Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If converged device is introduced into IMS to provide large-screen, high-definition multimedia communication, then multimedia communication capability is improved, but user satisfaction deteriorates when communication connection quality is poor

Engineering Contradiction:
Improvemultimedia communication capabilityVSAvoiduser satisfaction
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements dynamic adaptation of media interface parameters based on real-time network quality detection. The communication terminal adjusts media description information including code rate, resolution, and format according to detected network conditions, allowing the system to transition between high-definition and standard-definition modes dynamically. This resolves the contradiction by making the system adaptable to varying network conditions while maintaining reliable user experience.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes physical parameters of the media stream such as code rate, resolution, and format based on network quality. When network quality deteriorates, the system reduces code rate and resolution to ensure smooth transmission. This parameter adaptation allows the converged device to maintain multimedia communication capability across different network conditions while preserving user satisfaction.

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If media stream transmission uses high definition settings, then multimedia communication quality is improved, but transmission reliability deteriorates under poor network conditions

Engineering Contradiction:
Improvemultimedia communication qualityVSAvoidtransmission reliability
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The system dynamically adjusts media stream parameters including code rate and resolution based on real-time network quality detection. The communication terminal continuously monitors network conditions and adapts the media interface parameters accordingly, switching between high-definition and standard-definition transmission modes. This dynamic adjustment ensures transmission reliability is maintained while preserving multimedia communication quality as much as possible under current network conditions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements parameter changes in the media stream by adjusting code rate, resolution, and format based on network quality thresholds. When network quality falls below certain thresholds, the system reduces code rate and resolution to ensure reliable transmission. This parameter adaptation resolves the contradiction between maintaining high definition quality and ensuring transmission reliability under varying network conditions.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If new media interface is established frequently to adapt to network changes, then user experience is improved, but system complexity increases

Engineering Contradiction:
Improveuser experienceVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent implements preliminary action by pre-defining multiple media description information sets with different parameter configurations (high definition, standard definition, low bandwidth modes). The communication terminal detects network quality and selects the appropriate pre-configured media interface without requiring complex real-time parameter optimization. This approach improves user experience through rapid adaptation while reducing system complexity by using pre-prepared configurations rather than complex real-time adjustments.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms where the communication terminal continuously monitors network quality and compares it against predefined thresholds. Based on this feedback, the system automatically selects and switches between different media interface configurations. This feedback-driven approach simplifies the control logic by using threshold-based decision making rather than complex optimization algorithms, thereby improving user experience while managing system complexity.

Inventive Principle:
