Explain product invention with the help of suitable examples

What will be an ideal response?

Product invention consists of creating something new to meet the needs of consumers in a given country. As markets have gone global, companies ranging from appliance manufacturers and carmakers to candy and soft drink producers have developed products that meet the special purchasing needs of low-income consumers in developing economies. For example, Chinese appliance producer Haier developed sturdier washing machines for rural users in emerging markets, where it found that lighter-duty machines often became clogged with mud when farmers used them to clean vegetables as well as clothes. And solar lighting manufacturer d.light Solar has developed affordable solar-powered home lighting systems for the hundreds of millions of people in the developing world who don't have access to reliable power. d.light's hanging lamps and portable lanterns require no energy source other than the sun and can last up to 15 hours on one charge. The company has already reached 49 million users, is adding 1 million users per month, and plans to reach 100 million users by 2020.
