Medical Device Development Insights: Design Thinking in Medical Device Innovation

This article is part of ATL’s Medical Device Development Insights series, which explores the engineering processes used to bring safe, effective medical devices from concept to market.

Overview

As discussed in our previous article on Human Factors Engineering and Design Thinking, combining structured usability engineering with user-centered problem discovery allows teams to develop medical devices that meet both regulatory requirements and real-world user needs.

In this article, we take a closer look at Design Thinking—what it is, how it works, and how it can be applied within medical device development to support innovation.

Innovation is not a sudden moment of insight. It emerges through a structured, iterative process. While design is often associated with aesthetics, Design Thinking is a human-centered approach to problem-solving that is highly relevant to engineering teams in MedTech.

At its core, Design Thinking emphasizes understanding users and rapidly exploring solutions. It relies on abductive reasoning—forming hypotheses based on observations—to navigate complex and uncertain design challenges.

To better understand how Design Thinking supports innovation in practice, it is helpful to break down its structure.

The Design Thinking Process

Design Thinking is typically structured as a series of iterative, collaborative phases—often represented as a continuous loop rather than a linear sequence—in which teams continuously refine their understanding of user needs and potential solutions.

The Five Phases

1. Empathize: Focus on understanding users, their environments, and their experiences.
2. Define: Translate observations into a clear and actionable problem statement.
3. Ideate: Generate a broad range of potential solutions through structured brainstorming.
4. Prototype: Create early representations of ideas to explore feasibility and usability.
5. Test: Evaluate solutions through user interaction and feedback, refining designs iteratively.

While these phases provide a structured framework, their real value becomes clearer when applied within engineering-driven development environments.

Design Thinking in an Engineering-Driven Environment

In practice, Design Thinking often begins with collaborative workshops that bring together engineering, clinical, and design perspectives.

Design Thinking is not limited to traditional design roles. It provides value across the entire product development team, including engineers responsible for system architecture, mechanical design, and device functionality.

Design Thinking helps engineers make more informed decisions around system architecture, user interaction, and workflow integration, particularly when requirements are still evolving.

When integrated into the development process, Design Thinking can support:

• Innovation Beyond Constraints: Encourages teams to explore solutions beyond immediate technical limitations, leading to new approaches that may not emerge from constraint-driven design alone.
• User Alignment: Ensures that product decisions are grounded in real user needs, rather than assumptions made during early requirements definition.
• Iteration Efficiency: Supports rapid prototyping and early testing, helping teams identify issues sooner and reduce downstream rework.
• Cross-Functional Collaboration: Facilitates collaboration between engineers, clinicians, and other stakeholders, improving communication and alignment across disciplines.

Where Design Thinking Fits in Medical Device Development

Design Thinking is most visible during early-stage development, but its principles can be applied throughout the entire design and development lifecycle.

• Concept Phase: Used to explore user needs, observe clinical workflows, and define the problem space.
• Design & Development Phase: Supports iterative design through prototyping and user feedback, helping teams refine concepts before committing to detailed engineering.
• Verification & Validation: Helps ensure that developed solutions align with real-world workflows and user expectations, complementing formal usability validation activities.

A practical example helps illustrate how these principles translate into real-world outcomes.

Case Study: Applying Design Thinking in Healthcare

A well-known example of Design Thinking in healthcare is GE Healthcare’s “Adventure Series” MRI.

The Problem

Designer Doug Dietz observed that the clinical environment surrounding MRI systems created significant anxiety for pediatric patients. This often led to the need for sedation, increasing both cost and complexity.

In this case, the primary challenge was not the imaging technology itself, but the patient experience created by the surrounding clinical environment.

The Approach

By focusing on the patient experience, the team reframed the problem and explored ways to reduce fear. Instead of modifying the device alone, they redesigned the entire interaction environment.

The Solution

MRI suites were transformed into themed environments, such as pirate ships or space adventures, making the experience more engaging for children.

By redesigning the environment around the MRI system, the team addressed a user-centered problem that directly impacted both patient experience and clinical efficiency.

The Outcome

At one hospital, sedation rates were significantly reduced, improving both patient experience and operational efficiency.

While the core imaging technology remained unchanged, the redesign of the user experience significantly improved how the system was used in practice—demonstrating how non-technical factors can directly influence device effectiveness.

While this example highlights the impact of Design Thinking, it is also important to clarify how the methodology is sometimes misunderstood in technical environments.

What Design Thinking Is Not

Design Thinking is sometimes misunderstood as a purely creative or non-technical activity.

It is not:

• A replacement for engineering rigor
• A substitute for requirements or design controls
• Limited to industrial or visual design roles

Instead, it is a structured approach that helps teams define better problems and explore more effective solutions before committing to detailed design.

Understanding these distinctions makes it easier to begin applying Design Thinking in a practical, engineering-focused way.

Getting Started with Design Thinking

Design Thinking does not require a complete overhaul of existing development processes. Teams can begin incorporating its principles through small, practical steps:

• Engage directly with users to understand workflows and pain points
• Facilitate structured workshops to encourage idea generation
• Prototype and test early to evaluate concepts and refine direction

For further reading, foundational texts such as The Design of Everyday Things by Don Norman and Change by Design by Tim Brown provide additional context on Design Thinking principles and application.

Conclusion: Applying Design Thinking in MedTech

Design Thinking provides a structured approach to understanding user needs and exploring potential solutions within medical device development.

By integrating Design Thinking into engineering workflows, teams can improve how they define problems, evaluate concepts, and iterate on designs.

When used alongside Human Factors Engineering, Design Thinking helps ensure that innovation is grounded in real user needs while maintaining a focus on safety and usability.

The insights generated through Design Thinking can then be validated through Human Factors Engineering, ensuring that early concepts translate into safe and effective device use.
