Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing 3D modeling software is controlled using keyboard or mouse input devices, then modeling precision can be maintained, but ease of operation deteriorates in touch screen environments
Solution Approach 1:
The patent replaces traditional mechanical input devices (keyboard and mouse) with a touch screen interface that responds to finger gestures. The touch screen detects touch coordinates directly from user contact, eliminating the need for separate mechanical input devices and enabling intuitive direct manipulation of 3D models through tactile interaction.
Solution Approach 2:
The patent introduces a touch screen as an intermediary between the user and the 3D modeling system. The touch screen serves as both the display medium and the input device, mediating user interactions by converting finger touches into digital signals that control modeling operations, thereby bridging the gap between human touch and computer processing.
2Adaptability or versatility
If 3D modeling is performed at heritage building reconstruction sites using traditional equipment, then modeling accuracy can be maintained, but adaptability to field environments deteriorates
Solution Approach 1:
The patent makes the 3D modeling system universal by enabling it to operate across multiple environments - both traditional office settings and field reconstruction sites. The system adapts to different locations by accepting touch screen input, which works equally well in portable field devices and stationary workstations, thereby eliminating environmental constraints on modeling operations.
Solution Approach 2:
The patent introduces dynamic adaptability by allowing the modeling system to adjust to different operational environments. The touch screen interface dynamically responds to user inputs regardless of location, and the system can switch between various modeling modes and data sources (such as integrating with 3D scanning data) based on the specific field conditions and requirements.
3Ease of operation
If measured drawings with member information are displayed on touch screen, then ease of operation improves, but device complexity increases
Solution Approach 1:
The patent merges multiple functions into the touch screen interface - displaying measured drawings, accepting user input, providing visual feedback, and controlling modeling operations all through a single touch screen interaction system. This consolidation eliminates the need for separate input devices and simplifies the overall system architecture despite the increased computational requirements.

AI summary
An apparatus and method for modeling a cultural heritage building, which may intuitively model a 3D digital cultural heritage building while exhibiting the characteristics of the 3D digital cultural heritage building, through the use of a touch screen UI on a smart mobile device in a place where it is difficult to use a PC or existing software. The disclosed apparatus includes a measured drawing arrangement unit for displaying, on a touch screen, measured drawings that include information about members constituting a cultural heritage building, a member model generation unit for performing modeling based on multiple points input via the touch screen, thus generating 3D member models, a database for storing the member models generated by the member model generation unit, and a member arrangement unit for arranging each of the stored member models at an original location thereof based on the measured drawings.
