Process Overview

The Lenovo Ergonomic Mouse goes beyond the norm and delivers an experience that replicates the natural form of a handshake with a 45° palm grip and revised finger positioning for optimal posture and productivity.

Development began with concept sketching and a broad range of forms in clay. Using ergonomics data as a basis, shapes were explored that were minimal enough to be universally appealing and not “over-fit” to one particular hand size or method of grip. Several promising clay models were refined and iterated in foam versions, where nuances of surfacing and part breakup were easier to express.

3D Scans

After obtaining confidence in a refined selection of foam models, we could transition into CAD. 3D scans were performed from the hand-sculpted foam models, resulting in data suitable to guide design on the computer. The scan data, while not directly useable for manufacturing, acts as an underlay overtop of which I could rebuild and refine the shapes to the level of perfection needed.

Surfacing Challenge

Having refined the design within CAD, we produced several 3D prints to validate our work. Final tweaks of the printed models then informed updates to the CAD. This iterative cycle of physical models and design work was a critical feedback process for a product so fundamentally hands-on. Early manufacturing strategies and part-breakup strategies were developed, and defined button layout and proportions. The final design orients the hand in an ergonomically-beneficial neutral position, which also invites the user’s touch with recycled injection-molded cork.

CMF

As objects with heavy daily use, a mouse and keyboard must above all be comfortable. Considered materials selection is key to rewarding this constant interaction. The Lenovo ergonomic mouse and keyboard utilizes injection-molded cork with recycled content that has a uniquely warm and relatable touch. It’s easy to clean, thanks to the liquid and UV resistant coating. As a capstone to the project, visual models of both designs were made in these materials to express both the aesthetic and tactile pleasures of the designs. A light and dark CMF provide versatility within the existing Lenovo product portfolio.

Ergonomic Keyboard | Process Overview

Development of the keyboard occurred in parallel with the mouse. Being also a very physical object with sensitive ergonomic requirements, the keyboard began with physical mockups as well. However, unlike the mouse, which involved several phases of hand-made models, the keyboard moved faster into CAD. After creating rough block models that appropriately balanced utilization of space and ergonomic factors, layouts could be developed on the computer.

Numpad Storage

Inherent with ergonomic keyboards is increased use of precious desk space. A wireless numpad was designed that stows beneath the tented center portion of the keyboard. This solution reduces the footprint of the keyboard on the desk and allows for custom placement of the numpad to whichever position the user desires
