Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If configuration parameters are fixed by default, then device complexity is reduced, but adaptability to different network policies deteriorates

Engineering Contradiction:

Improveconfiguration management complexityVSAvoidadaptability to network policies

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic configuration parameters that can be adjusted based on network policies. The wireless device receives configuration parameters from the network node that are adapted to specific network policies, allowing the device to transition from static default configurations to dynamic, policy-driven configurations. This resolves the contradiction by making the configuration system flexible and adaptive without requiring complex manual intervention.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent enables the wireless device to automatically receive and apply configuration parameters from the network node without requiring manual configuration. The device autonomously handles configuration updates by receiving indication messages containing configuration parameters adapted to network policies, thereby reducing configuration management complexity while maintaining high adaptability.

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If configuration parameters are manually configured, then adaptability to network policies is improved, but ease of operation deteriorates

Engineering Contradiction:

Improveadaptability to network policiesVSAvoidconfiguration operation ease

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent implements automatic configuration where the wireless device autonomously receives configuration parameters from the network node through indication messages. This eliminates the need for manual configuration operations while maintaining adaptability to network policies, as the network node automatically provides policy-adapted configuration parameters to the device.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent establishes a feedback mechanism where the network node monitors network policies and automatically adjusts configuration parameters accordingly. The node sends indication messages to the wireless device with updated configuration parameters when policy changes occur, ensuring continuous adaptability without manual intervention and maintaining ease of operation.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If configuration parameters are not standardized, then adaptability to different networks is improved, but device complexity increases

Engineering Contradiction:

Improvenetwork compatibilityVSAvoidconfiguration handling complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal configuration mechanism using standardized indication messages that can carry configuration parameters adapted to different network policies. The wireless device and network node use a common message format defined in the patent that works across different network types and policies, providing universal compatibility without increasing device complexity through standardization.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A method performed by a wireless device (130) for handling configuration of the wireless device (130). The wireless device (130) operates in a communications network (10). The wireless device (130) sends (203) an indication to a network node (110) operating in the communications network (10). The indication comprises a configuration object in Constrained Application Protocol (CoAP). The configuration object comprises one or more configuration parameters of the wireless device (130) in the communications network (10). The wireless device (130) then receives (204) another indication from the network node (110). The another indication comprises a first instruction to configure the wireless device (130) to use at least one changed configuration parameter of the one or more configuration parameters. The at least one changed configuration parameter id adapted to one or more policies of the communications network (10) for the wireless device (130).
