目的 针对儿童药品安全事故，探究能有效阻止儿童试图进行危险开启行为的药品包装设计策略。方法 以驱力降低理论为依据，分析儿童药品安全事故背后的行为动机，厘清事故发生的概率与内驱力、诱因、习惯强度三者的逻辑关系，针对药品包装中容易对儿童造成误导的影响因子，提出能预防儿童危险行为的安全型药品包装设计思路，最终完成具有可实施性的设计策略构建。结果 驱力降低理论从内驱力、诱因、习惯强度3个方面揭示了儿童药品安全事故的深层原因，其中任一要素的衰减将降低儿童药品安全事故发生的概率。结论 在药品包装中强化视觉、嗅觉、触感、动作和智能化的阻挠设计，为儿童药品安全提供多元化的保障。

The work aims to explore drug packaging design strategies that can effectively prevent children from attempting to engage in dangerous opening behaviors in response to children's drug safety accidents. Based on the theory of driving force reduction, this article analyzed the behavioral motivations behind the safety accidents of children's medicines, clarified the logical relationship between "probability", internal driving force, triggers, and habit strength in the occurrence of accidents. It also identified the factors that could easily mislead children in drug packaging and proposed safety-oriented drug packaging design ideas to prevent dangerous behaviors in children. Ultimately, an implementable design strategy was constructed. The theory of driving force reduction reveals the underlying causes of children's drug safety accidents from three aspects:internal driving force, inducement, and habitual intensity. The attenuation of any element will reduce the occurrence probability of children's drug safety accidents. Therefore, enhancing visual, olfactory, tactile, motor, and intelligent obstruction design in drug packaging provides diversified guarantees for the safety of children's drugs.
