Solution Overview
Problem
Existing pipe fixing devices face challenges in reducing manufacturing costs, environmental impact, and stability, particularly when installed on sandy, gravelly, or concrete surfaces, and often require long curing times for concrete products, leading to increased costs and pollution risks.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a fixing device is made of rubber or polymer, then the manufacturing cost increases, but if made of concrete, then the curing period becomes very long (28 days on average)
Solution Approach 1:
The invention changes the material parameters by using steel-making slag mixed with polymer resin instead of conventional rubber, polymer, or concrete materials. This composite material achieves both cost reduction and rapid setting, eliminating the 28-day curing period of concrete while maintaining structural integrity for pipe support.
Solution Approach 2:
The invention employs a composite material consisting of steel-making slag and polymer resin. This composite combines the advantages of both materials: the cost-effectiveness and rapid setting of polymer with the structural strength and environmental benefits of steel-making slag, resolving the contradiction between manufacturing cost and curing time.
2Strength
If a fixing device is made of concrete, then the structural strength is sufficient, but the curing period becomes very long (28 days on average) which results in a long production period
Solution Approach 1:
The invention changes the chemical and physical parameters of the supporting material by using steel-making slag mixed with polymer resin. This combination achieves rapid setting and early strength development, reducing the production period from 28 days to a much shorter timeframe while maintaining sufficient structural strength for pipe support applications.
Solution Approach 2:
The invention uses steel-making slag, an industrial waste material, as the primary component. This waste material provides adequate structural strength for temporary or permanent pipe support without requiring the long curing time of conventional concrete, effectively creating a cost-effective and time-efficient supporting solution.
3Ease of manufacture
If a fixing device is made of conventional materials, then the manufacturing cost increases, but using steel-making slag reduces the manufacturing cost
Solution Approach 1:
The invention creates a composite material using steel-making slag mixed with polymer resin. This composite maintains the reliability needed for stable pipe support while significantly reducing manufacturing costs compared to conventional rubber or polymer materials. The bent upper end edges provide mechanical interlocking that ensures stable support.
Solution Approach 2:
The invention applies local quality enhancement by forming the upper end edges to be bent toward the first space, creating a specific structural feature that provides stable support. The steel-making slag mixed with polymer resin provides localized bonding strength at the interface between the fixing portion and the supported structure, ensuring reliability despite using waste materials.
4Ease of manufacture
If heavy metals are contained in the fixing device, then the manufacturing cost may be reduced, but environmental pollution occurs
Solution Approach 1:
The invention converts the harmful waste material (steel-making slag) into a beneficial construction material. By mixing steel-making slag with polymer resin, the invention creates an environmentally friendly composite that supports pipes effectively while preventing environmental pollution. This approach eliminates the need for heavy metals while maintaining cost-effectiveness and structural integrity.
