Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connection methods for devices in humid environments face challenges in achieving both waterproof and dustproof effects while being convenient and automatable, with traditional methods either compromising on installation complexity or effectiveness.
Innovation Solution
A quick-connection waterproof and dustproof joint comprising a rod part with gradient, constriction, and limit features, along with an elastic part, allows for seamless integration with a housing without side grooves or nuts, utilizing the elastic part's deformation to create a tight seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a slot connected to the through hole is set on the side of the housing for connector installation, then the installation convenience is improved, but the waterproof and dustproof effect deteriorates
Solution Approach 1:
The patent uses an elastic component (flexible element) that deforms during insertion to seal the through-hole from the interior side, creating a flexible seal that maintains waterproof and dustproof protection while allowing easy connector installation through the through-hole
2Object-affected harmful factors
If threaded fastening with nuts and bolts is used to install the connector, then the waterproof and dustproof effect is improved, but the manufacturing complexity and installation difficulty increase
Solution Approach 1:
The patent extracts and eliminates the need for nuts, bolts, and other fastening components by using a simple elastic sealing structure that provides both sealing and fixation functions, significantly simplifying the device structure and manufacturing process
Solution Approach 2:
The elastic component automatically seals and fixes the connector through its own elastic deformation when inserted, without requiring additional fastening operations or components, making the installation self-service and automation-friendly
3Object-affected harmful factors
If threaded fastening with nuts and bolts is used to install the connector, then the waterproof and dustproof effect is improved, but the installation time and labor requirement increase
Solution Approach 1:
The elastic component automatically seals and fixes the connector through its own elastic deformation when inserted, without requiring additional fastening operations or components, making the installation self-service and automation-friendly
Solution Approach 2:
The patent skips the time-consuming steps of threading, tightening, and fastening by using a single insertion motion that simultaneously achieves connector installation and sealing, dramatically reducing installation time
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a fast, convenient, and automated installation process with enhanced waterproof and dustproof performance, ensuring effective sealing without the need for additional fastening components.
Implementation Method 1
an elastic part movably sleeved on the rod part; after the rod part, the gradient part and the contraction part pass through the housing and then set outside the contraction part

AI summary
A quick-connection waterproof and dustproof joint and a quick-connection waterproof and dustproof connection structure, comprising a housing (9) and a quick-connection waterproof and dustproof joint. The housing (9) is provided with a through hole (91); the quick-connection waterproof and dustproof joint comprises a rod part (1); one end of the rod part (1) is provided with a gradient part (2), a contraction part (3) and a limit part (4); and the quick-connection waterproof and dustproof joint further comprises an elastic part (5) that is movably sleeved on the rod part (1). By providing the rod part (1), the gradient part (2), the contraction part (3), and the limit part (4), the connection between the quick-connection waterproof and dustproof joint and the housing (9) of an electric device does not need to be slotted on a side surface, and the waterproof and dustproof effects are good.
