Waterproof Container Seal Groove for Vibration-Resistant Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container sealing technologies fail to maintain a watertight seal under varying environmental conditions, such as vibrations, and often require destructive access or compromise assembly ease and structural integrity.
Innovation Solution
A waterproof container design featuring a base and lid with a channel and slot system, utilizing a U-shaped seal with a flared groove that accepts an inner wall, allowing for secure sealing without deformation and easy assembly, using materials like injection molding or adhesives for securement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plastic laser welding is used to seal the container, then waterproof integrity is improved, but the container becomes destructive and cannot be accessed for servicing
Solution Approach 1:
The container is divided into separable components (base and lid) that can be joined and separated. The sealing interface is segmented into discrete sealing features (recesses, protrusions, gaskets) that allow for reversible assembly while maintaining waterproof integrity when closed.
2Reliability
If pressure is maintained between lid and container base to maintain seal, then waterproof integrity is improved, but the seal fails under vibration when pressure is reduced
Solution Approach 1:
The sealing features incorporate curved and contoured surfaces (recesses, protrusions, gasket profiles) that provide mechanical interlocking and distributed contact pressure. This geometric design maintains sealing force under vibration without requiring continuous high compression pressure.
3Reliability
If seal material is used to provide waterproof seal, then waterproof integrity is improved, but the container may warp providing water penetration points
Solution Approach 1:
A flexible gasket or seal member is used as the primary sealing element. This flexible component conforms to the sealing surface geometry and compensates for minor container warping or dimensional variations, maintaining waterproof integrity without requiring rigid seal-to-seal contact that could induce warping.
Solution Approach 2:
The sealing system combines multiple materials with complementary properties: the container base and lid use rigid materials for structural integrity, while the gasket uses a compliant material for sealing. This composite approach allows each material to perform its optimal function without causing warping.
4Ease of manufacture
If a simple seal design is used, then ease of manufacture is improved, but the seal may not provide adequate waterproof protection under varying conditions
Solution Approach 1:
The sealing system is segmented into discrete, pre-formed components (gasket, sealing protrusions, sealing recesses) that can be manufactured separately and assembled independently. This modular approach simplifies manufacturing while providing a robust multi-feature sealing system that maintains waterproof protection under varying conditions.
