고객 및 시장의 문제점

Customers and market participants face several pain points in the rear seat ventilation switch supply chain. Quality inconsistency is a major issue, with some Chinese manufacturers delivering switches that fail early due to poor solder joints or substandard plastic materials. Long lead times for custom tooling (4–6 weeks) can delay product launches. Communication barriers, including language and time zone differences, often lead to specification misunderstandings. Intellectual property theft remains a concern, with some factories copying designs without authorization. Logistics challenges, such as port congestion and shipping delays, disrupt just-in-time manufacturing. Additionally, fluctuating raw material prices for copper and plastics impact cost predictability. Finally, the lack of standardized testing protocols across suppliers makes it difficult to compare product quality objectively. Addressing these pain points requires rigorous supplier vetting, clear contracts, and ongoing quality audits.
