Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a thermal insulation composite system is mounted on the facade walls from the outside, then thermal insulation performance is improved, but construction complexity and cost increase due to labor-intensive installation and scaffolding requirements
Solution Approach 1:
The patent transitions from external insulation (one-dimensional surface application) to integrated insulation (three-dimensional incorporation within wall structure). The insulation material is embedded within the wall modules during manufacturing, eliminating the need for separate external insulation layers and scaffolding installation.
Solution Approach 2:
Thermal insulation is integrated into the wall modules during the prefabrication process at the manufacturing plant, before the modules are transported to the construction site. This preliminary incorporation of insulation material eliminates the need for subsequent insulation installation and scaffolding erection on-site.
2Loss of energy
If conventional external insulation systems are used, then thermal insulation is achieved, but production and assembly time increase due to labor-intensive installation processes
Solution Approach 1:
The insulation material is incorporated into the wall modules during the prefabrication process at the manufacturing plant, before the modules are transported to the construction site. This preliminary action eliminates the need for time-consuming on-site insulation installation and scaffolding erection, significantly accelerating construction assembly.
Solution Approach 2:
The patent combines the structural wall function and thermal insulation function into a single integrated wall module. The insulation material is embedded within the wall structure, merging two separate construction processes (wall construction and insulation installation) into one unified process that occurs during manufacturing.
3Loss of energy
If thermal insulation composite systems are installed externally, then energy requirements are met, but production costs increase due to additional materials and labor
Solution Approach 1:
The patent combines the structural wall function and thermal insulation function into a single integrated wall module. The insulation material is embedded within the wall structure, merging two separate construction processes (wall construction and insulation installation) into one unified process that occurs during manufacturing, thereby reducing overall production costs.
Solution Approach 2:
The insulation material is incorporated into the wall modules during the prefabrication process at the manufacturing plant, before the modules are transported to the construction site. This preliminary action eliminates the need for time-consuming on-site insulation installation and scaffolding erection, significantly accelerating construction assembly.
