Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If only NIR image measurement device or moisture amount estimation device is used, then measurement simplicity is maintained, but temporal change of adhesion moisture amount cannot be appropriately estimated in outdoor environments
Solution Approach 1:
The patent combines multiple measurement devices (NIR image measurement device, fine particle tracking device, spray device) into an integrated system. The NIR device measures moisture distribution on the structure surface, the fine particle tracking device captures atmospheric moisture transport, and the spray device simulates rain conditions. These devices work together to comprehensively estimate temporal changes in adhesion moisture amount under outdoor conditions.
Solution Approach 2:
The patent introduces a computer as an intermediary that processes data from multiple devices and performs calculations to estimate temporal changes. The computer integrates NIR spectrum data, fine particle tracking data, and environmental parameters to compute adhesion moisture amount changes over time, serving as a mediator that synthesizes information from various measurement sources.
2Reliability
If structure is exposed to outdoor environment for corrosion testing, then real-world durability is evaluated, but measurement of adhesion moisture distribution becomes difficult
Solution Approach 1:
The patent performs preliminary measurements by placing a test object in the actual outdoor installation environment before final structure installation. The system measures adhesion moisture distribution on the test object under real environmental conditions (wind, rain, sunlight), capturing data that reflects actual corrosion-prone conditions. This preliminary testing provides accurate baseline data for evaluating structure durability.
