Innovation Solution
A method for implementing a dual-purpose GIS network using legacy mobile electronic devices, such as cellular telephones, by uploading a GIS data collector application and data dictionary, allowing these devices to collect and forward geo-spatial data without the need for extensive training or dedicated PCs, and enabling data collection in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated GIS data collectors are deployed, then data collection capability is improved, but cost and device complexity increase significantly
Solution Approach 1:
The patent applies universality by enabling mobile electronic devices to perform both their original functions and GIS data collection functions. The mobile device is configured with a GIS data collector application that allows it to collect, store, and transmit geographic data, thereby serving multiple purposes with a single device and eliminating the need for dedicated specialized equipment.
Solution Approach 2:
The patent implements copying by transferring the GIS data collection functionality from dedicated specialized devices to common mobile devices. The GIS data collector application replicates the essential data collection capabilities on devices that users already possess, making the technology accessible without requiring expensive specialized hardware.
2Measurement precision
If dedicated GIS data collectors are used, then data collection precision is improved, but ease of operation deteriorates due to complicated interfaces
Solution Approach 1:
The mobile device leverages its existing familiar interface and user experience to perform GIS data collection. Users interact with the GIS application through the same intuitive touchscreen and navigation methods they use for other mobile applications, eliminating the need to learn complex specialized interfaces while maintaining accurate data collection capabilities.
3Power
If dedicated PCs are deployed for each data collector, then data processing capability is improved, but loss of time increases due to download bottlenecks
Solution Approach 1:
The patent implements continuous data transmission by enabling mobile devices to automatically forward collected geographic data to remote servers in real-time as data is collected. This eliminates the batch processing model where data must be manually downloaded at the end of each session, allowing uninterrupted data flow and eliminating bottlenecks associated with simultaneous downloads by multiple users.
Solution Approach 2:
The patent introduces a wireless communication network as an intermediary between the mobile data collection devices and the central processing system. This intermediary enables direct cloud-based data upload and storage, eliminating the need for physical connection to dedicated PCs and allowing asynchronous data transmission that avoids bottlenecks.
4Reliability
If specialized training is provided for GIS data collectors, then operator skill level is improved, but loss of time increases due to training requirements
Solution Approach 1:
The patent copies the user interface and interaction patterns from familiar mobile applications to the GIS data collection function. This familiarization copying allows users to immediately understand and operate the GIS application without specialized training, as they are already proficient with the device's basic operations and interface conventions.
