Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual positioning and connecting of building elements is used in CAD/CAE systems, then flexibility and control in placement are improved, but time consumption and error probability increase significantly
Solution Approach 1:
The system performs preliminary actions by automatically generating space bodies from architectural models and pre-defining placement rules based on gap analysis before actual element placement. This preliminary processing enables rapid automated placement while maintaining design flexibility, resolving the contradiction between manual control and time efficiency.
Solution Approach 2:
The patent introduces space bodies and gap analysis as intermediary structures that mediate between the architectural model and building element placement. These intermediaries automatically generate placement rules that preserve design intent while enabling high-speed automated placement, thus reducing time consumption without sacrificing operational flexibility.
2Adaptability or versatility
If manual positioning and connecting of building elements is used, then adaptability to design changes is improved, but error probability and sensitivity to model changes increase
Solution Approach 1:
The system implements feedback mechanisms where gap analysis continuously monitors spatial relationships and automatically adjusts placement rules when architectural models change. This feedback loop maintains reliability by detecting and correcting potential errors while preserving adaptability to design modifications through automated rule regeneration.
Solution Approach 2:
The patent dynamically changes parameters of placement rules based on gap characteristics and architectural model modifications. When design changes occur, the system automatically updates gap analysis results and regenerates placement rules, maintaining reliability through parameter adaptation while enabling versatility in responding to different design scenarios.
3Productivity
If automated placement systems are used to reduce time consumption, then productivity is improved, but complexity of the placement system increases
Solution Approach 1:
The patent segments the automated placement system into distinct functional modules: space body generation, gap analysis, placement rule generation, and element placement execution. This segmentation enables high productivity through automated processing while managing complexity by organizing functions into independent, manageable components that can be developed and maintained separately.
4Manufacturing precision
If comprehensive gap analysis and face classification are performed to improve placement accuracy, then manufacturing precision is improved, but computational complexity increases
Solution Approach 1:
The patent applies local quality by performing detailed gap analysis and face classification only at specific critical locations where building elements will be placed, rather than uniformly across the entire model. This approach achieves high placement accuracy at placement sites while reducing overall computational complexity by focusing detailed analysis only where needed.
