Here's how you can effectively identify and analyze design issues as a CAD designer.

understanding the software's capabilities and limitations is crucial for identifying design issues. Familiarize yourself with the tools and features available within your chosen CAD program.Ability to create different views and cross-sections to examine internal structures and ensure that all parts fit together as intended. It's also beneficial to compare your model against the original design

The real-world problems can be easily observed, visualized, replicated, simulated and analyzed using CAD easily. A kid starting from school days must learn CAD to contribute soulful solutions to the society which we professionals think much complex for solving issues of their age group. CAD when is used by professionals is giving professional solutions, when used by researchers gives scientific solutions Imagin what will happen if it is used by kids, edged people or social activists.... all must get trained to do CAD and solve issues using technical people's guidance. This will contribute more to the society. Challenges to be attempted, will be using professional brains just to improve the solutions not to earn but to contribute, socially.

Understanding the initial design is one of the keys to success as a design engineer; working carefully and understanding quickly is what is required. I have experience designing a trial venturi scrubber tool that functions to reduce pollutants caused by thick smoke waste. I read a lot of references so I could create the tool. This is for the progress of the company.

Regularly Review and Validate designs -Peer reviews : Conduct regular design reviews with peers and other departments (manufacturing, quality control, ) -Prototyping: Creating physical/ virtual prototypes for validation -Testing : Untested efficiency can add no value , usage of simulation softwares for real time analysis to verify that design meets functional and performance requirements. ———————————————————-

Understand the capabilities of 3d software under use, also have filers & check points as per specific products or assembly needs some software have special features or can be customize as per need.

Thorough reviews of your CAD models can help catch problems early. Pay close attention to dimensions, tolerances, and how components fit together. Use different views and cross-sections to inspect internal structures and compare your model against original design specs. Catching errors early saves time and money compared to fixing them post-production.

In many mechanical design CAD software applications, the ability to select and move a part helps identify any missing constraints and potential interferences. I consistently test the mobility of my designs to ensure that all constraints are properly applied and that the intended range of movement is achieved.

Measure twice, cut once... Reviewing your models may cost time but saves many problems down the manufacturing process. A simple check of critical dimensions plus a more thorough analysis of moving parts is a good way to review your work. Simulate different positions of your moving assembly and look for interferences.

Regular and thorough reviews of your CAD models are essential for detecting issues. Implement a systematic approach to inspect all aspects of your design, paying close attention to dimensions, tolerances, and the integration of different components. Use the CAD software's capabilities to create different views and cross-sections to examine internal structures and ensure that all parts fit together as intended. It's also beneficial to compare your model with the original design specifications to verify accuracy. Remember, catching errors during the review phase is much more cost-effective than after production.

On first review will identify some mistakes and keep in mind with out correcting those, then will ask other to review again, if the 2nd party will find some other mistakes together with the hidden one, so we can confirm almost covered the checking process

"A broomstick is more useful than a single stick" By sharing thoughts with other colleagues, problems that were previously difficult to solve will become trivial problems that can be solved so easily.

Collaborating with colleagues can provide new perspectives on potential design issues. Utilize the sharing and commenting features of your CAD software to facilitate communication among team members. This collaborative environment enables collective problem-solving, where insights from various disciplines can highlight issues that might not be noticed individually. Ensure that feedback is clear and actionable, and consider regular design reviews with your team to foster a culture of continuous improvement.

Different eyes can help you spot a problem. And better yet, help with a different solution that you may have not thought about before. We all have biases, a way around them is second opinions and collaboration.

Collaboration opens doors to new insights and provides innovative solutions to design challenges. Leveraging CAD's collaboration features among multidisciplinary teams can produce unique and innovative solutions that otherwise would not have been reached. Through this collaborative environment, diverse perspectives from different disciplines converge, shedding light on potential issues that might effect different teams. Clear and actionable feedback enhances problem-solving, driving the refinement of designs. Regular design reviews with the team cultivate a culture of continuous improvement, ensuring that each iteration reflects collective expertise and contributes to the evolution of superior designs.

Finite Element Analysis (FEA): Use FEA to simulate the design under various conditions to identify stress points, deformation, and potential failure areas. Thermal Analysis: For designs involving heat transfer, conduct thermal simulations to identify hot spots and cooling requirements. Kinematic Analysis: For moving parts, perform kinematic simulations to ensure proper movement and avoid collisions. Computational fluid dynamics: is a branch of fluid mechanics that uses numerical analysis and data structures to analyze and solve problems that involve fluid flows. Based on my experience, Siemens Simcenter products are the best tools for FEA simulations. For CFD projects, Simcenter STAR-CCM+ stands out as the premier tool.

One time at work, during our FSAE competition preparations, we used thermal simulations to improve heat dissipation in the engine bay. By simulating various scenarios, we identified hotspots and optimized the cooling system layout. This approach allowed us to ensure better performance and avoid overheating issues without having a breakdown during the competition.

If parts move, I definitely recommend utilizing a collision tool within your CAD software of choice. SolidWorks has a collision detection tool, which allows you to see which parts collide when moved. It can be as simple as dragging specific parts and watching if any other components are highlighted, which indicates a collision. I have definitely avoided unpleasant surprises during the build phase using this tool.

Realistic simulation in CAD software is a game-changer. Tools like stress tests, thermal simulations, and fluid dynamics provide a virtual testing ground that helps predict performance under actual conditions. By identifying potential failures or inefficiencies early on, we can make necessary adjustments before creating any physical prototypes. Remember, the effectiveness of simulation is directly tied to its accuracy—precise simulations lead to better design outcomes.

Of course it's impossible to consider every single variable that can change in the real world and simulate it but it's usually best practice to try to get close to real-world simulations by considering major variables (loads that are most likely to affect your design) and setting minor variables as constants.

Most CAD softwares have an optimization tool that automatically optimizes your design by considering the loads you have placed on it and the factor of safety. This is extremely useful in saving material, removing unnecessary support structures and so on but the output is usually crude. You will have to finalize.

Bajo el concepto de mejora continua, el dise?o iterativo nos permite identificar y optimizar los modelos 3D que suelen presentar oportunidades de mejora, me ha servido preparar los dise?os por etapas de desarrollo para refinarlos y llevarlos a su mejor condición.

In my experience, iteration is key to creating high-quality designs. During my Formula Student projects, such as designing and manufacturing Go-Karts and ATVCs, we went through multiple design iterations. Each time, we tested, received feedback, and made necessary adjustments. This iterative process helped us refine our designs, ultimately leading to several awards and recognitions.

One thing I’ve found helpful is keeping detailed documentation of every design change and the reasons behind them. During my Formula Student days, we maintained thorough records of our modifications and the problems we encountered across all our projects. This documentation was invaluable not only for keeping track of our progress but also for transferring knowledge to future team members. It provided clear guidance on what to do and what to avoid, helping juniors and future generations build on our experience and avoid repeating the same mistakes.

Dans un but de pérennisation des projets, un point me semble important en plus des rapports de suivie, c'est d'avoir des méthodes de dessin commune à l'ensemble de l'équipe de projeteur afin de facilité les transfert au sein du service.

Me ha resultado útil mantener un registro histórico de los cambios que se presentan en el dise?o ya que en ocasiones los cambios que se realizan no resultan factibles para llegar al objetivo y es necesario dar un paso atrás para evaluar nuevas oportunidades.

Dont assume your inputs are 100% correct. Ask questions when something doesn't add up. I was once told: "You are not getting payed to assume, give me an educated guess at least". Backup your decisions on evidence.

Pay attention to the information you’re being given from architects, engineers, and/or senior designers. If there is an inconsistency for example, incorrectly labeled wire terminations, ask about it, it could have been an oversight, or the information may not have been available.

No one has a monopoly of knowledge as such in performing any major development in a company or establishment, always give chance for criticisms which will lead you into taking better decisions or attaining better goals. As a CAD expert, it's absolutely wise to present your designs to team members or reliable colleagues and your boss so earnest criticisms could be given into the idea developed.

If you are working on full system. Try to build the related component out of current design scope but have direct dependency on the product. This help you to under the interaction your product is having and will help you to identify challenges before hand than last minute patch work. And second never shy away from rebuilding the whole model parametrically. This may look tiresome today but will give peace of mind for ever.

Al momento de dise?ar considero que siempre es importante imaginarse el entorno en el cual se está trabajando y como quedaría una vez construido. Usualmente esta ausencia de realidad, que ocurre cuando solo se trabaja desde oficina, genera un desacople entre los dise?os y la vida real. Considero importante que un mejor dise?ador es aquel que no solo puede ver sus propuestas sino que aprende de sus errores para mejorar en sus proyectos futuros.
