01 — Services
What you can hand over. 你可以交出去的部分。
Design设计
Bring an idea, a sketch, or a drawing. Get the design ready to be made.带来一个想法、一张草图，或一份图纸。换回一个可以拿去做的设计。
Prototype打样
A real part you can hold, test, and refine — before tooling.一个能拿在手上、能测、能改的实物——在开模之前。
Source选厂
Find suppliers. Send RFQs. Compare pricing, capabilities, and lead times.找供应商。发询价。比价格、能力、交期。
Supply chain供应链
Find suppliers for parts or assembly. Review quotes and find savings.为零件或组装找供应商。审报价，找出能省钱的地方。
02 — In practice
Thinking Beyond Design 不止于设计
Part — acoustic cover for a filter housing, sheet metal 零件——滤波器外壳的隔音罩，钣金件
Job — 20 pieces, sample stage 订单——20 件，打样阶段
1,600 → Sample cost 230 RMB — 样品价 230 元 RMB sample cost for 20 pieces 20 件的样品费：1,600 → 230 元
The problem — The original quote was RMB 1,600 for 20 pieces, based on a stamping process. No design-for-manufacturing review had been carried out. 问题：原来的报价按冲压工艺做，20 件 1,600 元。没有做过任何可制造性评审。
The DFM — The part was redesigned for sheet-metal bending, with reliefs added at all four corners. Material, thickness, and clearances remained unchanged. DFM：把零件改成钣金折弯，四个角都加了让位。材料、板厚、间隙保持不变。
The supplier — A manufacturer with the right equipment and existing production experience was selected. No new die was required. 供应商：选定了一家设备合适、已有生产经验的制造商。不需要新开模。
Cost is shaped at the design stage. 成本在设计阶段就被决定了。
03 — Process
Five steps. From idea to production. 五步，从想法到生产。
Share Your Idea分享你的想法
Send a drawing, a photo, or a brief description. Include the quantity and key requirements.发一张图、一张照片，或一段描述。写清数量和关键要求。
Manufacturing Review制造评审
Assess manufacturability, identify DFM opportunities, and explore suitable production options.评估可制造性，找出 DFM 空间，探索合适的生产方式。
Quotation & Approval报价与确认
Receive a clear scope, quotation, and timeline. Nothing moves forward without your approval.收到明确的范围、报价和周期。你确认之前，不往下走。
Prototyping打样
Get a physical sample to review. Refine the design and address issues before production.拿到实物样品来看。改设计、解决问题，再进生产。
Production生产
The selected supplier handles production and assembly.选定的供应商完成生产与组装。
04 — Limits
Four things outside the scope. 四件不在范围内的事。
Firmware and PCB design.固件和 PCB 设计。
Simple soldering is fine.
! Circuit design, PCB layout, and firmware development remain with your electronics engineer.简单焊接可以。电路设计、PCB 布局、固件开发，留给你的电子工程师。
Product certification (CE, FCC, UL).产品认证（CE、FCC、UL）。
Product preparation is part of the work.
! Testing, certification, and regulatory compliance remain your responsibility.产品准备工作是工作的一部分。测试、认证和法规遵从，仍然是你的责任。
Complex organic surfaces.复杂有机曲面。
Industrial design is part of the work — enclosures, form, and CMF.
! Complex organic shapes are better handled by a specialist industrial design studio.工业设计是工作的一部分——包括外壳、造型、色彩、材料和表面处理。复杂的有机形状，交给专业的工业设计工作室更合适。
Shipping and logistics.运输与物流。
The factory quotes the part; how it leaves is decided separately.
! Freight, export documents, customs, and insurance are arranged by you or your forwarder.工厂报的是零件价格；货怎么出去单独决定。运费、出口文件、报关和保险，由你或你的货代安排。

06 — Pricing
Clear scope. Clear pricing. 范围清楚，价格清楚。
Each service is priced separately. What you pay the supplier is always separate from what you pay me. 每项服务单独计费。付给供应商的钱，和付给我的钱，始终是两笔。
Engineering Review工程评审
Two levels of review, both for one part.两级评审，都针对单个零件。
Quick Check — $50快速检查
- Basic manufacturing feasibility of one part单个零件的基础可制造性判断
- 1–2 specific improvements1–2 条具体改进建议
- A quick check, not a full DFM analysis是快速检查，不是完整的 DFM 分析
- 3 business days3 个工作日
DFM Report — $150DFM 报告
- Detailed design-for-manufacturing analysis of one part单个零件的完整可制造性分析
- Recommended design changes建议的设计改动
- Process and material options工艺与材料方案
- Estimated cost impact, using a supplier quote for the part where one is available预估成本影响；如已取得该零件的供应商报价，用它来估算
- 5–7 business days5–7 个工作日
The quote is for costing only. Supplier search, RFQs, and supplier coordination are Supplier Sourcing.这里的报价只用于成本估算。寻找供应商、发 RFQ、供应商协调属于「供应商寻源」。
The full Engineering Review fee is credited toward your first engineering service fee. 工程评审费用将在首笔工程服务费中全额抵扣，不适用于供应商生产费用及其他供应商付款。
Prototyping打样
Two ways to get a sample.两种拿到样品的方式。
Made here — From $100 / part我自己做 · 每件 100 美元起
- 3D printing and basic bench work, done in-house内部完成 3D 打印和基础手工
- Small parts only. No factory tooling, no production capacity.只做小件。没有工厂产能，也不做模具。
- $100 is the starting price. The actual price depends on size, material, complexity, and the work required.100 美元是起步价；实际价格按零件尺寸、材料、复杂程度和具体工作量确定。
Made by a supplier — $35 / hour工厂做 · 每小时 35 美元
- The supplier quotes and makes the sample由工厂报价并打样
- You pay the supplier for the part, directly零件费用直接付给工厂
- $35 / hour is my engineering service fee for coordinating it每小时 35 美元是我协调这项工作的工程服务费
Supplier Sourcing & Production供应商寻源与生产
Sourcing happens before the order. Production happens after.寻源在订单确定之前，生产在订单确定之后。
Supplier Sourcing — $35 / hour供应商寻源 · 每小时 35 美元
My engineering service fee. Not a supplier production cost.这是我的工程服务费，不是供应商生产费用。
Billed on actual working time. Minimum 1 hour.按实际工作时间计费，最低 1 小时。
- Supplier identification and screening供应商寻找与筛选
- RFQ preparation and follow-upRFQ 准备与跟进
- Quotation and capability comparison报价与能力比较
- Early technical communication前期技术沟通
Production — quoted by the factory生产 · 由工厂报价

Before Work Begins开工之前
Scope, estimated working hours, deliverables, and fees are agreed in advance. No extra work or cost is added without your approval. 范围、预计工时、交付内容和费用在开工前确认。未经你同意，不增加额外工作或费用。
07 — Contact

Tell me a little about your project. A drawing or photo is welcome, but not required. 说说你的项目。有图纸或照片更好，没有也可以。
Graded on a real job. 用一份真实的活打分。
Technical Product Designer, field Machinery and Plant Design, examined by IHK zu Leipzig. The examination is built around a work assignment: a task arrives, nobody tells you which process to use, and you have to make it manufacturable and cost it. 技术产品设计师，机械与设备构造方向，由莱比锡工商大会（IHK）考核。考试围绕一份工作任务：任务来了，没人告诉你该用什么工艺，你得把它做成能制造的，并且算出成本。
