Solution Overview
Problem
Current methods for protecting 3D cover glass in handheld electronic devices are inadequate in preventing sharp contact failure, as they primarily focus on flat glass solutions.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional flat glass protection methods are used, then manufacturing simplicity is maintained, but protection effectiveness against sharp contact failure is insufficient
Solution Approach 1:
The glass protection system is divided into multiple segments: a glass sleeve, end caps, a frame, and a shock-absorbing interlayer. This segmentation allows each component to perform its specific function optimally, with the interlayer providing shock absorption and the frame providing structural support, thereby improving overall protection effectiveness while managing complexity through modular design
Solution Approach 2:
The invention uses composite material structures combining glass with polymer interlayers and frame materials. The glass sleeve is combined with a shock-absorbing interlayer and a frame structure, creating a composite protection system that leverages the strength of glass while compensating for its brittleness through the flexible interlayer and supportive frame
2Strength
If glass thickness is increased to improve strength, then resistance to sharp contact failure improves, but device weight and size increase
Solution Approach 1:
A shock-absorbing interlayer is introduced as an intermediary between the glass sleeve and the frame. This interlayer absorbs impact forces and distributes them across the frame structure, allowing the use of thinner, lighter glass while maintaining protection effectiveness. The interlayer acts as a mediator that compensates for reduced glass thickness
Solution Approach 2:
The invention changes the protective approach from relying solely on glass thickness parameters to using a composite structure with controlled thickness parameters. By introducing the interlayer and frame, the system achieves equivalent or superior protection with reduced glass thickness, thereby reducing overall weight
3Adaptability or versatility
If complex 3D glass structures are used, then design versatility improves, but susceptibility to sharp contact failure increases
Solution Approach 1:
The shock-absorbing interlayer is positioned beforehand between the glass sleeve and the frame to cushion against potential impact forces. This prior cushioning arrangement protects the 3D glass structure from sharp contact failures before they can occur, allowing complex 3D designs to be used without increasing vulnerability
Solution Approach 2:
The invention converts the potential harm of impact forces into beneficial distributed stresses through the interlayer and frame structure. When impact occurs, the interlayer absorbs and distributes the force, converting the concentrated harmful sharp contact into distributed beneficial stresses that the 3D glass structure can better withstand

Function Achieved in This Case
The solution effectively reduces the risk of sharp contact failure and damage to the glass sleeve by distributing impact forces and providing shock absorption, enhancing the durability of 3D cover glass in portable electronic devices.

AI summary
A glass sleeve assembly for a portable electronic device may comprise a glass sleeve extending longitudinally from a first opening defined by a first rim to a second opening defined by a second rim. The glass sleeve may have an internal surface. A first end cap may be positioned adjacent to the first opening and may have at least a portion extending longitudinally beyond the first rim. A second end cap may be positioned adjacent to the second opening and may have at least a portion extending longitudinally beyond the second rim. A frame may comprise first and second ends and a central portion between the first and second ends. The central portion may be located within the glass sleeve. The ends of the frame may be connected to the end caps. Shock absorbing interlayers may be mounted to the end caps and the glass sleeve.
