Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional device provisioning techniques use back-end servers to manage device profiles, then centralized control and security are improved, but network resource consumption and system complexity increase

Engineering Contradiction:

Improvecentralized controlVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the device provisioning management function from the back-end server infrastructure and relocates it to a local wireless device. This eliminates the need for complex server queries and external network resources, reducing system complexity while maintaining provisioning capabilities through local storage and management of device profiles

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent implements self-service by enabling wireless devices to autonomously provision and manage their own profiles without requiring external server intervention. Devices can store, retrieve, and update their own provisioning information locally, reducing dependency on complex back-end infrastructure while maintaining centralized security policies through local enforcement

Inventive Principle:

Principle #25Self-service

2Reliability

If conventional device provisioning techniques query back-end servers, then centralized security management is improved, but network resource overhead and provisioning time increase

Engineering Contradiction:

Improvesecurity managementVSAvoidprovisioning time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-storing device profiles and provisioning information locally in wireless devices before they are needed. This eliminates the need for real-time server queries during provisioning operations, reducing provisioning time while maintaining security through pre-configured authentication credentials and policies

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Devices perform self-service provisioning by autonomously accessing their stored profile information locally without requiring external server communication. This eliminates network delays and server query overhead, reducing provisioning time while maintaining security through local enforcement of pre-configured security policies

Inventive Principle:

Principle #25Self-service

3Reliability

If conventional device provisioning uses external server infrastructure, then centralized control is improved, but network resource consumption increases

Engineering Contradiction:

Improvecentralized controlVSAvoidnetwork resource consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent extracts provisioning management functions from external server infrastructure and relocates them to local wireless devices. This eliminates the need for continuous network communication with back-end servers, reducing network resource consumption and energy usage while maintaining centralized control through locally stored security policies

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Wireless devices perform self-service provisioning by autonomously managing their own profiles using local storage and processing resources. This eliminates the need for energy-consuming server queries and external network communication, reducing network resource consumption while maintaining centralized security through local policy enforcement

Inventive Principle:

Principle #25Self-service

AI summary

Systems, methods, and devices provide device provisioning of wireless devices in wireless environments. Methods include determining, at a central wireless device, angle of arrival information associated with a first transceiver of the central wireless device and a first wireless connection with a peripheral wireless device, generating wireless profile data for a second wireless connection with the peripheral wireless device, and transmitting the wireless profile data via the first wireless connection to the peripheral wireless device to configure the second wireless connection of the peripheral wireless device.
