Solution Overview

Problem

Current methods lack an efficient means for users to obtain information related to human-powered vehicles, such as components, specifications, and maintenance instructions, directly from images without requiring specialized diagnostic devices.

Innovation Solution

A detecting device equipped with a control unit that executes a machine learning model trained on human-powered vehicle data, allowing users to input images and receive identification information and confidence values for detected components, along with related information like specifications, installation methods, and recommendations, displayed as text or graphical data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a machine learning model is used to detect components from images, then information accessibility is improved, but device complexity increases

Engineering Contradiction:
Improveinformation accessibilityVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent uses an image as an intermediary between the user and the diagnostic system. Instead of requiring users to directly interact with complex diagnostic devices or provide detailed specifications, they simply capture an image of the component, which the system then processes to provide diagnostic information.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system creates a digital copy (image) of the physical component and uses this copy for analysis. The image serves as a surrogate that captures all necessary visual information about the component without requiring the actual physical component to be present or measured directly.

Inventive Principle:
Principle #26Copying

2Measurement precision

If specialized diagnostic devices are required for component identification, then measurement precision is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvecomponent identification accuracyVSAvoiduser accessibility
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The system performs self-service by automatically analyzing the captured image and identifying components without requiring user expertise or interaction with complex diagnostic tools. The machine learning model autonomously processes the image and provides diagnostic information.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces traditional mechanical or electronic diagnostic devices with an image-based system. Instead of using specialized tools to physically measure or identify components, the system uses visual capture and machine learning algorithms to achieve the same diagnostic function.

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

3Loss of information

If comprehensive component information is provided, then information completeness is improved, but information processing complexity increases

Engineering Contradiction:
Improveinformation completenessVSAvoiddata processing complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The system segments the information provision process by first identifying the specific component in the image, then retrieving and presenting only the relevant information for that component. This avoids overwhelming the user with all possible component information simultaneously.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary action by pre-processing and organizing component information in advance. When a component is identified in an image, the system can quickly retrieve and present the relevant pre-organized information without requiring complex real-time processing.

Inventive Principle:
Principle #10Preliminary action
