儿童是一个家庭的希望和未来，儿童安全关系着千家万户。伤害是儿童安全的重要威胁。家庭是儿童生活的主要场所，有一半以上的儿童伤害发生在家庭环境中。学龄前儿童由于居家时间较长，儿童居家安全伤害病例的发生率更高。然而，针对儿童跌落、烫伤、误食等儿童居家场景中常见的伤害事件的防护，现有解决方案一般为人工看护+物理防护产品+智能防护产品。但家长无法每时每刻看护儿童，在生活中总存在着的“做饭时间”往往是儿童安全防护的缺口。物理防护产品主要针对环境隐患，而现有的智能看护产品，主要是摄像头类产品，无法监控活泼好动的学龄前儿童。因此，研究者期望引入具有自主移动能力的机器狗为儿童安全提供新的解决方案。

本文对学龄前儿童的发展特征和家庭特点进行了国内外研究分析，总结了学龄前儿童的特点对产品设计的指导原则和学龄前儿童的家庭特点。同时，由于伤害事件具有一次性和伤害性的性质，研究者决定使用叙事理论来进行儿童居家伤害事件的研究。

在调研阶段，本文利用桌面调查法分析了59个案例，分析总结了10类伤害事件发生时的伤害概况、看护状态、家长心理、儿童心理和伤害处理，并总结了伤害事件的三个主要阶段，即伤害预防阶段、日常看管阶段和事后处理阶段。然后，本文利用问卷调查法共收集了105份问卷。从中发现，在伤害情况方面，一年内儿童居家伤害发生率较高，最为常见的伤害类型有摔伤、动物伤、钝器伤、烧/烫伤和刀/锐器伤，伤害高发的场所有客厅、餐厅和卫生间，不同的伤害类型在特定的场景中较为高发；家长的学历水平和家庭孩子的数量都对伤害发生率有显著影响；家长认知和行为方面，家长普遍都能认识到对儿童进行安全教育具有必要性，家长对儿童的安全需要比较高，然而在实际养育过程中存在看护时间不足、科学养育知识储备不足的问题；在家庭环境方面，各个家庭中仍然存在许多的安全隐患；在对安全产品的使用上，大部分家长都会购买物理或智能防护用户，儿童摄像头使用率接近一半。最后利用访谈法，深入了解普通家长的日常看护情况，伤害事件经历和处理方法，研究发现幼儿的日常生活总会面临独处时光，儿童家长普遍会使用摄像头来进行辅助监控，但对于AI相关功能的了解和使用不多。

根据调研结果，基于叙事的方式对伤害事件的典型人、物和环境进行的叙事建构，以此为依据指导后续的产品设计。最后，我们将理论研究应用到实践上，结合AI+机器狗的技术手段，设计一款新型的儿童居家看护产品，给儿童居家安全产品提供新的解决思路。

Children are the hope and future of a family, and the safety of children is crucial for countless households. Injuries represent a significant threat to the safety of children. The family is the primary setting for a child's life, with over half of childhood injuries occurring within the home environment. Existing solutions for preventing common injuries in the home, such as falls, burns, and ingestion accidents, typically rely on a combination of manual supervision, physical protective products, and smart safety products. However, parents cannot watch over their children at all times, and certain daily activities like cooking create safety gaps for children. Physical protective products mainly address environmental hazards, while current smart safety products, primarily camera-based, are unable to monitor active and mobile preschool children effectively. Hence, the researchers aim to introduce autonomous mobile robotic dogs as a new solution for child safety.

This paper conducts a comprehensive analysis of the developmental characteristics of preschool children and their family dynamics through domestic and international research. It summarizes the characteristics of preschool children that guide product design principles and the family characteristics of preschool children. Recognizing the episodic and injurious nature of injury events, the researchers opt to employ narrative theory to study childhood home injuries.

In the research phase, this paper employs desktop investigation methods to analyze 59 cases, summarizing injury profiles, supervision statuses, parental psychology, child psychology, and injury management for ten types of injury events. The paper identifies three main stages of injury events: injury prevention, daily supervision, and post-incident handling. Subsequently, 105 questionnaires are collected through a questionnaire survey. The findings indicate a relatively high incidence of childhood home injuries within a year, with the most common injury types being falls, animal bites, blunt force injuries, burns/scalds, and sharp object injuries. Injuries occur most frequently in specific locations such as the living room, dining area, and bathroom, depending on the injury type. Parents' education levels and the number of children in the household significantly impact injury rates. While parents generally recognize the importance of child safety education and have a high concern for their children's safety, they face challenges related to inadequate supervision time and a lack of knowledge about scientifically informed childcare practices. Many households still have various safety hazards. In terms of safety product usage, the majority of parents purchase physical or smart protective products, with nearly half of them using child cameras.

Finally, through interviews with ordinary parents, the paper gains deeper insights into their daily supervision practices, experiences with injury incidents, and response strategies. It is observed that young children often have unsupervised moments in their daily lives, and parents commonly use cameras for supplementary monitoring. However, there is limited understanding and use of AI-related functions.

Based on the research findings, a narrative-based approach is employed to construct narratives of typical persons, objects, and environments involved in injury incidents, serving as the basis for guiding subsequent product design. Ultimately, the paper applies theoretical research to practice by combining AI and robotic dog technology to design a novel child home care product, offering fresh perspectives for child home safety products.
