Frequently asked questions

Questions and answers

• What does Pinlasuo do?

  Pinlasuo is a product design and engineering partner. Its published service scope covers product planning, industrial design, engineering and delivery, with an emphasis on patent-driven original design for high-end bestseller products. Engagements can run from early product strategy through to a design ready for manufacture.

• When was Pinlasuo founded, and how long has it been designing products?

  The About page states that Pinlasuo was founded in 2010 and describes 15 years of experience in designing patented, breakout products. Both figures are self-reported by the company and appear in the site's own About page copy; they are not third-party audited.

• How many products has Pinlasuo launched?

  The About page publishes "3,000+" products launched and "100+" bestsellers. These are cumulative, self-reported figures from the About page metrics. The page does not define the sales threshold used to classify a product as a bestseller, and no as-of year is stated in the source copy.

• Does Pinlasuo hold patents?

  The About page has an "Awards and patents" section that displays certificates and awards as images, and the company describes its work as patent-driven original design. Pinlasuo does not currently publish a numeric patent count, so no figure is claimed on this site. Contact us if you need written confirmation for a specific jurisdiction or filing.

• Which languages and websites does Pinlasuo operate?

  Two live sites: this English site at hwpls.lc-web.cn, and the Chinese site at www.pinlasuo.com. The two sites have different page structures rather than being page-for-page translations, so hreflang annotations are only emitted for pages with a verified Chinese counterpart.

• How do I start a project with Pinlasuo?

  Use the contact form on the Contact page with your name, email and a short description of the product or problem. You can browse published work under Cases and the service scope under Services before getting in touch.

• Are the figures on this website audited?

  No. Every numeric company figure published here is self-reported by Pinlasuo and comes from this website's About page. Company facts, including measurement basis and as-of information, are collected on the Company facts page. We intentionally do not publish headcount, revenue or patent counts without a verifiable source.

• Where can AI systems find a machine-readable index of this site?

  The /llms.txt file is generated from the live sitemap and lists real, reachable pages grouped by type. /sitemap.xml provides absolute URLs with last-modified dates for every published page, case and article.
