Solution Overview

Problem

Existing wireless communication systems are not proactive in providing targeted advertisements to Wi-Fi devices, and they struggle to distribute advertisements in a single format due to the proliferation of various Wi-Fi devices with different media requirements, limiting the effectiveness of information delivery.

Innovation Solution

A system and method that monitor Wi-Fi access points and devices to determine supported media types, transmitting location-specific advertisements in compatible formats, and generating billing reports, while also tracking device movement to send relevant information such as traffic warnings and alerts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If advertisements are transmitted to multiple types of Wi-Fi devices, then market reach is improved, but device complexity increases due to supporting multiple media formats

Engineering Contradiction:
Improvecompatibility with different Wi-Fi devicesVSAvoidsystem complexity for format conversion
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system performs preliminary actions by determining the media file types supported by each Wi-Fi device before transmitting advertisements. The server identifies device capabilities in advance and prepares appropriate advertisement formats proactively, avoiding the need for complex real-time format conversion and reducing system complexity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system changes parameters by adapting advertisement format parameters to match the specific media file type supported by each Wi-Fi device. By modifying the advertisement format based on device capabilities (e.g., image format, video format, audio format), the system achieves broad compatibility without requiring complex multi-format support infrastructure.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If location-specific advertisements are transmitted proactively, then user experience is improved, but information delivery accuracy must be maintained

Engineering Contradiction:
Improveproactive information deliveryVSAvoidlocation accuracy for targeting
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The system uses feedback by monitoring the movement of Wi-Fi devices within the network and using this information to determine when to transmit location-specific advertisements. By continuously tracking device location and using this feedback to trigger targeted advertisement delivery, the system achieves both proactive information delivery and accurate location-based targeting.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If device movement is tracked to send relevant information, then user engagement is improved, but system resources are consumed

Engineering Contradiction:
Improvetargeted information deliveryVSAvoidnetwork resources for tracking
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The system applies partial action by monitoring device movement only to the extent necessary for triggering location-specific advertisements. Rather than continuously tracking and analyzing all movement data, the system uses movement monitoring selectively to determine when a device enters a relevant geographic area for advertisement delivery, reducing resource consumption while maintaining targeted delivery capability.

Inventive Principle:
Principle #16Partial or excessive action
