1. Objective
The objective of this stage is to apply advanced sketch editing, constraint, and feature tools in SolidWorks to design and refine the structural components of a portable water purifier. This process ensures precision, functionality, and manufacturability in the 3D model under the supervision of our instructor.
2. Summary of Learning
In this research session, our team explored advanced sketching and feature tools in SolidWorks. We practiced using Trim Entities, Extend Entities, and Offset Entities to edit and adjust sketches efficiently. In addition, we applied Geometric Relations such as Parallel, Perpendicular, Tangent, and Equal to fully constrain sketches and maintain dimensional accuracy after modifications.
We then learned to use the Extrude Cut feature to remove material from solid models, creating holes, slots, and internal cavities—essential elements for pipe connectors and filter housings in the purifier. Important precautions were emphasized, including selecting the correct sketch plane, verifying cut direction, and avoiding undesired intersections between components.
Furthermore, we studied key Feature Tools such as Hole Wizard, Chamfer, and Fillet. The Hole Wizard enabled the creation of standardized screw holes for consistent assembly alignment, while Chamfer and Fillet enhanced both functionality and aesthetics by removing sharp edges and improving surface transitions.
3. Application to Water Purifier Design
These tools were directly applied to the development of the purifier’s main structure. Advanced sketch editing and constraint commands helped refine the designs of the connecting pipes and filter holders, ensuring geometric precision. The Extrude Cut tool was used to create internal flow passages and openings, while the Hole Wizard provided accurate placements for screws used in frame assembly.
Additionally, Chamfer and Fillet features were implemented to improve mechanical durability, user safety, and maintenance convenience by eliminating sharp or fragile edges.
4. Conclusion
Mastering advanced sketching and feature tools in SolidWorks is essential for producing accurate, manufacturable, and realistic 3D components. Through this stage, our team strengthened its technical ability to translate design intent into functional solid models. These skills form the foundation for prototype fabrication and ensure that all parts meet the structural and functional standards required for the Eco Filter Project.
5. Next Step
Our next phase will focus on Assembly Tools in SolidWorks, where all designed parts will be integrated into a complete 3D assembly for mechanical testing, motion simulation, and visualization of the final portable water purifier.
