With the improvement of the Chinese family′s quality of life, there is a demand to get close to nature and relax physically and mentally. Outdoor camping has become a popular leisure choice due to its ability to get in touch with nature in depth and get away from the hustle and bustle. Parents focus on the children′s outdoor experience and nature education, and parent-child tours promote the development of the camping market. Chinese National and local governments have launched a series of policies to support the development of the outdoor camping industry, proposing to support the construction of camping sites and encouraging the use of open space to create camping and recreational areas to provide protection and guidance for the development of the industry.Based on the Double Diamond Model Theory, this research analyzes the advantages and disadvantages of existing products in the current market; most camper products are designed with storage as the primary function, which neglects the interactive entertainment experience of children in the outdoor open environment. Then, it collects users′ demands for children′s camper products and organizes the results by adopting the user interview method and the user journey map to propose an innovative children′s camper design strategy. Traditional campers find it difficult to meet children′s specific needs in the vast outdoor space and their interactive entertainment modes; children in the outdoor space need certain aids in the facilities to bring them a more enjoyable outdoor entertainment experience. Therefore, this study proposes an innovative design concept for children′s campers to create a better camping experience for children and meet their interactive entertainment needs. Provide children with meaningful interactive function design so that children in the outdoor space can feel nature, sports, and exercise, learn knowledge, and improve children′s comprehensive quality of life.
