Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing systems struggle to accurately determine where and what kind of advertisements users are exposed to, both indoors and outdoors, which hinders targeted advertisement distribution and reduces advertising effectiveness.

Innovation Solution

An advertisement contact determination system and device that utilizes a communication unit to obtain device position information and a control unit to determine contact with Out Of Home (OOH) advertisements based on the user's traveling direction and proximity to certain apparatuses, associating device logs with apparatus logs to optimize advertisement contact determination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If contact information is collected through multiple channels (website forms, phone, email, social media), then the quantity of contact information increases, but the accuracy and reliability of contact information decreases due to incomplete or inaccurate data entry

Engineering Contradiction:

Improvequantity of contact informationVSAvoidaccuracy of contact information

Core Design Contradiction:

Quantity of substanceVSMeasurement precision

Solution Approach 1:

The system sends verification emails to collected contact information to verify accuracy. The verification email includes a verification code that the user must enter back to the system, creating a feedback loop that confirms the contact information is correct and active, thereby improving accuracy while maintaining the ability to collect from multiple channels

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system replaces manual verification methods with automated email-based verification. Instead of manually checking each contact entry, the system automatically sends verification emails and processes responses through electronic communication, improving both accuracy and efficiency of contact information collection

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If contact information is verified manually, then accuracy improves, but time consumption and labor costs increase

Engineering Contradiction:

Improveaccuracy of contact informationVSAvoidtime consumption for verification

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The verification process is made self-service by automatically sending verification emails to users and processing their responses automatically. Users perform the verification action themselves by receiving and responding to emails, eliminating the need for manual verification by the system operator and significantly reducing time consumption

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system replaces manual verification processes with automated electronic verification through email. The automated system sends verification codes, receives responses, and updates contact information without human intervention, dramatically reducing both time consumption and labor requirements while maintaining high accuracy

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Quantity of substance

If contact information is collected from multiple sources, then the volume of data increases, but the quality and reliability of the data decreases due to incomplete or inaccurate entries

Engineering Contradiction:

Improvevolume of contact dataVSAvoidreliability of contact data

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The system implements a feedback mechanism where verification emails are sent to all collected contact information regardless of source. This universal verification approach ensures that contact information from any channel (website forms, phone, email, social media) is subjected to the same accuracy check, maintaining high reliability while preserving the ability to collect from multiple sources

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The verification system is designed to work universally across all contact information sources and types. The same verification process applies whether contact data comes from website forms, phone entries, email submissions, or social media platforms, ensuring consistent quality control while maintaining the multi-channel collection capability

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

The present disclosure optimally determines a contact between a user and an advertisement. An advertisement contact determination system according to one aspect of the present disclosure includes a communication unit configured to obtain position information of a device, and a control unit configured to determine that a user of the device has come into contact with an Out Of Home (OOH) advertisement if the OOH advertisement is included in a certain range in a traveling direction of the user based on the position information of the device. The communication unit obtains a log of a certain apparatus, and the control unit determines whether the device exists in vicinity of the certain apparatus in a certain period of time or not and, if the device exists, associates the log of the certain apparatus in the certain period of time with the device.
