Design instructions for cigarette cases:
Early market user research and mining problem points, demand points as a horizontal core design purpose, and combined with the World Environmental Health Organization background trend as a vertical dimension, together to define specific product solutions strategy. The vertical core purpose is to enhance the environmental awareness of the majority of smokers and contribute to the green ecology. The horizontal core purpose is to solve the problems and demand points caused by smokers in the whole process of smoking.

Design innovation points:
1. Redefine the use boundary of cigarette cases, lighters and ashtrays according to the future design trend, and solve the inconvenience of smokers in the actual process of smoking through design integration.
2. Digging deeply into the subconscious idea of smokers littering cigarette butts and seeking the essence of the problem, introducing "ashtrays" into the product to store cigarette butts and soot. In this way, smokers are guided to develop good smoking habits and environmental awareness, which is in line with the goal of environmental protection.
3. Follow the concept of green and sustainable design-3R concept, namely: small amount, reuse and resource regeneration. The lighter in the integrated cigarette case breaks the traditional way of replenishing gas and liquid, through modular exchange of butane liquid, breaks the way of throwing the lighter when it is used up, and optimizes the process of user replenishing butane.

Product description:
1. The design orientation of the product is: multi-functional modular combination, light luxury and portable, integrated integration, green and natural for environmental protection
2. Adopt innovative folding form to enable users to flexibly use the functions of the product
3. The smoke and ignition functions are integrated on the same slider to optimize the man-machine use process of the product
4. Increase the use of rounded corners on the corners of the cube. The combination of square and round and side hemming conforms to the trend of modern design style.
5. The original shape of the product is retained as much as possible in the overall design layout, and the matching of CMF is also unified, which conforms to the style concept of integrated design.
