Engineering Design Process

JLN Engineers applies a structured, iterative design process that translates identified needs into functional objectives, performance requirements, and practical engineering solutions. The process integrates background research, ideation and invention, engineering analysis, concept selection, design optimization, and detailed design. Materials, manufacturing methods, assembly, serviceability, cost, and applicable requirements guide the evaluation and refinement of alternatives, with calculations, simulation, and testing used as appropriate to verify performance.

The process is iterative. Optimization feeds back into engineering analysis, and findings may require revisiting earlier objectives, requirements, or concepts. Activities are tailored to the project scope.
  1. Identification of Need

    Record the need and intended use before prescribing a technical solution.

  2. Background and Research

    Investigate relevant technologies, operating conditions, prior solutions, and applicable requirements.

  3. Goal Statement

    Define what the solution must accomplish without prematurely selecting a physical arrangement.

  4. Performance Specifications

    Establish measurable requirements and constraints against which alternatives can be evaluated.

  5. Ideation and Invention

    Develop alternative concepts and arrangements to satisfy the defined functions and requirements.

  6. Engineering Analysis

    Evaluate the behavior and feasibility of concepts using calculations, simulation, and other appropriate methods.

  7. Concept Selection

    Compare alternatives against documented criteria and select a concept for further development.

  8. Design Optimization

    Refine design variables against defined objectives and constraints; repeat analysis and comparison as needed.

  9. Detailed Design and Verification

    Develop the selected design, drawings, and specifications; verify performance through appropriate analysis, inspection, or testing.
