Solution Overview
Problem
Water condensation in building infrastructure leads to humidity, mold, mildew, water damage, and safety hazards due to the inability of existing technologies to effectively manage condensation, particularly in areas requiring regular cleaning.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If condensation is allowed to accumulate on horizontal surfaces, then liquid collection occurs, but water damage, mold, and humidity problems result
Solution Approach 1:
The patent extracts the harmful liquid accumulation by providing designated drainage points that actively remove condensation from horizontal surfaces. The fluid control layer channels liquid to specific drainage locations, preventing widespread accumulation that causes water damage and mold growth.
Solution Approach 2:
The fluid control layer acts as an intermediary between the condensation source and the environment. It captures, transports, and directs liquid through angled channels to drainage points, serving as a mediating system that prevents direct contact between accumulated water and building infrastructure.
2Ease of operation
If regular cleaning is performed on surfaces, then hygiene is maintained, but liquid accumulation during cleaning operations occurs
Solution Approach 1:
The drainage points extract excess liquid introduced during cleaning operations. The fluid control layer captures cleaning liquids and directs them to designated drainage locations, preventing accumulation that would otherwise require extensive drying time or cause slip hazards.
Solution Approach 2:
The system provides self-service liquid management during cleaning operations. As cleaning liquids are applied, the fluid control layer automatically captures and transports them to drainage points without requiring additional manual intervention for liquid removal.
3Ease of manufacture
If channels are oriented parallel to longitudinal axis, then manufacturing is simplified, but capillary movement against gravity is reduced
Solution Approach 1:
The patent changes the orientation parameter of the channels from parallel to angled relative to the longitudinal axis. This angular orientation optimizes the capillary action vector to better counteract gravitational force, accelerating liquid movement along the surface while remaining manufacturable through standard molding techniques.
4Productivity
If surface area for evaporation is increased, then evaporation rate improves, but device complexity increases
Solution Approach 1:
The patent utilizes the angular dimension of channel orientation to achieve multiple functions simultaneously. The angled channels provide both liquid transport pathways and evaporation surfaces, effectively using three-dimensional spatial arrangement to increase functional surface area without proportionally increasing structural complexity.
