Metallic Device Case with Fluorinated Rubber Shock Absorbers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional device cases with metallic exteriors risk damage due to metal-to-metal contact, leading to potential damage when subjected to external shocks.
Innovation Solution
A device case design featuring a metallic case body with a bezel as the first exterior and a guard member as the second exterior, both made of metallic materials, with buffers made of fluorinated rubber disposed between them to absorb shocks and prevent direct contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If metallic exteriors (bezel and guard member) are used to achieve a luxurious appearance, then aesthetic quality is improved, but the risk of damage due to metal-to-metal contact increases
Solution Approach 1:
A buffer member made of fluorinated rubber is introduced as an intermediary between the metallic bezel and guard member. This buffer absorbs external shocks and prevents direct metal-to-metal contact, thereby maintaining the luxurious metallic appearance while eliminating the damage risk associated with metal contact.
Solution Approach 2:
The device case combines different materials - metallic materials for the bezel and guard member to achieve luxurious appearance, and fluorinated rubber for the buffer to provide shock absorption. This composite material approach allows simultaneous achievement of aesthetic quality and damage resistance.
2Reliability
If buffers are disposed between metallic exteriors to prevent damage, then reliability is improved, but device complexity increases
Solution Approach 1:
The buffer is formed as a thin-walled hollow spherical structure made of fluorinated rubber. This flexible shell design provides effective shock absorption while maintaining a compact form factor that does not significantly increase the overall device complexity.
Solution Approach 2:
The hollow spherical buffer is disposed within the space between the bezel and guard member, effectively nesting the shock-absorbing element within the existing structural boundaries. This nesting approach allows the buffer to be integrated without substantially increasing external dimensions or structural complexity.

AI summary
Disclosed is a device case including: a first exterior that is placed on an upper surface side of a case body; a second exterior that covers at least an upper portion of the first exterior; and a first position buffer as a buffer disposed between the first exterior and the second exterior. The first exterior includes an inclined surface on an upper surface side, and the first position buffer is disposed on the inclined surface of the first exterior.
