Industrial Design
Product character, wearing concept, proportions, CMF direction and brand intent
OUTPUTApproved design direction and review surfacesENGINEERING
Engineering support from concept to production.
Coordinate product definition, mechanics, electronics, firmware, acoustics and industrialization for programs that require more than catalog sourcing.
SYSTEM APPROACH
An earbud is one connected product system.
A change to housing, antenna space, battery, microphone path, controls or acoustic cavity can affect other disciplines. Engineering reviews these interfaces before the project commits to tooling or validation.
ENGINEERING DISCIPLINES
Six workstreams, one product definition.
The final scope depends on how far the project moves beyond an available platform.
Mechanical Engineering
Housing, fit, charging contacts, assembly, sealing and manufacturability
OUTPUTMechanical definition, tolerances and build issuesElectronics
Bluetooth platform, power, charging, microphones, controls and antenna integration
OUTPUTElectrical architecture and interface definitionFirmware
Pairing, controls, prompts, power states and supported feature behavior
OUTPUTVersion-controlled function definitionAcoustic Engineering
Driver, cavity, microphone path and tuning against the product target
OUTPUTTuning direction and measurable approval criteriaTooling & Industrialization
Mold feasibility, assembly process, fixtures, pilot readiness and production transfer
OUTPUTTooling release and production-control inputsINTERFACE REVIEWS
Resolve cross-discipline risks early.
These interfaces commonly drive redesign, sample iteration or validation work.
Fit × acoustics
Wearing geometry changes cavity, seal and perceived sound
Housing × antenna
Materials and internal layout affect wireless performance
Battery × mechanics
Capacity, thickness, weight and thermal behavior compete for space
Firmware × controls
Touch or button behavior must match hardware and user flow
Packaging × compliance
Labels, manuals, battery marks and market files must align
Tooling × assembly
Parting lines, tolerances, fastening and test access affect production
DECISION GATES
Review before the next investment.
Each gate checks whether requirements, design, risks and evidence are ready for the next stage.
