I led the industrial design of the Ember Travel Mug through a focused, user-centered process that balanced emotional appeal, engineering constraints, and manufacturability.

Research and problem definition

• Contextual inquiry: Observed and interviewed commuters, travelers, and office workers to understand routines, pain points, and how they interact with beverage containers across environments (car, transit, desk, outdoors).

• Competitive analysis: Mapped features, materials, and form languages of existing travel mugs and smart drinkware to identify gaps in usability, thermal performance, and aesthetics.

• Design brief: Defined objectives: maintain beverage temperature for extended periods, minimize spills, support one-handed use, integrate intuitive controls for temperature, and deliver a premium, durable appearance suitable for daily use.

Concept development

• Ideation workshops: Ran sketching and rapid-prototyping sessions with cross-functional stakeholders (engineering, materials, UX, product management) to explore form factors, lid mechanisms, and control layouts.

• Prioritization: Used feasibility-impact scoring to narrow concepts to those that balanced core performance (thermal behavior, leak resistance) with manufacturability and cost targets.

• Storyboards and use-cases: Visualized real-world scenarios (morning commute, conference table, car cup holder) to ensure form and features addressed primary user contexts.

Industrial design and ergonomics

• Form language: Iterated shapes to create a silhouette that reads premium and is easy to grip. Considered taper, diameter, and surface finishes to fit common cup holders while enabling one-handed manipulation.

• Ergonomics: Prototyped multiple grip geometries and lid actuation forces. Tuned button placement and tactile feedback for intuitive operation without visual confirmation.

• Material selection: Selected exterior materials and finishes to balance scratch resistance, thermal insulation, and tactile warmth. Coordinated with engineering on interior coatings and sealing materials compatible with electronics and heating elements.

Prototyping and testing

• Rapid prototypes: Produced 3D-printed shells and soft-touch overlays for early usability testing. Created functional prototypes integrating heating elements and battery packs to validate thermal performance and weight distribution.

• Usability testing: Ran iterative tests with representative users to evaluate grip comfort, lid sealing, one-handed operation, and cleaning. Observed failure modes (lid leakage under tilt, button mis-press) and fed findings back into design adjustments.

• Thermal and durability testing: Partnered with engineering to run thermal retention tests, cycle testing for seals and hinges, and drop tests to ensure the design met durability targets without excessive material thickness.

Engineering collaboration

• Design for manufacture: Worked closely with mechanical and electrical engineers to refine internal packaging of heating elements, battery, and PCB while preserving the exterior proportions and user experience.

• Tolerancing and assembly: Iterated on snap-fit features, sealing interfaces, and screw bosses to simplify assembly and improve reliability. Balanced cosmetic gaps with assembly repeatability.

• Regulatory and safety: Integrated insulation and safety interlocks so the product met electrical and safety standards while preserving ergonomics.

Finalization and production support

• Surface finishes and branding: Specified colorways, soft-touch coatings, and subtle brand treatments to achieve a premium, understated aesthetic consistent with the product family.

• Pilot run and QA: Supported pilot production, reviewed first articles, and resolved cosmetic and functional issues discovered during initial manufacturing runs.

• Documentation: Delivered finalized CAD, assembly drawings, and specifications for tooling along with style guidance for marketing imagery.

Outcome The final Ember Travel Mug combined thoughtful ergonomics, reliable thermal performance, and a refined material expression.
