Foldable iPhone and iPad to Feature Ultra-Thin Glass: Analyst

Apple is expected to release foldable iPhone and iPad devices in the next couple of years. Analyst believes these devices will have ultra-thin glass. Apple is collaborating with Corning to achieve this. Ultra-thin glass will provide a seamless and durable user experience for the foldable devices.

Apple Inc. has recently been granted a U.S. Patent for a novel haptic engine design that significantly enhances the shock resistance of electronic devices [1]. This innovation, which focuses on protecting internal components from damage caused by impact events such as drops or collisions, is a significant step forward in hardware resilience and user-centric engineering.

The patent introduces a mechanical system that incorporates non-linear spring assemblies, specifically cantilevered leaf springs, which absorb and redistribute impact forces. These springs are strategically positioned within the lid of the haptic engine, and their geometry—including chamfered edges and variable thickness—creates a non-linear stiffness profile. This design allows the springs to respond gently to minor impacts but stiffen under heavier loads, effectively cushioning the engine’s suspended mass.

The haptic engine includes a moveable mass suspended by flexures inside an enclosure. During normal operation, the mass vibrates to produce tactile feedback. In the event of a drop or collision, the mass may shift violently. Instead of striking the enclosure directly, the mass contacts the cantilevered springs, which absorb and dissipate the energy. The springs’ design ensures that force is distributed over time, minimizing the risk of component failure.

The patent outlines use cases for a wide range of Apple products, including smartphones, smartwatches, and wearables. By integrating this shock-resistant system, Apple aims to improve the longevity, reliability, and user experience of its devices without increasing their size or weight.

This innovation reflects Apple’s ongoing commitment to hardware resilience and user-centric engineering. As haptic feedback becomes more integral to immersive experiences, especially in spatial computing and wearable tech, ensuring that these systems can withstand real-world conditions is critical.

The patent also opens the door to modular haptic designs, where spring assemblies could be tuned or replaced based on device type or user preference. This flexibility could lead to more customized and durable products.

In addition to this patent, Apple is also expected to release foldable iPhone and iPad devices in the next couple of years. Analysts believe these devices will feature ultra-thin glass, provided by Corning, to ensure a seamless and durable user experience [2].
