在七年级 WJEC 工程课程中，撰写一份条理清晰、结构合理的报告与制作一个实用模型同样重要。一份组织良好的论文能展示你对设计过程、材料和评估的理解。本文将引导你了解一套可靠的写作框架，并提供一篇完整的范文，帮助你学会如何有效地展示你的工程项目，从而获得更高的分数。
1. Why Engineering Essays Matter | 为什么工程论文很重要
Engineering is not only about making things; it is about explaining why and how you made them. Your written report helps the examiner see your thinking process, from initial ideas to final testing. In WJEC assessments, the written component often carries a significant percentage of the total marks. By mastering a clear framework, you can show evidence of research, design development, practical skills and critical evaluation.
工程不仅仅是制造物品，更在于解释你制造的原因和方式。你的书面报告能帮助考官看到你的思考过程，从最初的构思到最终测试。在 WJEC 的考核中，书面部分通常占总分的很大比例。通过掌握一个清晰的框架，你可以展示研究证据、设计开发、实践技能以及批判性评估。
2. The Standard Report Structure | 标准报告结构
Most Year 7 engineering reports follow a logical sequence: Title Page, Introduction, Research, Design Ideas, Making, Testing, Evaluation, and Conclusion. Think of this as a story that takes the reader on a journey from a problem to a solution. Each section builds upon the previous one, and skipping a part can make your report feel incomplete. Use headings and subheadings to make your document easy to navigate.
大多数七年级工程报告遵循一个逻辑顺序：标题页、引言、研究、设计构思、制作、测试、评估和结论。可以将其想象成一个故事，带领读者从问题走向解决方案。每个部分都建立在前一部分的基础上，跳过任何一部分都会让报告显得不完整。使用标题和小标题可以使你的文档更易于浏览。
3. Title Page and Project Brief | 标题页与项目简介
Your title page should include the project title, your name, class, date, and the WJEC unit title if relevant. Below the title, write a short project brief one or two sentences long that explains what you intend to design and why. For example: 'To design and make a sustainable mobile phone holder from recycled cardboard that can support a phone at a 45-degree angle.' This gives your report a clear focus from the very start.
标题页应包含项目标题、你的姓名、班级、日期以及相关的 WJEC 单元名称（如适用）。在标题下方，用一到两句话写一个简短的项目简介，说明你打算设计什么以及为什么。例如：“利用回收纸板设计并制作一个可持续的手机支架，能够使手机保持 45 度角。”这会让你的报告从一开始就有一个明确的焦点。
4. Writing a Strong Introduction | 撰写有力的引言
The introduction sets the scene. Start by describing the design problem or user need you are addressing. Explain who the target user is and what everyday situation creates this need. State your aim clearly, and briefly outline what your report will cover. A good introduction makes the examiner want to read on because they understand the purpose of your project.
引言部分用于描绘背景。首先描述你正在解决的设计问题或用户需求。解释目标用户是谁，以及什么日常场景产生了这一需求。清楚地陈述你的目标，并简要概述报告将涵盖的内容。一个好的引言会让考官想要继续读下去，因为他们理解了项目的意图。
5. Research and Product Analysis | 研究与产品分析
This section proves you have looked at existing solutions, materials and manufacturing methods before jumping into your own design. Include notes on at least two existing products, describing their features, materials, strengths and weaknesses. Use a table to compare them. Also research appropriate materials, joining techniques and any scientific principles involved, such as forces, levers or stability. Always link your research back to your design specification.
这一部分证明你在着手设计之前已经研究过现有解决方案、材料和制造方法。至少对两款现有产品进行分析，描述它们的特点、材料、优点和缺点。用一个表格来进行比较。同时研究合适的材料、连接技术以及涉及的科学原理，例如力、杠杆或稳定性。始终将你的研究与你自己的设计规格联系起来。
6. Design Ideas and Development | 设计构思与发展
Present at least three initial design ideas with annotated sketches. Annotations should label key features and explain how each idea meets the specification points. After presenting your ideas, choose one to develop further. Justify your choice by comparing the ideas against the specification criteria. Show how you improve the chosen design through modelling, testing small parts or peer feedback. Include a final design drawing with measurements and material details.
至少展示三个初步设计构思，并附上带注释的草图。注释应标明关键特征，并解释每个构思如何满足规格要求。在展示构思之后，选择一个进行进一步开发。通过将各构思与规格标准进行比较来证明你的选择是合理的。展示你如何通过建模、测试小部件或同伴反馈来改进所选设计。附上最终的、带有尺寸和材料细节的设计图。
7. Documenting the Making Process | 记录制作过程
The making section is a step-by-step diary of your practical work. Use photographs or clear diagrams to show each main stage. Write about the tools and equipment you used, the health and safety precautions you took, and any problems you encountered. If you had to change your plan, explain why. This shows you can adapt and solve problems, which is a key engineering skill. Be honest and detailed.
制作部分是你实践工作的分步日记。使用照片或清晰的图示展示每个主要阶段。写下你使用的工具和设备、你所采取的卫生与安全预防措施以及你遇到的所有问题。如果你不得不改变计划，请解释原因。这表明你能够适应并解决问题，这是一项关键的工程技能。要诚实且详细。
8. Testing and Gathering Evidence | 测试与收集证据
Testing must be planned and fair. Describe how you tested your product against the original specification. For example, if your specification said the holder must support 500 g, load it with weights and take a photograph. Record measurements in a table and repeat tests where possible. Note down what worked well and what did not. Use sentences such as 'The phone holder maintained its 45-degree angle for 30 seconds with a 600 g load, exceeding the target.'
测试必须经过计划且公平。描述你如何根据原始规格测试你的产品。例如，如果规格要求支架必须支撑 500 克，那么在上面放置重物并拍照。用表格记录测量数据，并尽可能重复测试。记下哪些方面做得好，哪些不好。使用这样的句子：“手机支架在 600 克负载下保持了 30 秒的 45 度角，超过了目标。”
9. Evaluation: Identifying Strengths and Weaknesses | 评估：找出优缺点
Evaluation is your chance to think critically. Return to your specification and comment on every point. Was the target met fully, partially or not at all? Give reasons. Discuss the strengths of your final product, such as good aesthetics or clever use of materials. Then be open about weaknesses, like a weak joint or inaccurate cutting. Suggest realistic improvements that you would make if you had more time, materials or skills. This honest reflection is highly valued in WJEC engineering.
评估是你进行批判性思考的机会。回到你的规格要求，逐条进行评论。目标是完全达到、部分达到还是根本没达到？给出理由。讨论成品的长处，比如美观性好或材料运用巧妙。然后坦诚地指出缺点，比如接合处不牢固或切割不精确。提出如果你有更多时间、材料或技能，会做出哪些切合实际的改进。这种诚实的反思在 WJEC 工程科目中备受重视。
10. Conclusion and Personal Reflection | 结论与个人反思
The conclusion wraps up your project. Summarise what you achieved and whether you solved the original problem. Keep it brief and do not introduce new information. After the conclusion, add a short personal reflection: What new skills did you learn? What did you enjoy most? What would you do differently next time? This helps build your identity as a developing engineer.
结论部分总结你的项目。概述你所取得的成果，以及你是否解决了最初的问题。保持简洁，不要引入新的信息。在结论之后，添加一段简短的个人反思：你学到了什么新技能？你最享受哪个环节？下次你会有什么不同的做法？这有助于塑造你作为一名成长中的工程师的身份。

Title: Design and Make a Sustainable Mobile Phone Holder from Recycled Cardboard
Student: Alex Chen, Year 7
标题：利用回收纸板设计并制作一个可持续的手机支架
学生：Alex Chen, 七年级
Introduction
Many people watch videos on their phones while sitting at a desk, but holding the phone for a long time is tiring. The problem is that commercial plastic stands are expensive and not always adjustable. My aim is to design and make a phone holder from a single sheet of recycled cardboard, capable of holding a 150 g phone at a 45-degree angle. This report describes my research, design, making, testing and evaluation.
引言
许多人坐在桌前用手机看视频，但长时间手持手机会很累。问题是市面上的塑料支架价格昂贵且角度不一定可调。我的目标是利用一整张回收纸板设计并制作一个手机支架，能支撑 150 克的手机并保持 45 度角。本报告将描述我的研究、设计、制作、测试和评估。
Research
I analysed two existing cardboard stands. Product A used interlocking slots, was very strong but difficult to assemble. Product B used a folding triangle shape, easy to make but unstable with heavier phones. I also researched the material: double-wall corrugated cardboard is strong in compression. I tested the friction between cardboard and a phone case; it was surprisingly high. Therefore, my design must include a lip and a supportive back leg.
研究
我分析了两款现有的纸板支架。产品 A 采用互锁插槽，非常结实但组装困难。产品 B 采用折叠三角形造型，容易制作但放置较重的手机时不稳。我还研究了材料：双层瓦楞纸板抗压强度高。我测试了纸板与手机壳之间的摩擦，发现摩擦力意外地大。因此，我的设计必须包含一个挡边和一条支撑背腿。
Design Ideas
d them against the specification points: cost (free), angle (45° ±5°), stability (no tipping with 200 g), ease of assembly (under 2 minutes) and aesthetics. I chose Idea 3 because it scored highest on stability and aesthetics, and I developed it by adding rounded edges and a cable management notch.
设计构思
我设计了三款草图：构想 1 是一个简单的折叠楔形；构想 2 增加了侧翼以提高稳定性；构想 3 使用活动铰链和一个锁扣片。我根据规格要点对它们进行了评估：成本（零）、角度（45°±5°）、稳定性（200 克负载下不倾倒）、组装简易度（2 分钟内）和美观性。我选择了构想 3，因为它在稳定性和美观性上得分最高，我通过增加圆角和理线槽对其进行了改进。
Making
I transferred the final design onto a flat sheet of recycled cardboard. I used a steel ruler and a craft knife with a cutting mat, always cutting away from my body. I scored the fold lines lightly to create clean hinges. I encountered a problem when one tab snapped; I strengthened it by adding a second layer of card glued with PVA. The whole process took about 45 minutes.
制作
我将最终设计描绘在一张平整的回收纸板上。我使用钢直尺、美工刀和切割垫，始终朝远离身体的方向切割。我轻轻地划出折线，以形成整洁的铰链。我遇到一个问题，一个锁片断裂了；我通过用白乳胶粘贴第二层纸板对其进行了加固。整个过程大约花了 45 分钟。
Testing
Test 1 (Angle): I measured the angle with a protractor; it was exactly 45°. Test 2 (Load): I placed a 200 g weight on the stand; it held for over a minute without tipping. Test 3 (Durability): I folded and unfolded the stand ten times; the hinge showed slight wear but remained functional. All results met the specification.
测试
测试 1（角度）：我用量角器测量了角度，正好是 45°。测试 2（负载）：我在支架上放置 200 克重物，它保持了一分钟多没有倾倒。测试 3（耐用性）：我将支架折叠展开十次，铰链出现轻微磨损但仍能使用。所有结果均符合规格要求。
Evaluation
The product fully met the angle and load targets. The aesthetics were improved by the rounded edges. However, the hinge became weaker after repeated use; this could be solved by reinforcing it with fabric tape in the future. The cable management notch was very useful and well received by my classmates. If I were to repeat the project, I would experiment with a wooden dowel hinge for longer life.
评估
该产品完全达到了角度和负载目标。圆角设计提升了美观性。但是，铰链在反复使用后变弱了；将来可以用布基胶带加固来解决这个问题。理线槽非常实用，受到了同学们的好评。如果重做这个项目，我会尝试用木销铰链以获得更长的使用寿命。
Conclusion
I successfully designed and built a functional, sustainable phone holder that solves the identified problem. I learned how to score and bend corrugated cardboard accurately, and I now understand the importance of testing prototypes early. This project has increased my confidence in working with recycled materials.
结论
我成功地设计并制作了一个实用、可持续的手机支架，解决了最初发现的问题。我学会了如何精确地划线和弯折瓦楞纸板，并且现在理解了尽早测试原型的重要性。这个项目增强了我使用回收材料进行制作的信心。
12. Common Mistakes to Avoid | 需要避免的常见错误
Many students lose marks by missing out the research section, writing very little evaluation, or not including any photographs. Another mistake is writing vague statements like 'It was good' without using data or referring to the specification. Always check your spelling of technical terms such as 'corrugated', 'aesthetic' and 'specification'. Finally, do not forget to label your sketches and list your sources of information.
许多学生因遗漏研究部分、只写很少的评估或不附任何照片而失分。另一个错误是写出“这很棒”之类的模糊表述，却没有引用数据或参考规格。务必检查技术术语的拼写，如 “corrugated”（瓦楞的）、“aesthetic”（美观的）和 “specification”（规格）。最后，不要忘记给你的草图加上标注，并列出你的信息来源。
