By collaborating with DFX experts across methodologies, medical device companies can enhance their innovative designs, making them not only groundbreaking in functionality but also optimized for manufacturing, cost-effectiveness, reliability, and user experience.
This holistic approach to design can lead to products that are more likely to succeed in the market and provide sustained value to healthcare providers and patients.
Let's dive deeper into each design area with examples and potential innovation outcomes for each.
The focus and discipline of DFX is a powerful tool if used as part of a broader strategic approach to developing product/process differentiation, and a sustainable advantage against competition. Involve Design for X in Strategy. Once your team has determined the focus of your strategy, place the focus of design on developing competitive advantage.
At Boston Engineering, DFX is a core part of creating values during our product development process. We focus on several key DFX areas that align with our expertise:
- Design for Manufacturability (DFM)
- Design for Assembly (DFA)
- Design for Cost (DFC)
- Design for Testability (DFT)
- Design for Reliability (DFR)
- Design for Serviceability/Maintainability (DFS)
- Design for Usability (DFU)
- Design for Modularity (DFMo)

Design for Manufacturability (DFM)
Example: For the brain-computer interface for paralyzed patients
A DFM expert could help design the interface's components to be easily manufactured at scale. This might involve:
- Simplifying the geometry of neural sensors for easier production
- Selecting materials compatible with automated manufacturing processes
- Standardizing components across different product variants
Innovation outcome: A more scalable production process, potentially reducing costs and improving availability of this cutting-edge technology.
Design for Assembly (DFA)
Example: For the portable, AI-powered ultrasound device
Working with a DFA expert could focus on:
- Reducing the number of components in the device
- Designing parts that can only be assembled in the correct orientation
- Incorporating snap-fit connections to minimize the need for fasteners
Innovation outcome: A more compact and robust device that's quicker to assemble, potentially enabling point-of-care use in various medical settings.
Design for Cost (DFC)
Example: For the non-invasive continuous glucose monitor
A DFC expert might suggest:
- Using multi-functional components to reduce part count
- Identifying alternative materials that maintain performance but at lower cost
- Optimizing the design for minimal waste during production
Innovation outcome: A more affordable device, potentially increasing accessibility for diabetic patients and market penetration.
Design for Testability (DFT)
Example: For the minimally invasive heart valve repair tool
DFT considerations could include:
- Incorporating built-in self-test capabilities
- Designing easily accessible test points
- Creating modular subassemblies that can be tested independently
Innovation outcome: Improved quality assurance and easier regulatory compliance, crucial for a high-risk surgical device.
AL & ML in Health Care - The Medical Workplace Multiplier
In this new Whitepaper, learn how AI and ML can enhance the medical workforce’s abilities and improve patient outcomes.
While some view AI as a potential job replacement threat, the reality is that these advanced capabilities are better positioned as “workforce multipliers” that will amplify the abilities of doctors, nurses, technicians and other medical professionals.

Artificial intelligence and machine learning are emerging technologies that have immense potential to reshape healthcare delivery and medical practice.
Design for Reliability (DFR)
Example: For the novel antimicrobial wound dressing
A DFR expert might focus on:
- Conducting failure mode and effects analysis (FMEA)
- Designing redundancies for critical functions
- Selecting materials resistant to degradation in typical use environments
Innovation outcome: A more dependable product that maintains its antimicrobial properties over time, potentially improving patient outcomes.
Design for Serviceability/Maintainability (DFS)
Example: For the surgical robot
DFS considerations could include:
- Designing easily replaceable modules
- Incorporating diagnostic systems for quick problem identification
- Ensuring accessibility to components likely to need servicing
Innovation outcome: Reduced downtime and maintenance costs, potentially increasing adoption in healthcare facilities.
Design for Usability (DFU)
Example: For the portable ultrasound device
A DFU expert might suggest:
- Conducting extensive user research with healthcare professionals
- Designing an intuitive user interface for the AI features
- Ensuring the device is comfortable to hold and operate for extended periods
Innovation outcome: Improved user adoption and effectiveness, potentially expanding the device's use cases.
Design for Modularity (DFMo)
Example: For the brain-computer interface
DFMo considerations could include:
- Creating a standardized interface between the neural sensors and signal processing unit
- Designing interchangeable modules for different types of robotic limbs
- Developing a scalable architecture to accommodate future enhancements
Innovation outcome: A more flexible and upgradeable system, potentially extending the product's lifespan and adaptability to different patient needs.
