Geocoded Ticket Entry for Excavation Site Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for identifying excavation sites underground facilities are often inaccurate due to reliance on verbal descriptions, leading to potential damage and safety issues during digging and construction operations.
Innovation Solution
A ticket entry system comprising a program management system, spatial management system, and data management system that allows users to geocode location designations, providing accurate and automated site location identification through map data visualization and geocoding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If verbal descriptions are used to identify excavation sites, then the ticket entry process is simple, but the location accuracy is poor
Solution Approach 1:
The patent introduces map data as an intermediary between the verbal description and the final location identification. The system displays map data corresponding to the search criteria and allows the user to visually identify and select the precise excavation site location on the map, thereby resolving the contradiction between simple entry process and accurate location identification
Solution Approach 2:
The patent transitions from one-dimensional verbal descriptions to two-dimensional visual map data. By displaying map data with spatial coordinates and allowing visual selection on the map interface, the system adds a spatial dimension to location identification, significantly improving accuracy while maintaining user-friendly operation
2Device complexity
If manual ticket entry is performed, then the system complexity is low, but the productivity is reduced
Solution Approach 1:
The system performs automatic geocoding of the search criteria and automatic retrieval of corresponding map data without requiring manual intervention. The locate ticket is automatically created with the identified site location, eliminating manual data entry steps and improving productivity while keeping the system architecture relatively simple
Solution Approach 2:
The system pre-geocodes the search criteria before displaying map data to the user. This preliminary processing of location data and automatic retrieval of map information reduces the time required during actual ticket entry, thereby improving productivity without significantly increasing system complexity
3Ease of operation
If verbal descriptions are used for site location, then the information collection is easy, but the information accuracy is insufficient
Solution Approach 1:
The system provides visual feedback by displaying map data corresponding to the search criteria and the identified site location. This visual confirmation allows users to verify that the correct location is selected, preventing information loss and ensuring accuracy while maintaining easy information collection through the interface

AI summary
A ticket entry system and method includes a program management system that receives contact information and a search criteria for a locate request. The program management system transmits the search criteria to a spatial management system that geocodes the search criteria and retrieves map data from a data management system corresponding to the search criteria geocode. The spatial management system transmits the map data to the program management system, which transmits the map data to a user interface. The user interface receives an indication of a site location where the operation is to be performed. The program management system transmits the site location indication to the spatial management system. The spatial management system geocodes the site location indication and transmits the site location geocode to the program management system. The program management system creates a locate ticket, which comprises the site location geocode and the contact information.
