Solution Overview

Problem

Existing information distribution management systems struggle to optimize advertisement distribution based on the number of unique users, leading to inefficient selection of distribution surfaces.

Innovation Solution

An information distribution management device that generates heat maps indicating the necessity of information distribution, estimates the number of unique users, and evaluates the distribution effect based on these metrics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If advertisement distribution is managed based on total number of views, then the distribution coverage is improved, but the unique user measurement accuracy deteriorates

Engineering Contradiction:
Improvedistribution coverageVSAvoidunique user measurement accuracy
Core Design Contradiction:
Quantity of substanceVSMeasurement precision

Solution Approach 1:

The patent segments the measurement of advertisement distribution into two distinct metrics: total number of views (for distribution coverage) and number of unique users (for measurement accuracy). By separating these measurements, the system can accurately evaluate advertisement effectiveness based on unique users while maintaining awareness of overall distribution coverage, resolving the contradiction between these two requirements.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If distribution surfaces are selected without considering unique users, then the distribution process is simplified, but the advertisement effectiveness evaluation deteriorates

Engineering Contradiction:
Improvedistribution process simplicityVSAvoidadvertisement effectiveness evaluation
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent introduces a feedback mechanism where the number of unique users is measured and used to evaluate advertisement effectiveness. This feedback loop allows the system to automatically adjust distribution strategies based on actual unique user engagement, improving evaluation reliability while maintaining operational simplicity through automated processing.

Inventive Principle:
Principle #23Feedback

3Quantity of substance

If the same advertisement is distributed to multiple information display devices, then the distribution coverage is improved, but the duplicate viewing increases

Engineering Contradiction:
Improvedistribution coverageVSAvoidduplicate viewing
Core Design Contradiction:
Quantity of substanceVSObject-generated harmful factors

Solution Approach 1:

The patent applies local quality by measuring and evaluating the number of unique users for each specific information display device. This allows the system to identify which devices are reaching unique users and which are causing duplicate views, enabling differentiated treatment of each display device based on its actual unique user engagement characteristics.

Inventive Principle:
Principle #3Local quality
