Dell Latitude 3540

Dell Latitude 3540

15" Laptop (ODM project)

Duration: 11 months

Process: RFQ to tooling kicoff

Brand: Dell

Work at: Wistron

In this project, I am responsible for the ID/ME work. Working closely with Dell ADC, we took the initial ID concept all the way through to a production-ready design. Internally, I've collaborated closely with Wistron's cross-functional teams to translate Dell ADC's design concept into a production-ready model. Through our joint efforts, we've achieved a seamless balance between quality and ideal specifications. The resulting laptop features a bare plastic housing that not only maintains its aesthetic appeal but also prioritizes cost-effectiveness and environmental friendliness.

Laser etching texture

Even though the Dell Latitude 3540 is targeted as an entry-level laptop within the product line, no compromises were made in terms of design. The finish on the A and D covers features a customized texture from Dell. To achieve this specific visual effect, we avoided traditional chemical texturing and instead opted to laser-etch the custom texture onto the mold surface. The depth and area of the texture specs had to be precisely defined before applying to the mold surface.

Class A surface modeling

One of the most challenging aspects of this project was engineering under high-quality surface requirements. With bare plastic for the CMF, any defect from 3D modeling would result in a very serious, unfixable issue on the ID surface once tooling is created.

Design validation - Prototyping

During the design process, we've created several prototypes to compare and validate different versions of the design (13", 14" and 15"). Additionally, we've utilized a special painting technique to simulate the visual and tactile feel of the customized texture, which will be laser etched onto the mold during the tooling stage
