Solution Overview

Problem

Existing location-based services using beacon technology face limitations in providing diverse services without increased power consumption, supporting various user equipment, and ensuring user privacy, as they either require separate applications, lead to high power usage, or result in unwanted spam services and privacy invasions.

Innovation Solution

A hybrid beacon scheme that combines forward and backward beacon schemes, allowing user equipment to switch between scanning and advertising modes based on beacon signal information, enabling efficient service provision without separate applications, reducing power consumption, and ensuring user consent and privacy protection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a forward beacon scheme is used where beacon devices transmit signals and user equipment scans them, then various location-based services can be provided, but power consumption increases and separate applications are required

Engineering Contradiction:

Improveservice diversityVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic mode switching between scanning mode and advertising mode based on service requirements. The user equipment can flexibly transition between these modes to balance service versatility and power consumption, rather than operating in a fixed scanning mode continuously

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system employs periodic beacon signal transmission in advertising mode instead of continuous scanning. This periodic action reduces power consumption by allowing the user equipment to enter low-power states between beacon transmissions while still providing location-based services

Inventive Principle:

Principle #19Periodic action

2Reliability

If user equipment continuously scans beacon signals to provide location-based services, then service coverage is maintained, but power consumption increases

Engineering Contradiction:

Improveservice availabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic beacon signal transmission instead of continuous scanning. The user equipment scans for beacons at periodic intervals rather than continuously, which maintains service availability while significantly reducing power consumption during idle periods

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system dynamically adjusts between scanning and advertising modes based on service needs. When services are actively required, scanning intensity increases; when services are not needed, the system transitions to lower-power advertising mode or idle state

Inventive Principle:

Principle #15Dynamics

3Speed

If beacon devices transmit location information continuously, then service reaction speed is improved, but power consumption increases

Engineering Contradiction:

Improveservice reaction speedVSAvoidpower consumption

Core Design Contradiction:

SpeedVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic beacon transmission with adjustable intervals. The system transmits beacon signals at periodic intervals rather than continuously, achieving a balance between service reaction speed and power consumption by optimizing the transmission period based on service requirements

Inventive Principle:

Principle #19Periodic action

4Area of stationary object

If user equipment transmits advertising signals in backward beacon scheme, then service coverage is expanded, but unwanted services and privacy invasions occur

Engineering Contradiction:

Improveservice coverageVSAvoidprivacy invasion

Core Design Contradiction:

Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The patent implements a feedback mechanism where the server manages user consent and service subscriptions. Before providing location-based services, the system receives feedback from the server confirming user consent, thereby preventing unwanted services and privacy invasions while maintaining expanded service coverage

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The server acts as an intermediary between the user equipment and service providers. It manages user consent information and service subscriptions, mediating the interaction to ensure that location-based services are only provided when users have given permission, thus protecting privacy while enabling service coverage expansion

Inventive Principle:

Principle #24Intermediary (Mediator)
