Polymer Cement-Granite Composite Tomb Box Design
Solution Overview
Problem
Current tomb boxes, either artificial stone or natural stone, fail to meet the demand for luxury and durability due to limitations in bending strength, brittleness, and resource scarcity of natural stones.
Innovation Solution
A polymer cement-granite composite tomb box with a layered structure, comprising granite slabs and polymer cement, where the polymer cement is composed of specific proportions of cement, aggregates, superplasticizer, and additives, providing high bending strength and impact resistance, and a method for its preparation involving mixing and curing to achieve a strong and durable product.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If natural stone is used to make tomb boxes, then beauty and luxury are achieved, but processing difficulty and cost increase significantly
Solution Approach 1:
The patent creates a composite tomb box structure combining granite slabs with polymer cement. The granite provides aesthetic appearance and durability, while the polymer cement provides ease of processing and structural support, resolving the contradiction between beauty and manufacturing ease
Solution Approach 2:
The tomb box is divided into multiple components: granite slabs for aesthetic surfaces and polymer cement for structural filling and bonding. This segmentation allows each material to be used where it provides maximum benefit, reducing overall processing difficulty while maintaining luxury appearance
2Shape
If natural stone is used to make tomb boxes, then luxury and beauty are achieved, but resource scarcity becomes a problem
Solution Approach 1:
By combining polymer cement with granite slabs, the patent reduces the total volume of natural stone required compared to traditional solid stone tomb boxes. The polymer cement acts as a substitute for less critical stone portions, conserving natural resources while maintaining aesthetic appearance through strategic use of granite surfaces
Solution Approach 2:
Natural granite is applied only where aesthetic appearance is critical (visible surfaces), while polymer cement is used for structural portions where natural stone is not visible. This local quality approach minimizes natural stone consumption while preserving luxury appearance where needed
3Loss of substance
If polymer cement is used to make tomb boxes, then resource saving and economic benefits are achieved, but bending strength is insufficient and brittleness increases
Solution Approach 1:
The patent creates a composite where polymer cement is reinforced with granite slabs and aggregate particles. The granite components provide high bending strength and reduce brittleness, while the polymer cement matrix provides resource efficiency and economic benefits, achieving both strength and resource saving simultaneously
Solution Approach 2:
The patent modifies the polymer cement composition by adding specific ratios of granite aggregate, sand, and chemical additives (superplasticizers, polymers, retarders) to change its mechanical parameters, achieving sufficient bending strength and reduced brittleness while maintaining resource efficiency
4Loss of substance
If polymer cement is used to make tomb boxes, then resource saving and economic benefits are achieved, but appearance becomes single-colored and unattractive
Solution Approach 1:
The composite structure combines polymer cement with granite slabs that have natural varied patterns and colors. The granite surfaces provide the aesthetic variety and luxury appearance, while the polymer cement provides resource efficiency, achieving both goals simultaneously
Solution Approach 2:
The patent applies granite materials with natural aesthetic qualities to visible surfaces where appearance matters, while using polymer cement for non-visible structural portions. This local quality differentiation achieves attractive appearance with resource saving

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composite tomb box offers high bending strength, impact resistance, and reduced brittleness, while conserving natural stone resources, with a simpler preparation process and improved aesthetic appeal, meeting the requirements of luxury and durability.
Implementation Method 1

the polymer cement consists of 20-35 parts by weight of a cement, 25-45 parts by weight of a fine aggregate, 25-55 parts by weight of a coarse aggregate, 0.01-0.5 part by weight of a superplasticizer, 1-6 parts by weight of a polymer
Implementation Method 3
coating a surface of the polymer cement with a water-in-water granite coating to produce the tomb box
Implementation Method 4
