Problem
Portable electronic devices face protection challenges due to their sensitive nature, particularly in various environments, as existing solutions fail to provide comprehensive protection against water, dust, and physical damage while maintaining usability and interactivity.
Innovation Solution
A protective enclosure system comprising a flexible membrane and a rigid shell with a cushion layer, which tightly fits around the device to provide protection, includes openings for microphone and control access, and a stretchable cushion layer for added durability and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective cover is provided for the portable electronic device, then protection against water, dust, and physical damage is improved, but access to controls and functionality may be worsened
Solution Approach 1:
The protective cover is segmented into multiple functional layers: a rigid shell for structural protection, a flexible membrane for environmental sealing, and a cushion layer for shock absorption. Each layer is independently optimized to provide specific protection while allowing control access through precisely positioned openings.
Solution Approach 2:
The cover implements local quality by providing different types of protection in different areas: rigid protection for the shell, flexible sealing for the membrane, and cushioning for impacts. Additionally, openings are strategically positioned at specific locations to maintain control accessibility while preserving overall protection.
2Strength
If a rigid shell is used for protection, then physical impact resistance is improved, but flexibility and conformability to device shape may be worsened
Solution Approach 1:
The protective cover employs a composite structure combining a rigid shell made from hard plastic or polymer material with a flexible membrane layer. This composite design allows the rigid shell to provide impact resistance while the flexible membrane conforms to the device shape and provides environmental sealing.
3Object-affected harmful factors
If a flexible membrane is used for environmental protection, then water and dust sealing is improved, but structural rigidity and impact protection may be worsened
Solution Approach 1:
The protective cover utilizes a flexible membrane as a thin film layer that provides environmental protection by sealing against water and dust. This flexible membrane is positioned within the composite structure where it performs its sealing function without needing to provide structural rigidity, which is handled by the rigid shell.
4Reliability
If multiple layers are added for comprehensive protection, then protection effectiveness is improved, but device complexity and size may be worsened
Solution Approach 1:
The protective cover implements a nested structure where the flexible membrane is positioned inside or integrated with the rigid shell, and the cushion layer is embedded within the shell structure. This nesting approach allows multiple protective layers to be combined in a space-efficient manner, providing comprehensive protection while minimizing overall complexity and size increase.
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
The system effectively shields electronic devices from water, dust, and physical impacts while allowing easy access to controls and maintaining device functionality, offering a balance between protection and usability.
Implementation Method 1
The flexible membrane has elasticity such that it tightly fits the installed portable electronic device to protect the installed portable electronic device
Implementation Method 2
The stretchable cushion layer may be shaped, and have sufficient elasticity, to conform to an outer surface of at least the hard shell cover
