2. Choosing the Right Competition | 选择适合的竞赛
Select a competition that matches your team’s interests, resources, and the CIE Engineering syllabus topics, such as forces, materials, electronics, or mechanics. For instance, if you enjoy aerodynamics and manufacturing, F1 in Schools might be ideal. If you prefer programming and sensors, a robotics challenge suits better.
选择一项与团队兴趣、资源以及 CIE 工程课程大纲（如力、材料、电子或机械等主题）相匹配的竞赛。例如，如果喜欢空气动力学和制造，F1 in Schools 可能很理想。如果偏爱编程和传感器，则机器人挑战赛更合适。
Check age categories, team size limits, and equipment requirements. Some competitions provide kits; others require self-sourced materials. Always review the official rulebook and past winning entries to understand the level of complexity expected.
检查年龄分组、团队人数限制和设备要求。有些竞赛提供套件；另一些则需要自行采购材料。务必仔细阅读官方规则手册和历届获奖作品，以了解预期的复杂度水平。
Discuss with teachers and mentors whether the competition aligns with your school’s timetable and budget. A well-supported entry prevents last-minute stress.
与老师和导师讨论该竞赛是否与学校的时间安排和预算相匹配。有良好支持的参赛项目可以避免最后一刻的压力。
3. Building Your Team and Assigning Roles | 组建团队与角色分配
A typical team has 3–6 members. Diversity in skills is key: include roles like project manager, design engineer, manufacturing lead, testing specialist, and graphic designer/documenter. Each person should take ownership of a domain but also support others.
一个典型的团队有 3 到 6 名成员。技能多样性是关键：包括项目经理、设计工程师、制造负责人、测试专员和平面设计师/文档员等角色。每个人都应负责一个领域，同时也要支持他人。
Use the CIE Engineering focus on systems and processes to define responsibilities clearly. Hold regular meetings, set agendas, and take minutes. This mirrors real engineering project management and is often rewarded in competition documentation.
借助 CIE 工程学注重系统和流程的特点，清晰界定职责。定期召开会议，设定议程并做会议记录。这反映了真实的工程项目管理，在竞赛文档中往往加分。
Encourage open communication and conflict resolution. A team that works well together can overcome technical challenges more easily than a group of brilliant individuals who cannot collaborate.
鼓励坦诚沟通和冲突解决。一个合作默契的团队比一群无法协作的天才个体更容易克服技术困难。
4. Project Planning and Time Management | 项目规划与时间管理
Start by breaking down the competition timeline into phases: research, ideation, design, prototyping, testing, refinement, documentation, and presentation practice. Allocate weeks or days for each phase depending on the final deadline.
首先将竞赛时间线分解为多个阶段：研究、构思、设计、原型制作、测试、改进、文档编写和展示练习。根据最终截止日期为每个阶段分配周数或天数。
Use a Gantt chart or a simple shared spreadsheet to track tasks. Identify critical milestones, such as completing the CAD model or first working prototype. This helps the team stay on track and reduces last-minute panic.
使用甘特图或简单的共享电子表格来跟踪任务。确定关键里程碑，比如完成 CAD 模型或第一个可运行的原型。这有助于团队按计划推进，减少最后一刻的慌乱。
Factor in time for unexpected failures. Prototypes rarely work perfectly the first time. Building a buffer into the schedule for redesigns and material reorders prevents major setbacks.
为意外失败预留时间。原型很少一次就完美运行。在日程中加入缓冲时间用于重新设计和材料重新订购，可以防止重大挫折。
5. Research, Design and Optimisation | 研究、设计与优化
Gather scientific principles related to your challenge. For a bridge, study forces, tension, compression, and material properties. For a car, explore drag, mass, and energy transfer. Use your CIE Engineering textbook as a foundation and supplement with online resources and maker forums.
收集与挑战相关的科学原理。对于桥梁，研究力、张力、压力和材料特性。对于小车，探索阻力、质量和能量转换。以 CIE 工程教科书为基础，并用在线资源和创客论坛加以补充。
Sketch multiple design concepts and evaluate them using a decision matrix. Criteria might include weight, strength, cost, manufacturability, and aesthetics. The matrix helps the team choose the most promising design objectively, rather than relying on gut feeling alone.
绘制多个设计概念草图，并使用决策矩阵进行评估。标准可能包括重量、强度、成本、可制造性和美观度。矩阵有助于团队客观地选择最有前景的设计，而不仅仅依靠直觉。
Use CAD software (such as Tinkercad, Fusion 360, or SolidWorks if available) to create a digital model. Simulate forces or run basic analyses if the software allows. Digital models reduce material waste and help identify interference issues before physical building.
使用 CAD 软件（如 Tinkercad、Fusion 360 或 SolidWorks，如果有的话）创建数字模型。如果软件允许，可以模拟受力或运行基础分析。数字模型可以减少材料浪费，并在实体搭建前发现干涉问题。
6. Prototyping and Testing | 原型制作与测试
Produce a first prototype using low-cost materials like cardboard, 3D-printed parts, or laser-cut components. This ‘rough and ready’ model allows you to verify dimensions, fit, and basic function before investing in final materials.
使用低成本材料（如纸板、3D 打印零件或激光切割部件）制作第一个原型。这个“简陋但可用”的模型能让你在投入最终材料之前验证尺寸、配合和基本功能。
Test the prototype against the competition’s performance metrics. For a vehicle, measure speed, distance, or payload capacity. For a structure, test load-bearing until failure. Record all data meticulously; use tables and graphs that can later appear in your portfolio.
根据竞赛的性能指标测试原型。对于车辆，测量速度、距离或承载能力。对于结构，测试承重直至破坏。仔细记录所有数据；使用表格和图表，以便日后收入作品集。
Iterate based on test results. Apply the design-build-test cycle repeatedly. Each iteration should bring measurable improvement. Document changes and the reasoning behind them – this shows judges a methodical engineering approach.
根据测试结果进行迭代。反复应用设计-搭建-测试循环。每次迭代都应带来可衡量的改进。记录更改及其背后的原因——这向评委展示了有条不紊的工程方法。
7. Technical Documentation and the Portfolio | 技术文档与作品集
Most competitions require an engineering portfolio or design journal. This is not just a final report; it should capture the entire journey, including initial sketches, meeting notes, failed prototypes, and data analysis. Judges want to see your thinking process.
大多数竞赛要求提交工程作品集或设计日志。这不仅仅是一份最终报告，它应记录整个旅程，包括初始草图、会议记录、失败的原型和数据分析。评委希望看到你的思维过程。
Organise the portfolio logically: title page, table of contents, problem definition, research, design evolution, manufacturing details, test results, and conclusion. Use clear headings, annotated photos, and properly labelled graphs (e.g., ‘Figure 1: Load vs Deflection’).
有逻辑地组织作品集：封面、目录、问题定义、研究、设计演变、制造细节、测试结果和结论。使用清晰的标题、带注释的照片和正确标记的图表（例如“图 1：载荷与挠度”）。
Ensure all written sections are free of spelling and grammar errors. Have a teacher or team member proofread. In international competitions, clarity of technical English is often a scoring factor.
确保所有书面部分没有拼写和语法错误。请老师或团队成员校对。在国际竞赛中，技术英语的清晰度往往是评分因素之一。
8. Presentation and Communication Skills | 演讲与沟通技巧
The oral presentation is your chance to bring the project to life for the judges. Prepare a structured 5–10 minute pitch: hook audience with a problem statement, explain your design journey, highlight innovative features, and share key results and lessons learned.
口头展示是你向评委生动呈现项目的机会。准备一个结构清晰的 5-10 分钟演讲：用问题陈述吸引听众，解释设计历程，突出创新特色，并分享关键结果和经验教训。
Use visual aids such as slides, a physical prototype, and a poster. Rehearse multiple times as a team, ensuring each member speaks confidently and transition between speakers is smooth. Time your presentation and cut content that does not add value.
使用视觉辅助工具，如幻灯片、实体原型和海报。以团队形式多次排练，确保每位成员都能自信地发言，且成员之间的过渡顺畅。计时演练，删除不增加价值的内容。
Anticipate questions. Judges often ask about design choices, mathematical calculations, material selection, or what you would do differently. Prepare answers in advance and practise in mock Q&A sessions. Stay calm and refer to data when possible.
预判提问。评委常问及设计选择、数学计算、材料选择或你会如何改进。提前准备答案，并在模拟问答中练习。保持冷静，尽可能引用数据作答。
9. Competition Day Practical Tips | 比赛日实用技巧
Pack a ‘competition kit’ that includes your prototype, spare parts, basic tools, glue, tape, batteries, chargers, a printed copy of rules, portfolio, and any required documentation. Arrive early to set up and test the environment.
准备一个“竞赛工具箱”，包含原型、备件、基本工具、胶水、胶带、电池、充电器、纸质版规则、作品集和所有必需文件。提前到场进行布置和环境测试。
During performance runs, follow a checklist to avoid skipping steps. If something breaks, stay composed and use your prepared spares and repair strategy. Judges observe how teams handle pressure, not just the device’s score.
在性能运行期间，照着检查清单操作，避免漏步。如果某物损坏，保持冷静，使用准备好的备件和维修策略。评委不仅关注设备得分，也观察团队如何应对压力。
Network with other teams. Observe their designs; ask respectful questions. Competitions are learning experiences, and you can gain ideas for future projects while making friends across schools and countries.
与其他团队交流。观察他们的设计；有礼貌地提问。竞赛是学习经历，你可以从中获得未来项目的灵感，同时结交来自不同学校和国家的朋友。
10. Post-Competition Reflection and Improvement | 赛后反思与持续改进
Regardless of the outcome, hold a formal debrief with your team. List what worked well, what went wrong, and what you would do differently. This reflection aligns with the CIE Engineering cycle of evaluation, which is vital for long-term growth.
无论结果如何，与团队进行一次正式复盘。列出哪些做得好、哪些出了问题以及你会如何改进。这种反思与 CIE 工程学的评估循环相契合，对长期成长至关重要。
Update your portfolio with judges’ feedback and your own reflections. This living document becomes a powerful resource for next year’s competition or for showcasing in personal statements for school applications.
将评委的反馈和自身反思更新到作品集中。这份活文档将成为明年竞赛的有力资源，或用于学校申请的个人陈述展示。
Stay engaged with engineering communities. Join school STEM clubs, online forums, or participate in outreach events. The skills you build through competitions—teamwork, design thinking, and resilience—are lifelong assets.
