Solution Overview

Problem

Existing building material manufacturing methods face challenges in achieving uniform raw material accumulation due to differences in bulk specific gravity, leading to uneven distribution and reduced durability, particularly with the formation of holes that can compromise water resistance and freeze-thaw durability.

Innovation Solution

A building material is formulated with a mixture of hydraulic materials, admixtures, and plant-based reinforcing materials, where the plant-based reinforcing material is distributed uniformly with the hydraulic material and admixture, ensuring consistent distribution on both sides of convex parts, thereby suppressing water absorption and enhancing durability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If wind classification is used to separate hydraulic material and plant-based reinforcing material, then classification occurs, but uniform accumulation is not achieved due to differences in bulk specific gravity

Engineering Contradiction:
Improveuniform accumulation of raw materialsVSAvoiddurability of building material
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The patent changes the classification mechanism from wind-based (aerodynamic) to water-based (hydrodynamic). By using water flow instead of air flow, the classification process achieves uniform distribution of both hydraulic material and plant-based reinforcing material, eliminating the non-uniform accumulation problem caused by differences in bulk specific gravity

Inventive Principle:
Principle #35Parameter changes

2Quantity of substance

If auxiliary fan is added to blow wind in conveying direction, then opposite side of convex parts is filled, but accumulation speed decreases

Engineering Contradiction:
Improvefilling of opposite side of convex partsVSAvoidaccumulation speed of powder raw materials
Core Design Contradiction:
Quantity of substanceVSProductivity

Solution Approach 1:

The patent replaces the mechanical wind-blowing system (main fan and auxiliary fan) with a water-based classification system. The water flow naturally carries and distributes the raw materials according to their specific gravity, achieving uniform filling of convex parts without the need for additional fans, thus maintaining high accumulation speed

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If piece of wood is used as plant-based reinforcing material, then durability is improved, but non-uniform distribution occurs due to low bulk specific gravity

Engineering Contradiction:
Improvedurability of building materialVSAvoiduniform distribution of plant-based reinforcing material
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The patent changes the classification medium from air to water, which allows the plant-based reinforcing material (piece of wood) to be uniformly distributed. The water-based system provides sufficient buoyancy and carrying capacity for the low-density wood pieces, ensuring they are evenly distributed throughout the building material matrix, thus achieving both durability and manufacturing precision

Inventive Principle:
Principle #35Parameter changes

AI summary

[Object] To provide a building material having excellent durability. [Solution] A building material has a convex part formed on a surface thereof, the convex part including a first lateral surface part and a second lateral surface part corresponding to the first lateral surface part. The building material is formed from a mixture containing a hydraulic material, an admixture, and a plant-based reinforcing material, and the plant-based reinforcing material at least in the convex part is distributed in the mixture with the hydraulic material and the admixture attached to the plant-based reinforcing material. A distribution of the plant-based reinforcing material in the first lateral surface part and a distribution of the plant-based reinforcing material in the second lateral surface part are substantially the same. Desirably, the convex part includes a first edge part that is an edge part of the first lateral surface part and a second edge part that is an edge part of the second lateral surface part and that corresponds to the first edge part, and a distribution of holes formed in the first edge part and a distribution of holes formed in the second edge part are substantially the same.
