Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional predefined 3D models or static geometric primitives are used for geometric element generation, then the system has simple implementation, but the interaction efficiency and real-time adjustment capability are poor
Solution Approach 1:
The patent replaces traditional menu-based selection interfaces with gesture-based spatial curve drawing. Users draw curves directly in 3D space using hand gestures, and the system automatically generates geometric elements through algorithmic fitting. This substitutes mechanical interface navigation with natural gesture-based spatial interaction, dramatically improving interaction efficiency while maintaining manageable system complexity through automated processing.
Solution Approach 2:
The system performs automatic geometric element generation and parameter adjustment based on user-drawn curves. The geometric element fitting module automatically calculates position, orientation, scale, and other parameters without requiring manual configuration. This self-service approach allows the system to handle complex processing tasks autonomously, improving productivity while keeping the user interface simple.
2Loss of time
If predefined 3D models are selected from graphical menus, then the interface is simple, but tedious interface navigation and offline processing are required
Solution Approach 1:
The system performs geometric element fitting and parameter calculation in real-time as users draw curves, rather than requiring offline processing. The automatic generation process occurs immediately during the drawing action, eliminating delays between user input and result generation. This real-time processing significantly reduces the loss of time while maintaining ease of operation through natural gesture interaction.
3Adaptability or versatility
If spatial curve drawing based on hand posture detection is implemented, then real-time generation and dynamic adjustment capability is improved, but the device complexity and algorithm complexity increase
Solution Approach 1:
The patent introduces a geometric element fitting module as an intermediary between hand posture detection and geometric element generation. This module receives raw curve data from gesture recognition and automatically performs complex calculations for position, orientation, scale, and other parameters. By delegating complex algorithmic processing to this specialized intermediary component, the system achieves high adaptability and real-time adjustment capability while keeping the overall architecture manageable and modular.
4Productivity
If gesture-based spatial curve drawing is used, then intuitive interaction and creation efficiency are improved, but the requirement for real-time processing and gesture recognition accuracy increases
Solution Approach 1:
The system provides real-time visual feedback during gesture-based curve drawing, displaying the generated geometric elements as users draw. This immediate feedback allows users to adjust their gestures and see the impact on the generated elements, enabling iterative refinement. The feedback mechanism helps compensate for minor gesture recognition inaccuracies by allowing users to make small adjustments in real-time, maintaining high creation efficiency while managing the precision requirements through interactive correction.
