Curved Bath Curtain Rack Pivot Structure for Easy Wall Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bath curtain rack assembly requires precise alignment and adjustment, making it inconvenient and prone to loosening, as the base and pivot rod must be securely attached to the wall in a specific order.
Innovation Solution
A bath curtain rack structure featuring a curved transverse rod connected to pivot members with hollow pipe sections and wall-mounted brackets, utilizing headless screws and dual awl-shaped guide holes for easy assembly and adjustment, with stoppers to prevent over-rotation and secure attachment to the wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional assembly methods with screws extending through adjustment mechanisms are used, then the bath curtain rack can be secured to the wall, but the assembly requires precise alignment and adjustment which makes it inconvenient and time-consuming
Solution Approach 1:
The invention divides the assembly into modular components: wall-mounted brackets with protruding posts, pivot members with guide holes, and transverse rods. This segmentation allows each component to be independently positioned and connected, eliminating the need for complex pre-alignment while maintaining secure attachment through the guide hole-post fitment mechanism.
Solution Approach 2:
The dual awl-shaped guide holes act as intermediaries between the protruding posts and the transverse rods. These guide holes facilitate easy insertion and positioning by providing a tapered path that naturally aligns components during assembly, while the concave pivot points serve as intermediaries to limit rotation and secure the connection without requiring precise pre-adjustment.
2Reliability
If precise alignment and adjustment are performed during assembly, then the bath curtain rack can be securely attached, but the assembly may be loosened easily over time
Solution Approach 1:
The invention incorporates preliminary anti-loosening measures through the guide hole design. The dual awl-shaped guide holes with concave pivot points create a mechanical interlock that prevents backward movement and loosening. The stoppers that engage with the semi-circle flanges also provide preliminary anti-action by limiting rotation range and preventing over-tightening or loosening during use.
Solution Approach 2:
The protruding posts are pre-positioned on the wall-mounted brackets, and the guide holes are pre-formed with concave pivot points. This preliminary positioning eliminates the need for complex alignment during assembly and ensures that components fit together in the correct orientation, preventing future loosening by maintaining proper geometric relationships.
3Reliability
If complex adjustment mechanisms are used to secure the base and pivot rod, then the attachment can be secure, but the assembly process becomes inconvenient and difficult to operate
Solution Approach 1:
The invention extracts the complex adjustment mechanism from the assembly process. Instead of using screws extending through adjustment mechanisms, the design uses simple protruding posts that fit into guide holes with concave pivot points. This extraction eliminates the need for complex adjustment operations while maintaining secure attachment through the geometric fit of the guide hole-post connection.
Solution Approach 2:
Instead of having screws extend through adjustment mechanisms to secure components, the invention inverts the approach by having protruding posts on the wall-mounted brackets fit into guide holes on the pivot members. This inversion simplifies the assembly process by eliminating the need for adjustment mechanisms while maintaining secure attachment through the reversed connection geometry.

AI summary
A bath curtain rack structure includes a curved transverse rod, two pivot members and two wall-mounted brackets. The curved transverse rod has two ends which are connected to hollow pipe portions of the pivot members, respectively. Each pivot member includes a flat rounded end with a semi-circle flange at one end thereof. Each wall-mounted bracket includes a central protruding post which is inserted in a dual awl-shaped guide hole of the pivot member. The wall-mounted bracket further has a pair of lock holes for insertion of screws to be secured on a wall, a recess corresponding in shape to the flat round end, two stoppers to stop the semi-circle flange, and a protruding opening to receive the flat rounded end and the semi-circle flange of the pivot member. A second headless screw is screwed in a second threaded hole of the flat rounded end to engage with the concave pivot point. A first headless screw is screwed in a first threaded hole of the pivot member to engage with the ends of the curved transverse rod.
