Organization

They offer a diverse range of products, including electrical smart meters, power amplifiers, and electronic circuits. The client partnered with Vee Technologies for comprehensive mechanical design solutions.

Challenges

Since clients with an electrical and electronics background seeking mechanical engineering support typically face challenges in areas outside their core expertise.

The major challenges included:

  1. Product Enclosure Design: Designing casings or housings for electronic components, with a need for effective thermal management solutions (e.g., heat sinks, airflow design).
  2. Prototyping & CAD Modelling: Requirement for 3D modelling and simulation of mechanical parts, along with rapid prototyping using CNC machining, 3D printing, or injection moulding.
  3. Material Selection: Guidance on selecting materials for strength, durability, and thermal properties, while ensuring compliance with standards such as RoHS and IP ratings.
  4. Manufacturing Support: Support for Design for Manufacturability (DFM) and Design for Assembly (DFA), including tolerance analysis and production drawings.

Solutions

The design process for developing a ‘plastic enclosure’ for smart meters involved several key stages:

  • Concept Sketching: Early-stage conceptual sketches illustrating product layout, component placement, and mechanical integration ideas.

  • CAD Modelling: Creation of parametric 3D models for enclosures. Material properties were applied, and mechanical behaviour was simulated.

  • Client Review & Iteration: CAD models were shared for feedback, and revisions were made based on usability, manufacturability, and aesthetics.

  • Injection Mold Analysis: Analysis of draft angles, wall thickness, and Mold flow to optimize part design for tooling and production efficiency.

  • Production Drawings: Generation of detailed 2D drawings with tolerances, surface finishes, and assembly instructions, ensuring compliance with industry standards and manufacturing capabilities.

Benefits

  1. Accelerated Product Development: Rapid concept visualization and sketching enabled quick validation of design ideas. The use of 3D CAD models in SolidWorks facilitated faster design iterations and significantly reduced the time to marketing.
  2. Improved Design Accuracy: Detailed CAD modelling ensured precise fit and alignment with electronic components. GD&T in production drawings minimized manufacturing errors and improved quality control.
  3. Enhanced Collaboration: Regular client reviews of CAD models promoted clear communication and reduced rework. Visual models helped non-mechanical stakeholders understand design intent.
  4. Manufacturing Readiness: Injection Mold analysis optimized parts for tooling, reducing production costs and defects. Production drawings supported a seamless transition from design to manufacturing.
  5. Cost Efficiency: Early detection of design issues through simulation and analysis saved time and resources. Streamlined DFM practices reduced material waste and assembly time.
