Construction Site Ticketing for Unregistered Machine Position Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
At construction sites, it is impractical to register information on all work machines managed by various business operators, as operators frequently change, making it difficult to confirm the position information of all machines within a management system.
Innovation Solution
A management device and system that issues tickets associated with construction sites or groups, allowing communication terminals to acquire and output position information, enabling the display of multiple work machines' positions on a map regardless of their management status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all work machines are registered in the management system, then position information of all machines can be confirmed, but the system complexity and registration burden increase significantly
Solution Approach 1:
The patent introduces a ticket as an intermediary element that enables position information acquisition without direct system registration. The ticket contains identification information that allows work machines to be tracked through a simplified process, acting as a mediator between the management system and the work machines
Solution Approach 2:
The patent uses ticket information as a simplified copy or representation of work machine identification. Instead of registering complete machine profiles, the system uses ticket copies containing essential identification data to track position information
2Loss of information
If all work machines are registered in advance, then complete position tracking is achieved, but the registration process becomes impractical due to frequent operator changes
Solution Approach 1:
The patent performs preliminary action by issuing tickets to work machines before they arrive at the construction site. This allows position tracking to begin immediately upon arrival without requiring on-site registration, saving time when operators and machines are frequently changing
Solution Approach 2:
The ticket serves as a pre-prepared intermediary that carries identification information, eliminating the need for time-consuming registration processes when machines arrive at the site
3Device complexity
If work machines are not registered, then the management system remains simple, but position information of unregistered machines cannot be confirmed
Solution Approach 1:
The ticket acts as an intermediary that bridges the gap between unregistered machines and the management system. By using ticket information as a key, the system can acquire position information from unregistered machines without requiring full system registration
Solution Approach 2:
The ticket serves multiple functions: it identifies the work machine, enables position tracking, and works regardless of whether the machine is formally registered in the system. This universal approach allows both registered and unregistered machines to be tracked through the same mechanism

AI summary
A management device includes a ticket issuance unit that issues a ticket indicating work related to a construction site, a position information acquisition unit that acquires position information of a communication terminal acquiring the ticket, and an output unit that outputs the position information of the communication terminal selecting the ticket regarding the same construction site among the position information acquired by the position information acquisition unit.
