1. INTRODUCTION

   The care and hygiene of infants and toddlers constitute a paramount concern for parents and caregivers worldwide. Among the myriad tasks involved in infant care, the main- tenance of clean and sterilized essentials such as clothes, feeding bottles, and shoes stands as a critical aspect ensur- ing the well-being of young children. However, traditional methods are often cumbersome and time consuming, posing

   challenges for multitasking parents and caregivers. Key fea- tures of the system include rapid drying capabilities, utilizing controlled airflow and temperature to expedite the drying process without compromising fabric integrity. Additionally, the sterilization function employs proven methods to eliminate harmful pathogens, safeguarding the health and well-being of infants. The Automatic Portable Dryer System and Sterilizer Unit offer a groundbreaking solution for maintaining infant hygiene, easing the burdens faced by parents and caregivers worldwide. Through this project, we aspire to contribute to the well-being and safety of infants worldwide, empowering caregivers and parents with a reliable and convenient solution for the essential task of drying and sterilizing baby items. This paper outlines our endeavor to develop an innovative solution aimed at revolutionizing the process of drying and sterilizing baby essentials.

2. MOTIVATION

   Parents are increasingly conscious of creating a safe and germ free environment for their infants. The advanced steril- ization feature assures them that the babys clothes are not only dry but also free from harmful bacteria and pathogens, pro- moting the overall well-being of their child. The space-saving nature of the Automatic Baby Cloth Dryer and Sterilizer Unit makes it an ideal addition to any home, accommodating the needs of modern families with constrained living spaces.

3. OBJECTIVES

   The primary objective of this project is to develop an Automatic Portable Dryer System and Sterilizer Unit within required range.

   1. Design and build a portable device that effectively dries baby essentials (shoes, clothes, feeding bottles) while simultaneously sterilizing them using a UVC lamp.

   2. Ensure the drying process is safe and gentle for the delicate baby essentials.

   3. Eliminate or significantly reduce harmful bacteria and germs on the baby essentials using UVC lamp sterilization.

      The secondary objectives include:

   4. To develop a system that is compact and portable, makes it suitable for travel or outdoor use, allowing parents to maintain hygiene and cleanliness while on the move.

   5. Optimize the systems power consumption to ensure

   sufficient battery life for portable operation.

4. LITERATURE REVIEW

   Safira Fegi Nisrina et al. proposed Sterilizer container using UV-C with an attempt to sterilize goods after we use them. This medical device aims to sterilize goods, either directly or indirectly, with the objective of preventing the adherence of bacteria and viruses to human body and clothing. The Sterilization Container is designed as a space intended to eliminate microorganisms. In the study titled Sterilization Container Using UV-C, UV-C lamps were employed to en- hance the containers functionality, along with the addition of a disinfectant spray activated by a button according to requirements. However, further refinement and development are necessary to achieve optimal results. Future iterations could involve integrating a temperature sensor and updating the IoT interface, with the aim of enhancing user-friendliness and reducing sterilization process duration. [1]

   Asfandyar Khan et al. developed A review of UV radiation protection on humans by textiles and clothing. . This review deals with the pros and cons of ultraviolet (UV) radiation on human beings and the role of textile clothing and the chemicals used for textiles to protect from their harmful effects. UV radiation is categorized into UVA, UVB, and UVC, with UVC and a significant portion of UVB being absorbed by the ozone layer, while UVA penetrates the Earths atmosphere. Prolonged exposure to solar or artificial UV radiation poses considerable risks to human health, with UVR recognized as a significant carcinogen. Excessive sunlight exposure can lead to various types of skin cancer, particularly in individuals with fair skin, affecting areas like the lips, skin squamous cells, basal cells, and cutaneous melanoma. This article aims to present a comprehensive overview of the adverse effects of UVR on human skin, considering factors influencing UV irradiance and the

   protective capabilities of textile clothing. [2]

   Silindir et al. developed a review paper on Sterilization Methods and the Comparison of E-Beam Sterilization with Gamma Radiation Sterilization. The industrial application of radiation has witnessed an annual increase of 10-15 percent over previous years, with more than 180 gamma irradiation facilities operating in 50 countries by 1994. Ionizing radiation serves as the primary mechanism in radio strilization, which is a terminal sterilization method. While gamma irradiation has long been utilized for sterilization, electron beam (e- beam) sterilization represents a relatively recent advancement in sterilization processes for various products, materials, and some pharmaceuticals, albeit without official recognition as a sterilization method yet. Despite being commercialized over 40 years ago, extensive research has been conducted on the impact of e-beam sterilization on pharmaceuticals. The by- products of this process can be analyzed and evaluated for safety using instruments in analytical chemistry. Consequently, for many complex pharmaceutical products unable to with- stand heat or steam sterilization, radio-sterilization emerges as a preferable option. [3]

5. SURVEY

   Drying clothes, especially those of infants and toddlers, poses unique challenges for parents. In this study, we aimed to explore the difficulties faced by parents in this regard and gather insights to inform the development of more effective drying solutions.We conducted a survey involving 10 partic- ipants, specifically targeting parents of babies and toddlers. The survey comprised three main sections: demographic in- formation, challenges encountered during clothes drying, and suggestions for improvement.

   Demographic Information: 70% of respondents reported residing in houses, while 20% lived in apartments, and the remaining 10% resided in flats.

   Challenges Encountered: Rain was cited as a challenge by 10% of respondents, highlighting the weather-dependent nature of outdoor drying. Lack of sunlight was mentioned by 40% of participants, underscoring the importance of nat- ural light for effective drying and sterilization. Improper sterilization emerged as a significant concern, with 80% of respondents expressing apprehension about this issue. Space limitations were identified by 60% of participants, reflecting the constraints faced in urban dwellings where outdoor space is limited.

   Suggestions for Improvement: Portable and compact designs were recommended by respondents, emphasizing the need for flexibility and space-saving solutions. Easy portability was highlighted as a key feature, enabling parents to carry the dry- ing apparatus wherever needed. Efficient drying capacity was desired, with respondents expressing a preference for machines capable of drying larger quantities of clothes simultaneously. Discussions: The survey results underscore the multifaceted nature of

   challenges faced by parents when drying clothes, par- ticularly those of infants and toddlers. The findings highlight the importance of developing innovative solutions that address issues such as space limitations, weather dependency, and sterilization concerns. Portable, compact, and efficient drying solutions emerged as key priorities, reflecting the practical

   needs of parents in todays urban environments.

6. TARGET USERS

   Parents in Urban Areas: Families living in urban environ- ments such as flats, apartments, where space is limited and traditional drying methods may not be feasible.

   New Parents: Specifically, parents of newborns or infants who require frequent washing and drying of baby clothes, blankets, and other essentials, and prioritize hygiene and cleanliness.
