Waterproof Mobile Case Curved Gasket Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices are not compatible with water and cannot be used in wet environments or underwater due to lack of protection from dust, debris, and liquids, limiting their usage in various activities.
Innovation Solution
A mobile device case with a body portion and a bottom portion featuring a sealing gasket and connection arrangement, including a clasp or hinge, that forms a watertight seal, allowing the device to be used in wet conditions up to a depth of 30 meters while protecting it from harsh elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mobile devices are used in wet environments or underwater, then the device can be used in more activities and locations, but the device is damaged by water, dust, and debris
Solution Approach 1:
A protective case with sealing gaskets acts as an intermediary barrier between the mobile device and the wet environment. The gasket creates a sealed interface between the case body and bottom portion, preventing water and debris from reaching the device while allowing the device to function in previously incompatible environments.
Solution Approach 2:
The sealing gasket is made from a flexible material that can deform to accommodate the interface between rigid case components. This flexible element conformally seals the joint between the case body and bottom portion, maintaining the waterproof barrier even when subjected to pressure changes during submersion.
2Reliability
If a protective case with sealing gasket is used, then the device is protected from water and debris, but the case complexity increases with additional components
Solution Approach 1:
The sealing gasket is integrated directly into the case structure, merging the protective function with the case components themselves. The gasket is positioned to engage with both the case body and bottom portion, creating a unified sealing system that protects the device without requiring separate protective elements.
Solution Approach 2:
The case structure serves multiple functions simultaneously: the body and bottom portion provide physical protection, while the integrated gasket provides waterproof sealing. The clasp mechanism both secures the case closed and maintains the seal integrity, combining structural and protective functions in a single system.
3Reliability
If a clasp locking arrangement is used to secure the case, then the seal remains intact under water pressure, but the ease of operation decreases due to additional locking steps
Solution Approach 1:
The gasket is pre-positioned in a compressed state between the case body and bottom portion when the case is closed. This preliminary compression creates the seal before water pressure is applied, allowing the seal to resist pressure without requiring additional active mechanisms during use.
Solution Approach 2:
The clasp mechanism transitions between locked and unlocked states dynamically. When closed, the clasp maintains continuous pressure on the gasket to ensure seal integrity under water pressure. When opened, the clasp releases to allow easy access, with the gasket returning to its neutral state.

AI summary
A mobile device case is disclosed. The mobile device case includes a body portion and a bottom portion. One portion includes a gasket configured to sealingly contact both the body portion and the bottom portion. The body portion and the bottom portion include mating curved surfaces. The gasket is a curved gasket that mates with the curved surfaces of the body portion and the bottom portion. The body portion and the bottom portion include a connection arrangement configured to releasably connect the body portion to the bottom portion. The connecting arrangement includes at least a first locking arrangement disposed in part on the first side of the body portion and the first side of the bottom portion.
