A modular house design featuring a double-shell facade wall with a heat-insulating cavity between the inner and outer wall shells, filled with bulk or blow-in insulating materials like cellulose, which eliminates the need for external thermal insulation systems and scaffolding, and ensures efficient energy performance.

Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
Improvethermal insulation performanceVSAvoidconstruction complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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.

Inventive Principle:
Principle #10Preliminary action

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

Engineering Contradiction:
Improvethermal insulationVSAvoidconstruction efficiency
Core Design Contradiction:
Loss of energyVSProductivity

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.

Inventive Principle:
Principle #10Preliminary action

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.

Inventive Principle:
Principle #5Merging (Combining)

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

Engineering Contradiction:
Improveenergy performanceVSAvoidproduction cost
Core Design Contradiction:
Loss of energyVSEase of manufacture

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.

Inventive Principle:
Principle #5Merging (Combining)

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.

Inventive Principle:
