WHAT IS THE ENGINEERING DESIGN APPLICATION

Engineering design and drawing offer a broad subject that includes many theories and practices. It has different forms of drawing at the lunch table as a basic sketch of a new product idea drawn on a napkin.

Additionally, the drawing comes in the form of a complex series of models for a new automotive design. It uses hundreds of formal drawings that require the construction of a skyscraper. One could learn the purpose and requirements and create meaningful engineering drawings by using this textbook to study engineering drawing and design. The engineering design applications offer an early explanation along with systematic problem-solving techniques.

WHAT IS THE ENGINEERING DESIGN APPLICATION

We use specific engineering projects or general design along with drafting concepts. The engineering design application mainly uses post guides through a basic example of an engineering design process. It begins with an idea and a basic sketch that ends with manufacturing an actual product.

From an Idea to a Product

The engineering projects and design ideas establish or occur along with an informal setting. For instance, a hand-tool manufacturing company engineer uses a typically adjustable wrench to complete a common home-repair task.

They used the wrench, where the engineers discovered that it was difficult to access a confined location and remove a nut on a piece of equipment. The engineer additionally imagined how the company could manufacture, design, and market a new wrench. We use features that help in making the tool usable in cramped locations. The other day, the engineer and a colleague used the drafting department. The engineer mainly sketches the idea for the new wrench on a napkin by communicating the design to the drafter.

The sketch mostly shows the idea of taking the existing tool design that creates a whole new handle adding an ogee or S-shaped curve design. Additionally, the sketch communicates the concept that takes a current tool with creating a fresh hold of an S-shaped curve design.

Later the same day, the drafter would offer the three-dimensional (3-D) solid model files using existing wrench design based on the computer-aided design and drafting (CADD) system.

The user mainly uses drafter copies that revise the existing design based on the engineer’s sketch. The drafter represents the engineer’s new model, who is pleased with the results and requests of a rapid prototype. Rapid prototyping (RP) is a process that creates a physical and functional model from a computer-generated 3-D model. It uses an RP machine, known as a 3-D printer. The RP machines are available that build prototypes from various materials like paper and liquid polymer. The hand-tool company do not have an RP machine. Therefore, the drafter sends files of the design to a company specialising in RP. The engineer and drafter receive a prototype two days later.

The figure shows the prototype of the new wrench design. The design team tests the prototype in an application similar to what the engineer experienced at home. The prototype worked as expected.

By the next afternoon, the drafter completes the set of working drawings shown in Figure and sends the drawings to the manufacturing department to manufacture and assemble the new product. The manufacturing department needs lead time to design and make the forging dies required to reproduce the parts. Lead time is the time interval between the initiation and the completion of a production process. Forging is the process of shaping malleable metals by hammering or pressing between dies that duplicate the desired shape. The hand-tool company is small, so the drafter is also responsible for creating catalogue art and copy for marketing the product.

Less than two months after the engineer had the initial idea, the first production run of new wrenches is ready to sell. The figure shows the finished product.

WHAT IS THE ENGINEERING DESIGN APPLICATION

We have the best design team that tests the prototype in an application. It works similar to what the engineer experienced at home. The prototype worked as expected. The drafter supports along with completing the set of working drawings by the next day and sends the drawings to the manufacturing department. It helps to manufacture and assemble the new product. The manufacturing department needs lead time to design and make the forging dies required to reproduce the parts. The Lead time is the time interval between the initiation and the completion of a production process. It helps in the process of shaping malleable metals that presses between dies and duplicate the desired shape. Additionally, the hand-tool company is relatively small. It helps to draft for creating catalogue art and add copy for the product marketing.

Engineering design applications offer numerous benefits that significantly contribute to the efficiency, accuracy, and innovation in the engineering field. Some of the key benefits include:

1. Efficiency and Productivity: Engineering design applications streamline the design process, reducing the time and effort required to create complex models. They enable engineers to work faster and more efficiently, leading to increased productivity and shorter project timelines.
2. Cost Savings: By using design applications, engineers can identify potential issues early in the design phase, minimizing costly errors and rework. This proactive approach helps save money throughout the entire project lifecycle.
3. Improved Design Quality: Engineering design applications allow for more precise and detailed modeling, leading to higher-quality designs. They offer advanced simulation and analysis tools that help engineers optimize their designs and ensure they meet performance requirements and safety standards.
4. Collaboration and Communication: Design applications often facilitate collaboration among multidisciplinary teams, as multiple engineers can work simultaneously on the same project. It improves communication between team members and stakeholders, enhancing project coordination and reducing misunderstandings.
5. Innovation and Creativity: These applications foster creativity and innovation by providing engineers with tools to explore various design options and alternatives quickly. They can experiment with different concepts and assess their feasibility before selecting the best approach.
6. Visualization and Virtual Prototyping: Design applications offer 3D modeling and visualization capabilities, allowing engineers to create realistic virtual prototypes. This enables stakeholders to visualize the final product before physical manufacturing, making it easier to make informed decisions.
7. Sustainability and Environmental Impact: With the ability to simulate and analyze designs, engineers can evaluate the environmental impact of their projects. They can optimize designs to be more sustainable and eco-friendly, aligning with the growing emphasis on environmental responsibility.
8. Rapid Prototyping and Manufacturing: Many design applications integrate with 3D printing and computer-aided manufacturing (CAM) technologies. This integration facilitates the seamless transition from design to physical prototype or production, accelerating the manufacturing process.
9. Regulatory Compliance: Design applications often include features that help engineers adhere to industry regulations and standards. They assist in documenting and validating designs to meet legal and safety requirements.
10. Continuous Improvement: Engineering design applications often receive updates and improvements, incorporating user feedback and advancements in technology. This ensures that engineers have access to the latest tools and features to continuously enhance their design processes.
