How to generate new business ideas

From 'made in space' products to underwater restaurants and hotels, new and unique business ideas are always fascinating to investors. This is because innovative business ventures not only deliver the return on invested capital, but also provide the businesspersons with the feeling of being a trailblazer, or trendsetter in the market, compared with traditional run-of-the-mill businesses.
Many small investors find it risky to try a new 'out of the box' business idea, but these underlying risks can be mitigated after evaluating the socio-economic and cultural compatibility of the idea where it is going to be practically implemented.
Essentially, you have to show basic creativity to find out 'real, but un-served need' of the consumers, which is not being catered by the existing companies. For example, many popular brands of baby nappies or diapers are available in the market made as per predefined standards. Nevertheless, these readymade nappies do not fit every child accurately, as not being tailor-made or fully customised as per each baby's requirements. This problem may lead the business opportunists to a new business idea of making customised baby nappies.
If you are a keen observer, you can quickly generate a valid business idea. For example, absence of a decent public toilet system is a common problem never addressed by the private companies in our cities. Run by government departments, we can find public toilets at some locations that appear to be 'not user friendly,' offering totally unhygienic and sullied environment, and very limited space, including the universal lack of toilet papers, water and the rest of the lavatory accessories. Especially for women, these public toilets are not usable at all, and no consideration is given to children, disabled and old age people during construction of toilets at public places. Well-equipped with essential toiletries, private firms can introduce a paid service of 'wheeled mobile toilets' in our cities, offering sanitised and hygienic environment to all age groups.  
Let us look into other untapped ideas. The material of 'lawn' is mostly considered as women's clothing fabric, and no such lawn fabric are offered exclusively for men. Local businessmen can think of introducing a 'gentlemen's lawn' as a primary fabric for men.
Businesses do need modification and alteration, according to different business environment, societal values and socioeconomic trends. For example, slimming centres serve those men and women who want to shed their excessive weight, but there is no facility offered to those underweight people who are much too skinny and thin, and want to gain the missing body mass. This approach also leads us to open an exclusive restaurant for the health conscious people where they can order anything starting from boiled potatoes to high fibre cereals, salmon fish and food cooked in olive oil etc. If implemented, this concept will transform restaurants into health awareness centres, and the regular waiters will now work as health advisors and food consultants.
Our country faces acute shortages of energy resources. This energy crisis offers business opportunists to introduce those standard machines in the local market which can be easily run without using gas or electricity, and could work as makeshift alternatives of power-run machines, especially during power outages and load-shedding. During rainy seasons, to drain out an enormous amount of water gathered in the courtyard, basement, and other areas of our homes and buildings, we can think of manual water drainage pumps.
Tapped or untapped, new business ideas offer a ray of hope even in the depressed economic conditions.
