POC to Product: 8 Key Processes in Design Path

POC to Product: 8 Key Processes in Design Path

A recent Hardware Massive Taipei event featured David Peng as the evening’s speaker. Peng has more than 25 years of experience in the electrical industry, and has a large amount of knowledge in product design, marketing, promotions and project management. He is co-founder of SlingX Corp, through which he shares his advice with startups and entrepreneurs. Peng discussed his eight key processes in designing a product from the point of view of design and project management.

Key Takeaways

1) The 8 Aspect Thinking in Designing Product

There are eight things to think about when designing your product — a system block diagram, your usage environment, certification, manufacturing tests, mechanical design, layout strategy, status transitions and APP and the cloud.

2) System Block Diagram

A block diagram is a diagram of a system in which the principal parts or functions are represented by blocks connected by lines that show the relationships of the blocks. Use this series to think about your product. Think about your function, interface, voltage, power budget and cost. Discuss these concerns with your designers.

3) Usage Environment 

Product marketing has to list the possible user scenarios, especially for some extreme conditions, and the designer should take these scenarios into consideration. These scenarios should make designers take some reliability tests, to ensure certain environments will not inhibit use. For example, your product should be able to meet temperature and humidity tests. It should also be able to resist vibration levels of a normal concern, as well as normal drops. A HALT test (Highly Accelerated Life Testing) can help you discover the weak links within your product.

4) Certification

Check with the Federal Communications Commission, or whichever authority holds power in your country, to see which certifications your hardware product will need. These certifications will also help you to meet certain guidelines that help make your product better, and keep it from suffering from electrical shock damage, energy damage, fire damage, radiation damage and others. 

5) Manufacturing Test Requirement

These requirements will guarantee your product quality and lessen your manufacturing costs. You’ll want to have a manufacturing test plan, test points and a test tooling design and a manufacturing test program.

6) Considerations in Mechanical Design

When considering your mechanical design, think about a few of these — 3D interface checking (which checks with any interference between housing, electrical components and mechanical components), thermal consideration (discovers the thermal impact on a system once it does not have a good heat dissipation system), antenna placement criteria and waterproofing. 

7) Layout Strategy

Think of a few facets when considering your layout strategy. First, Power and Ground is the most important item that a designer must consider when engaged in PCB layout. Safety requirements must be met between the power, signal and ground. Additionally, it’s important to have a layout path as short as possible. 

8) Status Transition Diagram

This tell you how the system works and how your product is behaving. Use this diagram to talk with your teams to keep the flow of your design working forward and moving ahead, without mistakes made or walking backwards. 

9) APP & Cloud

Lastly, start thinking about user interface and user experience as far as your design is considered. Where should things go and what colors should be used? How creative should your visual pieces be? What type of mobile app development do you need? Apps and the Cloud are the last parts of your project that you’ll want to consider.
