Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional remote cameras are used to capture images of advertisements, then advertisement display verification is enabled, but equipment cost increases and human verification is required

Engineering Contradiction:

Improveadvertisement verification reliabilityVSAvoidequipment complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces mechanical camera-based verification systems with electromagnetic field-based sensing systems. Sensors detect electromagnetic emissions from display devices to verify advertisement content, eliminating the need for physical cameras and human verification while maintaining reliability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-service verification by having display devices automatically transmit operational data and advertisement content through electromagnetic signals. Sensors passively receive this data without requiring human intervention, allowing the system to verify itself autonomously

Inventive Principle:

Principle #25Self-service

2Ease of operation

If cameras are used for remote verification, then advertisement monitoring is possible, but security and privacy concerns arise in secured facilities

Engineering Contradiction:

Improveremote verification capabilityVSAvoidsecurity privacy concerns

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces electromagnetic field sensors as an intermediary between the verification system and the display device. These sensors detect electromagnetic emissions without requiring visual access or physical proximity, enabling remote verification while respecting security boundaries in secured facilities

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

Visual camera-based monitoring is replaced with electromagnetic sensing that can penetrate physical barriers. This substitution allows verification in environments where cameras are prohibited, as electromagnetic sensors can detect signals through walls and secure barriers without compromising privacy or security

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If human verification is used for advertisement display, then accurate content confirmation is achieved, but time consumption and cost increase

Engineering Contradiction:

Improvecontent verification accuracyVSAvoidverification time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system implements automated feedback loops where sensors continuously monitor electromagnetic signals from display devices, compare received advertisement data against expected content, and immediately identify discrepancies. This real-time feedback mechanism maintains verification accuracy while eliminating time-consuming human review

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The verification system performs self-validation by automatically comparing received electromagnetic signal data with expected advertisement content. The system identifies and flags discrepancies without human intervention, achieving both high accuracy and rapid processing

Inventive Principle:

Principle #25Self-service

AI summary

A system for monitoring displayed content, such as advertisements, has at least one sensor that is used to monitor an electronic display and provide information about the operation of the display, such as the content being displayed or whether one or more components of the display are operating correctly. The sensor is selected, positioned, and/or otherwise configured to limit the its ability to collect information in the environment surrounding the display so as to reduce concerns about the use of the sensor in a private or secure environment. The system may be used to confirm that the hardware of the display system is operating correctly and displaying the proper content at the proper times.
