Diagnostics Reimagined: Accuracy, Speed, and Usability

Diagnostics at the Core of Modern Healthcare 

Diagnostics are at the center of healthcare decisions. From identifying disease at its earliest stage to guiding treatment strategies, diagnostic devices provide the information clinicians rely on to act quickly and confidently. 

For executives at medical device companies, the challenge is clear: diagnostics must be accurate, fast, cost-effective, and easy to use. In practice, this means integrating precision engineering with user-centered design and manufacturing foresight. Without this combination, even promising diagnostic innovations can face adoption hurdles or scale-up failures. 

At Boston Engineering, we specialize in transforming diagnostic technologies into reliable, scalable, and user-friendly products. By integrating our Centers of Excellence (DfX, Embedded Systems, Robotics, Digital Solutions, and Control Systems) with systems engineering discipline, we help innovators deliver diagnostics that succeed both in the lab and in the marketplace.

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)

Case Example 1: Diagnostic Consumable Redesign

A client had a single-use diagnostic consumable that worked in principle but was too costly and complex to manufacture at scale. Without redesign, commercialization was out of reach. 

Boston Engineering applied its DfX expertise to: 

• Simplify the assembly process by reducing part count and steps. 

• Optimize material selection for cost, biocompatibility, and performance. 

• Conduct usability testing to ensure the consumable was intuitive for clinicians. 

• Align the design with scalable manufacturing methods. 

Outcome: The consumable became reliable, cost-effective, and manufacturable at high volumes, enabling successful scale-up without sacrificing performance.

Case Example 2:  Point-of-Care Testing Device

Another innovator was developing a portable point-of-care diagnostic tool for use outside of traditional labs. While technically promising, the prototype was fragile, difficult to use, and not optimized for reliability in diverse environments. 

Boston Engineering helped by: 

• Redesigning components for ruggedness and reliability under real-world conditions. 

• Incorporating human factors engineering to make the device intuitive for busy clinicians and technicians. 

• Streamlining assembly for manufacturability and serviceability. 

• Conducting early-stage stress testing to validate performance in field conditions. 

Outcome: The point-of-care device achieved greater durability, usability, and reliability, making it practical for widespread adoption and clinical confidence. 

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.

Case Example 3: Automated Diagnostic Instrument

A diagnostic company needed to automate a traditionally manual laboratory test to improve speed, consistency, and throughput. The challenge was creating a system that delivered high repeatability while reducing the risk of human error. 

Boston Engineering delivered by: 

• Designing robotic automation to handle samples with precision and consistency. 

• Integrating embedded electronics and control systems to coordinate motion and sensing. 

• Applying simulation and digital tools to optimize workflows before building physical prototypes. 

• Ensuring scalability by designing for future expansion in sample capacity. 

Outcome: The automated instrument achieved significant improvements in speed and repeatability, reducing variability and freeing up clinical staff for higher-value tasks. 

The Common Thread: Smarter, Faster, More Usable Diagnostics 

Across consumables, point-of-care tools, and automated instruments, the key to success wasn’t just technical feasibility. It was designing for the realities of manufacturing, usability, and adoption. 

Boston Engineering ensures that: 

• Accuracy is built into the design through precision engineering and robust control. 

• Speed is accelerated through automation and streamlined workflows. 

• Usability is prioritized so clinicians can operate devices confidently in demanding environments. 

• Scalability is achieved by applying DfX principles from the earliest stages. 

This holistic approach enables diagnostics to move from promising prototypes to trusted clinical products. 

Diagnostics Designed for Real-World Impact 

In today’s healthcare environment, diagnostic innovation must balance accuracy, speed, cost, and usability to succeed. For executives, that means choosing a partner who understands not only how to engineer precision systems, but how to deliver them as complete, market-ready products. 

Boston Engineering has done this across consumables, point-of-care devices, and automated instruments. By combining deep engineering expertise with program management, regulatory awareness, and systems discipline, we help innovators deliver diagnostics that clinicians trust and patients rely on. 

When you partner with Boston Engineering, you gain more than a product development firm — you gain a team committed to making sure your diagnostic innovation delivers real-world clinical impact at scale.
