Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the system processes all packetized audio signals, then complete audio communication is achieved, but network bandwidth and processor capacity are wasted due to excessive transmissions

Engineering Contradiction:
Improveaudio signal processing throughputVSAvoidnetwork bandwidth utilization
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The patent applies preliminary action by performing authentication and characteristic analysis of audio signals before allowing them to proceed through the full processing pipeline. The security appliance analyzes audio characteristics and sets alarm conditions in advance, filtering out malicious or excessive transmissions before they consume substantial network bandwidth and processor resources, thus resolving the contradiction between processing completeness and resource efficiency

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the system authenticates all packetized audio signals, then security against malicious transmissions is improved, but processing time and computational resources increase

Engineering Contradiction:
Improveauthentication accuracyVSAvoidsignal processing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies local quality by implementing selective authentication based on alarm conditions and characteristic analysis. Rather than uniformly processing all signals with the same level of scrutiny, the system applies different processing depths to different signals - performing detailed authentication only when alarm conditions are triggered or characteristics indicate potential threats. This resolves the contradiction by maintaining high security for suspicious signals while allowing rapid processing of normal signals

Inventive Principle:
Principle #3Local quality

3Object-affected harmful factors

If the system terminates communication sessions based on alarm conditions, then malicious transmissions are blocked, but legitimate communications may be interrupted

Engineering Contradiction:
Improvemalicious transmission blockingVSAvoidlegitimate communication continuity
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent applies feedback by implementing a monitoring and adjustment mechanism where the system continuously analyzes audio signal characteristics and alarm conditions, then adjusts session termination decisions based on this feedback. The content selector component receives alarm condition indications and makes informed decisions about whether to terminate sessions, allowing the system to learn from patterns and reduce false positives while maintaining blocking effectiveness against actual threats

Inventive Principle:
Principle #23Feedback

AI summary

The present disclosure is generally directed a data processing system for authenticating packetized audio signals in a voice activated computer network environment. The data processing system can improve the efficiency and effectiveness of auditory data packet transmission over one or more computer networks by, for example, disabling malicious transmissions prior to their transmission across the network. The present solution can also improve computational efficiency by disabling remote computer processes possibly affected by or caused by the malicious audio signal transmissions. By disabling the transmission of malicious audio signals, the system can reduce bandwidth utilization by not transmitting the data packets carrying the malicious audio signal across the networks.
