Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If network switching is performed by switching between different SIMs and network interfaces, then network connectivity can be maintained across different service providers, but communication interruptions occur causing dropped calls and loss of data streaming capability

Engineering Contradiction:

Improvenetwork connectivityVSAvoidcommunication continuity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system establishes a bonded interface between multiple network interfaces before switching is needed. This preliminary configuration ensures that when network switching occurs, the communication channel remains intact because the bonded interface is already in place to handle the transition seamlessly.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Multiple network interfaces are merged into a single bonded interface that combines their capabilities. This merging allows the system to maintain communication continuity by aggregating multiple network connections, so that when switching between SIMs or networks, the bonded interface ensures uninterrupted data flow and prevents dropped calls.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If multiple network interfaces are used to maintain connectivity across different networks, then network versatility is improved, but system complexity increases

Engineering Contradiction:

Improvenetwork compatibilityVSAvoidinterface management

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The bonded interface acts as an intermediary layer between multiple network interfaces and the communication system. This intermediary abstracts the complexity of managing multiple interfaces, providing a unified interface that simplifies control while maintaining compatibility across different networks and service providers.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If network switching is performed to maintain communication across different service providers, then service coverage is improved, but data streaming capability is reduced or lost during switching

Engineering Contradiction:

Improveservice coverageVSAvoiddata streaming capability

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The bonded interface maintains continuous data flow across network switches by keeping the interface configuration active and ready. This ensures that data streaming operations continue uninterrupted during network switching, as the bonded interface preserves the communication channel while allowing the underlying network connections to change.

Inventive Principle:

Principle #20Continuity of useful action
