Recently, there has been a global movement toward environmental protection and energy conservation through the design and development of new products in accordance with sustainable utilisation. In this study, rare earth luminescent materials were used owing to their active light emission and reusability. Additionally, solar lightemitting diode lights and car-light reflection were utilised to increase the recognition and reliability of reflective cat eyes. Along with carbon reduction, this can save energy and enhance road safety. This study considered the Theory of Inventive Problem Solving and a literature review to analyse the issues in existing products. Then, expert interviews were conducted to screen projects and develop product design policies. Finally, the ratio of light-storage materials was experimentally determined and the prototypes implemented. This cat's eye addresses the shortcomings identified in previous analyses of existing products. We applied energy storage environmental protection materials, together with material proportioning (which balanced warning efficiency against cost-effectiveness) to develop diversified modular kits; these were flexible in terms of quantity and easily assembled. This study achieved four key objectives: (1) reducing the research and development costs of the manufacturer; (2) offering buyers a diverse suite of products; (3) responding to a need to improve diverse road user safety; and (4) reducing government procurement costs for safety warning products. The results provide a reference for the creative modular design of energy-saving products for public road safety planning in various industries.

Due to the global warming crisis, the spread of various infectious diseases is worsening, with mosquito-borne contagious diseases posing a significant threat. While many residential and public spaces contain plants, often for greening the environment and improving mental and physical well-being, the carbon dioxide released by these plants produces ideal habitats for mosquitoes. Considering the quality of life of urban residents and the development of health-related products simultaneously is an important topic. This study used diverse complementary techniques, such as energy-storing rare-earth luminescent materials, sustainable power generation using plant energy, blue light–emitting diodes, and environmentally friendly fermentation formula, to develop planting products with potential mosquito control functionality. The prototype design for this mosquito-trapping potted plant has been patented. The aim of this paper is to discuss the design principles adopted to improve the defects of existing mosquito-trapping designs, the green energy materials and techniques employed, the architecture configuration of the product prototype, and the test results. By integrating green materials and technology, the prototype can be self-powered without being plugged in to yield conspicuous energy savings. The results showed that the developed multi-function products, combined with the concept of energy sustainability, can improve global public health as well as individuals’ physical and mental health.
