📚 IGCSE CIE Engineering: Case Study Practical Drill | IGCSE CIE 工程：案例分析实战演练
This article provides a hands-on walkthrough of tackling case studies in IGCSE CIE Engineering. It guides you through each stage of the design process using real-world examples and interactive exercises, helping you master the skills needed to excel in your coursework and exams.
本文提供了一次 IGCSE CIE 工程案例研究的动手实战演练。它通过真实世界的案例和互动练习，引导你经历设计过程的每个阶段，帮助你掌握在课程作业和考试中脱颖而出所需的技能。
1. Understanding Engineering Case Studies | 理解工程案例研究
An engineering case study involves investigating a design problem, developing solutions, and evaluating the outcome. It mimics what professional engineers do when they create new products or improve existing ones. In the IGCSE exam, you may be asked to analyse a given scenario, suggest improvements, or even design a complete system from scratch.
工程案例研究包括调查设计问题、开发解决方案并评估结果。它模仿专业工程师在创造新产品或改进现有产品时所做的工作。在 IGCSE 考试中，你可能会被要求分析给定场景、提出改进建议，甚至从零开始设计一个完整的系统。
Key skills evaluated include: creative thinking, technical knowledge, application of maths and science, and the ability to communicate ideas clearly through sketches and written explanations.
评估的关键技能包括：创造性思维、技术知识、数学和科学的应用，以及通过草图和书面说明清晰地表达想法的能力。
2. Problem Definition and Requirements | 问题定义与需求
Every case study starts with a clear problem statement. For example, ‘Design an automatic door system for a busy shopping centre entrance that is safe, reliable, and energy-efficient.’ You must then identify the user needs and constraints: who will use it, where it will be installed, budget limits, environmental conditions, etc.
每个案例研究都从明确的问题陈述开始。例如，“为繁忙的购物中心入口设计一个安全、可靠且节能的自动门系统。”然后你必须识别用户需求和约束条件：谁将使用它、安装在哪里、预算限制、环境条件等。
Write down the problem in your own words and list all requirements. Use the acronym ACCESS FM (Aesthetics, Cost, Customer, Environment, Safety, Size, Function, Materials) to ensure you do not miss any aspect.
用你自己的话把问题写下来，并列出所有需求。使用
