Kehinde J.

I help design and develop consumer and hardware products, engineer mechanical systems, and reconstruct existing components into accurate, manufacturable designs backed by practical engineering and documentation.

From early concepts and working prototypes to legacy components and existing products, my work focuses on the engineering decisions that determine whether a design can be manufactured, assembled, inspected, and used as intended.

With more than 12 years of experience in product development and manufacturing across a variety of industries and processes, I bring a practical understanding of how engineering decisions affect tooling, production costs, supplier execution, quality, and product performance.

CORE SERVICES

■ PRODUCT DESIGN & DEVELOPMENT

◦ Concept development and product design from ideas, sketches, photographs, or reference products.
◦ Mechanical engineering, 3D CAD development, and prototype design.
◦ Patent-Informed Design Alternatives: Explore alternative product architectures, mechanisms, and features informed by existing patents and prior art, with appropriate IP review where necessary.

■ NPI & MANUFACTURING READINESS

◦ Design for Manufacturing and Assembly (DFM/DFA):
Identify design changes that improve manufacturability, simplify assembly, and create opportunities to reduce production costs.
◦ Supplier & Factory Alignment:
Align engineering requirements and manufacturing documentation with supplier capabilities, process limitations, and achievable tolerances.
◦ Production Readiness & Risk Assessment:
Identify design, tooling, assembly, and quality risks before manufacturing release, with practical mitigation and verification measures.

■ ENGINEERING DRAWINGS, GD&T & TOLERANCE ANALYSIS

◦ Production drawings and geometric dimensioning and tolerancing (GD&T) to ASME Y14.5 or applicable ISO GPS standards.
◦ Worst-case and statistical tolerance stack-up analysis, where appropriate, to assess fit, interchangeability, and assembly risk.
◦ Coordinated CAD models, drawings, specifications, and inspection requirements to support consistent manufacturing and quality control.

■ MECHANICAL ENGINEERING & FEA

◦ Structural, modal, and thermal simulation, selected according to the engineering problem and applicable assumptions.
◦ Material and geometry optimization to evaluate opportunities for weight reduction, improved performance, and lower material or manufacturing costs.
◦ Engineering calculations, failure-risk assessment, and verification planning to support defensible design decisions.

■ REVERSE ENGINEERING & SCAN-TO-CAD

◦ Editable, parametric CAD reconstruction from 3D scans, physical-part measurements, and available reference data.
◦ Legacy Component Reconstruction & Redesign: Reconstruct obsolete or undocumented parts and adapt designs to current materials, manufacturing processes, or functional requirements.
◦ Engineering models and supporting documentation prepared for tooling, machining, fabrication, and inspection.

WHAT IT’S LIKE TO WORK TOGETHER

You don’t need to define every engineering step before we begin. I’ll establish the next steps, take ownership of the agreed work, and provide weekly updates while keeping you involved in key technical decisions.

INDUSTRIES & MANUFACTURING EXPERIENCE

My experience spans industrial equipment, medical devices, hand tools, production tooling, power transmission systems, and injection-molded products.

My practical manufacturing background includes work in foundries, machine shops, traditional, and CNC machining, fabrication, assembly, inspection, and quality control. I have also worked with manufacturing suppliers across China, Taiwan, Vietnam, the US, and Europe.

This experience informs my approach to design feasibility, process selection, tolerancing, supplier communication, and the transition from engineering development to manufacturing.
