Solution Overview
Problem
Current thermal insulation materials in the Gulf region are expensive, have poor mechanical properties, and are not widely used by local contractors, necessitating a cost-effective solution with improved mechanical and thermal performance, water resistance, and ease of handling.
Innovation Solution
A composite thermal insulation material composed of ground date pits and polyester resin, where the date pits are crushed to a particle size of less than 800 μm and mixed with polyester resin, along with an initiator compound, to form a cured thermal insulator material with enhanced mechanical and thermal properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional thermal insulation materials (polyurethane, polystyrene, mineral wool) are used, then thermal insulation performance is achieved, but mechanical properties are poor and cost is high
Solution Approach 1:
The patent creates a composite material combining date pits (natural filler) with polyester resin (polymer matrix) to achieve both thermal insulation and mechanical strength. The composite structure allows the date pits to provide thermal insulation while the polyester resin provides structural integrity and mechanical properties, resolving the contradiction between insulation performance and mechanical strength.
2Temperature
If conventional thermal insulation materials are used, then thermal insulation performance is achieved, but cost is high and ease of handling is poor
Solution Approach 1:
The patent uses date pits, an abundant agricultural waste product, as the filler material instead of expensive conventional insulation materials. This substitution dramatically reduces material cost while maintaining thermal insulation performance. The composite material also improves ease of handling compared to conventional materials like mineral wool.
3Strength
If date pits are used as filler in composite material, then cost is reduced and mechanical properties are improved, but thermal conductivity may increase
Solution Approach 1:
The patent optimizes the particle size of date pits to less than 800 μm and controls the filler content at 40-60 wt% to balance thermal insulation and mechanical properties. By carefully controlling these parameters, the composite achieves both improved mechanical strength and acceptable thermal insulation performance, preventing excessive thermal conductivity.
