Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If coating material is applied over a wide area to improve seismic performance, then seismic performance is improved, but cost and labor increase
Solution Approach 1:
The patent applies different coating patterns (different coating areas and thicknesses) to different regions of the building based on seismic analysis results. High-risk areas receive thicker or more extensive coating while low-risk areas receive minimal or no coating, optimizing both seismic performance and cost efficiency.
Solution Approach 2:
The building is divided into multiple regions with different coating requirements. The coating pattern is segmented into various zones based on seismic vulnerability assessment, allowing selective application of coating material only where necessary for improving seismic performance.
2Reliability
If coating material is applied over a wide area to improve seismic performance, then seismic performance is improved, but work amount increases
Solution Approach 1:
The patent identifies specific high-risk regions requiring coating application and excludes low-risk areas, thereby reducing the total work area while maintaining effective seismic reinforcement where most needed.
Solution Approach 2:
Instead of applying uniform coating across the entire building, the patent applies coating partially only to critical areas identified through seismic analysis, achieving sufficient seismic performance improvement with reduced labor input.
3Quantity of substance
If multiple coating patterns with different areas and thicknesses are determined, then optimization of material usage is achieved, but analysis complexity increases
Solution Approach 1:
The patent performs preliminary seismic vulnerability analysis of the building to identify high-risk areas before determining coating patterns. This preliminary assessment guides the subsequent determination of optimal coating areas and thicknesses, simplifying the overall optimization process.
Solution Approach 2:
The patent uses seismic analysis results as feedback to iteratively optimize coating patterns. The analysis outcomes inform adjustments to coating area and thickness, creating a feedback loop that refines material usage optimization while managing analysis complexity through structured iteration.
