How to Approach a Challenging Design: The Creation of the World’s First Foldable PC

Christian Teismann, President, Commercial PC and Smart Device Business

In today’s always-on technological world, the roles between personal and professional devices are increasingly blurred. Users want devices that enable productivity, whether they’re in the workplace, in a coffee shop or simply at home. This need for flexibility and versatility in our technology has been the catalyst for the invention of the foldable PC category.

Creating an entirely new product category that delivers on constantly changing customer needs presents a myriad of challenges that require innovative and creative thinking, foresight, exceptional design and engineering expertise. While the process was one that took several years to perfect, solving for the complex challenges designing and engineering the world’s first foldable PC – the ThinkPad X1 Fold – into the hands of professionals was an incredible journey.

Identifying the white space for innovation

The ‘work from anywhere’ trend was on the rise years before COVID-19 completely altered the way we work. In 2019, IWG reported that 50 percent of employees globally were working outside of their main office headquarters at least 2.5 days per week. Knowing that the trend was only going to become more prevalent, Lenovo continued thinking about what the future of portable technology would look like.

One key area of innovation was flexible and foldable OLED displays, a market that is forecasted to grow by US$ 167.7 Billion by 2024. This sparked the PC concept of “carry small, use big” that led to the creation of a whole new device category with the introduction of the world’s first foldable PC.

Designing a solution for the impossible 

Once the need was identified, our focus shifted to ideation and design. The key to a successful design was thinking of the end user experience and identifying the key components the device must have, then developing a blueprint to bring those components to life. The challenge for the X1 Fold design team became how to combine the size and portability of a smartphone, the power and functionality of a business device and the flexibility missing in the current market, to deliver on all fronts.

The answer was the foldable screen!

Engineering to be part of the solution, not the problem

Upon first sketches in 2016 for the world’s first foldable PC, we entered the engineering phase where the creative vision is brought to life through technical architecture. Navigating engineering challenges required a diverse team that provided a variety of perspectives in order to effectively collaborate and develop solutions to deliver on what we once thought was impossible.

In the case of the ThinkPad X1 Fold, Lenovo and Intel engineering and sub-engineering teams collaborated tirelessly to engineer solutions around the device’s design, durability and usability. The main challenge was having all the system components fit within a very limited space, which was only compounded by the unique restrictions of the foldable mechanism.

The solution was found in a story of layers. Eleven layers to be exact—inclusive of the bezel, folding OLED screen made in collaboration with LG Displays, carbon fiber shutter frame, unique cooling system and foldable graphite.

While the OLED screen stands out, there is much more than meets the eye. Multiple layers underneath the screen allow users to fully experience the benefits of the folding technology.

What makes the ThinkPad X1 Fold truly foldable is the unique multi-link hinge, which was designed to protect the OLED screen when closed and provides the proper tension across the full range of motion, “pulling” the screen flat when fully opened. When combined, the layers and hinge create a positive user experience marked by durability. In addition to an unprecedented physical design, the ThinkPad X1 Fold also provides a new level of usability.

Understanding that users want an always on and always connected experience, the team designed the X1 Fold with speakers and six antennas for 5G and Wi-fi connectivity. To maximize cooling, our team in Yokohama, Japan took inspiration from Yosegi, a traditional Japanese mosaic woodworking, to create a revolutionary cooling system.

Tested for durability 

In the last phase before the product goes to market, the end user experience needed to be refined, which requires thorough rigorous testing to ensure usability, durability, quality and functionality.

Lenovo’s unique device was tested in accordance with Lenovo’s famed, yet closely guarded Yokohama approach, which pushes the limits of a device to ensure it meets or exceeds the durability legacy of the ThinkPad name. In the case of the ThinkPad X1 Fold, which pushes the boundaries of design and engineering, this was a crucial step before bringing it to market. With flexibility and foldability defining features of the product, the device was opened and closed minimum 30,000 times as part of this process to ensure the screen would maintain its integrity and functionality.

Bringing it to market

With such innovation and ingenuity behind it, the potential for the ThinkPad X1 Fold is unlimited. Pick an industry and there will undoubtedly be employees and sections of workforce that would benefit from a foldable computing device. Doctors and nurses will no longer be inconvenienced by size and weight as they travel from ward to ward, and designers can be on-set making real-time modifications to stage and lighting plans.

Creating a new product, yet alone a new product category is no easy feat. It requires ingenuity, creativity and brave new thinking. But customers need brands to meet those challenging design needs head on to further productivity and mobility within their lives. The creation of the ThinkPad X1 Fold just goes to show that with the right design approach, all things are possible.
