Solution Overview
Problem
Conventional surveying machines face challenges in accurately and quickly identifying the causes of measurement errors due to improper use, aging, environmental factors, and machine failures, making it difficult for manufacturers to diagnose issues remotely and reproduce failure conditions.
Innovation Solution
A communication system for surveying devices that includes a self-maintenance check aid function, troubleshooting aid function, and questionnaire creation aid function, enabling users to perform self-diagnosis and transmit data to a main server for analysis, allowing for remote identification of issues and efficient troubleshooting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional surveying machines are used without remote diagnostic capabilities, then the device complexity remains low, but the time required to identify and resolve measurement errors increases significantly
Solution Approach 1:
The surveying machine automatically collects and stores operation status information, error logs, and environmental data before any problem occurs. This preliminary data collection enables rapid remote diagnosis when measurement errors occur, eliminating the need for time-consuming on-site troubleshooting while the machine is in use.
Solution Approach 2:
A communication unit acts as an intermediary between the surveying machine and the external network, transmitting diagnostic data to remote servers or manufacturers. This intermediary enables remote analysis of measurement errors without requiring physical access to the machine, significantly reducing diagnostic time while keeping the on-site device complexity manageable.
2Productivity
If manufacturers wait for machines to be sent for inspection or receive inquiries, then the device complexity remains simple, but the productivity of error resolution decreases
Solution Approach 1:
The system establishes a feedback loop where operation status information and error data are automatically transmitted to the external network, which then provides diagnostic results and solutions back to the user. This continuous feedback enables rapid problem resolution without requiring the machine to be physically returned to the manufacturer, dramatically improving productivity.
Solution Approach 2:
The surveying machine performs self-diagnosis by automatically collecting and transmitting its own operation data and error logs. This self-service capability eliminates the need for immediate manufacturer intervention or complex on-site troubleshooting, enabling quick identification and resolution of issues while maintaining simple device architecture.
3Measurement precision
If error logs are generated and read locally, then the device complexity is minimal, but the measurement precision of problem identification deteriorates
Solution Approach 1:
The system transitions from two-dimensional local error log analysis to three-dimensional remote comprehensive analysis by transmitting multiple types of data (operation status, error logs, environmental conditions) to external servers. This dimensional expansion enables much more accurate identification of problem causes by analyzing data in conjunction with other factors, while keeping the on-site device complexity low.
