How To Make A Guide on Design for Assembly For Products

Design for manufacturing and design for assembly are two different methods. DFM deals with selecting materials during the manufacturing process. As for DFA, it optimizes workpieces during the assembly process. A proper design is vital for manufacturability. Such a procedure involves the creation of products that are easily assembled. At Creatingway, we deal with workpieces joining them effortlessly with accuracy. All of these positive attributes are to boost your projects’ quality and lifespan. By doing so, you will save on repair costs and benefit economically. Below is a complete overview of the design for assembly.

How To Define Design for Assembly?

The act of designing and assembling workpieces easily is called DFA. Our objective is to reduce the number of parts and the time taken to assemble them. Such a process is very important to engineers as they design products. Engineers use DFA to optimize a product design during assembly. Also, they ensure the quick assembly of the products with minimal costs spent. The process occurs during the development cycle before the making of any prototypes. This step allows engineers to make necessary changes in the design of the workpiece. The modifications allow an easier assembly process with precision.

Principles of Design for Assembly

DFA offers guidelines and a set of rules that help in designing a product. The main aim is to ensure an easy assemble process of a workpiece. It is vital to adhere to the critical principles of DFA. As it helps in reducing money and time spent during the assembly. Also, the quality of the product increases, boosting the customers’ satisfaction. Below are the principles of design for assembly

Considering Modular Designs

We achieve efficient and fast assembly by incorporating modular assemblies.?Moreover, modular designs standardize items that are interchangeable in terms of shape and size.

Modular designs have various benefits. One it being making systems more scalable. The systems are easily modified or expanded without redesigning the entire system. Also, systems become more flexible, making them adaptable to the environment.

Reducing the Number of Parts

One of the major aims of DFA is to reduce the number of parts. A workpiece count is crucial in the design quality of a product. We tend to have fewer parts to achieve good products. So, with such minimization, it’s easier to repair and maintain the parts. Also, it’s easier to manufacture more durable workpieces in a small number.

Build-in Fasteners

We incorporate fasteners to reduce the number of parts assembled. In doing so, bolts, screws, and other additional items are eliminated. The eradication increases the speed required in the manufacture of products. An alternative method is joining parts without the use of fasteners. We use nails and screws in place of the pins. Also, snap-fit parts fit in perfectly without the aid of bolts. The snap-fit is easier to disassemble and assemble and won’t get loose over time.

Improve Assembly Operations and Process

As we reduce the number of assembly operations, the production process increases. One considers the type of assembly process while designing a product. These main types include manual and automated. The manual assembly process is slower and less efficient than the automated ones. Though starting and maintaining a computerized method is expensive, it’s better to deal with.

Creation of Symmetry Design

To create a more pleasing design, we use symmetry design. Most products are designed with symmetry to fit parts correctly and quickly. While using DFA, the principles are strictly followed. The balance consists of two main types; rotational and bilateral.

Rotational symmetry allows the movement of a product in the central point. Such a process requires the assembly of multiple parts to position them easily. However, with a bilateral system, products are divided into two separate halves. Each half is similar to the other with no or minimal differences.

Use Mistake-Proofing

This principle is also vital in the developmental product process. We tackle challenges more quickly, making parts fit more accurately. Mistake-proofing enables manufacturers to assemble parts without any errors. Also, the process is much faster and more affordable, avoiding the risk of blunders.

What Are The Advantages of Design for Assembly?

Increases products’ reliability

Designers look for reliability in products by minimizing the number of assembly workpieces. Disassembling and assembling them isn’t that difficult either. In doing so, the likelihood of failure decreases.

Eases setting up automated assembly

Steps of simplifying assembling machines or robots become easier. The items align themselves fluently, increasing the efficiency of the production process.

Decreases the cost of production

It is easier to design better products at a cheaper cost via DFA. Since we only require a few products in the assembly process.

Decreases material wastage and usage

What’s The Difference Between DFA and DFM?

The two terms are often confusing, although they are different. We use DFM to make products cost-effective. As for DFA, it aids in designing products making their assembly easier.

DFM majors in reducing production costs by minimizing costs. Also, the efficiency and lifespan are maximized. DFA focuses on the quicker assembling of products with zero errors. Labor costs are also reduced since it’s easier to join workpieces without wasting time.

To fit in parts accurately within minimum time, we use DFM. As for DFA, the process is easy, and un-trained professionals can use the method. There are minimal factors leading to damage or confusion when using DFA.

?A reduction in material wastage helps in cutting unnecessary costs. Therefore, DFA processing is advantageous to both consumers and manufacturers.
