Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If voice-only smartphone users without WiFi access attempt to use internet-enabled applications, then application functionality is required, but internet connectivity is unavailable

Engineering Contradiction:

Improveapplication functionalityVSAvoidinternet connectivity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces a proxy gateway as an intermediary component that mediates between the voice-only smartphone and the internet. The gateway captures USSD messages from the smartphone, translates them into IP packets, and forwards them to the internet, enabling application functionality without direct internet connectivity on the smartphone.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the communication parameter from traditional internet protocols to USSD (Unstructured Supplementary Service Data) protocol. By encoding internet requests as USSD messages that can be transmitted over voice channels, the system enables data communication through a different parameter space that is accessible to voice-only smartphones.

Inventive Principle:

Principle #35Parameter changes

2Quantity of substance

If control information slots are used for their intended purpose, then control functionality is maintained, but data transmission capacity is reduced

Engineering Contradiction:

Improvedata transmission capacityVSAvoidcontrol functionality

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The patent applies partial action by utilizing only the unused portions of control information slots for data transmission. Instead of completely repurposing the slots, the system selectively uses available capacity within these slots to carry data, maintaining control functionality while extracting additional data transmission capability from existing resources.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

Apparatuses, methods, and systems for internet-enabled data for transparent application consumption over unstructured supplementary service data are disclosed. One method includes generating, by an application, IP (internet protocol) packets, encapsulating, by a proxy interface, the IP packets into protocol data units (PDUs), generating frames of data for facilitating communication through a wireless link, wherein the frames include data slots and control information slots, identifying, by the base station, unused control information slots of the frames of data, scheduling transmission of a stream of the PDUs over the unused control information slots for a full-time duration of the unused control information slots, inserting the PDUs into one or more of the scheduled control information slots of the frames of data as specified by the scheduling, and transmitting, by the computing device, the frames of data through the wireless link to the base station on the scheduled control information slots.
