Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual parapet design operations are performed, then design flexibility and adaptability are maintained, but design time increases and accuracy decreases due to operator-dependent variations
Solution Approach 1:
The system enables self-service by automatically extracting wall geometric information and generating parapet designs without requiring manual input for each parameter. The automated parameter extraction and generation process eliminates operator-dependent variations while maintaining design accuracy, directly resolving the contradiction between precision and time loss.
Solution Approach 2:
The patent replaces manual mechanical design operations with an automated computational system. The system automatically extracts geometric parameters from BIM models and generates parapet designs through algorithmic processing, substituting human manual operations with automated mechanisms that provide consistent accuracy without time loss.
2Adaptability or versatility
If manual parapet generation is performed, then design customization is possible, but repetitive operations are required with each design change
Solution Approach 1:
The system implements dynamics by enabling real-time adaptation to design changes through automated parameter extraction and generation. When design modifications are needed, the system dynamically updates the parapet design by re-extracting wall parameters and regenerating the parapet automatically, maintaining customization capability while eliminating repetitive manual operations and improving productivity.
Solution Approach 2:
The patent utilizes parameter changes by automatically extracting geometric parameters from the BIM model and using them to generate parapet designs. When design customization is required, the system modifies parameters such as wall height, position, and dimensions, automatically regenerating the parapet to reflect these changes, thus maintaining adaptability while improving design efficiency through automation.
3Productivity
If automated parapet generation is implemented, then design efficiency and accuracy are improved, but system complexity increases
Solution Approach 1:
The system achieves universality by integrating multiple functions into a single automated parapet generation system. The system can extract various geometric parameters from BIM models, support different wall configurations, and generate multiple parapet types automatically, providing multi-functionality that improves design efficiency while managing system complexity through unified automation.
Solution Approach 2:
The patent introduces an intermediary layer between the BIM model and the parapet design output. This intermediary system automatically extracts geometric parameters from the BIM model and translates them into parapet design parameters, serving as a mediator that simplifies the interaction between existing BIM data and new design requirements, thereby improving efficiency while managing complexity through structured parameter transformation.
