Apple officially unveiled its highly anticipated first foldable screen phone, the iPhone Duo, at its special event themed "Bright New Chapter, Come Shine Bright." This new device innovatively applies artificial intelligence algorithms and 3D printing technology in the design and manufacturing of its hinge, aiming to address the durability challenges commonly faced by foldable screen phones. Apple's Chief Hardware Officer, Johnny Srouji, elaborated on the production process of this critical component.
Foldable screen phones, due to their unique structure, typically experience twice the wear and tear of traditional devices in daily use, which leads to many products showing significant degradation after a period of use. To tackle this industry-wide problem, Apple developed several innovative protective measures for the iPhone Duo's hinge. Srouji explained that during production, AI algorithms are used to precisely match each hinge with the most suitable housing, ensuring perfect alignment between the two. Subsequently, a confocal laser scans the surface morphology of the components step by step, followed by the use of 3D printing technology to create up to 25 layers of custom photosensitive polymer micro-layers, eliminating any residual surface undulations.
Beyond the core hinge technology, the iPhone Duo incorporates enhanced durability designs in other aspects as well. According to Srouji, the model features a "specially treated nano-textured surface that significantly reduces glare and reflections" and utilizes a multi-layer laminated structure to improve the overall durability of the device. More importantly, its multi-layer display structure slides relative to each other during opening and closing, a design that helps reduce screen deformation caused by repeated folding.
In terms of screen performance, Apple officially claims that the iPhone Duo's screen rigidity is 40% higher than other displays in the industry. Screen rigidity refers to the ability of the material or screen assembly to resist deformation; higher rigidity means the screen typically bends less and rebounds more stably when pressed, twisted, or folded. Additionally, the hinge itself adopts a custom variable torque design, complemented by magnets to assist in closing, further enhancing the smoothness of operation and the stability of the structure.
These technological innovations mark Apple's entry into the foldable screen market with the primary goal of addressing a core pain point in user experience—the long-term durability of the device. By combining advanced AI manufacturing processes with precise 3D printing technology, Apple aims to set a new industry standard for the structural reliability of foldable screen phones. This initiative not only concerns the market competitiveness of the iPhone Duo itself but also reflects the trend in consumer electronics towards deeper integration of intelligent design and advanced manufacturing.
Looking ahead, the hinge technology solution demonstrated by the iPhone Duo is likely to have a profound impact on the entire foldable screen device ecosystem. As more manufacturers launch similar products, balancing innovative form factors with lasting durability will become key. Apple's application of AI and 3D printing in the production of critical components provides a feasible reference path for future mass production of complex mechanical structures. Industry observers believe this could accelerate the popularization and iteration of related manufacturing technologies, driving foldable screen phones from a "novelty" stage to one of widespread "reliable durability."
