Solution Overview

Problem

Existing Internet of Things (IoT) management systems require multiple subscription messages for a mobile phone to receive information from multiple IoT devices, leading to cumbersome and inefficient information notification processes.

Innovation Solution

An information notification method that determines a first resource feature and transmits a notification message only when the structure of resources satisfies this feature, eliminating the need for multiple subscription messages by creating a subscribed resource that indicates this feature.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the mobile phone transmits multiple subscription messages to subscribe to information of multiple devices, then the information notification function is achieved, but the information notification steps become cumbersome and efficiency decreases

Engineering Contradiction:
Improveinformation notification efficiencyVSAvoidinformation notification steps
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent merges multiple individual subscription messages into a single group subscription message. The mobile phone sends one group subscription message that includes identifiers of multiple target devices, and the server creates a group subscription relationship that consolidates notifications from all these devices. This combining approach reduces the number of communication steps and improves notification efficiency.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The group subscription message serves multiple functions simultaneously: it subscribes to information from multiple different devices in one message, creates a consolidated notification channel, and establishes a many-to-many relationship between the mobile phone and multiple IoT devices. This multi-functionality eliminates the need for separate subscription procedures for each device.

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

2Adaptability or versatility

If the mobile phone transmits multiple subscription messages to the Internet of Things management device, then information from multiple devices can be subscribed, but the number of messages increases leading to inefficient notification

Engineering Contradiction:
Improvesubscription coverageVSAvoidnotification time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

Multiple subscription requests are merged into a single group subscription message transmission. The mobile phone includes identifiers of multiple target devices within one message, and the server processes this single message to create subscription relationships with all specified devices simultaneously, reducing transmission time and processing overhead.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The mobile phone prepares a group subscription message in advance that contains all necessary device identifiers and subscription parameters before transmission. This preliminary preparation allows the server to immediately create multiple subscription relationships upon receiving the single message, eliminating sequential processing delays.

Inventive Principle:
Principle #10Preliminary action
