Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fixed clean room is constructed according to client's physical space and planned demand, then the clean area provides stable and reliable environment for drug handling, but the construction is time-consuming and has high construction and maintenance costs

Engineering Contradiction:

Improveclean area stabilityVSAvoidconstruction time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The clean room system is divided into modular units that can be pre-fabricated and assembled on-site. Each module contains complete functional elements (HVAC, lighting, flooring) that can be independently manufactured and quickly installed, reducing construction time while maintaining reliability through standardized designs

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Clean room modules are pre-assembled and pre-tested in controlled manufacturing environments before delivery to the client site. This preliminary preparation includes installing HVAC systems, lighting, and flooring in advance, allowing for quality assurance and reducing on-site construction time while ensuring reliable performance

Inventive Principle:

Principle #10Preliminary action

2Reliability

Engineering Contradiction:

Improveclean area stabilityVSAvoidconstruction cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The system uses modular construction that can be manufactured in standardized facilities and assembled on-site, reducing labor costs and material waste. The modular approach allows for economies of scale in manufacturing while maintaining reliable clean room performance through standardized quality control

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The clean room modules are designed with universal applications that can serve multiple functions (drug preparation, administration, patient care) and be deployed in various settings. This multi-functionality reduces the need for specialized custom construction, lowering costs while maintaining reliable performance for different medical applications

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If bedside manipulation of injectables is performed, then the treatment can be provided at patient location, but there is added risk of contamination and error of dose fractionation and exposure to toxic substances

Engineering Contradiction:

Improvetreatment accessibilityVSAvoidcontamination risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The mobile clean room module serves as an intermediary between the pharmacy and patient bedside. It provides a controlled clean environment for drug preparation and can be transported to various patient locations, maintaining treatment accessibility while eliminating contamination risks associated with bedside manipulation through its sealed, pressurized design

Inventive Principle:

Principle #24Intermediary (Mediator)

4Reliability

If outsourcing manipulation is chosen, then the handling of injectables can be performed by specialized facilities, but the high cost, displacement and proximity of urban centers are issues

Engineering Contradiction:

Improvedrug handling qualityVSAvoidlogistical complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system transitions from static, fixed-location clean rooms to dynamic mobile modules that can be moved between facilities. This allows specialized drug handling capabilities to be distributed to multiple locations, reducing logistical complexity of outsourcing while maintaining high-quality handling through standardized modular designs that can be deployed anywhere

Inventive Principle:

Principle #15Dynamics
