👉 Cottage engineering refers to the informal, self-taught methods and practices used by individuals or small communities to design, build, maintain, and improve their own household appliances, tools, and structures. This approach often relies on traditional knowledge, readily available materials, and practical problem-solving skills passed down through generations. Unlike industrial engineering, which emphasizes large-scale production and standardized processes, cottage engineering is characterized by its adaptability, resourcefulness, and personalization, allowing for unique solutions tailored to specific needs and environments.
