This paper aims to construct a product form evolution design method integrating the TRIZ contradiction matrix, which is used to eliminate the contradiction between users’ psychological expectations and product engineering requirements, thus simplifying the product form evolution process. We first obtain the psychological needs of users during the whole process of using the product through behavior analysis and then perform an ergonomic simulation of the product to obtain the engineering properties of the product. On this basis, we construct the TRIZ contradiction matrix and solve the contradiction matrix according to the TRIZ theory method. In this way, the ergonomic engineering design attributes of products and the psychological needs of users can be relatively independent, so that the conflict between the ergonomic functional attributes and the psychological needs of users in the design matrix can be effectively transformed into a general TRIZ problem to provide intuitive guidance for product form design. In addition, a detailed design case is provided, which shows that this method can simplify the difficulty and complexity of product form design, and users are more inclined to use the optimized product.

National cultural parks are a new form of tourism in China. These parks focus on cultural heritage. Many studies have examined the cultural ecosystem services (CESs) that parks provide from visitors’ perspectives. However, there needs to be more research on the perceived heterogeneity of CESs among different social groups, especially residents, and the relationship between the supply and demand of CESs. This study uses visitor-employed photographs to reveal the landscape features offered by national cultural parks. This study also analyses the relationship between landscape elements in national cultural parks and CESs, as well as the heterogeneity of users’ perceptions of CESs. The results show that the resident group and visitor group agree on the importance of a sense of place in national cultural parks. However, there are differences between the two groups regarding their perceptions of inspiration, recreation, cultural heritage, and social relations in the parks. Residents are most concerned with the parks’ sense of place and social relations. In contrast, visitors are more interested in inspiration, recreation, heritage, and a sense of place. This study highlights the different needs of residents and visitors from the CESs provided by national cultural parks. It also provides insights for the landscape planning and ecotourism management of cultural heritage-type parks.
