Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There are difficulties and inconveniences in accessing and utilizing maintenance information for construction equipment during performance tests and maintenance, leading to increased downtime and costs due to the need for expert on-site dispatch.
Innovation Solution
A method and device utilizing augmented reality to provide a maintenance manual for construction machines, where a virtual 3D model of the machine is displayed on a device, and maintenance manual information is overlaid on the model in response to user input, allowing for easy access and intuitive understanding of maintenance procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If expert on-site dispatch is used for maintenance, then diagnostic accuracy is improved, but loss of time and economic cost increase
Solution Approach 1:
The maintenance manual system enables operators to perform self-diagnosis and self-maintenance using augmented reality guidance, eliminating the need for expert dispatch. The system provides step-by-step visual instructions that allow non-experts to carry out maintenance tasks independently, reducing both downtime and costs while maintaining adequate diagnostic capability.
Solution Approach 2:
The augmented reality maintenance manual acts as an intermediary between expert knowledge and operators. It captures and transmits expert diagnostic procedures and maintenance knowledge through visual AR guidance, making expert-level information accessible to non-experts without requiring physical expert presence.
2Reliability
If expert on-site dispatch is used for maintenance, then diagnostic accuracy is improved, but maintenance cost increases
Solution Approach 1:
The system enables operators to perform maintenance tasks independently using AR-guided instructions, eliminating the need to dispatch expensive expert resources. This self-service capability maintains diagnostic accuracy through structured guidance while dramatically reducing maintenance costs by removing the need for expert travel and on-site presence.
Solution Approach 2:
The maintenance manual system creates digital copies of expert knowledge and procedures, storing them in an accessible format that can be retrieved and followed by any operator. This copying of expert expertise into a reusable digital format eliminates the need to repeatedly dispatch experts for similar tasks.
3Loss of information
If traditional maintenance manual access is used, then information availability is improved, but ease of operation worsens
Solution Approach 1:
The system transitions from traditional 2D manual pages to 3D augmented reality visualizations. Maintenance information is overlaid directly onto the equipment in the operator's field of view, providing spatial context and eliminating the need to physically search through manuals or interpret flat diagrams without real-world reference.
Solution Approach 2:
The AR device serves as an intermediary that delivers maintenance information directly to the operator's visual field. Instead of requiring the operator to actively search through physical or digital manuals, the system passively presents relevant information in context, significantly improving accessibility and ease of use.
