Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waterproof devices for connector joints require multiple components, increasing costs and complicating the assembly process, and necessitate on-site cable and connector connection, which hinders productivity.
Innovation Solution
A waterproof device with a simple structure featuring a body portion with a connection groove for the modular jack and an elastic member with a connector inserting hole, allowing for pre-connection of cables and connectors, and integral formation of the body and elastic member for ease of installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple components are used in the waterproof device, then the sealing reliability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent merges multiple separate components (back cover, cable waterproofing gasket, connector protective cover) into a single integrated waterproof device. The body portion incorporates the housing structure while the elastic member provides the sealing function, eliminating the need for multiple discrete parts and simplifying the overall device complexity while maintaining sealing reliability.
Solution Approach 2:
The elastic member serves multiple functions simultaneously: it acts as a seal to prevent moisture ingress, provides a mechanical barrier for cable insertion, and enables waterproofing through its deformation capability. This multi-functionality reduces the need for separate specialized components.
2Reliability
If multiple components are used in the waterproof device, then the sealing reliability is improved, but the assembly process becomes complicated and productivity decreases
Solution Approach 1:
By integrating the back cover, cable waterproofing gasket, and connector protective cover into a single waterproof device with a body portion and elastic member, the assembly process is simplified from multiple separate assembly steps to a single installation operation, significantly improving productivity.
Solution Approach 2:
The waterproof device is segmented into two main functional parts: the body portion (housing) and the elastic member (sealing component). This segmentation allows for simple assembly where the elastic member is installed within the body portion, maintaining ease of assembly while ensuring reliable sealing.
3Reliability
If the cable is connected to the connector after insertion into all waterproof device components, then the waterproofing is ensured, but the installation process becomes complex and requires on-site connection
Solution Approach 1:
The elastic member is pre-installed within the body portion during manufacturing, creating a pre-configured waterproof assembly. This allows the cable and connector to be connected in advance before final installation, as the waterproofing mechanism is already in place and will automatically seal around the cable regardless of when the connection is made.
Solution Approach 2:
The elastic member automatically adapts to seal around the cable through its inherent elasticity and deformation capability. When the cable is inserted through the connector inserting hole, the elastic member deforms to conform to the cable shape and size, creating a waterproof seal without requiring additional adjustment or intervention, thus enabling ease of installation while maintaining waterproofing.

AI summary
Disclosed is a waterproof device for a connector joint. The waterproof device, which seals a joint of a modular jack and a connector to waterproof the joint, includes: a body portion having a hollow inner portion, and a connection groove which is formed on an inner circumference of one end of the body portion, and is shaped corresponding to the modular jack so that the modular jack is coupled and fixed to the body portion; and an elastic member formed to surround an outer circumference of the body portion and to have an insertion portion having a connector inserting hole which is formed on a side opposite to a side where the modular jack is coupled, and through which the connector passes, wherein after the connector passes therethrough, the cable of the connector is pressed against the connector inserting hole to seal an inside of the body portion.
