Product designers help make products which aren’t just easy and delightful (or at least satisfying) to use, but also fine-tuned to do consistently well in the marketplace. They help define product goals, create product roadmaps and, ideally, help brands release successful products.
Designing a new product goes through an analytical process and relies on a problem-solving approach to improve the quality of life of the end user and his or her interaction with the environment. It is about problem-solving, about visualizing the needs of the user and bringing a solution.
The design process is divided into many different phases, which include various form of sketching and prototyping. However, sometimes the idea starts from a problem people may experience, and designing a solution to solve it.
Do you have an idea & make it in to a product to market? Having trouble with your existing product & want to solve? Or any other support you need on your product development and you looking for someone to help you with, below are the areas I will be able to help you with,
Maintaining strict quality control and keeping production running at maximum efficiency has become too complex for people to manage directly. Modern high-speed manufacturing requires extensive networks of instrumentation, controls, and automation systems throughout production, storage, and shipping operations. Today’s highly increasing competitiveness over the industry demands high quality and most consistent products with a competitive price. To address this challenge number of industries considering various new product designs and integrated manufacturing techniques in parallel with the use of automated devices.
Automation of factory or manufacturing or process plant improves production rate through a better control of production. It helps to produce mass production by drastically reducing assembly time per product with a greater production quality. Integration of various processes in industry with automated machineries, minimizes cycle times and effort and hence the need of human labour gets reduced.
From robotic handling systems to vision quality inspection systems, fully & semi automated packaging, pick & Place robots, and automated storage and retrieval systems, I have helped clients implement cutting-edge technology to meet their production, quality, and efficiency goals.
I can help you automate/semi-automate any of your production lines with supports below,
The successful running of any mass production depends upon the interchangeability to facilitate easy assembly and reduction of unit cost. Mass production methods demand a fast and easy method of positioning work for accurate operations on it. Jigs and fixtures are specially designed so that large numbers of components can be machined or assembled identically, and to ensure interchangeability of components.
More and more jigs & fixtures are employed in electronics manufacturing for assembly, dis assembly, calibration & various electrical testing of components to make defect free products to market to have edge in the market and to suit the raising demand of the market.
From screw fixing, leak testing, pressing jigs, calibration fixtures to inspection gauges & fixtures, I have helped clients in developing large numbers of fixtures which helped clients to improve their productivity by reducing human errors and achieving great consistency in quality.

Most products are made up of one or more components. Each component will need to be manufactured and the process used will depend on the components' application and specification. Choosing the optimal material and manufacturing process combination for a given engineering component application is mostly non-trivial and involves considerable design expertise and experience. This choice is not made in isolation of a lot of other conflicting design issues, technical and non-technical, as well as the need to satisfy interface requirements with adjoining components.
I can work with assemblies of various complexity ranging from a couple of parts to several thousand. I can design your complete product, addressing each component individually and ensuring that all components fit and function together.
I have vast experience of designing components for the most common low to high volume manufacturing processes including

Reverse engineering, sometimes called back engineering, is a process in which software, machines, aircraft, architectural structures and other products are deconstructed to extract design information from them. Often, reverse engineering involves deconstructing individual components of larger products. The reverse engineering process enables you to determine how a part was designed so that you can recreate it.
In some cases, the only way to obtain the design of an original product is through reverse engineering. With some older products that have not been manufactured for 20 years or more, the original 2D drawings are no longer available. Often, there will be no way to contact the original manufacturer, as the company may no longer be in business. In a highly competitive global market, manufacturers constantly strive to shorten lead-times to bring a new product to market. With reverse engineering, a 3D model can be quickly captured in digital form and remodelled if necessary or exported for a variety of manufacturing methods.
CAD is used to create two- or three-dimensional (2D or 3D) graphical representations of physical objects. In product and industrial design, CAD is used mainly for the creation of detailed 3D solid or surface models, or 2D vector-based drawings of physical components. Reverse engineering requires a series of steps to gather precise information on a product’s dimensions. Once collected, you can store the data in digital archives. Often, engineers will enhance the design with new developments and innovations. Sometimes, it is possible to replicate the original model exactly and I have been able to help in below areas,
While the power of a hardware product comes from its internal components, a product is typically recognized by its enclosure, the outer shell that encloses electronic products, making them appealing and user-friendly. Most electronic products, appliances or machines have some sort of a housing or enclosure that protects and holds all the internal components together.
In today’s competitive market, for a product to be successful, it is important to have a custom designed, sleek and user-friendly product enclosure that also does the job of enticing and delighting the consumer. The technology inside your product may be the most advanced, but if it fails to visually entice the buyers, you may be hindering the chances of your success.
I design custom product enclosures that are aesthetically pleasing while being reliable and easy to manufacture. We work on a variety of products like consumer electronics, machine enclosures, instruments, handheld products, wearables, IOT and more.
I have hands on experience on developing Plastic enclosure, Handheld enclosure, Aluminium enclosure, Diecast aluminium box, Stainless steel box, IP67 waterproof enclosure, Junction box, 19"rack mount enclosure, PCB enclosures for electronics devices, Variety of enclosures as handheld enclosures, wall mount enclosures or desktop enclosures, ergonomically sized for handheld use and Dustproof plastic enclosures in IP67, IP65, and IP54 protection standards. I can help you with,
Finite element analysis (FEA) is the process of simulating the behavior of a part or assembly under given conditions so that it can be assessed using the finite element method (FEM). FEA is used by engineers to help simulate physical phenomena and thereby reduce the need for physical prototypes, while allowing for the optimization of components as part of the design process of a project. FEA enables you to predict potential design issues and therefore minimize risk to your product, profits, and your business.
FEA uses mathematical models to understand and quantify the effects of real-world conditions on a part or assembly. These simulations, which are conducted via specialized software, allow engineers to locate potential problems in a design, including areas of tension and weak spots. FEA can be used to optimize the performance of a new product, verify an existing product, or modify a product for a new condition.
FEA can also be used to:
By integrating virtual testing early in product development, users can develop more accurate and reliable product designs while reducing the need for costly prototyping.
Geometric Dimensioning and Tolerancing (GD&T) is a design approach and manufacturing mechanism that helps engineers and designers communicate how to bring a part design to life. When documented correctly using GD&T, it is possible to build a part that exactly matches its on-paper plans.
GD&T uses a symbolic language to indicate how significantly part features can deviate from the geometries listed in the design model. This language contains all relevant details involved in fabrication, including dimensions, tolerances, definitions, rules, and symbols that communicate a component’s functional requirements. These all currently follow ASME Y14.5M-2009 (previously ASME Y14.5M-1994).
While many applications benefit from GD&T, there are certain situations in which the process provides fundamental assistance, including scenarios in which critical or interchangeable parts fit into a larger assembly, tolerance analysis needs simplification, thus it becomes clear to have an in-depth hands-on exposure to when, where and how to use GD&T.
Tolerance stacking involves finding the cumulation of all individual tolerances of a component or assembly in order to understand the potential range of final fits. Proper tolerance stack up analysis also enables you to predict how your final component will look, function, and interact with other components — this is particularly important when it comes to manufacturing mating parts.
Accounting for tolerance stack-up helps ensure tolerances can be manufactured before manufacturing even begins. This prevents you from having to go back to the design process after moving to the prototyping or production stages, which can save time, money, and resources. Calculating tolerance stack-up can also save you money by helping you understand your tolerances in context, so you can optimize for cost and manufacturability.
Efficiently and accurately accounting for tolerance stacking is far easier with the help of a trusted engineer and I am here to help ensure your tolerances are correct before manufacturing. I will also guide you throughout the entire manufacturing process, working with you each step of the way to ensure the best possible results.
Additive manufacturing, aka 3D printing, is the process of producing 3-dimensional objects from a computer file, where the part is built by adding material layer-by-layer. Today, more companies in a variety of industries are embracing the 3D printing process as it presents many significant advantages over the more traditional manufacturing methods of subtractive manufacturing and injection molding.
One of the biggest advantages of 3D printing technology is Rapid Prototyping. Rapid prototyping is the ability to design, manufacture, and test a customized part in as little time as possible. With 3D printing techniques, a business can design a part, manufacture it in-house on a professional 3D printer, and test it, all within a few days (and sometimes even less). For small production runs and applications, 3D printing is the most cost-effective manufacturing process.
Different 3D printing processes have different capabilities and different design restrictions like choosing correct wall thickness, overhangs, deciding on round corners to avoid warping etc. Each vary in the way they form plastic and metal parts and can differ in material selection, surface finish, durability, and manufacturing speed and cost. So, it is important for designers to have thorough knowledge on each of the process in order to design products for specific method of 3D printing technology.
I have a great understanding on both Polymer 3D Printing Processes (SLA, SLS, PolyJet, DLP, MJF, FDM) & Metal 3D Printing Processes (DMLS & EBM) and I have been helping companies on design and 3D printing activities such as below,
Learning, as they say, is a never-ending process and is very crucial for people to keep growing. And when you are an employee, learning becomes your force to move ahead. Learning has been a concept that has evolved with time, which does not end with a degree or after you settle down with a good job. It is a lifelong process. You always find something new to learn every day.
And somehow, between all the chaotic developments, we have adopted different ways and means to learn new things. To keep up with the advancements of today's world, you need to keep yourself updated with new skills and knowledge. According to a survey, 54% of employees have said that it is essential for them to get training and develop new skills throughout their work-life to keep up with the changes in the workplace. With today’s rapidly changing pace of the occupation market, employees need to stay informed concerning new technology and knowledge. It is heartening to note that many organization value industrial training as an approach to prepare future employees and consider offering such training programs as their corporate social responsibility.
Continuous learning is most effective when the individual has a desire to learn and grow regardless of their present knowledge & current position in their career. This is especially useful for constantly changing industries, which require professionals to stay constantly updated with industry trends and learn modern skills.
Knowledge is now at everyone’s fingertips. Those not making use of this opportunity will remain where they are – their capabilities diminishing in importance. Always have a curious mind. Explore different topics and don’t be afraid to ask for clarity. Be inquisitive, and if your intent is sincere, there will be people who will help and support you in your journey.
An engineer who gets the industry-oriented training will be able to hone skills and gain knowledge in his or her technology field.
