__ The Mission

Fixed charging plugs cannot support a commercial EV fleet that needs to move.

Tual needed to house a massive, rugged battery storage unit capable of surviving the rigors of the field. The uncompromising brief demanded a forkliftable, weatherproof enclosure featuring an integrated crash barrier and 1.2-tonne load support—all engineered inside an incredibly tight two-month window.

‍Not another static plug, but a mobile powerbank engineered for heavy-duty deployment.

__ The Insight

For a hardware startup establishing a new category, the equipment is the brand.

Industrial energy gear usually prioritizes basic utility, resulting in sterile "black boxes" that lack brand presence. Tual needed a distinct visual design language that communicated reliability and scale, balancing extreme structural integrity with an accessible form that felt like a premium commercial product.

‍If the infrastructure looks like an anonymous experiment, category trust is lost.

__ The Filament Effect

Bridging industrial design and heavy engineering to define a signature product silhouette.

Filament engineered a robust yet lightweight sheet metal enclosure that established the primary design language for Tual’s entire future product family. We produced detailed CAD models and production drawings, ensuring every weld and fold maximised safety, accessibility, and structural field performance.

Translating heavy-duty industrial constraints into a cohesive, scalable product family.

__ The Breakthrough

Delivering a fully engineered, commercial-quality 1.2-tonne prototype in just eight weeks.

We integrated a structural crash barrier and immense load support directly into a highly refined sheet metal architecture. This proved that heavy-duty infrastructure could be transportable and aesthetically premium, shifting a complex engineering challenge into a scalable, market-ready asset.

‍Compressing a massive industrial hardware timeline into a rapid eight-week launch.
