This collection showcases a variety of smaller design projects that demonstrate versatility in applying engineering principles and creative problem-solving across different domains. Each mini-project represents a unique challenge that required specific technical skills and innovative thinking to address.
From conceptual sketches to detailed CAD models and functional prototypes, these projects highlight the ability to take ideas from initial concept through to implementation. The collection spans mechanical designs, consumer products, and specialized tools, illustrating a comprehensive approach to design that considers functionality, aesthetics, and manufacturability.
Designed and built a scale model of the solar system with accurate relative planet sizes and orbital distances. The project began with detailed sketches to establish proportions and mechanical requirements, followed by CAD modeling to refine the design. The final implementation features a stable base with precisely positioned planet models, creating an educational display that effectively communicates the scale of our solar system.
Developed a mechanical walking robot that translates rotational motion into a stable walking gait. The design incorporates a linkage system that mimics biological leg movement, creating a smooth and efficient locomotion mechanism. The project progressed from initial concept sketches through detailed CAD modeling to a functional prototype that successfully demonstrates the walking principle. The final implementation uses durable materials and precision-engineered joints to ensure reliable operation.
Designed a versatile storage cabinet system with modular components that can be configured to meet various storage needs. The design features adjustable shelving, specialized compartments, and a sliding drawer mechanism for efficient space utilization. Particular attention was paid to material selection, structural integrity, and ease of assembly. The CAD model includes detailed specifications for manufacturing, with consideration for cost-effective production methods.
Created a comprehensive set of technical drawings for a precision component, demonstrating proficiency in engineering documentation standards. The drawing set includes detailed views, dimensions, tolerances, and material specifications necessary for manufacturing. Special attention was given to GD&T (Geometric Dimensioning and Tolerancing) to ensure the component's functional requirements would be met during production. The drawings follow industry standards and include all information required for quality control and inspection.
Each mini project begins with a clear definition of the problem to be solved or the need to be addressed. This involves identifying key requirements, constraints, and success criteria that will guide the design process. For these projects, I focused on understanding the core functionality needed while considering factors like usability, manufacturability, and aesthetic appeal.
Initial ideas are explored through hand sketches that allow for rapid iteration and creative exploration. These sketches focus on overall form, key features, and potential mechanisms without getting bogged down in details. The sketching phase is crucial for generating multiple approaches and identifying the most promising directions for further development.
Selected concepts are developed into detailed designs using appropriate CAD software. This phase involves precise modeling of all components, consideration of materials and manufacturing methods, and refinement of mechanisms and features. The CAD models serve as virtual prototypes that can be evaluated and improved before physical production.
For many of these projects, physical prototypes were created to validate the design and identify any issues not apparent in the digital models. Prototyping methods varied based on project requirements, from 3D printing to traditional fabrication techniques. Each prototype provided valuable insights that informed design refinements.
The final step involves creating comprehensive documentation of the design, including technical drawings, material specifications, and assembly instructions where applicable. Presentation materials are also developed to effectively communicate the design intent, features, and benefits to stakeholders or audiences.
