Electrical Connector Waterproof Compartments for Durable Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors suffer from inadequate airtightness, allowing moisture and suspended particles to infiltrate, leading to corrosion, short circuits, and reduced lifespan due to reliance on imperfect waterproof pads or insufficient glue volumes.
Innovation Solution
A base with a connecting groove and retaining blocks forms waterproof compartments filled with glue, sealed by an upper lid, ensuring uniform pressure distribution and enhanced adhesion, using materials like Silicone or Epoxy for improved waterproofing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a waterproof pad is used to seal the electrical connector, then water resistance is improved, but the seal effectiveness deteriorates over time due to loss of elasticity and manufacturing tolerances
Solution Approach 1:
The patent changes the material parameter from elastic waterproof pad to rigid waterproof glue. The waterproof glue maintains its sealing properties over time without losing elasticity, as it cures to form a rigid barrier that does not degrade mechanically like elastic materials. This resolves the contradiction by maintaining reliable water resistance throughout the product lifecycle.
Solution Approach 2:
The patent uses a simple, inexpensive waterproof glue material that can be easily applied and cured. While the material itself is simple and short-lived in terms of application process, it creates a permanent seal that lasts the lifetime of the connector, eliminating the need for maintenance or replacement of sealing components.
2Manufacturing precision
If multiple waterproof compartments are created with waterproof glue, then airtightness is improved, but manufacturing complexity increases
Solution Approach 1:
The patent divides the internal space of the electrical connector into multiple separate waterproof compartments using retaining blocks. Each compartment is independently filled with waterproof glue, ensuring that if one compartment is compromised, others remain sealed. This segmentation approach improves overall airtightness and reliability while maintaining a relatively simple structure.
Solution Approach 2:
The patent applies waterproof glue specifically in critical areas where moisture infiltration would cause damage, rather than sealing the entire connector uniformly. The retaining blocks are strategically positioned to create compartments at key vulnerability points, providing localized protection where it is most needed while minimizing overall structural complexity.
