Innovation Solution
A construction method involving the application of charcoal paint on floors, walls, and ceilings, arrangement of Obi-sugi flooring members, application of diatomaceous earth on walls, and spraying of an antioxidant aqueous solution to control humidity, purify air, and eliminate odors, while providing insulation and antibacterial effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional construction materials and methods are used, then construction cost and time are controlled, but the indoor environment becomes unhealthy with high levels of volatile organic compounds, mold growth, and poor humidity control
Solution Approach 1:
The construction process is divided into distinct sequential steps: charcoal paint application, Obi-sugi flooring arrangement, diatomaceous earth application, and antioxidant spraying. Each step addresses specific environmental concerns independently, allowing systematic improvement of indoor air quality, humidity control, and mold prevention without overwhelming complexity
Solution Approach 2:
The invention combines multiple natural materials with complementary functions: charcoal paint for VOC absorption, Obi-sugi wood for humidity regulation, diatomaceous earth for mold inhibition, and antioxidant solution for overall environmental enhancement. This composite approach creates synergistic effects that significantly improve indoor environment while using naturally decomposable materials
2Object-affected harmful factors
If charcoal paint, Obi-sugi flooring, diatomaceous earth, and antioxidant solutions are applied, then a healthy and comfortable indoor environment is achieved, but the construction process becomes more complex and time-consuming
Solution Approach 1:
Charcoal paint is applied to walls and ceilings before installing flooring, and diatomaceous earth is applied to walls before final finishing. These preliminary actions ensure that VOC absorption and mold prevention mechanisms are in place before occupants move in, maximizing health benefits from the outset
Solution Approach 2:
The charcoal paint, Obi-sugi flooring, and diatomaceous earth create a self-regulating environment that automatically controls humidity levels and absorbs VOCs without requiring active maintenance or additional energy input, reducing long-term time investment
3Reliability
If natural materials like charcoal paint and diatomaceous earth are used, then health risks are reduced, but the durability and maintenance requirements become uncertain
Solution Approach 1:
The charcoal is converted into paint form with specific particle size distributions (0.1-10 μm) optimized for air purification efficiency. The diatomaceous earth is applied at controlled thicknesses (0.1-1mm) to ensure both mold prevention and breathability. These parameter optimizations maintain natural material benefits while enhancing performance reliability
Solution Approach 2:
The charcoal paint continuously absorbs VOCs, the Obi-sugi flooring continuously regulates humidity through its natural properties, and the diatomaceous earth continuously prevents mold growth. This continuous passive action ensures sustained health protection without requiring periodic replacement or maintenance interventions
