Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If one-size-fits-all height control by block basis is applied, then planning simplicity is improved, but manufacturing precision of constructible height deteriorates
Solution Approach 1:
The patent divides the urban area into multiple analysis blocks and further segments each block into grid cells. This segmentation allows different height control strategies to be applied to different areas, enabling precise control of constructible heights while maintaining overall planning organization. The grid-based segmentation transforms the one-size-fits-all approach into a differentiated, precise control system.
Solution Approach 2:
The patent implements local quality by generating unique height control plans for each analysis block based on its specific solar and visual constraints. Instead of uniform height control across the entire urban area, the system calculates customized maximum constructible heights for each block, ensuring that local characteristics (solar exposure, visual corridors) are preserved while allowing capacity increase where appropriate.
2Productivity
If arbitrary capacity increase is applied, then productivity of urban renewal is improved, but object-affected harmful factors deteriorate
Solution Approach 1:
The patent applies preliminary anti-action by pre-calculating solar and visual constraints before determining capacity increase potentials. The system generates solar envelopes and visual envelopes that define maximum constructible heights, preventing designs that would harm solar exposure or visual corridors. This preliminary constraint analysis ensures that capacity increase does not adversely affect surrounding residential areas' solar environments.
Solution Approach 2:
The patent implements feedback mechanisms by using solar and visual constraint analyses to continuously adjust and optimize height control plans. The system evaluates the impact of proposed constructions on solar exposure and visual corridors, and uses this feedback to refine the maximum constructible height determinations, ensuring that productivity gains do not compromise environmental quality.
3Measurement precision
If detailed solar and visual constraint analysis is performed, then measurement precision of constraints is improved, but device complexity deteriorates
Solution Approach 1:
The patent uses computational algorithms and software systems as intermediaries to perform complex solar and visual constraint analyses. These computational tools act as mediators between the physical urban environment and the design decisions, automatically calculating solar envelopes, visual corridors, and maximum constructible heights based on input parameters, thereby achieving high measurement precision without requiring complex manual analysis procedures.
Solution Approach 2:
The patent replaces traditional manual or mechanical methods of solar and visual analysis with computational methods. Instead of using physical models or manual calculations, the system uses computer-based algorithms to perform constraint analyses, generating precise height control plans through digital computation. This substitution reduces the complexity of the analysis system while maintaining or improving measurement precision.
