Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If an endpoint device is to support multiple wireless communication protocols and standards, then the device's functionality and adaptability are improved, but the device complexity increases due to requiring multiple transceivers and protocol stacks

Engineering Contradiction:
Improveprotocol compatibilityVSAvoidtransceiver quantity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal transceiver architecture where a single transceiver can operate across multiple frequency bands and support multiple wireless protocols (Wi-Fi, Bluetooth, Zigbee, etc.) through configurable radio resource allocation. The network processor dynamically configures the transceiver's operational parameters to match the required protocol, eliminating the need for separate dedicated transceivers for each protocol while maintaining full protocol compatibility

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If radio resources are allocated dynamically to support multiple protocols, then the system's versatility is improved, but the scheduling complexity and processing overhead increase

Engineering Contradiction:
Improveresource allocation flexibilityVSAvoidscheduling complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent employs dynamic parameter adjustment where the network processor modifies transceiver operational parameters (frequency, bandwidth, modulation scheme, power level) based on real-time protocol requirements and network conditions. This parameter-based configuration approach allows flexible resource allocation across multiple protocols while using standardized control mechanisms, thereby managing scheduling complexity through systematic parameter management rather than complex protocol-specific scheduling logic

Inventive Principle:
Principle #35Parameter changes

3Device complexity

If a single transceiver is used for multiple protocols, then device complexity is reduced, but the risk of radio resource conflicts and interference increases

Engineering Contradiction:
Improvetransceiver quantityVSAvoidradio resource conflict
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The patent implements a feedback-based radio resource management system where the network processor continuously monitors transceiver operational status, channel conditions, and protocol performance metrics. Based on this feedback, the system dynamically adjusts resource allocation, frequency selection, and power levels to prevent conflicts and interference between simultaneous or sequential protocol operations, ensuring reliable multi-protocol communication through closed-loop control

Inventive Principle:
Principle #23Feedback

AI summary

It is provided a method for enabling configuring an endpoint device. The method comprises: receiving a network access request, the network access request comprising a parameter request comprising a reference to a storage server for obtaining one or more device parameters; obtaining the device parameters from the storage server; providing the parameter request to a local bootstrap server that is on the same local network as the network access server; receiving a command from the local bootstrap server to configure the local network such that traffic on the local network to a remote bootstrap server, being external to the local network, is directed to the local bootstrap server; configuring the local network such that traffic on the local network to the remote bootstrap server, being external to the local network, is directed to the local bootstrap server; and providing a network resource allocation message to the endpoint device.
