Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for providing services to mobile devices, such as advertisement services and QR code-based information retrieval, face challenges in real-time relevance and efficiency, leading to increased power consumption and user inconvenience due to frequent scanning and data processing.

Innovation Solution

A system comprising a user terminal, a service terminal, and a server that uses short-range wireless communication to broadcast user ID and context information, allowing for real-time service information provision without manual user intervention, thereby reducing power consumption and improving service delivery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If short-range communication is used to provide service information, then user convenience is improved by eliminating QR code scanning, but power consumption increases due to frequent signal checking and data scanning

Engineering Contradiction:

Improveuser convenienceVSAvoidpower consumption

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The user terminal performs signal checking and data scanning periodically rather than continuously. The controller checks for signals at predetermined intervals and only activates the scanning function when a signal is detected, reducing unnecessary power consumption while maintaining service delivery capability

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The service terminal broadcasts service information in advance before the user terminal needs it. This allows the user terminal to receive and process information proactively rather than continuously searching, reducing the frequency of active scanning operations and associated power consumption

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If multiple users use short-range communication simultaneously, then service coverage is improved, but the number of scanning operations and data processing increases, leading to higher power consumption

Engineering Contradiction:

Improveservice coverageVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

A server acts as an intermediary between the service terminal and user terminal. The server receives service information from the service terminal, processes it, and delivers it to the user terminal. This intermediary role reduces the direct communication burden on the user terminal, allowing multiple users to be served efficiently without each terminal performing extensive scanning and processing operations

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system checks for multiple user signals periodically rather than continuously monitoring all users. When signals are detected, the system processes the data in batches, reducing the total number of scanning operations required to serve multiple users simultaneously

Inventive Principle:

Principle #19Periodic action
