Solution Overview

Problem

Existing pet status assessment systems fail to easily recognize the status of pets in image data, such as their emotions and actions, making it difficult for users to understand their conditions.

Innovation Solution

A pet status assessment system that includes an area detector, information generator, and assessor to analyze image data, using learned models to detect specific areas of pets and generate posture information, allowing for the assessment of emotions and actions based on this information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional image detection methods are used to identify pets in images, then basic detection capability is achieved, but the system cannot accurately recognize pet status including emotions and actions

Engineering Contradiction:
Improvepet status recognition accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system segments the pet recognition task into distinct components: area detection (locating the pet), posture information extraction (analyzing body position), and status assessment (determining emotions and actions). This segmentation allows each component to be optimized independently, improving overall accuracy without proportionally increasing complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary action by pre-defining multiple posture types and status categories before actual image analysis. The posture information generator is pre-configured with knowledge of different pet postures, enabling it to quickly map detected areas to meaningful status categories without requiring complex real-time reasoning.

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If detailed posture information is extracted using learned models, then pet status assessment accuracy is improved, but processing time and computational resources increase

Engineering Contradiction:
Improveposture detection accuracyVSAvoidprocessing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system applies partial action by focusing computational resources only on the most relevant posture features needed for status assessment. Rather than analyzing every possible image characteristic, the posture information generator extracts only the specific posture elements necessary for determining emotions and actions, reducing processing time while maintaining accuracy.

Inventive Principle:
Principle #16Partial or excessive action

3Loss of information

If the system provides comprehensive pet status information including emotions and actions, then user understanding of pet conditions is improved, but the complexity of information presentation increases

Engineering Contradiction:
Improveinformation completenessVSAvoiduser interface simplicity
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The system applies local quality by presenting different levels of information detail in different interface locations or contexts. Comprehensive status information including emotions and actions is provided, but the presentation is localized and organized such that users can access detailed information when needed while maintaining a simple overall interface structure.

Inventive Principle:
Principle #3Local quality

AI summary

A pet status assessment system includes an area detector, an information generator, and an assessor. The area detector detects, in image data, a specific area representing at least a part of appearance of a pet as a subject. The information generator generates pet information. The pet information includes posture information which is based on a learned model and the image data. The learned model has been generated by learning the posture of the pet to recognize, on an image, the posture of the pet. The assessor assesses, based on the pet information, a pet status concerning at least one of an emotion of the pet or an action of the pet.
