Camera Capabilities
As the designer who took over the LEX M20 project after the initial designer, Mark Palmer, left Motorola, I was involved from the early stages of development. Collaborating with engineers in Malaysia and Israel, we finalized the overall concept and details of the device. Our focus was on refining aspects such as the topcap, button ergonomics, display protection, assembly methods, and modularity. Additionally, we prioritized wearability and developed accessories like holsters and vehicle cradles. A key part of our work involved ensuring seamless audio routing between LTE and LMR, collaborating closely with the HF team to address usability issues effectively.

Legacy Design Elements
(Speaker / PTT / Buttons DNA)
Jawbone Form Factor for better grip
The design of the LEX M20 focuses on ergonomics, particularly for handling a larger device. To minimize its overall size while ensuring comfort, the perimeter around the battery is shaped to fit the hand, a feature known as the "jawbone design." This ergonomic focus is complemented by aesthetic continuity, as seen in the pill-shaped PTT button and the speaker, which are modern interpretations of elements from the legacy DL series, blending traditional design with a contemporary look.
ARCHITECTURE INNOVATION
CMF (Color Material Finish)
In the final design stages of the LEX M20, particular attention was given to the LED lighting and various affordances such as lanyard features and the audio jack. We also explored a range of Color, Material, and Finish (CMF) options suitable for military field use. These choices emphasized celebrating the device's IP68 features, highlighting its resilience and functionality in demanding environments. This focus on detail ensured that the LEX M20 was not only practical for military applications but also aesthetically aligned with its intended use.
