The consumer market is growing rapidly too: here, PwC predicts a jump from $72 billion in 2015 to $236 billion in 2020. Between them, businesses, governments, and consumers will invest nearly $1.6 trillion to install IoT solutions in 2020.

Gartner has estimated that the Internet of Things will grow to 26 billion connected devices by 2020. This compares with the 0.9 billion connected in 2009 and represents a thirty-fold increase over the last ten years.

Moreover, this is just the beginning. Analysts at Juniper Research say we are only now entering the incipient scaling phase of the Internet of Things. They predict the number of connected devices will reach 50 billion by 2022.

The growing market for IoT devices

Then, it is no surprise that there has been a shift towards developing intelligent devices in many an organization’s new product development strategies. Established businesses and start-up entrepreneurs want to get a slice of this growing market. Furthermore, it is a fast-growing market: PwC says business investment in IoT solutions will grow from $215 billion in 2015 to $832 billion in 2020.

The consumer market is growing rapidly too: here, PwC predicts a jump from $72 billion in 2015 to $236 billion in 2020. Between them, businesses, governments, and consumers will invest nearly $1.6 trillion to install IoT solutions in 2020. However, PwC says the most investment will be spent on software and application development again. Furthermore, this points to one significant difference when designing a new product for the Internet of Things: you need to consider associated software as an integral part of the functionality of the end device. Since most of this software will be hosted in the cloud, this new consideration comes second to the other key component of any Internet of Things product: the connectivity itself.

Where are the opportunities for Internet of Things product design?

This illustration shows the key sectors where IoT device growth is expected to be most vital.

Whatever sector you are in, the design of your IoT device must incorporate the two new elements fundamental to the IoT:

1) How are you connecting your device? 2) Why are you connecting your device?

At the very early stages, you need a clear idea about the answers to these questions because this will impact the decisions you make about the connectivity and any associated software, and the design of the device itself.

Why are you connecting your device?

The starting point has to be the user. We have written in the past about the importance of user-centric design (read the blog here).

Why will the IoT widget you are developing be so much better than the standard widget that does not connect to the Internet that consumers can buy now? Are you pulling data from the Internet to give the customer more information or aid the operation of the device? Or are you sending information back to the Internet in order to add value for the consumer via an App – perhaps using stats recorded locally by the device or about the operation of the device itself?

It is vital to put yourself in the consumer's mind to understand the value add is delivered and how this could best be achieved. Essentially, does your design have legs? Consumer research, ideation, concept evaluation, and other feedback mechanisms will help you decide whether to progress from the drawing board into prototype production.

We can help you with these early stages of product development and the design stages. Find out more here.

Why Connectivity Matters.

When designing an IoT product, the second major new consideration is: how are you connecting your device? There are many ways to connect your device to the Internet of Things. Perhaps your product is designed to aid quarry or mining operators to manage their tooling and kit at the site. In this case, it may be more applicable to use radio frequency across a remote wide-area site that is poorly served by mobile phone networks, then use a hub controller to feed data to the Internet via a standard telephone connection.

It may be that your product is designed to be used in a “smart home” where good Wi-Fi coverage makes connectivity over the home Wi-Fi a no-brainer. Alternatively, perhaps the product is designed to be out on the road all day monitoring and tracking the movement of goods or vehicles. Perhaps a combination of GPRS and a mobile phone SIM card will be the most appropriate method of communication here.

Thinking about how your product will be used – and where – will help you make decisions about the sort of connectivity your device will require. This is important to consider at an early design stage because these connectivity elements will be fundamental to the design.

For example, suppose you send data between your device and a hub controller via radiofrequency. In that case, you will need to incorporate a transmitter and a receiving antenna into the design of your IoT device.

Suppose you are going to be using GPRS and 4G phone signals. In that case, you will need to incorporate a SIM card holder that is appropriately accessible, plus charging ports (since this method of communication is likely to be heavier on the device battery) and the appropriate transmission and receiving technology.

The importance of good design in any new IoT product development.

We have considered the two major differences when designing a product that will leverage the exciting new possibilities offered by the Internet of Things. Now let us consider one aspect that remains the same: the importance of good design.

Design is critical to any new product development. It will affect the three most important factors that will influence whether or not your product is a success:

1) The functionality 2) The usability 3) The look and feel

Once you have a clear idea of why you are connecting your IoT product and how you will connect your IoT product, your design process will follow much the same process as any other product – albeit referencing these two major factors throughout.

You will need to list the essential functional elements, agree on a look and feel and what branding elements you wish to incorporate, build a 3D model or prototype using a design methodology called rapid prototyping, seek feedback from your potential customer base, and adapt the design accordingly. Here at Criador Labs, we have a wealth of experience guiding both new and established businesses through this journey.
