Oven Convection System

Developed and optimized a high-performance convection system for a consumer oven, increasing airflow efficiency by 170% through innovative design and iterative testing. As my first project at SharkNinja, while I can’t disclose all details or share specific images, I’m excited to showcase the engineering insights and learnings from this experience.

Project Overview:

System Development: Led the development and testing of a convection system for a new oven, meeting executive-defined performance goals

Modifications: Researched, designed, and implemented changes to optimize airspeed distribution within the oven cavity

Performance Improvement: Increased overall airspeed by 170%

System Design & Development:

Component Selection: Selected and integrated a new motor and fan combination to enhance convection performance

Custom Fabrication: Designed and fabricated a custom radial shield and fan shroud to optimize airflow distribution across the cavity

System Modification: Modified an existing oven unit, disassembling and reassembling components to accommodate new design improvements

Modifying the existing Oven Unit to Implement a Custom Fan Shroud

Initial Protype for custom fan shroud

Testing and Data Collection:

Iterative Testing: Developed and executed a testing plan using candlestick anemometers to capture precise airspeed readings throughout the cavity

Sensor Arrays: Designed and implemented sensor arrays to monitor airflow in different regions, systematically collecting data to assess modifications

Flow Visualization: Conducted visual airflow tests using foam balls to track directional flow patterns, complementing anemometer data that provided airflow magnitude

Data Analysis:

Airspeed Mapping: Collected airspeed data from 18 anemometers to create a detailed airflow map of the oven cavity

Dead Spot Identification: Analyzed the data to identify low-flow "dead spots" and areas of inefficient airflow distribution

Data-Driven Modifications: Used the airflow map to guide design adjustments, iterating on physical changes to optimize airspeed and reduce dead spots

Collaboration & Communication:

Global Collaboration: Worked with teams in the US, UK, and China to ensure alignment on project goals, testing procedures, and deadlines

Management Updates: Provided weekly progress updates to upper management, clearly presenting technical findings and next steps

Design Documentation: Documented final design modifications in a detailed report for accurate implementation into the next prototype build


Project Reflection:

This was my first major project during my internship at SharkNinja. While I’m unable to disclose all project details or share specific images, I wanted to highlight the engineering and learning involved. It’s exciting to know that in the near future, a mass-produced consumer product will be on the market, and I played a significant role in its performance and quality.
