Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If users manually take surveys or capture images to check user status, then the system can obtain some information, but the user must spend independent time and effort, and the information amount and diversity are insufficient

Engineering Contradiction:
Improveinformation diversity and accuracyVSAvoiduser time for status check
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The system automatically captures images through the door camera and analyzes them using AI models without requiring user intervention. The door camera continuously monitors and the processor automatically infers user characteristics such as physical condition, body shape, and body size, eliminating the need for users to manually take surveys or capture images.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical actions (user taking surveys, manually capturing images) with an automated AI-based system. The AI model processes images automatically to infer user characteristics, substituting the mechanical process of manual data collection with an automated intelligent system.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If the system manually collects user status information through surveys, then the process is simple to implement, but the information obtained is limited in amount and diversity, making accurate information provision difficult

Engineering Contradiction:
Improveinformation diversityVSAvoidsystem complexity for information collection
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The door camera serves multiple functions: it not only monitors door entry/exit but also automatically captures images for AI analysis to infer various user characteristics including physical condition, body shape, and body size. This multi-functional approach increases information diversity without adding separate collection systems.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system changes the parameter of information collection from manual survey responses to automated image analysis. By analyzing visual data through AI models, the system can infer multiple characteristics simultaneously, transforming the type of data collected to achieve greater diversity and accuracy.

Inventive Principle:
Principle #35Parameter changes

3Measurement precision

If the system uses AI model analysis of door images, then accurate and diverse user characteristic information can be obtained automatically, but the device complexity increases

Engineering Contradiction:
Improveaccuracy of user characteristic inferenceVSAvoidcomplexity of AI analysis system
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines the door camera function with AI image analysis and user characteristic inference into an integrated system. The processor simultaneously performs image capture, AI model analysis, and characteristic inference, merging multiple functions to achieve accurate information provision while managing system complexity through integration.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

One embodiment of the present disclosure provides an artificial intelligence (AI) assistance device based on door image analysis. The device comprises: an image reception unit for receiving an image captured by a camera attached to a door, the image including an image of a person entering or exiting through the door; and a processor, which uses a storage place for storing the received image and an AI model, so as to analyze the image stored in the storage, and thus infers the characteristics of the entering or exiting person and provides information corresponding to the inferred characteristics.
