Ring-Shaped Cover for Portable Devices Using Segmented Materials
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional protective covers for portable electronic devices often impede usage while providing inadequate protection against scratches, dents, and other forms of damage.
Innovation Solution
A protective outer cover formed from different materials, such as stiff plastic and compliant elastomer, using injection molding techniques, which provides side and edge protection without hindering access to essential components like connectors and buttons, and allows for easy attachment and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional protective covers are used, then protection against scratches and dents is improved, but ease of operation deteriorates due to impeded access to components
Solution Approach 1:
The protective cover is divided into multiple functional zones: rigid portions for protection, flexible portions for compliance, and openings for component access. This segmentation allows each zone to perform its specific function independently while contributing to the overall protective yet accessible cover design.
Solution Approach 2:
Different portions of the cover have different material properties tailored to their specific functions: rigid plastic portions provide structural protection, flexible elastomer portions provide compliance and secure attachment, and opening portions provide access to components. This local differentiation of material qualities resolves the contradiction between protection and accessibility.
2Object-affected harmful factors
If rigid protective material is used, then protection capability is improved, but adaptability to device contours deteriorates
Solution Approach 1:
The cover employs different material properties in different locations: rigid material where structural protection is needed and flexible material where compliance with device contours is needed. This local differentiation allows the cover to simultaneously achieve both protection capability and adaptability to the device shape.
Solution Approach 2:
The cover is constructed as a composite structure combining rigid plastic material and flexible elastomer material. This composite construction allows the cover to exhibit both rigid protective characteristics and flexible adaptive characteristics, resolving the contradiction between protection capability and contour adaptability.
3Reliability
If secure attachment is achieved, then reliability of protection is improved, but ease of operation deteriorates due to difficulty in removal
Solution Approach 1:
The flexible portions of the cover enable dynamic attachment and removal: during attachment, the flexible material expands to envelop the device securely; during removal, the flexible material can be deliberately expanded to release the grip. This dynamic behavior resolves the contradiction between secure attachment and ease of removal.
Solution Approach 2:
The attachment state of the cover is controlled by changing the physical parameters of the flexible material, specifically its expansion and contraction. By deliberately changing these parameters, the user can transition between secure attachment and easy removal states, resolving the contradiction between reliability and ease of operation.
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 solution effectively reduces damage to portable electronic devices by providing robust side and edge protection while maintaining full functionality and ease of use, making it suitable for handheld devices.
Implementation Method 1
The outer cover can include an elastomer section that facilitates slight expansion of the outer cover. The slight expansion facilitates attachment and removal of the outer cover to an electronic device, while still being able to be securely attached to the electronic device when acting as an outer cover therefor.
Data Source
AI summary
An outer cover for an electronic device, such as a portable electronic device, is disclosed. Since portable electronic devices are often portable, they can be damaged, such as scratched, dented, broken, and the like, when transported or used. The outer cover can serve to provide a protective member over part of the housing for the electronic device. The protective member, when placed on the portable electronic device can serve to reduce damage to sides of the portable electronic device. While the outer cover can provide side and/or edge protection, the outer cover need not also provide front or rear protection.
