall system complexity while maintaining high measurement precision.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent uses feedback mechanisms where service agents continuously measure signal attenuation and adjust their association decisions based on the measured values. This feedback loop enables accurate association determination through relatively simple iterative measurements rather than complex one-time measurements.

Inventive Principle:
Principle #23Feedback

3Duration of action of stationary object

If handoff mechanisms are implemented for switching between service agents, then service continuity is improved, but system complexity and association determination difficulty increase

Engineering Contradiction:
Improveservice continuityVSAvoidsystem complexity
Core Design Contradiction:
Duration of action of stationary objectVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by having service agents continuously monitor signal attenuation before handoff is needed. This allows the system to proactively identify the optimal service agent for each client, simplifying the handoff process and reducing the complexity of real-time association determination during service transitions.

Inventive Principle:
Principle #10Preliminary action

AI summary

Associating service agents in communication over a network to one or more respective clients coupled to the network at respective ports of the network is described. At a first service agent, a first signal is received from a first client coupled to the network at a first port. The first signal propagates over a first signal propagation path between the first service agent and the first port. An association between the first service agent and the first client is established based at least in part on a difference between: the first signal propagation path between the first service agent and the first port, and a second signal propagation path between the first service agent and a second port or between a second service agent and the first port.
