Staff Interviewing, as part of AS9100 Quality Manual internal update process. Checking existing departmental and process procedures are still current, to enable updating of Quality Manual revision level. Undertaken as short term contract, and completed 1 week ahead of the allocated time period.

Solution finding & development

  • Development, and integration.

Questions to ask

Who is the product aimed at?

This is also known as the product’s target market.

This is an important first step in the product design process  and will influence the finished product.

As Yesway has ‘in house’ marketing degree expertise, as well as engineering development expertise. We approach and incorporate marketing tools into the product planning process.

Example tools include ‘Slept Analysis’, which stands for Social, Legal, Economic, Political, Technological.

Social: Is your proposed product going to appeal, or acceptable to your target market?

For instance, a new type of bikini aimed at the Iranian market is likely to be a sales failure.

This is because Iran is an Islamic country, where clothing modesty, is the social & cultural norm.

Another example I could give was when I worked for an International Defence Aerospace organisation. The company had previously sold a piece of military communications equipment to a foreign government

The company had previously sold a piece of military space communications equipment to a foreign government. The equipment was a standard

The equipment was a standard design and was shown to another foreign government, who were also interested in purchasing a system.

The ‘Social’ issue in this example was that Country ‘A’, & County ‘B’ were neighbours and rivals.

Country ‘B’ believed that their country & military were superior to Country ‘A’.¬† This was a social factor, which meant that once they heard that Country ‘A’ had bought the same system

This was a social factor, which meant that once they heard that Country ‘A’ had bought the same system, they wanted a better system.

The solution was to re-engineer the same system to have extra ‘indicator bulbs’ on the control monitoring system.

Country ‘B’ was thus satisfied and bought the ‘improved’ system.

Legal: What laws affect your product?

One of the first questions to ask yourself when researching the answer is where are you planning to sell your product.

This matters, as you need to consider not only national laws but international laws also.

For example, if you were developing a LoraWan wireless connected sensor ‘node’, different regions use different radio frequencies.

Therefore you could not develop a product for the North Amercian market, and sell it in Europe, without complying with the relevant frequency laws.

Economic: Can your target customers afford your product?

What might be considered a mass market product in some markets (i.e, western Europe & USA), might be considered a luxury item in the developing world.

The product selling price is an important consideration, as not only will affordability been a consideration, but also desirability.

Studies have shown (such as Mercedes 190 case) that when a product is sold at too low a price, then it can be perceived as being desirable.

In the case of the Mercedes 190, those people looking for a prestige car, assumed the 190 was not as good as other Mercedes, as the price was similar to mainstream alternatives.

A model relaunch, with increased spec & price, resulted in sales taking off.

Political: What changes might affect your product?

Political changes are closely linked to Legal changes.

If you wished to produce novelty domestic incandescent light bulbs, then the ban on them, would affect you.

Research into what is happening politically is an important consideration, for both new and existing products.

Existing products, may be able to be ‘re-engineered’ to adapt them to new political policy changes, such as fitting more efficient engines to the ‘Land Rover Defender’, which enabled it to be produced for so long.

Technological: New technologies & disruptive ideas.

The world is changing faster now, than at any time in human history.

While once upon a time we used Thermionic Valves in our radios, transistors bought about product miniaturisation in the 1960s.

The 1970s saw ‘Silicon Chips’ being introduced, revolutionising computers, making them smaller and more powerful than their predecessors.

Want to buy shares in a VHS video recorder company? Thought not!

Constant analysis of new technologies, and what your competitors are doing with them, is essential.

Latest technology trends include VR (Virtual Reality), and the IOT (Internet of Things).

The above are examples of new disruptive ideas and innovation, which did not exist a few years ago.

Applying the Internet of Things (IOT) to Induction Motor Monitoring

Applying the Internet of Things (IOT) to Induction Motor Monitoring

Induction motors are found in all sorts of industries and applications, both on land and offshore.

Smaller Induction Motors (roughly drawing up to 10 Amps Full Load Current) most commonly use Direct Online Starting (D.O.L) methods.

Larger motors typically use starting methods such as Star-Delta starting, which keeps the starting current (surge / inrush) down.

The Internet of Things offers 24/7 monitoring of systems, which can intelligently react based on the input data provided by the networked sensors.

The main parameters of induction motors that could be measured are:-

Voltage (individual phase)

Current being drawn by motor.

Over current in individual phases, such as imbalances due to single phasing faults.

Phase Winding temperature based on measurement using thermistors.

Vibration Monitoring, indicating bearing failure.

Motor speed (inc comparison of actual to Synchronous field speed calculated speed).

What do we mean by the above parameters:-

Firstly lets consider the term, ‘Voltage (Individual Phase)’.

Voltage (individual phase)

The term ‘individual phase’ is applicable in three-phase supply systems.

Three-phase supplies are commonly used in industrial factories and workshops.

It is rare to have a three-phase supply in a domestic home.

To understand a three-phase supply, lets first consider a single-phase voltage supply.

In single-phase voltage systems (as found in most homes), an ac sine waveform ‘cycles’ above and below the centre zero volts level, at a frequency of 50 times a second.

This is known as 50 Hertz, or Hz, and is the supply frequency used in most, but not all, countries around the world.

single phase as sine wave picture

ac sine wave.

The picture above, shows a representation of an AC (Alternating Current) Sine Wave. The line through the middle would be zero volts, and as you can see the voltage rises and falls over time (time periods, starting at the left of the picture, and moving right).

For an AC voltage supply frequency of 50 Hz, 50 complete sine waves would be completed, per second.

Now that (hopefully) you understand what a sine wave is, you need to know that in a single-phase system, you have one sine wave, that goes up and down over time (as in above picture).

A three-phase voltage supply, has three sine waves at the same time. NOT ONE, BUT THREE!

Each of the three sine waves, is spaced 120 degrees apart, which means in plain English, that they rise and fall, at different times to each other.

For the purposes of Induction Motor Monitoring, you might want to monitor the phase wire, to check whether the voltage is on or off.

If the Induction Motor was a single-phase type, then obviously if the voltage supply was off, the motor would stop.

However, the single-phase motor may be tucked away from view, in a corner of the factory. Therefore being able to monitor the single individual phase supply, is still useful for an IOT induction motor monitoring system.

Being able to monitor all three voltage supply wires, to a three-phase induction motor, is even more useful.

If one of the three voltage supply wires, to the induction motor stopped supplying voltage, the motor would continue to run.

The motor would not run well on only two supply wires, but may go unnoticed, if in an out of the way location.

This is why using an IOT monitoring system, to detect the voltage of each of the three voltage supply wires, is useful.

Current being drawn by motor

Each Induction Motor will have a manufacturers specification for how much current is drawn, both at startup, and when fully running.
