This is quite a vague question, so only a very broad and vague answer can be given. Here are some ways to achieve this: Invest in marketing to increase sales, or hold more stock, so that you can buy parts in larger quantities and get better pricing. Negotiate with suppliers and make a commitment to buy a large quantity over time in order to get better ...

In the past whenever I needed a rotary encoder, I took apart a computer mouse. I do not know if they will meet your requirements, but there's nothing cheaper.

I agree with jhabbott that this is pretty vague. Here are some more ideas: Buy in bulk. In most cases, it's much cheaper per item to buy ten items that it is to buy one. The companies selling you the materials will most likely give you a slightly cheaper price, which they'll sacrifice in return for the larger order. This rule may not apply for any materials ...

In the food industry not many materials are used because of strict policies. The mostly used ones are definitely stainless steels (AISI304/316 and the even better AISI316/L). The other common material is nylon. For applications where only food contact is required(ie containers mostly) also BOPP or other polyolefins are used but they are not common in food ...

Where does the power for a wind turbine come from? Answer - the wind. So how do you get 15kW from the wind rather than 11kW? Answer - you either need a location with a higher wind speed, or you need to pick up more wind, i.e. the blades need to be longer. How does this affect cost? Answer - a longer blade needs more material for its extra length. But then ...

In addition to the above answers: "Standardization", using standard parts throughout the company for similar functions. Increasing commonality between products (like common power boards, common interface boards, common mechanical parts, etc). These would also cut down on design and test efforts, as well as decrease the diversity of inputs and hence ...

There are few generally accepted methods to use to reduce EBOM cost in electronic industry? Group EBOM components using one or both of the following criteria Type of component, (example: capacitors, microprocessor, inductors, resistors, transistors etc) Vendor or Manufacture Then start looking for common components. These could be simple as looking for ...

IBM/Lenovo ThinkPad line is basically the only manufacturer/brand of mobility devices that includes circuitry and software that allows one to vastly prolong battery life of laptops used as stationary workstations by making sure to never charge the battery prior to it being discharged to below 96%, and having options to start charging only when the battery ...

I answered a similar question on SE Sustainable Living recently. Before anyone (including yourself) can answer your question you need to supply some more information. The first thing you need to find out & provide is, what is the heating value of the gas. In metric units this would be the mega joules (MJ) of heat that one cubic metre of gas produces. ...

I suggest investigating copper. Copper has historically been used for coffee rosters. Copper is food safe, provided the food in question is not acidic - pH should be > 6. Otherwise copper would dissolve, copper is a heavy metal with some toxicity. Coffee - the drink - is actually more acidic than that, however in roasting you won'ty have an aquaous phase ...

You could use a potenciometer (some are even less than 1 dolar) without the stopper preferible with multiple revolutions (logarithmic behavior could improve the final resolution), then with some circuite or in the microcontroller code you could configure it to map each potenciometer revolution (or value) to a motor revolution. If your motor has 5000 rpm and ...

It's unclear to me what you consider "expensive", but then you are not even asking for a specific device recommendation, but just how to get started. When I want to see what's available (often even not knowing exactly how the device or item I want is called), I don't hesitate but proceed straight to your usual scumbags - Amazon, AliExpress, ebay. A ...

Cost engineering is "the engineering practice devoted to the management of project cost, involving such activities as estimating, cost control, cost forecasting, investment appraisal and risk analysis." "Cost Engineers budget, plan and monitor investment projects. They seek the optimum balance between cost, quality and time requirements." With ...

There are many points which directly affects the cost of wind turbine. Before installing any wind turbine plant for 1 to 2 years of data analysis of wind density , direction and speed are done by engineer for success of plant which require money and resources. Plants needs lands for installing turbines also land cost depends on market scenario. Height plays ...

As Mahendra Gunawardena said, there's not one universally used method of pricing manufacturing projects, but there are some pretty common facts that result from the economics of the situation. Firstly, if you're talking about small runs at a large company and the design doesn't include anything exotic, the pricing will probably have less to do with the ...

All laptops (and especially cell phones) do "fuel gauge" of the battery. All these mobile devices have a battery charger, which can be started or stopped on command. I don't see why that would be a fundamentally expensive feature. Some of them have software that allows user fine-grained control, and others use only on the functionality built into the OS.

“Vastly prolong battery life” is a subjective statement. A little bit internet research reveals (Laptops with the Longest Battery Life) that a new IBM/Lenovo Thinkpad has an estimated battery life of 15+ hours while a new Toshiba Protégé has 15- hours of battery life. Based on the above link it is safe to assume that IBM/Lenovo Thinkpad have a superior ...

I think this is a question better for the bean counters instead of Engineering. I worked as an Intern at a natural gas fired power plant (about 500 MW total capacity) and profits were the critical factor in determining what happens at a plant. Fuel was a pass-thru cost but capital and maintenance projects were different. Capital was considered re-investment ...

Here is a good short article on the topic. It says that reactors can be refueled in as little as 10 days, but outages typically last an average of two months because non-critical maintenance work is typically differed until a refueling outage. This makes sense, as most systems are safer and easier to work on when they are not running. Standard non-critical ...

Look at the whole product cost, not just the electronic parts. It's quite possible that those represent a relatively small part of the overall cost. For example: What is the cost of assembly? Your picture indicates reasonably modern parts that are amenable to modern volume production techniques. Are these really being used, and used effectively? Are ...
