Innovating for Impact: The Power of Design Thinking

In this blog, we will explore the importance of design thinking and innovation, and the role of empathy, prototyping, and testing in the process. We will also look at some real-life examples of how these concepts have been applied in different areas such as product development, manufacturing process, materials development, and technology innovation. From the development of first mass-produced gasoline-electric – hybrid - car, the Toyota Prius, to the creation of sustainable materials such as bioplastics, we will see how design thinking and innovation can lead to solutions that truly meet the needs of the users.


Design thinking

Design thinking is a problem-solving approach that involves empathy, experimentation, testing, and iteration to reach creative solutions. It is often used in product and service design but can be applied to any type of challenge or prospect. Innovation refers to the process of creating new and improved products, services, or processes. Design thinking and innovation often go hand in hand, as the design thinking process encourages out-of-the-box thinking and experimentation, which can lead to new and innovative ideas. In this blog we will discuss:

  • The importance of empathy in the design thinking process,

  • The value of prototyping and testing,

  • And the need for a collaborative and iterative approach to problem-solving.

Empathy and design thinking process

Empathy is fundamental in the design thinking process. It is the ability to understand and share the feelings of others, and it is considered essential for creating solutions that genuinely meet the needs of the people who will be using them. Empathy can be used in many ways in the design thinking process as shown in the following.

  • Empathy mapping: Empathy mapping is the first step in the design thinking process. It is a technique used to understand the needs, wants, pain points, and behaviors of the users. It involves creating a visual map that outlines the user's thoughts, feelings, actions, and their areas of concern. This information can then be used to inform the designers and developers of a product or service, ensuring that their developed product or solution meets the needs of the user.

  • User research: There are basically two categories of user research: (i) qualitative research based on interviews of the potential users and/or stakeholders, (ii) quantitative research usually based on surveys to collect measurable data. Empathy is also essential in user research. By conducting user research, researchers and designers will reach a deeper understanding of the people they are designing for (end-users), and this will lead to the improvement of the design process. User research can take many forms, such as interviews, surveys, or ethnographic studies.

  • User-centered design: User-centered design is a design approach that puts the needs of the user at the center of the design process. By using empathy to understand the needs of the user, designers can create solutions that are tailored to the users’ needs which will be more likely to be accepted, considered as comfortable, and thus used in a successful way.

  • Empathy in testing: Empathy is also important when testing a product or service. By understanding the user's perspective, researchers can create more effective tests and gather more meaningful feedback. This feedback can then be used to improve the product or service, making it more user-friendly and effective.

The value of prototyping and testing

Testing and prototyping are both essential elements of the design thinking process. They allow teams to test their ideas and adjust before committing resources to a final solution in a quick and inexpensive manner.

On one hand, prototyping is the process of creating a preliminary version of a product or service. The goal of prototyping is to test the feasibility of an idea and to gather feedback from potential users. By creating a prototype, teams can see how their idea will work in the real world and make any necessary adjustments.

Testing, on the other hand, is the process of evaluating a product or service to see how it performs. This can include usability testing, where a product is tested with real users, or performance testing, where a product is tested under a variety of conditions. The goal of testing is to identify any issues or problems with a product or service, and to gather feedback on how it can be improved.

Both prototyping and testing are critical in the innovation and design thinking process, as they allow teams to make informed decisions about the development of their products and services. They also support them in identifying potential issues early on, which can save time and resources in the long run. By testing and prototyping, teams can be more confident that their final solution will meet the needs of their users and be successful in the market.

This approach based on prototyping and testing was followed and implemented in any known and used devices and solutions on the market, today. We can cite the examples of the Apple’s Phone, Google Maps, the Toyota Prius, etc. These examples show how testing and prototyping can lead to successful products and services and improve the final solution. It is important to remember that testing and prototyping are essential in the innovation and design thinking process, as they allow the teams to make informed decisions, and identify potential issues early on, which can save time and resources.

The need for a collaborative and iterative approach

A collaborative and iterative approach to problem-solving is a method in which a team of people work together to solve a problem or achieve a goal. This approach emphasizes the importance of working together and sharing ideas, as well as the value of testing and refining solutions.



Collaboration is key in this approach, as it allows for the assembling of diverse perspectives and skills, which can lead to more creative and effective solutions. By working together, team members can also provide support and feedback to one another, which can motivate the troupes and keep the project on track.

Iteration refers to the process of testing and refining solutions. This is a crucial step in the problem-solving process. Indeed, iteration allows for the identification of any issues or challenges related to a proposed solution. And it proposes and/or implements adjustments accordingly. By testing and refining solutions in an iterative manner, the researchers can ensure that their final solution is effective and efficient.

It's important to note that a collaborative and iterative approach to problem-solving is often cyclical, meaning that teams may return to earlier stages of the process as they continue to test and refine their solutions. This approach allows teams to continuously improve their solutions and adapt to new information or changing circumstances.

Real-life examples of developments based on design thinking

In the following, we will show some real-life examples of design thinking have led to successful products or services, and how it helped to improve the final solution. Our examples will mainly focus on the design thinking employment in materials manufacturing, and in biosensors development.

Design thinking in materials development

Many brilliant examples show how design thinking has been used to develop innovative and highly performant materials.

  • Graphene: Graphene is a two-dimensional material that was first isolated in 2004 by a team of researchers at the University of Manchester, UK. The team used design thinking and innovation to develop new techniques for isolating and studying graphene, which led to the discovery of its remarkable properties, such as high electrical conductivity, flexibility, and strength.

  • Aerogel: Aerogel is a lightweight, porous solid material looking like a gel in which the liquid phase is replaced by a gas. It was first developed in the 1930s by Samuel Kistler. Aerogel is an excellent insulator and has a wide range of potential applications, including insulation, filtration, and aerospace. The development of Aerogel was based on the iterative process, testing and prototyping until they find the best formula.

  • Bioplastics: Bioplastics are a type of plastic made from renewable biomass sources, such as corn starch, instead of fossil fuels. Bioplastics is an example of how design thinking and innovation can be used to develop more sustainable materials. Bioplastics development is driven by the need of finding sustainable alternatives to traditional plastics and the research and development groups and teams are using design thinking and innovation to come up with new ways to create bioplastics from various sources, such as sugarcane, cassava, and algae.

  • Carbon fiber: Carbon fiber is a strong, lightweight material made from carbon atoms. It's widely used in aerospace, automotive, and sports equipment industries.
