Waterproof Ring Flared Piece Eversion Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connector ports for two-in-one tablet laptop computers lack effective waterproof and dustproof designs, with non-waterproof designs failing to meet product requirements and vertically designed plastic members prone to distortion, compromising sealing integrity.
Innovation Solution
An electrical connector structure featuring a waterproof ring with a flared ring piece that deforms to fit the abutting surface, creating a seal and enhancing waterproof and dustproof effects, while maintaining structural stability through a design where the ring body's width is greater than the slope length of the flared ring piece.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a vertical plastic member design is added to achieve waterproof and dustproof effects, then sealing performance is improved, but the structure becomes prone to distortion and deformation during use
Solution Approach 1:
The waterproof ring employs a flexible deformable structure that dynamically adapts to the abutting surface. The ring body can elastically deform under pressing force to conform to the mating surface, creating an effective seal, and then recover its original shape when the force is removed. This dynamic behavior replaces the static rigid vertical plastic member design.
Solution Approach 2:
The invention changes the physical state and mechanical properties of the waterproof component from rigid to flexible. By using a deformable ring body with specific elastic properties, the structure can undergo controlled deformation to achieve sealing while maintaining overall structural stability through material property optimization.
2Device complexity
If no waterproof and dustproof design is used, then structural simplicity is maintained, but waterproof and dustproof requirements are not met
Solution Approach 1:
The invention uses a flexible ring body as the waterproof component, which is much simpler than traditional rigid waterproof structures. The thin-walled deformable ring can be easily integrated into the connector assembly while providing effective sealing through its ability to conform to the abutting surface under compression.
3Object-affected harmful factors
If the flared ring piece deforms in an everted manner to fit the abutting surface, then sealing performance is enhanced, but the ring body may dislocate from the ring groove
Solution Approach 1:
The invention employs a counterbalancing geometric design where the ring body width is made greater than the slope length of the flared ring piece. This creates a stabilizing effect where the broader base of the ring body counteracts the dislocating force generated during eversion deformation, keeping the ring securely positioned in the groove while maintaining sealing effectiveness.

Function Achieved in This Case
The solution effectively prevents moisture and dirt from entering the connector, enhancing waterproof and dustproof performance and maintaining structural stability by ensuring the ring body remains securely positioned during deformation.
Implementation Method 1
the abutting surface presses against the flared ring piece such that the flared ring piece is deformed in an everted manner and is molded to fit the abutting surface
