Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If wind protection systems are added to buildings, then protection against wind forces is improved, but device complexity increases
Solution Approach 1:
The wind protection device is divided into multiple lateral face elements (130) that can be independently positioned at different locations on the building. Each face element creates its own riser shaft, allowing the system to be scaled and configured based on specific building requirements without requiring a monolithic complex structure
Solution Approach 2:
The riser shaft acts as an intermediary channel between the external wind environment and the building interior. It redirects harmful wind forces through a controlled path (entrance → riser shaft → exit) to a safe discharge location above the roof, transforming the direct harmful impact into a managed flow process
2Object-affected harmful factors
If lateral face elements are positioned at a distance from building walls, then airflow redirection is improved, but space occupation increases
Solution Approach 1:
The device utilizes the vertical dimension by extending riser shafts from ground level through the building to discharge above the roof. This vertical airflow management allows effective wind protection without requiring extensive horizontal space, as the protection mechanism operates primarily in the vertical dimension rather than occupying additional ground area
3Object-affected harmful factors
If multiple riser shafts are created, then wind force distribution is improved, but manufacturing complexity increases
Solution Approach 1:
Multiple riser shafts are created by positioning multiple lateral face elements at different locations on the building. Each face element independently forms its own riser shaft, allowing wind forces to be distributed across multiple channels. This segmented approach simplifies manufacturing compared to creating a single complex integrated system, as each face element can be produced and installed independently
Solution Approach 2:
The system can be implemented with varying degrees of complexity - from a single lateral face element to multiple elements covering the entire building perimeter. This allows partial implementation where only critical areas are protected first, enabling phased installation and reducing initial manufacturing and installation complexity while still providing beneficial wind force distribution
