Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote recording and reporting systems for infrastructure assessments, such as roof inspections, are labor-intensive and prone to errors, requiring manual data entry that can lead to transcription mistakes and inaccuracies, and lack efficient methods to associate images with inspection data.
Innovation Solution
A system comprising a portable computing device with GPS, camera, and bidirectional communication, allowing on-site data collection, geographic positioning, and automatic association of images with inspection data, which is then transmitted to a central server for analysis and reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual data collection and recording methods are used during infrastructure inspections, then flexibility and adaptability in inspection procedures are maintained, but labor intensity increases and recording errors occur more frequently
Solution Approach 1:
The patent replaces manual mechanical data recording with an automated electronic system. Inspectors use a portable computing device with a standardized electronic form that automatically captures inspection data, eliminating manual transcription and reducing errors. The system substitutes human manual operations with automated electronic data collection and processing.
Solution Approach 2:
The system enables self-service through automated data capture features. The portable device automatically records inspector location via GPS, timestamps observations, and manages data storage without requiring manual intervention for these functions. This reduces the labor burden on inspectors while maintaining data accuracy.
2Loss of information
If images are taken separately from inspection data during roof assessment, then visual documentation of defects is achieved, but associating images with specific infrastructure components becomes difficult
Solution Approach 1:
The patent merges the image capture function with the inspection data collection system. The portable computing device integrates a camera that captures images directly within the inspection workflow, automatically linking each image to the specific infrastructure component and observation being documented. This eliminates the separation between visual documentation and data recording.
Solution Approach 2:
The portable computing device serves as an intermediary that bridges image capture and data association. The device's software automatically metadata tags each captured image with location data, timestamps, and component identifiers, serving as the mediator that connects visual evidence with inspection findings without requiring manual association efforts.
3Reliability
If hand-recorded inspection data is manually transcribed into spreadsheets or analysis software, then data can be processed for reporting, but opportunities for transcription errors and data inaccuracies increase
Solution Approach 1:
The patent replaces the mechanical process of manual transcription with automated electronic data capture and transfer. Inspection data is collected directly in digital format on the portable device and automatically transmitted to the central server, eliminating the intermediate manual transcription step that causes errors and delays.
Solution Approach 2:
The system performs preliminary data processing and validation at the point of collection. The portable device automatically formats data, validates entries against standardized fields, and prepares data for transmission before leaving the inspection site. This preliminary processing eliminates the need for later manual data entry and reduces errors.
4Reliability
If inspectors are not guided through required assessments, then inspection flexibility is maintained, but incorrect assessments and missing crucial information occur more often
Solution Approach 1:
The system implements feedback through the standardized electronic form that guides inspectors through required assessment steps. The form structure provides feedback by presenting a systematic sequence of inspection tasks, ensuring that all necessary components are evaluated. The automated system tracks completion and prompts for required information, maintaining reliability without significantly increasing operational complexity.

Data Source
AI summary
Systems and methods for recording and reporting data collected from a remote location are disclosed. A work order, defining infrastructure to be inspected at a remote site and including an inspection plan for collecting inspection information, is generated on a first computer system and transferred to a portable computing system. Inspection data is collected pursuant to the inspection plan on the portable computing system. A global positioning system (GPS) receiver associated with the portable computing system provides location information related to inspected infrastructure during the inspection. After collection, inspection data is transferred from the portable computing system to the first and/or to a second computing system for storage and the generation of related reports. The location information obtained during the inspection can be used to determine dimensional measurements of the infrastructure and to generate visual depictions of infrastructure components and defects.
