Solution Overview
Problem
Vacuum heat-insulating materials used in dwelling walls are prone to chemical reactions with moisture when ruptured, leading to potential hydrogen generation and instability, which is not adequately addressed in existing technologies.
Innovation Solution
A dwelling wall configuration with a vacuum heat-insulating material having an outer cover and an inner member that does not generate hydrogen upon contact with moisture, utilizing an inorganic fiber core material and an adsorbent that does not react with water, ensuring stability even if the outer cover is ruptured.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a vacuum heat-insulating material with conventional inner members is used in a dwelling wall, then heat-insulation performance is improved, but hydrogen generation occurs when the outer cover material is ruptured and moisture enters
Solution Approach 1:
The patent changes the chemical composition parameter of the inner member material from conventional organic materials to inorganic materials (such as glass fiber, rock wool, or slag wool) that do not generate hydrogen when contacting moisture, while maintaining the vacuum heat-insulation function
Solution Approach 2:
The patent uses composite material structure combining inorganic fiber materials with binding agents to create an inner member that provides both structural integrity and chemical stability against moisture, preventing hydrogen generation while maintaining heat-insulation properties
2Reliability
If the outer cover material is damaged in a dwelling wall with vacuum heat-insulating material, then water of liquid enters the inside, but chemical reaction with inner members causes instability
Solution Approach 1:
The patent creates a chemically inert environment by selecting inorganic materials for the inner member that do not react with moisture, effectively making the material resistant to chemical reactions even when the vacuum seal is broken and water enters
Solution Approach 2:
The patent changes the chemical reactivity parameter of the inner member by selecting materials with low chemical reactivity toward water, such as inorganic fibers and stable binding agents, thereby preventing harmful chemical reactions when moisture intrusion occurs

AI summary
A dwelling wall includes: a vacuum heat-insulating material including an outer cover material, and an inner member which is sealed in a tightly closed and decompressed state on the inside of the outer cover material; and a wall material. In addition, the vacuum heat-insulating material is disposed on a rear surface side of the wall material, and the inner member is configured of a material which does not generate hydrogen in a case of coming into contact with moisture of liquid. According to the configuration, even in a case where the vacuum heat-insulating material used in the dwelling wall is ruptured and water of liquid comes into contact with the inner member, it is possible to realize excellent stability of the dwelling wall.
