Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If designers sketch various shapes one by one to explore ideas, then shape exploration is possible, but it is time-consuming and difficult to imagine changing shapes according to movements
Solution Approach 1:
The system performs preliminary action by automatically generating multiple shape variations based on movement constraints before the designer completes the sketching process. The shape prediction module pre-calculates possible shapes based on joint types and movement ranges, allowing designers to explore multiple shape options without manually sketching each one, thus reducing sketching time while maintaining shape exploration capability
Solution Approach 2:
The system uses copying by generating virtual copies of the product shape in different poses based on the initial sketch. Instead of requiring designers to redraw each shape variation, the system creates multiple copied instances with different configurations applied through the learned movement patterns, enabling rapid shape exploration without repeated manual sketching
2Measurement precision
If designers manually sketch each shape variation, then detailed shape exploration is possible, but the process becomes time-consuming and inefficient
Solution Approach 1:
The system replaces the mechanical sketching process with an automated computational system. Instead of manually sketching each shape variation, the deep learning model automatically generates shape predictions based on movement constraints and joint configurations, maintaining shape detail accuracy while dramatically improving design exploration efficiency by eliminating repetitive manual sketching
Solution Approach 2:
The system applies parameter changes by automatically adjusting shape parameters based on movement constraints and joint types. The model modifies geometric parameters such as joint angles, link lengths, and pose configurations to generate multiple shape variations, ensuring measurement precision is maintained while increasing productivity through automated parameter optimization rather than manual sketching
3Productivity
If the system generates multiple shape variations automatically, then productivity is improved, but the complexity of the system increases
Solution Approach 1:
The system achieves universality by creating a multi-functional platform that combines sketching, joint detection, shape prediction, and movement simulation in one integrated system. This universal design allows the same system to handle various product types and movement constraints, improving productivity across different design scenarios while managing complexity through consolidation rather than separate tools
Solution Approach 2:
The system uses an intermediary approach by introducing a deep learning model as a mediator between the designer's initial sketch and the final shape variations. This intermediary automatically processes the sketch, detects joints and movements, and generates shape predictions, thereby improving productivity while containing complexity within the automated processing layer rather than requiring complex user interactions

AI summary
Disclosed are an electronic device for carrying out three-dimensional sketching, an electronic device, and an operating method thereof. The disclosed electronic device comprises at least one processor which arranges a reference plane onto a three-dimensional virtual space including an object expressed by a plurality of lines, and generates a joint, which applies to a first part of the object, on the basis of repetitive movement of the first part overlapping with the reference plane, while a first touch input by a user on the reference plane is being maintained. The joint is determined according to the component type of the reference plane to which the first touch input is inputted, and the number of second touch inputs, of the user, for controlling the repetitive movement of the first part.
