Solution Overview

Problem

Conventional jointless wall structures with elastic coating materials face challenges in achieving an uneven pattern on the surface without increasing effort in the coating process and with minimal variation in the finished design, while maintaining weatherproofing and waterproofing.

Innovation Solution

A wall structure utilizing a mesh-shaped body made from expandable materials, such as polyester or nylon, with a polythiourethane or acrylic elastic joint process material, and an acrylic elastic coating material, where the mesh is placed between abutting wall materials to create an uneven pattern that is reinforced and coated uniformly, suppressing expansion and contraction, and ensuring adequate weatherproofing and waterproofing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If a pattern is applied by means of the method for applying an elastic coating material, then an uneven pattern can be formed on the wall surface, but the effort required in coating increases and variation in the finished design increases

Engineering Contradiction:
Improveuneven pattern on wall surfaceVSAvoideffort required in coating process
Core Design Contradiction:
ShapeVSEase of manufacture

Solution Approach 1:

The wall material is pre-formed with an uneven pattern on its surface before the elastic coating material is applied. This preliminary formation of the pattern eliminates the need for complex manual patterning during the coating process, thereby reducing coating effort while maintaining design consistency.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The uneven pattern is created as a physical copy or replica on the wall material surface itself, rather than being manually crafted during coating. This copied pattern is then reproduced uniformly across all wall materials, reducing variation in the finished design.

Inventive Principle:
Principle #26Copying

2Shape

If a pattern is applied by means of the method for applying an elastic coating material, then an uneven pattern can be formed on the wall surface, but variation in the finished design increases

Engineering Contradiction:
Improveuneven pattern on wall surfaceVSAvoidvariation in finished design
Core Design Contradiction:
ShapeVSManufacturing precision

Solution Approach 1:

The uneven pattern is pre-formed on the wall material surface with precise, consistent dimensions before coating. This ensures that each wall material piece has the same pattern characteristics, thereby reducing variation in the finished design when coated with elastic material.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The pattern dimensions and characteristics are controlled as fixed parameters during wall material manufacturing, ensuring consistency. This parameter control maintains manufacturing precision across all wall materials, reducing variation in the final coated appearance.

Inventive Principle:
Principle #35Parameter changes

3Shape

If elastic coating material is applied to cover the wall surface, then jointless finish is achieved, but weatherproofing and waterproofing may be compromised

Engineering Contradiction:
Improvejointless wall surfaceVSAvoidweatherproofing and waterproofing
Core Design Contradiction:
ShapeVSReliability

Solution Approach 1:

The wall structure uses a composite system combining the wall material with elastic coating material and joint process material. This composite structure maintains the jointless aesthetic while the elastic properties and material composition provide weatherproofing and waterproofing functionality.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The elastic coating material and joint process material are formulated with specific physical and chemical parameters that provide both the jointless appearance and protective properties. The material composition is optimized to achieve both aesthetic and functional requirements simultaneously.

Inventive Principle:
Principle #35Parameter changes
