以下是九号创新客户咨询频率最高的工业设计常见问题，涵盖合作全流程，若有其他疑问，可直接联系我一对一解答。
1、工业设计公司一般怎么收费？
工业设计费用根据产品品类、设计复杂度、是否包含结构 + 建模 + 量产跟进而定。我们可根据你的产品需求提供透明报价和定制方案，无隐藏费用。
2、做一款产品设计大概需要多长周期？
一般外观设计 7-15 个工作日；外观 + 结构全案设计一般 20-40 个工作日；复杂小家电、带功能结构的产品周期会适当延长，全程可同步进度、按需修改，不额外拖延时间。
3、外观设计和结构设计有什么区别？
外观设计主打产品造型、配色、手感、视觉美学，核心是 “好看 + 好握”；结构设计负责内部零件堆叠、卡扣、装配、防水、散热及适配开模量产，核心是 “好用 + 能造”，一款成熟产品两者缺一不可。
4、没有完整想法，只有大致创意可以设计吗？
可以。我们支持从模糊创意、手绘草图、功能想法起步，根据市场竞品分析、创意落地、造型优化，甚至提供多版方案供选择，从零打造完整产品方案。
5、设计完可以对接工厂量产吗？
支持一站式落地！设计完成后提供完整工程图纸、渲染图、结构图，可协助对接长期合作的优质工厂，全程跟进开模、打样、试产调整，避免 “设计好看但无法量产” 的行业痛点。
6、初创企业适合做专属工业设计吗？
非常适合。差异化设计能避开同质化竞争，方便做品牌定位、电商上架、外观专利保护，小成本就能做出专业产品质感，比 “跟风模仿” 更易打开市场。
7、合作需要提供什么资料？
基础资料即可：产品核心功能需求、目标人群、对手竞品、大致尺寸 / 材质偏好、预算范围、周期要求。
8、设计方案能修改几次？
合作初期明确修改规则：外观设计提供 3-5 版草图方案，定稿后支持 2-3 次细节修改；结构设计支持 1-2 次功能性调整，超出约定次数的重大修改会提前沟通，避免反复返工。
9、异地客户可以合作吗？
完全可以！目前异地客户占比超 60%，通过线上会议、文档协作、样品邮寄等方式沟通，进度实时同步，图纸和方案通过云端交付，不受地域限制，全国可服务。
10、会签订保密协议（NDA）吗？
必须签订！合作前可签订正式保密协议，明确产品创意、设计方案、图纸资料等核心信息的保密范围和期限，保障客户知识产权，杜绝信息泄露。
11、设计完成后能协助申请外观专利吗？
可以协助！提供申请外观专利所需的高清渲染图、六面视图、设计说明等资料，也可推荐长期合作的专利代理机构，降低申请门槛，保护设计成果不被抄袭。
12、付款方式是怎样的？
分阶段付款，降低双方风险：
① 合作启动付 40%-50% 预付款；
② 方案定稿后付 40%-50% 进度款；
③ 交付完整图纸后付剩余 0%-20% 尾款，支持公对公转账，可提供正规发票。
13、量产时发现设计问题，会负责调整吗？
会！在产品量产 1 年内，若因设计本身（非需求更新、工厂生产失误、硬件变更）导致的适配问题，免费提供图纸优化方案；超出质保期的，也可提供有偿技术支持，确保产品顺利落地。
14、可以只做外观设计，不做结构设计吗？
可以！支持单项服务定制，比如 “现有外观优化”、“根据已有结构重新设计外观”、“解决量产中的产品问题” 等，单独报价、单独签订服务合同，灵活适配不同需求。
Industrial Design Frequently Asked Questions
Below are the most commonly asked questions about industrial design from NINEIDEA Design clients, covering the entire cooperation process. For additional inquiries, please contact us directly for one-on-one consultation.
1. How do industrial design companies typically charge for their services?
Industrial design fees are determined by product category, design complexity, and whether the service includes structural design, 3D modeling, and mass production follow-up. We provide transparent quotations and customized solutions based on your product requirements with no hidden costs.
2. What is the general timeline for designing a product?
- Standard exterior design: 7-15 working days
- Full package (exterior + structural design): 20-40 working days
- Complex small home appliances or products with functional structures may require additional time. We provide real-time progress updates, accommodate necessary revisions, and guarantee no unnecessary delays throughout the process.
3. What is the difference between exterior design and structural design?
- Exterior design focuses on product styling, color schemes, tactile experience, and visual aesthetics, with the core objective of achieving “attractive appearance + comfortable grip”.
- Structural design manages internal component layout, snap-fit mechanisms, assembly processes, waterproofing, heat dissipation, and moldability for mass production, with the core objective of ensuring “functional usability + manufacturability”. Both are indispensable for a mature product.
4. Can you proceed with design if we only have a rough concept without a complete idea?
Absolutely. We support projects starting from vague concepts, hand-drawn sketches, or functional ideas. Our team conducts market and competitor analysis, transforms concepts into tangible designs, optimizes styling, and even provides multiple design options to build a comprehensive product solution from scratch.
5. Can you assist with connecting to manufacturers for mass production after design completion?
We offer one-stop production support! After design finalization, we provide complete engineering drawings, renderings, and structural blueprints. We can connect you with our long-term cooperative high-quality manufacturers, and oversee the entire process from mold opening, prototyping, to pre-production adjustments, avoiding the common industry pain point of “beautiful designs that cannot be mass-produced”.
6. Is custom industrial design suitable for startups?
Highly suitable. Differentiated design helps avoid homogeneous competition, facilitates brand positioning, e-commerce listing, and exterior design patent protection. Startups can achieve professional product quality with minimal investment, making it easier to penetrate the market compared to blindly following trends.
7. What information do we need to provide to start cooperation?
Basic information suffices:
- Core product functional requirements
- Target user demographics
- Competitor analysis
- Approximate size/material preferences
- Budget range
- Project timeline requirements
8. How many revisions are allowed for design proposals?
Revision rules are clearly defined at the beginning of cooperation:
- Exterior design: 3-5 sketch proposals provided initially, with 2-3 detail revisions allowed after finalization
- Structural design: 1-2 functional adjustments allowedMajor revisions exceeding the agreed number will be discussed in advance to avoid repeated rework.
9. Can clients from other regions cooperate with you?
Definitely! Over 60% of our current clients are from other regions. We communicate through online meetings, document collaboration tools, and sample delivery. Progress is updated in real-time, and design documents are delivered via cloud services, enabling us to provide nationwide service without geographical restrictions.
10. Will a Non-Disclosure Agreement (NDA) be signed?
Mandatory! A formal NDA can be signed before cooperation commences, clearly defining the scope and duration of confidentiality for core information including product concepts, design proposals, and technical drawings. This protects your intellectual property rights and prevents information leakage.
11. Can you assist with applying for exterior design patents after design completion?
Yes! We provide all necessary materials for patent applications, including high-resolution renderings, six-view drawings, and design descriptions. We can also recommend long-term cooperative patent agencies to lower application barriers and protect your design from infringement.
12. What is your payment method?
We adopt phased payments to reduce risks for both parties:
① 40%-50% advance payment upon project initiation
② 40%-50% progress payment after design proposal finalization
③ 0%-20% final payment upon delivery of complete design documents
We support corporate-to-corporate transfers and provide official invoices.
13. Will you be responsible for design adjustments if issues arise during mass production?
Yes! Within 1 year after mass production launch, we provide free drawing optimization solutions for adaptation issues caused by design flaws (excluding those resulting from requirement updates, manufacturer production errors, or hardware changes). For issues beyond the warranty period, we offer paid technical support to ensure smooth product launch.
14. Can we only request exterior design without structural design?
Certainly! We offer customized individual services, such as:
- “Optimization of existing exterior designs”
- “Redesign of exterior based on existing structures”
- “Resolution of product issues during mass production”Separate quotations and service contracts are provided for flexible adaptation to different needs.
