A detailed look at the differences between the two roles - for engineering freshers new to the industry
Large product development organizations generally follow the systems engineering approach.
That is , for each system , sub system and component there are system engineers.
The system engineers are design engineers responsible for the delivery of the systems in the project and should take full ownership of the design and take care about all aspects of their system from conceptualization to production.
System engineers work along with simulation experts or CAE team to evaluate detailed designs using virtual validation methods.
CAE engineers are specialists in specific areas.
For example in the case of Automotive engineering , CAE engineer might be into durability, NVH , crash or dynamics . Each of these teams have specialized competencies to evaluate and improve designs as per their domains in those specific areas.
Design engineers are required to know the overall aspect of the product design in terms of concept development, manufacturability, change management, Issue resolution, failure analysis , serviceability etc, whereas CAE engineers are focused on simulation and making the design better through Virtual validation .
Mechanical design engineers are responsible for creating detailed designs based on product specifications, user requirements, and engineering principles. They work on CAD (Computer-Aided Design) software to create 3D models and drawings
The role of the Design engineer is central to integration of all requirements into one design whereas Simulation (CAE) engineer works with the design engineer on only the simulation aspect.
The roles maynot be the same across all companies though depending on work load.
A Mechanical Design Engineer and a CAE (Computer-Aided Engineering) Engineer play distinct roles within the broader field of mechanical engineering for product development.
Here's a breakdown of the key differences between these two roles:
Mechanical Design engineer:
Mechanical Design Engineers primarily focus on the conceptualization, creation, and development of mechanical components, systems, and products. They are involved in the early stages of the product development lifecycle.
Conceptualization and Innovation Design engineers often engage in conceptualization and innovation to create new products or improve existing ones. They consider factors such as functionality, aesthetics, materials, and manufacturing processes.
Prototyping and Testing : Mechanical Design Engineers are often involved in creating prototypes and conducting preliminary tests to validate the feasibility and functionality of the design. This phase helps identify potential issues before mass production. Developing Proof of concept prototypes to test a new mechanism or a new structure.
Cross functional teams : Collaboration with cross-functional teams, including manufacturing, materials, and electrical engineers, is common. Design engineers need to ensure that their designs are feasible for production and align with overall project goals
Design for manufacturing : Considering manufacturability and ease of production is a key aspect of the mechanical design engineer's role. Designs need to be practical for mass production while meeting quality standards. Setting tolerancing schemes and Making engineering drawings which clearly convey design intent.
Computer-Aided Engineering Engineer:
CAE Engineers primarily focus on the virtual testing, simulation, and analysis of mechanical designs using specialized software tools. They work to optimize designs, ensure performance, and identify potential issues before physical prototypes are built
CAE Engineers perform simulations and analyses on various aspects of a design, including structural integrity, thermal performance, fluid dynamics, and other physical behaviors. Using numerical methods and mathematical models to predict and optimize performance.
Virtual testing : CAE Engineers conduct virtual testing to assess how a design will behave under different conditions and loads. This helps in identifying potential weaknesses, optimizing designs for performance, and reducing the need for physical prototypes. Before investment into costly prototypes, designs can be validated with a click of a button .
Optimization The goal of a CAE Engineer is often to optimize designs for efficiency, cost-effectiveness, and performance. They may perform sensitivity analyses to identify critical design parameters and make informed decisions.
Risk Mitigation By identifying and addressing potential issues through simulations, CAE Engineers contribute to risk mitigation. This can lead to more robust and reliable products, reducing the likelihood of design flaws in the final physical prototypes.
Collaboration CAE Engineers collaborate closely with design engineers to integrate simulation results into the design process. Their insights help refine and improve designs based on the analysis of virtual prototypes.
while Mechanical Design Engineers focus on the creative and physical aspects of bringing a product to life, CAE Engineers specialize in using advanced simulation tools to analyze and optimize designs virtually. Both roles are integral to the product development process, working collaboratively to ensure that the final product meets performance requirements, is manufacturable, and is free from critical design flaws.
