Screwless Faucet Trim Sealing Structure for Fast Waterproof Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional embedded faucet trims require screws for fixation, compromising water-proof ability and appearance, and slow down installation.
Innovation Solution
A faucet trim design featuring a cover with a flange and a seal, where the flange and seal engage in a groove, allowing screw-less installation and enhanced water-retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If screws are used to fix the faucet trim, then the faucet trim can be stably fixed, but the water-proof ability is reduced and the appearance is affected
Solution Approach 1:
The invention extracts and eliminates the screws (fastening members) from the faucet trim structure. Instead of using screws to fasten the cover to the base, the patent uses an integrated elastic base that directly engages with the faucet body through elastic deformation, completely removing the need for separate fastening components that would compromise water-proofing and appearance.
Solution Approach 2:
The invention employs an elastic base made of flexible material that can deform elastically to engage with the faucet body. This flexible base replaces the rigid screw-fastening system, allowing the cover to be securely attached while maintaining water-proof integrity and aesthetic appearance without visible fastening holes.
2Stability of the object's composition
If screws are used to fix the faucet trim, then the faucet trim can be stably fixed, but the installation speed is reduced
Solution Approach 1:
The invention removes the multi-step screw fastening process entirely. The elastic base design allows for tool-free, rapid installation by simply pressing the cover onto the faucet body, eliminating the time-consuming operations of aligning holes, inserting screws, and tightening fasteners.
Solution Approach 2:
The elastic base performs self-fastening through its elastic properties. When the cover is placed on the faucet body, the elastic base automatically deforms and engages with the faucet, creating a secure connection without requiring external fastening tools or additional components, thereby dramatically speeding up installation.
3Ease of operation
If holes are provided in the faucet trim for screw installation, then the faucet trim can be fixed, but the appearance is affected and water-proof ability is reduced
Solution Approach 1:
The invention eliminates the need for installation holes by removing the screw fastening system entirely. The elastic base engages with the faucet body through surface contact and elastic deformation, allowing the cover to be securely fixed without any holes that would compromise appearance or water-proofing.
Solution Approach 2:
The elastic base uses flexible material properties to achieve secure attachment without penetrating holes. The material deforms elastically to create friction and mechanical engagement with the faucet body, maintaining the integrity and appearance of the faucet trim while enabling reliable installation.

AI summary
A faucet trim is provided, wherein the faucet trim includes: a cover including a main body, a flange and a through hole, the flange projecting obliquely from a periphery of the through hole and being protrusive from the main body, the flange and the main body defining a receiving space therebetween; and a seal including a base and a projection projecting from the base, the projection and the base defining a groove in which the flange is engaged; wherein in the axial direction of the through hole, the base is not protrusive beyond the receiving space, the projection is located outside the receiving space, and the projection is partially overlapped with the through hole.
