Design & Research Strategy and Product Requirements Definition.
D4C Product Development is a San Diego-based engineering and product development practice that guides hardware products from concept to market. It integrates mechanical, electrical, and software engineering with industrial design, prototyping, and manufacturing support, serving consumer electronics, IoT devices, environmental technology, and public safety markets.
Data-driven product strategy spanning the full product lifecycle, from problem identification and requirements definition through design, development, and market deployment.
Documenting technical specifications, user requirements, and regulatory or safety standards that a product must meet before design begins.
Ideation, concept development, and product architecture planning aligned to market opportunity and functional objectives.
Defining product goals for functionality and market impact, with a roadmap from conception through commercial release.
Full-cycle mechanical engineering for hardware products, from concept design through manufacturing support.
Ideation, concept development, product architecture, and mechanical requirements development.
3D CAD design with material selection, DFMA for high-volume production, injection-molded part design, sheet metal design, custom cable and connector design, UL/CSA requirements, and packaging design.
Stress analysis, finite element analysis (FEA), thermal analysis, designed experiments, design optimization, and manufacturing tolerance stack-up analysis.
Physical prototypes via FDM, SLA, and SLS additive manufacturing processes and sheet metal fabrication.
Engineering drawings, assembly instructions, detailed BOMs, manufacturing process development, production tooling development, and supply chain sourcing.
Develops consumer electronics and IoT electrical systems from schematic design through compliance verification and firmware support.
Schematic drawing, component sourcing and benchmarking, printed circuit board design, and DFMA for high-volume electronics.
FCC electrical compliance, EMC analysis, ESD analysis reports, and CDVA reports for existing designs.
