Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual recording methods are used for inspection data, then device complexity is reduced, but productivity and reliability deteriorate due to input errors and inefficiency
Solution Approach 1:
The terminal device automatically captures inspection data through its camera and position measurement units, eliminating the need for manual recording. The device serves itself by autonomously recording inspection information, position data, and images without requiring operator intervention for data entry, thereby improving productivity while keeping the system simple.
Solution Approach 2:
The patent replaces manual mechanical recording processes with an automated electronic system. The terminal device uses a camera to capture images and a position measurement unit to automatically record location data, substituting the mechanical act of handwritten recording with automated optical and electronic measurement systems.
2Loss of information
If inspection records are not linked with design information, then system complexity is reduced, but loss of information increases due to inability to correlate field data with configuration data
Solution Approach 1:
The management device acts as an intermediary between the terminal device and the design information database. It receives inspection data from the terminal device, associates it with relevant design information from the database using position matching, and manages the linked records. This intermediary approach enables information linkage without requiring direct complex integration between all system components.
Solution Approach 2:
The system creates a digital copy of the inspection record that includes embedded position information and associated design data. By copying and storing the relationship between inspection data and design information in the database, the system enables information retrieval and correlation without requiring the physical or structural integration of the original data sources.
3Productivity
If real-time position measurement and display are implemented, then productivity is improved through efficient navigation, but device complexity increases due to additional measurement and communication units
Solution Approach 1:
The terminal device integrates multiple functions into a single unit: it serves as a camera for image capture, a position measurement unit for location tracking, a display device for showing inspection information and navigation guidance, and a communication device for data transmission. This multi-functionality improves productivity by consolidating tools while managing complexity through integration rather than proliferation of separate devices.

AI summary
A field cooperation system according to an embodiment includes a terminal device and a management device. The terminal device includes: a position measurement unit; and a display unit. The position measurement unit measures a position of the terminal device. A display device displays a display image. The management device includes: a database; and a display control unit. The database stores three-dimensional data representing a layout of a structure. The display control unit generates a display image to illustrate the structure and an icon representing the position of the terminal device on the display unit in correspondence with each other based on the three-dimensional data and the measured position of the terminal device.
