Solution Overview
Problem
Existing modular residential buildings face inefficiencies in heating, ventilation, and sewerage systems, particularly in maintaining consistent temperatures and energy efficiency, which affects scalability and energy consumption.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If individual heating and cooling systems are installed in each module, then temperature control flexibility is improved, but energy consumption and system complexity increase
Solution Approach 1:
The patent merges heating and cooling systems into a shared infrastructure by installing insulation layers and air canals in the common framework structure that serves all modules. A single ventilation system with centralized control units serves multiple modules, eliminating the need for duplicate individual systems while maintaining temperature control flexibility through adjustable vents and controllable air flow in each module.
Solution Approach 2:
The framework structure performs multiple functions: it provides structural support, houses insulation layers for thermal management, contains air canals for ventilation, and supports technical rooms. The ventilation system serves both heating and cooling functions across all modules through a single multi-functional infrastructure, reducing overall system complexity and energy consumption.
2Productivity
If modular construction is used, then construction efficiency and scalability are improved, but heating and ventilation system efficiency deteriorates
Solution Approach 1:
The patent combines the heating and ventilation infrastructure with the modular framework structure itself. Insulation layers are integrated into the framework members, and air canals are formed within the framework structure, creating a unified system that maintains efficiency while enabling modular construction and rapid deployment.
Solution Approach 2:
The patent applies localized thermal management by providing adjustable ventilation vents and controllable air flow in each module while maintaining a shared insulated framework. This allows each module to be optimized for its specific thermal needs while benefiting from the collective efficiency of the shared insulated structure.
3Device complexity
If shared technical infrastructure is provided, then system complexity is reduced, but adaptability to individual module needs decreases
Solution Approach 1:
The patent segments the ventilation and heating control into modular units that can be independently adjusted. Each module has its own controllable vents, adjustable air flow, and accessible technical room, allowing individual customization while maintaining a simple shared infrastructure for air distribution and insulation.
Solution Approach 2:
The patent incorporates dynamic control elements such as adjustable ventilation vents, controllable air flow mechanisms, and accessible technical rooms that allow the system to adapt to changing individual module needs. The shared infrastructure remains simple and fixed, while the terminal control points are dynamic and customizable.
