Solution Overview

Problem

Existing medical units face challenges in quickly assembling and reconfiguring temporary wards for epidemic prevention, as they are often large, difficult to transport, and lack effective air isolation, leading to potential cross-infection risks during outbreaks like COVID-19.

Innovation Solution

A prefabricated modular inpatient unit made from recycled and environmentally friendly materials, featuring modular design with antibacterial airtight panels, a negative pressure air conditioning system, and quick assembly capabilities, allowing for reconfiguration and redeployment as intensive care, general, or isolation units, including outdoor use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional temporary wards are built using existing technology, then they can provide medical treatment space, but they are large-sized, difficult to transport, and take a long time to assemble

Engineering Contradiction:
Improveassembly speedVSAvoidmodular design complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The temporary ward is divided into multiple modular units that can be independently manufactured, transported, and assembled. Each module contains standardized components (walls, ceiling, floor, ventilation systems) that can be quickly connected using standardized interfaces, dramatically reducing assembly time while maintaining functional integrity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The modular design creates universal building blocks that can be configured for different medical purposes (isolation rooms, general wards, intensive care units) by arranging the same basic modules in different configurations. This standardized modular system reduces manufacturing complexity while enabling rapid deployment and reconfiguration

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If negative pressure isolation rooms are used to prevent cross-infection, then air leakage is prevented, but it is difficult to collect equipment, materials and manpower to organize many such rooms in a short period

Engineering Contradiction:
Improveair isolation effectivenessVSAvoiddeployment speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The negative pressure ventilation systems, airtight sealing components, and isolation features are pre-integrated into the modular units during manufacturing. This preliminary preparation of critical isolation components allows the modules to be deployed as complete functional units, eliminating the need to assemble complex ventilation systems on-site and enabling rapid deployment of multiple isolation rooms

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The air isolation system is segmented into modular components that can be independently tested and certified before deployment. Each module comes with pre-installed negative pressure ventilation and airtight sealing, allowing multiple isolation rooms to be rapidly deployed by simply assembling the pre-prepared modules without collecting and installing complex equipment separately

Inventive Principle:
Principle #1Segmentation

3Area of stationary object

If integrated large-sized temporary wards are built, then they can provide sufficient treatment capacity, but they are difficult for transportation and assembly takes a long time

Engineering Contradiction:
Improvetreatment space areaVSAvoidtransportation ease
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

Large treatment facilities are segmented into smaller modular units that can be transported using standard transportation infrastructure (trucks, containers). The modules are designed to be compact for transport but can be expanded when assembled, providing large treatment capacity through the aggregation of multiple small units rather than requiring transport of a single large structure

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The modular design allows smaller functional units to be nested within larger assembly structures during transport and storage. The modules can be stacked or nested compactly, maximizing transportation efficiency while maintaining the capability to expand into large treatment facilities when deployed

Inventive Principle:
Principle #7Nested doll (Nesting)
