Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If DSL connection bandwidth is reduced to save power, then energy consumption is reduced, but synchronization time increases when bandwidth needs to be enhanced again

Engineering Contradiction:

Improveenergy consumptionVSAvoidsynchronization time

Core Design Contradiction:

Use of energy by moving objectVSLoss of time

Solution Approach 1:

The system performs preliminary actions by proactively adjusting DSL connection parameters before actual service requirements arise. It analyzes historical service data to predict future bandwidth needs and pre-configures appropriate connection profiles, thereby avoiding time-consuming synchronization when bandwidth enhancement is actually needed.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements dynamic bandwidth adjustment by continuously monitoring service usage patterns and automatically transitioning between different connection profiles. This dynamic approach allows the DSL connection to adapt its bandwidth and power consumption in real-time based on actual service demands, rather than using static configurations.

Inventive Principle:

Principle #15Dynamics

2Loss of time

If DSL connection is kept in high-power state to avoid synchronization delays, then synchronization time is reduced, but energy consumption increases

Engineering Contradiction:

Improvesynchronization timeVSAvoidenergy consumption

Core Design Contradiction:

Loss of timeVSUse of energy by moving object

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system enables self-service by automatically managing DSL connection profiles without manual intervention. It autonomously monitors service usage, predicts bandwidth requirements, selects appropriate profiles, and executes parameter adjustments, thereby eliminating the need for user involvement while optimizing both energy consumption and synchronization performance.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If multiple DSL connection profiles are maintained for different service scenarios, then adaptability to service requirements is improved, but device complexity increases

Engineering Contradiction:

Improveadaptability to service requirementsVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system implements multi-functionality by using a single DSL connection interface that can dynamically switch between multiple pre-defined connection profiles. Each profile represents a different service scenario (e.g., voice-only, data-intensive, video streaming), allowing the system to provide diverse service adaptations without requiring separate physical connections or complex reconfiguration mechanisms.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system achieves adaptability through parameter changes by modifying DSL connection parameters (such as bandwidth allocation, modulation schemes, and power levels) based on the selected profile. This allows flexible adaptation to different service requirements by changing operational parameters rather than altering the fundamental connection structure, thereby managing complexity effectively.

Inventive Principle:

Principle #35Parameter changes

AI summary

The invention suggests method of generating and handling of DSL connection-profiles thereby providing an adaptation functionality of a DSL-connection, wherein each time a service is requested by a user of a DSL-connection, individual service-based-data are collected and analyzed. Then, a current individual DSL-connection profile comprising individual repetition times and an individual mean transmit data rate is assigned to this service-based-data and compared with any individual DSL-connection profile already stored in an operations scheduling memory. Depending on the result of the step of comparing, an already stored individual DSL-connection profile is updated based on the current individual DSL-connection profile or the current individual DSL-connection profile is stored as a further individual DSL-connection profile, wherein prior to each time of repetition of any stored individual DSL-connection profile, a start time of correspondingly adjusting the condition of the DSL-connection is set to respectively match a respective imminent stored individual DSL-connection profile.
