Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If network-based service usage measurement systems are used, then service provider capacity is increased, but service provider costs increase and profits decrease

Engineering Contradiction:

Improvenetwork capacity utilizationVSAvoidservice provider costs

Core Design Contradiction:

ProductivityVSLoss of energy

Solution Approach 1:

The patent implements device-assisted service usage measurement where the user device itself performs service usage measurement and CDR generation. The service processor in the device measures service usage parameters (data volume, time, location) and creates CDRs locally, eliminating the need for extensive network-based measurement infrastructure. This self-service approach reduces network capacity requirements and service provider costs while maintaining accurate billing capabilities.

Inventive Principle:

Principle #25Self-service

2Measurement precision

If network-based CDR generation is used, then service usage can be measured, but the system cannot be tailored to diverse device types and user experiences

Engineering Contradiction:

Improveservice usage measurementVSAvoiddevice type flexibility

Core Design Contradiction:

Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic CDR generation where the service processor in the device adapts measurement parameters and CDR creation based on device type, service plan, and user experience requirements. The system can dynamically adjust what is measured (data volume, time, location) and how CDRs are formatted based on the specific device capabilities and service agreements, enabling tailoring to diverse device types while maintaining measurement precision.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent enables local customization of service usage measurement at the device level. Different devices can have different measurement configurations, CDR formats, and reporting requirements based on their specific capabilities and service plans. The service processor locally determines the appropriate measurement parameters and CDR structure, allowing each device type to be optimized for its specific requirements while maintaining network-wide billing consistency.

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If device-assisted service usage measurement is implemented, then service plans can be tailored to user needs, but device complexity increases

Engineering Contradiction:

Improveservice plan customizationVSAvoidservice processor complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal service processor architecture that can handle multiple service plan types and device configurations through a single integrated component. The service processor is designed to be multi-functional, supporting various measurement parameters, CDR formats, and service plan configurations within a single device component, thereby reducing overall device complexity while enabling extensive service plan customization.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent enables service plan customization through parameter changes rather than structural modifications. The service processor can adjust measurement parameters, CDR generation parameters, and reporting parameters based on the service plan configuration, allowing diverse service plans to be implemented through software parameters rather than hardware complexity.

Inventive Principle:

Principle #35Parameter changes
