Solution Overview

Problem

Existing short-range wireless communication technologies for electronic devices rely on the Internet for notification message transmission, leading to inflexibility and a risk of user privacy disclosure.

Innovation Solution

Implementing an application-based short-range notification method using Bluetooth, NFC, WLAN, ZigBee, or UWB technologies to transmit identifiers of applications and scenarios directly between devices, eliminating the need for an Internet connection and additional servers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If Internet-based notification transmission is used, then notification messages can be sent between electronic devices, but flexibility is poor and user privacy is at risk

Engineering Contradiction:

ImproveflexibilityVSAvoidprivacy disclosure risk

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the essential notification function from the Internet-dependent system and implements it using only short-range wireless communication. The notification message transmission is separated from Internet infrastructure, allowing devices to communicate directly via Bluetooth, NFC, or other short-range technologies, thereby eliminating privacy risks associated with Internet transmission while maintaining notification capability

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces an intermediary server that facilitates notification transmission without requiring Internet connectivity between the electronic devices. The server acts as a mediator that receives notification requests and relays them through short-range wireless communication, enabling flexible notification delivery while protecting user privacy by avoiding direct Internet exposure of personal data

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If Internet-based notification transmission is used, then notification messages can be sent between electronic devices, but additional servers are required increasing costs

Engineering Contradiction:

Improvenotification transmissionVSAvoidserver configuration

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent enables electronic devices to perform notification transmission independently using built-in short-range wireless communication capabilities. Devices self-organize the communication链路 through direct pairing or proximity-based connection, eliminating the need for additional external servers and reducing system complexity while maintaining reliable notification delivery

Inventive Principle:

Principle #25Self-service

3Object-affected harmful factors

If short-range wireless communication is used without Internet, then privacy is protected and costs are reduced, but notification transmission capability must be maintained

Engineering Contradiction:

Improveprivacy disclosure riskVSAvoidnotification transmission efficiency

Core Design Contradiction:

Object-affected harmful factorsVSProductivity

Solution Approach 1:

The patent implements a universal notification system that works across multiple short-range wireless communication protocols (Bluetooth, NFC, WLAN, ZigBee, UWB). This multi-functional approach ensures that notification transmission can occur through any available short-range channel, maintaining high productivity and efficiency while protecting privacy by avoiding Internet dependency

Inventive Principle:

Principle #6Universality (Multi-functionality)
