Personal Electronic Device Case with Layered Protection and Adjustable Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing travel cases for electronic devices, particularly head-mounted displays, are rigid and inflexible, offering inadequate protection and adjustability for devices of varying sizes, leading to discomfort and limited versatility.
Innovation Solution
A case design featuring hingedly connected shells with a layered structure comprising a rigid inner layer, foam layer, batting, and flexible outer jacket, allowing for adjustable storage and secure holding of different-sized devices, along with a retractable handle and slider mechanism for customizable fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid materials such as polymers are used for the travel case, then protection strength is improved, but comfort and adjustability deteriorate
Solution Approach 1:
The case is divided into multiple functional layers: a rigid inner shell for structural protection, a foam layer for cushioning, and a flexible outer jacket for comfort. Each layer performs a specific function, resolving the contradiction between strength and comfort through functional segmentation.
Solution Approach 2:
The case employs a composite structure combining rigid polymer materials (for strength), foam materials (for cushioning), and flexible fabric materials (for comfort). This multi-material composite approach allows simultaneous achievement of protection strength and user comfort that cannot be achieved with a single material.
2Stability of the object's composition
If rigid materials are used for the travel case, then structural stability is improved, but adaptability to different device sizes deteriorates
Solution Approach 1:
The case incorporates adjustable elements including a movable divider that can be repositioned to accommodate devices of different sizes, and a flexible outer jacket that can adapt its shape. This dynamic adjustability maintains structural stability while providing versatility for different device dimensions.
Solution Approach 2:
Different regions of the case have different properties: the rigid inner shell provides structural stability, while the flexible outer jacket provides adaptability. The movable divider allows local adjustment in the storage compartment to fit various device sizes without compromising overall structural integrity.
3Strength
If a layered structure with multiple materials is used, then protection and comfort are improved, but device complexity increases
Solution Approach 1:
The case is segmented into distinct layers (rigid shell, foam layer, flexible jacket) where each layer has a specific function. This segmentation simplifies the design process and material selection for each component while achieving comprehensive protection and comfort, rather than attempting to create a single complex multi-functional material.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Provides enhanced protection, adjustability, and comfort during transport by accommodating various device sizes and shapes, while maintaining security and ease of use.
Implementation Method 1
The rigid layer may maintain a fixed shape during handling by a user
Implementation Method 2
The batting may be compressible and the outer jacket may be flexible, such that the outermost surface of each shell may not maintain a fixed shape during handling by a user
Implementation Method 3
provides cushioning characteristics during travel
Implementation Method 4
The case may include a first shell and a second shell hingedly connected at edges thereof. The case may be configured to be opened and closed by rotating the first shell and the second shell relative to each other about their hinged connection

AI summary
A case for storing and carrying a personal electronic device may include a first shell and a second shell each including a rigid layer, a foam layer, batting, and an outer jacket. The rigid layer may have a concave inner surface and a convex outer surface, the foam layer may cover the outer surface of the rigid layer, the batting may cover the foam layer, and the outer jacket may cover the batting. The first shell and the second shell may be hingedly connected at edges thereof so as to be opened and closed. When closed together, the first shell and the second shell may form an interior cavity of the case.
