Innovation Solution
A protective case with hinges or folds, elastic securing members, and rigid support structures that allow for multiple configurations, including 'closed book', 'open book', 'folded open', and 'propped open' positions, enabling secure storage and display of various electronic devices at desired angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a protective case is designed to fit only a single electronic device, then the device is well protected, but the case cannot accommodate a variety of devices of different sizes and shapes
Solution Approach 1:
The case is divided into a body portion and a cover portion that can move relative to each other through hinges or folds. The cover portion can be positioned in multiple configurations (closed, open, propped open at various angles), allowing the case to adapt to different device sizes while maintaining protection through the body portion's retaining features
Solution Approach 2:
The case incorporates dynamic elements including hinges or folds that allow the cover portion to move between multiple positions, and elastic members that can flex to accommodate different device dimensions. This dynamic structure enables the case to adapt to various devices while maintaining secure retention through adjustable configurations
2Adaptability or versatility
If a protective case is made simple in structure, then it is easy to manufacture, but it cannot provide multiple viewing orientations
Solution Approach 1:
The case is segmented into movable cover portion and stationary body portion connected by hinges or folds, enabling multiple viewing orientations without requiring complex mechanical assemblies. Each hinge or fold acts as an independent segment that can be positioned to create desired viewing angles
Solution Approach 2:
The elastic members automatically bias the cover portion toward the closed position, providing self-closing functionality. The hinges or folds naturally maintain the cover portion in various viewing orientations without requiring additional locking mechanisms, reducing overall structural complexity while maintaining versatility
3Adaptability or versatility
If elastic members are used to secure devices, then the case can accommodate various device sizes, but the elastic members may deform under heavy devices
Solution Approach 1:
The retention system is segmented into multiple independent retaining features distributed around the body portion (such as hooks, loops, and elastic members positioned at different locations). This segmentation allows the weight of heavy devices to be distributed across multiple attachment points rather than concentrated on single elastic members, preventing deformation while maintaining adaptability
Solution Approach 2:
The case combines multiple retention mechanisms (hooks, loops, elastic members, and rigid support structures) working together to secure devices. This merged system provides both the adaptability to accommodate various device sizes and the cumulative strength needed to support heavy devices without deformation
