Waterproof Container Seal Groove for Serviceable Moisture Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers fail to maintain a watertight seal under varying environmental conditions, such as vibrations, and often require a permanent seal that makes servicing or maintenance of contents difficult, as traditional sealing methods can be compromised by pressure changes or deformation, leading to water penetration.
Innovation Solution
A waterproof container design featuring a base and lid with a channel and slot system, where a seal with a flared groove is used to create a reliable seal without requiring excessive pressure, allowing for easy assembly and maintenance while minimizing the risk of water intrusion, even when subjected to vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plastic laser welding is used to seal the container, then a permanent watertight seal is achieved, but the container cannot be opened for servicing contents
Solution Approach 1:
The sealing system is divided into separate, removable components: a lid portion with a seal and a base portion with a receptacle. This segmentation allows the lid to be detached from the base for servicing contents while the seal remains intact on the lid, enabling maintenance without compromising the sealing capability when reassembled.
Solution Approach 2:
The seal is designed as a recoverable component that remains attached to the lid when the lid is removed from the base. This allows the seal to be reused multiple times across different servicing cycles, maintaining its sealing function without being discarded or destroyed during the opening process.
2Reliability
If seal material is used to create a watertight connection, then moisture protection is achieved, but the container may warp providing water penetration points
Solution Approach 1:
The seal uses a flexible membrane or film structure that can accommodate thermal expansion and contraction of the container without causing warping. The flexible nature of the seal allows it to adapt to minor dimensional changes in the rigid container portions, maintaining the sealing function while preventing stress-induced deformation of the overall container structure.
