Floor Slab Chamfering via Preliminary Action
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for forming chamfers on floor slab units either result in high dimensional inaccuracies, reduce the strength of joints, or are unsuitable for ultra-thin boards, and they often affect the surface glossiness and visual texture of the flooring.
Innovation Solution
A floor slab unit with chamfers is developed, featuring a substrate layer and a finish paint layer, where the chamfered area has the same finish paint layer thickness and surface glossiness as the body area, and the chamfers can be either planar or arc-shaped.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If mold pressing is used to form chamfers, then the three-dimensional effect and overall texture are improved, but the cutting accuracy deteriorates and dimensional control becomes difficult
Solution Approach 1:
The chamfer is formed on the board before the finish paint layer is applied. This preliminary formation of the chamfered structure allows subsequent cutting operations to be performed with standard accuracy, as the chamfer geometry is already established. The finish paint layer is then applied to the pre-chamfered surface, ensuring that the final product achieves both the desired three-dimensional effect and acceptable manufacturing precision.
2Shape
If mold pressing is used to form chamfers, then the chamfered structure is created, but the strength at the joint between mortise lock buckles is reduced
Solution Approach 1:
The chamfer is formed on the board before the finish paint layer is applied. This preliminary formation of the chamfered structure allows subsequent cutting operations to be performed with standard accuracy, as the chamfer geometry is already established. The finish paint layer is then applied to the pre-chamfered surface, ensuring that the final product achieves both the desired three-dimensional effect and acceptable manufacturing precision.
3Shape
If mold pressing is used to form chamfers on ultra-thin boards, then the chamfered structure is created, but the boards are damaged and rupture occurs
Solution Approach 1:
The chamfer is formed on the board before the finish paint layer is applied. This preliminary formation of the chamfered structure allows subsequent cutting operations to be performed with standard accuracy, as the chamfer geometry is already established. The finish paint layer is then applied to the pre-chamfered surface, ensuring that the final product achieves both the desired three-dimensional effect and acceptable manufacturing precision.
4Ease of manufacture
If cutting is used to form chamfers, then the manufacturing process is simplified, but the surface glossiness of the chamfered area differs significantly from the body area
