Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a twin facade arrangement is used to generate alternative energy through chimney effect, then energy generation capability is improved, but local environmental quality and impact on surrounding ecosystem remain limited
Solution Approach 1:
The twin facade arrangement is enhanced by integrating multiple functional systems: the carbon dioxide segregation apparatus using biological principles (algae/bacteria), the nitrogen oxide segregation apparatus using chemical catalysis, and the sulfur oxide segregation apparatus using absorption materials. This multi-functional integration transforms the facade from a single energy-generation system into a comprehensive environmental management system that simultaneously produces energy and improves local air quality.
Solution Approach 2:
The patent combines five distinct functions into one integrated facade system: (1) solar energy capture through transparent solar cells, (2) vertical air stream generation via chimney effect, (3) carbon dioxide segregation through biological processes, (4) nitrogen oxide segregation through catalytic conversion, and (5) sulfur oxide segregation through absorption. This merging of functions maximizes both energy generation and environmental benefits within the same structural framework.
2Object-affected harmful factors
If carbon dioxide segregation apparatus is added to the twin facade arrangement, then air quality improvement is enhanced, but device complexity increases
Solution Approach 1:
The carbon dioxide segregation apparatus is nested within the facade interspace, utilizing the existing vertical air stream pathway. The biological segregation medium (algae or bacteria) is contained within the interspace volume already dedicated to air flow, rather than adding external equipment. This nesting approach allows the segregation function to be integrated into the existing chimney effect structure, minimizing additional complexity.
Solution Approach 2:
The carbon dioxide segregation apparatus operates autonomously by utilizing the naturally flowing vertical air stream generated by the chimney effect. The biological agents (algae or bacteria) self-replicate and self-maintain the segregation process without external intervention, converting carbon dioxide into oxygen and biomass automatically as air passes through the interspace.
3Object-affected harmful factors
If multiple pollutant segregation apparatus are integrated into the twin facade, then comprehensive environmental benefit is achieved, but manufacturing complexity increases
Solution Approach 1:
The facade is divided into distinct functional zones within the interspace: a first region containing the carbon dioxide segregation apparatus, a second region containing the nitrogen oxide segregation apparatus, and a third region containing the sulfur oxide segregation apparatus. Each segment handles a specific pollutant type, allowing for modular manufacturing and assembly of specialized components that can be independently optimized and replaced.
Solution Approach 2:
Different segregation mechanisms are applied to different pollutant types based on their specific chemical and physical properties: biological processes for carbon dioxide, catalytic conversion for nitrogen oxides, and absorption for sulfur oxides. Each apparatus is tailored to its specific function with locally optimized materials and processes, rather than using a single uniform approach for all pollutants.
