Engineering Smarter and Faster: Digital Solutions in Medical Device Development

The Digital Transformation of MedTech. 

Medical device development has traditionally relied on physical prototypes, bench testing, and iterative redesign. While effective, these methods are time-consuming, costly, and risky when working under tight timelines and regulatory scrutiny. 

At Boston Engineering, our Digital Solutions Center of Excellence (COE) leverages these tools to de-risk development and empower innovation. By combining digital methods with our systems engineering discipline and other COEs, we help innovators validate ideas earlier, refine designs faster, and deliver safer, smarter devices to market.

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)

The Challenge: Risks in Traditional Development

Physical prototyping has always been a cornerstone of medical device engineering. But without digital acceleration, innovators face significant hurdles: 

• High prototyping costs: Building multiple rounds of physical models can consume budgets quickly. 

• Slow iterations: Hardware changes require tooling, assembly, and testing, adding weeks or months to schedules. 

• Limited testing environments: Physical prototypes can’t easily replicate the full range of clinical conditions or user scenarios. 

• Late discovery of usability issues: Human factors challenges often emerge late, forcing redesigns that delay approval. 

• Regulatory uncertainty: Lack of robust digital data can make regulatory submissions more challenging. 

Without digital methods, teams risk longer development cycles, higher costs, and slower adoption. 

Our Approach: Digital Solutions for Faster, Safer Development 

Boston Engineering’s Digital Solutions COE provides a range of capabilities that transform how medical devices are designed and validated: 

• Simulation & Multiphysics Analysis: Testing fluid flow, thermal performance, vibration, and structural integrity in silico to identify issues early. 

• Digital Twins: Creating virtual replicas of devices to predict performance over time and under varying conditions. 

• Data Visualization & Analytics: Turning complex engineering and clinical data into actionable insights. 

• Immersive VR/AR Testing: Allowing clinicians to interact with virtual prototypes to identify usability challenges before physical builds. 

• Virtual Verification: Mapping requirements to digital testing scenarios, reducing the reliance on costly hardware iterations. 

These tools don’t replace physical testing — they complement it. By catching problems early and refining designs digitally, we ensure physical prototypes are built with greater confidence and fewer surprises. 

Device Examples: Where Digital Solutions Deliver Value

Boston Engineering has applied digital solutions across a range of medical technologies, including: 

• Imaging systems that require radiation safety validation and consistent performance under varying conditions. 
• Surgical navigation platforms where VR-based user interface testing improves adoption and usability. 
• Infusion pumps where digital twins predict long-term performance and reliability. 
• Connected devices where data visualization provides insights into real-world patient use patterns.

Case Study: Accelerating Surgical Navigation Adoption

A medical technology company approached Boston Engineering with a new surgical navigation system. The device had advanced capabilities, but clinicians found the interface unintuitive and difficult to integrate into their workflow. Physical prototypes were expensive and time-consuming to modify, slowing progress toward regulatory readiness. 

Our role: 

• Used virtual reality simulations to place surgeons in a digital environment where they could interact with the system as if it were real. 
• Captured feedback on usability, workflow integration, and ergonomics without the cost of physical rework. 
• Applied data visualization to analyze patterns of use, identifying where the interface created friction. 
• Collaborated with our Design for X COE to refine the interface design for manufacturability and clinical efficiency. 

The outcome: 

• Clinician adoption improved significantly thanks to an intuitive, streamlined user interface. 
• Development timelines were accelerated by reducing reliance on physical prototypes. 
• The device entered verification with higher confidence in usability and regulatory readiness. 

Broader Results: What Digital Solutions Deliver in MedTech

Across programs, Boston Engineering’s Digital Solutions COE has enabled innovators to achieve: 

• Reduced development costs by minimizing the number of physical prototypes. 
• Faster time-to-market through rapid digital iterations. 
• Improved safety and reliability with predictive modeling and digital stress testing. 
• Higher clinician adoption by validating usability early in immersive environments. 
• Regulatory confidence with digital data that supports compliance and traceability. 

Engineering the Future, Digitally 

Digital solutions are no longer optional in medical device development — they are essential to competing in a fast-moving, high-stakes industry. By embracing simulation, visualization, and virtual testing, innovators can build smarter devices faster, with less risk and greater confidence. 

At Boston Engineering, our Digital Solutions COE brings the tools and expertise to make this possible. By integrating digital methods with our robotics, embedded systems, control systems, and DfX COEs, we create a digitally empowered systems engineering approach that accelerates innovation and ensures success. 

Whether you’re designing surgical tools, diagnostic platforms, or connected care devices, Boston Engineering can help you leverage digital solutions to reduce risk, accelerate development, and deliver devices that transform patient care.
