Solution Overview

Problem

Existing wireless devices with multiple client modules face high power consumption and communication bandwidth issues due to independent connections for notifications, particularly critical for IoT devices.

Innovation Solution

Implement a notification client device in the wireless device to receive notifications from a notification service device via an optimized protocol, centralizing the notification process and waking up client modules only when necessary.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If each client module maintains independent connections to service providers for notifications, then notification reliability is improved, but power consumption and communication bandwidth increase

Engineering Contradiction:

Improvenotification reliabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent merges multiple independent notification connections into a single shared connection between the wireless device and the notification service device. The notification service device sends notifications to the wireless device, which then distributes them to the appropriate client modules. This consolidation reduces the number of active connections from multiple to one, directly lowering power consumption and communication bandwidth requirements while maintaining notification reliability through the centralized service device.

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If each client module maintains independent connections to service providers for notifications, then notification reliability is improved, but communication bandwidth increases

Engineering Contradiction:

Improvenotification reliabilityVSAvoidcommunication bandwidth

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent consolidates multiple notification communication channels into a single shared communication path. Instead of each client module having its own dedicated connection to service providers, all notifications pass through a single connection between the wireless device and the notification service device. This reduces the total communication bandwidth required while maintaining reliable notification delivery through the centralized service architecture.

Inventive Principle:

Principle #5Merging (Combining)

3Speed

If client modules continuously monitor for notifications, then notification responsiveness is improved, but power consumption increases

Engineering Contradiction:

Improvenotification responsivenessVSAvoidpower consumption

Core Design Contradiction:

SpeedVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic action by having the notification service device send notifications at appropriate intervals rather than requiring continuous monitoring. The wireless device receives notifications periodically from the service device and distributes them to client modules only when needed. This periodic notification mechanism maintains responsiveness while significantly reducing power consumption compared to continuous monitoring approaches.

Inventive Principle:

Principle #19Periodic action

4Adaptability or versatility

If multiple independent notification connections are established, then notification coverage is improved, but device complexity increases

Engineering Contradiction:

Improvenotification coverageVSAvoidconnection management complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary - the notification service device - that mediates between multiple client modules and their respective service providers. This intermediary handles the complexity of managing multiple connections and notification routing, allowing the wireless device to maintain broad notification coverage without increasing its own complexity. The service device acts as a mediator that consolidates connection management while preserving adaptability and versatility across different client modules.

Inventive Principle:

Principle #24Intermediary (Mediator)
