Wearable Maintenance Assistant Hands-Free Component Location
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Maintenance personnel face difficulties in performing complex tasks as they often need both hands to consult drawings and manuals, making it hard to locate and identify components in systems.
Innovation Solution
A maintenance assistance system using tags placed on systems, a processor, camera, speaker, and input system integrated into wearable devices like safety glasses or gloves, which helps technicians locate components by analyzing camera data and providing instructions through speech, allowing hands-free operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If maintenance personnel consult detailed drawings and manuals to locate components and confirm maintenance steps, then accuracy of maintenance task is improved, but both hands are occupied making it difficult to perform maintenance tasks
Solution Approach 1:
The system segments information delivery by providing component location guidance first, then maintenance step instructions separately. The wearable device divides the maintenance process into distinct phases: navigation to component location, then execution of maintenance procedures, allowing hands-free operation at each stage
Solution Approach 2:
The wearable computing device acts as an intermediary between the maintenance personnel and the maintenance information. Instead of requiring direct interaction with physical drawings and manuals, the system mediates information delivery through audio instructions and visual displays on the wearable device, freeing both hands for maintenance work
2Reliability
If detailed drawings and manuals are consulted during maintenance, then proper maintenance steps are confirmed, but time required to perform maintenance task increases
Solution Approach 1:
The system performs preliminary actions by pre-loading maintenance procedures and component location data into the wearable device before the maintenance task begins. The maintenance personnel receive step-by-step instructions in real-time without needing to search through physical manuals, as the information is already prepared and available on the device
Solution Approach 2:
The system replaces the mechanical interaction with physical drawings and manuals (flipping pages, searching physically) with an electronic information delivery system. The wearable device provides instant access to maintenance procedures through audio and visual interfaces, eliminating the time-consuming physical search process while maintaining information accuracy
3Loss of information
If traditional maintenance assistance methods are used, then component location can be identified, but complexity of maintenance operation increases
Solution Approach 1:
The wearable device serves multiple functions: it provides component location guidance, delivers maintenance step instructions, and offers hands-free operation capability. This universal device replaces multiple separate tools (drawings, manuals, search equipment) with a single integrated system, reducing operational complexity while maintaining information delivery effectiveness
