事实上，这是一款很不寻常的设备，并主要体现在两个方面。其一，是moto选择了CES、而非手机厂商更 习惯的MWC来首发。其二，就在于moto仅仅只公布了新品的外观，至于硬件配置、细节参数则是一点也 没透露。 不过得益于神通广大的网友，我们还是得知了Razr Fold真正的"特别之处"。简单来说，它可能是智能手机 行业有史以来第一款"廉价大折叠"。据称，这款机型将不会采用顶级的至尊版骁龙平台，并且定价也要显 著低于其他的"大折叠"竞争对手。 主要原因可能有三点。首先是2025年，在全球手机市场整体出货量下滑的背景下，折叠屏依然取得了6%的 增长，但这一增长速度已然比两年前缩水了超过60%。 近日，moto在CES 2026期间主动披露了他们的首款"大折叠"Razr Fold。 可能有的朋友会说，之前OPPO的Find N、Find N2，还有荣耀的Magic V Purse，不也都算是"廉价大折 叠"吗，moto这个怎么就特别了？ 请注意，OPPO的前两代Find N严格来说其实并不算"大折叠"。同时，它们与荣耀Magic V Purse也都没有采 用当时最新世代的SoC，因此本身从产品定位上就与公众认知中的" ...

Core Viewpoint - The article discusses the evolution and significance of hinge technology in foldable smartphones, highlighting the different types of hinges, their advantages and disadvantages, and the impact of material innovations on performance and cost [2][5][6]. Industry Perspective - Foldable hinge technology has undergone multiple iterations since the first commercial foldable phone was launched in 2019, leading to various technical routes and design philosophies [2]. - The main types of hinge technology include U-shaped hinges, waterdrop hinges, and other types, each with unique characteristics affecting crease control, thickness, cost, and durability [2]. U-Shaped Hinge - The U-shaped hinge, exemplified by the Samsung Galaxy Fold series, is a simpler and cost-effective design but suffers from significant drawbacks such as visible creases and potential screen damage over time [3]. - This hinge design has been criticized for allowing dust ingress and causing aesthetic issues due to gaps when closed [3]. Waterdrop Hinge - The waterdrop hinge, commonly used by domestic manufacturers like OPPO and Huawei, allows for a larger bending radius, reducing screen creases and providing a seamless closure [4]. - While offering advantages such as shallower creases and improved user experience, the complexity of the waterdrop hinge increases production costs and device thickness [4]. Evolution of Hinge Technology - The evolution of hinge technology reflects the transition of foldable smartphones from being merely functional to providing a better user experience, with advancements in materials and structural design [5]. - The latest innovation is Huawei's "Tiangong Hinge System," which supports both inward and outward folding, marking a new stage in hinge technology development [5]. Material Innovations - The performance of foldable hinges is closely tied to material selection, with advancements from traditional stainless steel to revolutionary liquid metal materials enhancing strength and fatigue resistance [6]. - Metal Injection Molding (MIM) is the mainstream choice for hinge manufacturing, while liquid metal offers superior properties, making it ideal for components requiring repeated folding [6]. Market Dynamics - The global foldable hinge market is projected to exceed $900 million in 2024, with a growth rate of nearly 5% [7]. - The introduction of tri-fold smartphones increases the number of required hinges, suggesting further market expansion [7]. - The market is characterized by high technical barriers, dense patent layouts, and a trend towards consolidation among leading companies [7]. Regional Distribution - Hinge manufacturers are primarily located in China and South Korea, with the U.S. excelling in design but less involved in manufacturing [8]. - Chinese companies are increasingly competitive across the entire supply chain, from materials to design and manufacturing [8]. Cost Structure - Hinges represent a significant incremental cost in foldable smartphones, with individual costs ranging from 800 to 1200 yuan, influenced by material choices and manufacturing complexity [8]. - Reducing hinge costs is crucial for the broader adoption of foldable smartphones, with potential improvements through material substitution and process enhancements [8]. Challenges in the Industry - The industry faces challenges such as reliance on foreign high-end materials and increasing competition, necessitating ongoing R&D investment [9]. - However, advancements in MIM technology and liquid metal by Chinese firms are enhancing the self-sufficiency of the supply chain [9]. Market Forecast - The global foldable hinge module market is expected to reach $1.82 billion by 2031, with a compound annual growth rate (CAGR) of 6.8% [10].
