Specifying a new design
AirBorn Electronics provides custom manufactured electronic circuitry. The information provided here is intended to help you specify your new design. Probably the best way to use this information is to print this document, then write in the margin of your printed copy.
Give your project a name
Your project name could be:
- Descriptive: Sonar1 - Underwater buddy-line sonar
- Just a tag: Chicago
- An acronym: RIO - Remote Input/Output unit
- Or it could be catchy: The Silent Salesman
You'll probably be using this name a lot in the future - If you keep your project name short, it'll save you time! If it's 7 letters long, and unique enough to do a text-search on, you've got a real winner.
Describe your project (Opening Statement)
- Keep the first description short.
- The first sentence should summarize the whole function of the project.
- Describe or name equipment, devices or interfaces that the project uses or connects to
- You should fill in the detail of the project's specification later.
Examples
- Input Expander Unit. The input expander attaches to the RS485 bus from the rainmaster control system and provides a method for connecting additional 4-20ma analog and switch contacts to the rainmaster.
- Fragrance dispenser. The Fragrance dispenser provides timed bursts of air freshener (as set by the timer and mode controls) while room lighting is on or a room occupancy sensor is active.
- Al Roller controller. The Aluminium roller controller takes its input from a Mitutoyo LSM602 & LSM3000 laser micrometer, and, with values entered by keyboard and LCD display, controls the thickness of the aluminium sheet produced by the rolling machine. The controller provides relay outputs to drive the UP & DOWN contactors, together with a separate FAULT circuit to indicate out-of-tolerance product.
We are actually doing things a little backwards here, but the natural way to list things is to Name your project, then Describe your project. In fact, at the risk of sounding patronizing, successful projects are invariably originally conceived by first recognizing the market need that the project will satisfy, then finding the particular market the project will service, then describing the project, then giving it a name.
Describe your projects market
- Your project may sell to a particular group of people: Air conditioning installation companies
- Your project may sell to an established client base: Accessory for the existing rainmaster system
- Your project may satisfy your own requirements: Custom Plant for existing factory, no likely external sales
- Your project probably has a particular market position: Low cost, sold through Locksmiths
Describe the market need your product fulfils
Examples
- Provides the only method of expanding the rainmaster system. About 33% of rainmaster system users would probably also purchase additional inputs capability.
- Provides a more cost effective method of neutralizing odours - an existing market.
- Al Roller controller. Existing manual method is leading to substantial material wastage and tolerancing problems. Automatic control is a requirement for ISO9000 approval.
Again, we risk sounding patronizing... we are not writing an economics text book here, but if you can't identify a market need for white elephants, then it's best to think twice before committing your resources to producing them.
Describe your sales model
The traditional way
Make something, then sell it - this is the method we concentrate on below.
Outsource production - this doesn't need a seperate category, these days you really have
to outsource manufacture at some point. It is not hard to manage, the best way is to start with
as much outsourced manufacturing as can easily be arranged. If you find the prices that you are
paying are too high, find an alternative manufacturer - or manufacture yourself. Most successful
business relationships revolve around letting your suppliers make money - but making sure your
own company does the same, and preferably on a similar timescale. The advantage of using AirBorn
Electronics for your design work is that you will get top quality, well documented designs, and
you will own the design. That allows you to pick another company to outsource to with only
a few weeks downtime. If you have the outsourcing manufacturer do the design work - and believe
me they will push very hard for that - then you will never own your product. They will.
Sell the Refills
You can also make something then 'sell the refills' - this is the sales model used for most
low cost PC printers - and could, for instance, be used by our air freshener example.
Being conservative, it makes sense to try and cover your manufacturing and overhead costs on the
unit sale, with perhaps a small profit. If you make most of your money on the refills, you have
a continuous income stream, the most desirable situation.
Licensing
Licensing - a tricky one most easily handled by a large organisation. It is harder to sell,
harder to police, but lucrative with little downside risk. Be wary of developing a product where
your potential customers are much larger in business size than yourself, unless you have
substantial entrepreneurial flair, excellent sales and negotiation techniques, and a piranha of
a lawyer where you have sufficient funding to match. In years gone by, the classic example was
to try and sell something to a car manufacturer - you just could not expect to profit from it.
You had to sell 'aftermarket' and try to move quickly, but if the gadget was really effective
sooner or later you could expect it to become the 'new feature' on next years model of car, -
without you getting paid for it
I would suggest that exactly the same situation now applies to Toys and mobile phones - you just
cannot hope to sell to the market encumbents without deep pockets for expensive legal services.
You will notice I have not used the word patent at all until now - I think a patent without a
lawyer is like a gun without bullets. Ofcourse you need the patent, but unless $2000 an hour does
not scare you (the going rate for a top patent protection lawyer in Sydney), you might consider
easier ways to your living. Try to find the exceptions - for instance it might be next to
impossible to profit from your idea to, say, make a barcode scanner for a mobile phone - but it
may be quite straightforward to produce an aftermaket iphone app that could do that function.
Subscription model
This is the usual breadwinner - become a service company. Normally the product is a delivery
mechanism for the service - and the subscription allows continued access to the service. Again,
mobile phones are an excellent example - I mean you don't honestly think those phone calls cost
the telecom companies anything to provide, do you? Their costs plateaued soon after the mast
went up in the air. There are many, many opportunities in this field. You do need to carefully
analyse the psychology of your market to set the pricing. More especially with a younger market
it can pay to keep the upfront costs low, and make the offer enticing. Overall, the secret is
to make the costs affordable, then find some way, any way, to get the people to
sign up. Surprisingly, once they are signed up, there is often reticence to un-sign, if the
cost is 'low enough not to worry about'. The cost just keeps being debited to the account.
The writer has issue with the practices of some companies using the subscription model, however
those practices are very relevant to profits, so I feel an obligation to share those of which I am
aware. The point is, the subsciption model can be very lucrative in unforseen ways. One method
is 'Bait and Switch' - the supplier offers an excellent deal, then at some point in time makes
the enticing offer unavailable, replacing it with an offer more profitable to the supplier.
Surprisingly, many stay, dependent on when and how the switch is made.
A standard technique is the pricing of extras. It works both ways - for instance a telecom
company might headline their offer with "Call for as long as you like - pay only for 1 hour" -
but in reality the average call is 3 minutes long, so the impact on their profit is low.
Conversely, many ISPs offer internet access, up to X Gigabytes, for a monthly subscription of,
say $30. However, beyond that, 2X gigabytes may cost $112, and 10X $850. In reality most useage
will be far below the X gigabytes, but when with some clients it does go higher, it often goes a
lot higher (perhaps most normally through malware or naive downloading). In both cases the
supplier has more knowledge of customer behaviour than the average customer themselves, and has
carefully crafted their pricing to be less transparent, but more enticing.
The key driver of customer satisfaction in service industries is customer support - if you
resolve problems quickly and efficiently you gain customer loyalty, even despite your pricing.
Okay, back to the electronics -
Estimate the production volume
- Estimate a budgetary sales price
- Estimate the market volume in units per year (see our section on economies of scale)
- Estimate the likely market share at the budgetary sales price
- Estimate the lifetime of the market
- Estimated production volume = (market volume ) multiplied by (market share) for (lifetime)
years ...be aware this normally ramps up then slowly down
Some clients believe that identifying their market, the market need and the market volume to a design subcontractor is tantamount to giving away a market opportunity. A design subcontractor is likely to produce poor results if this important information is kept hidden. Experience shows many products fail to gain market share because the client never really got the designers in tune with the market. Also from experience, the only situations in which I have seen design and manufacturing subcontractors "steal" a clients product idea (atleast in Australia) is when the client fails to pay for the work!
If the client is still unwilling to disclose market information, perhaps the best course of action is for the client to file for a provisional patent to protect the intellectual property, and then engage the subcontract design house.
The types of specification points or clauses
The best way to arrange a specification is as a list of bullet points, or clauses. Bullet points
have the advantage of being clear and concise. A specification should describe all the
required attributes of the project - make a separate, if attached, wish list.
When writing a specification it is important to distinguish between required and desired.
Think carefully before you state a desire as a requirement - if you specify that the project
is to be no larger than a mobile phone, be sure that the market really warrants that feature,
because it may cost you a substantial amount to achieve.
A specification reads like a list of project features, describing the unit, and will usually include:
These points are expanded upon in Specifying a new design: Technical ingredients
- Inputs
Describing the project as a "Black Box" it has inputs, a function, and outputs. The inputs are physical electronic connections that are activated by, for instance, an operator pressing a button, or a temperature dropping too low.
- Controls
Controls are often an abstraction of inputs - a potentiometer input may be used to control the speed of a motor, or a keyboard switch may be used to ramp the motor speed down to zero.
- Outputs
Outputs can sometimes be directly related to functions - for instance an UP relay and a DOWN relay
- Indicators
Indicators usually show the status or condition of the device, for instance Alarms, Faults, Modes.
- Functions
Describe functions simply and generally. Describe special cases separately
- Modes of operation
Modes of operation affect functions, for instance Powering up, manual operation, automatic operation
- Power Supply
Choices are usually between Plugpacks, AC power, and battery.
- Protection, Fail safes and replaceable parts
- Connector types
- Physical format and size
Review your specification to ensure it describes the project clearly and succinctly. The specification should describe the project, as you need it produced. The specification can be followed by a wish list - desirable features or possible extensions. Possible extension might include a connector for I/O expansion.
An example of the distinction between the required and the desirable: The size of an electronic project is frequently described as a requirement when it is more often just desirable that it be as small as possible. Economical prototypes and niche market products are rarely as miniature as mass produced consumer electronics.
The specification is a terse point-by-point document with a brief opening description. It often helps to attach a plain written description of the project which is more general, and describes the way the project works more from the perspective of how it is used.
A computer, to print out a fact,
Will divide, multiply, and subtract.
But this output can be
No more than debris,
If the input was short of exact.
