Visual Inspection Guidance for DVIR Asset Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Daily Vehicle Inspection Reports (DVIRs) and electronic DVIR solutions rely on text-only descriptions for asset zones, leading to inefficiencies and potential missed defects due to differences in vehicle types, models, and non-standard inspection procedures, resulting in lost time and potential falsification of inspection durations.
Innovation Solution
Integrating visual and audio representations of vehicles and inspection zones within the DVIR application, allowing drivers to see the location of zones and components, tracking their proximity, and enforcing minimum inspection time thresholds to ensure accurate and thorough inspections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If text-only descriptions are used for asset zones, then the system complexity is low, but the inspection time increases and accuracy decreases
Solution Approach 1:
The patent creates visual copies (photographs or graphical representations) of the actual asset zones and components. These visual copies are displayed on the inspection device to guide the inspector in locating and identifying inspection zones, replacing the need for text-only descriptions and significantly reducing inspection time while maintaining system simplicity.
2Measurement precision
If visual representations are integrated into DVIR application, then inspection accuracy increases, but device complexity increases
Solution Approach 1:
The patent introduces an intermediary layer - a visual guide system that sits between the inspector and the physical asset. This intermediary provides photographs or graphical representations that map to physical zones, enhancing inspection accuracy without requiring complex modifications to the underlying DVIR system architecture.
Solution Approach 2:
The patent adds a visual dimension to the traditionally text-based DVIR system. By incorporating photographs or graphical representations as an additional layer of information, the system enhances inspection accuracy without fundamentally redesigning the entire application structure.
3Reliability
If driver proximity is tracked in real-time, then inspection quality improves, but energy consumption increases
Solution Approach 1:
The patent implements periodic tracking of driver proximity to the asset rather than continuous monitoring. The system checks the inspector's location at intervals or at key transition points between zones, ensuring inspection quality through location verification while minimizing energy consumption by activating sensors only when needed.
4Reliability
If minimum inspection time thresholds are enforced, then falsification is prevented, but inspection productivity decreases
Solution Approach 1:
The patent implements a feedback mechanism that monitors inspection duration and provides real-time feedback to the inspector. When the minimum time threshold is approached or exceeded, the system notifies the inspector, allowing them to adjust their pace. This prevents falsification through enforced minimum times while maintaining productivity by providing guidance rather than rigid constraints.
Data Source
AI summary
An operator's proximity to an automotive vehicle being inspected is tracked and recorded. An audio and/or a visual representation of the automotive vehicle being inspected, inspection zones, and components within the inspection zones are rendered. A representation of the automotive vehicle being inspected is updated to reflect a condition of the vehicle being inspected, a condition of the inspection zones, and the numbers of defects for each of inspection zones. The audio and visual representations shown as part of any defects of the vehicle being inspected may be recorded. During a vehicle inspection, a visual indication of a driver's location in proximity to a visual representation of the automotive vehicle being inspected may be displayed.
