Solution Overview
Problem
Current thermal insulation plaster systems are inefficiently applied, have poor repeatability, and require long drying and solidification times, making it difficult to apply layers in immediate succession, and they lack recyclability and cost-effectiveness.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If thermal insulation plaster is applied using conventional methods, then the plaster can be applied to the substrate, but the application process is inefficient with poor repeatability and requires long drying and solidification times
Solution Approach 1:
The invention changes the chemical composition parameters of the plaster mixture by incorporating reactive silica sand and specific binder ratios, which accelerates the solidification reaction and reduces drying time while maintaining application efficiency
Solution Approach 2:
The invention uses a composite plaster system combining cement binder, reactive silica sand, and hollow glass microspheres, creating a material that sets faster and dries more quickly than conventional plasters while maintaining insulation properties
2Ease of manufacture
If uniform composition plaster is used, then the material is simple to manufacture, but it cannot achieve optimal thermal insulation and mechanical properties simultaneously
Solution Approach 1:
The invention applies local quality by creating a graded plaster system where the composition varies through the thickness: the outer layer has higher binder content for mechanical strength, while inner layers have higher hollow microsphere content for thermal insulation, optimizing both properties simultaneously
3Strength
If high density plaster is used, then mechanical strength is improved, but thermal insulation performance deteriorates
Solution Approach 1:
The invention creates a composite material system where cement binder and reactive silica sand provide mechanical strength, while hollow glass microspheres provide thermal insulation, achieving both high strength and low thermal conductivity in the same material
4Ease of operation
If manual application method is used, then flexibility is maintained, but application quality and repeatability are poor
Solution Approach 1:
The invention replaces manual mechanical application with an automated spray application system that delivers consistent layer thickness and composition control, improving application quality and repeatability while maintaining operational flexibility
