Solution Overview

Problem

Maintenance personnel face difficulties in performing complex tasks as they often need to consult detailed drawings and manuals with both hands, making it challenging to locate components and follow proper steps efficiently.

Innovation Solution

A maintenance assistance system utilizing a heads-up display with image processing to locate components by comparing camera images with stored images, overlaying instructions and tools on the display, and allowing voice or gesture input for guidance, enabling hands-free operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If maintenance personnel consult detailed drawings and manuals to locate components and confirm steps, then accuracy of maintenance tasks is improved, but ease of operation deteriorates due to needing both hands for consultation

Engineering Contradiction:
Improveaccuracy of component location and maintenance stepsVSAvoidease of performing maintenance tasks
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent replaces the mechanical system of manually consulting physical drawings and manuals with an optical/electronic system. A camera captures images of the work area, and a display device shows processed images with overlaid guidance information, allowing technicians to obtain accurate component location and procedure information without manually handling physical reference materials.

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

Solution Approach 2:

The patent introduces an intermediary system consisting of a camera, image processing unit, and display device. This intermediary captures the workspace, processes the visual information, and presents annotated guidance to the technician, serving as a mediator between the maintenance task and the required information without requiring direct manual consultation of reference materials.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If maintenance personnel manually locate components using drawings, then task completion is achieved, but productivity deteriorates due to time spent consulting references

Engineering Contradiction:
Improvereliability of task completionVSAvoidproductivity of maintenance tasks
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system performs preliminary actions by pre-processing and displaying guidance information before the technician needs it. The camera continuously captures the workspace, and the system pre-identifies components and prepares instructional overlays, so that when the technician looks at the display, the information is already ready and annotated, eliminating the need to stop and consult reference materials during the task.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces the manual mechanical process of searching through drawings and manuals with an automated optical and computational system that actively tracks the workspace, identifies components, and presents relevant information in real-time, significantly reducing the time required to locate components and understand maintenance steps.

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

3Ease of operation

If a heads-up display with image processing is implemented, then ease of operation and productivity are improved, but device complexity increases

Engineering Contradiction:
Improveease of hands-free maintenance operationVSAvoidcomplexity of maintenance assistance system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent implements a multi-functional system where a single integrated device performs multiple functions: the camera captures images, the processing unit identifies components and generates guidance information, and the display presents the annotated views. This universal system replaces multiple separate tools (drawings, manuals, physical references) with one cohesive device that handles visualization, information processing, and guidance delivery simultaneously.

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