Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If devices use multiple communication protocols for service provision, then adaptability and service compatibility are improved, but device complexity and protocol selection overhead increase

Engineering Contradiction:
Improveservice compatibilityVSAvoidprotocol selection overhead
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by having devices exchange connection capability information before establishing actual connections. Devices pre-advertise their supported protocols and capabilities, allowing other devices to select appropriate protocols in advance without trial-and-error connection attempts. This reduces protocol selection overhead during runtime while maintaining multi-protocol adaptability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary mechanism through connection capability exchange messages that mediate between multiple protocols. These messages serve as a standardized interface that allows devices to discover and negotiate protocol compatibility without directly implementing complex multi-protocol logic, thereby reducing device complexity while preserving service compatibility.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If devices establish connections through trial-and-error protocol attempts, then protocol compatibility can be achieved, but connection time and network efficiency deteriorate

Engineering Contradiction:
Improveprotocol compatibilityVSAvoidconnection time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent eliminates trial-and-error connection attempts by implementing preliminary protocol capability exchange. Devices advertise their supported protocols and services before connection establishment, enabling the initiating device to select a compatible protocol in advance. This ensures protocol compatibility is achieved without time-consuming connection attempts and failures.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If devices exchange detailed capability information before connection, then connection optimization is improved, but message overhead and processing load increase

Engineering Contradiction:
Improveconnection efficiencyVSAvoidmessage overhead
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The patent extracts only the essential connection capability information needed for protocol selection and service matching, omitting unnecessary detailed capabilities. The connection capability exchange messages contain focused data about supported protocols and basic service types, reducing message overhead while still enabling efficient connection optimization through informed protocol selection.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

Methods and apparatuses are disclosed for communicating in a wireless communication network. One method of communicating over a wireless communication network includes transmitting, by a first wireless device, a connection capability request message to a second wireless device requesting connection capability information of the second wireless device. The method further includes receiving, by the first wireless device, a connection capability response from the second wireless device indicating one or more communication protocols available for providing a service to the first wireless device. In some aspects, the method may further include selecting, by the first wireless device, based at least in part on the connection capability response, a communication protocol from one of the one or more communication protocols indicated, wherein the communication protocol may be utilized for obtaining the service from the second wireless device.
