Device for adjusting a door and shower cubicle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door adjustment mechanisms for shower cubicles and enclosures, such as those using clamping rings and screws, suffer from play issues and water ingress, leading to unreliable adjustment and contamination, especially due to soap residue and limescale, which compromises the functionality over time.
Innovation Solution
A device featuring a bearing part with beveled rocker-like surfaces and a pre-tensioned tensioner, such as a spring steel or compression spring, allows for stepless and play-free angle adjustments using an adjusting screw, ensuring the door can be reliably moved from any angular position to open or raised states without compromising the seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a clamping ring is used to secure the lifting sleeve, then the door position can be adjusted, but the connection develops play and allows water ingress over time
Solution Approach 1:
The adjustment mechanism is divided into separate functional elements: the bearing lifter with rocker surfaces for adjustment, and the bearing part with sealing surfaces for secure mounting. This segmentation allows each component to perform its specific function optimally without the compromises of the integrated clamping ring design.
Solution Approach 2:
The sealing function is extracted from the mechanical connection function. The patent introduces a dedicated sealing element that prevents water ingress independently of the adjustment mechanism, thereby maintaining connection stability while preserving adjustability.
2Stability of the object's composition
If the clamping ring is pulled together to secure the lifting sleeve, then the door position is fixed, but the gap to the hinge plate increases causing play
Solution Approach 1:
The bearing lifter is designed with rocker-like surfaces that enable dynamic adjustment to any angular position. The pre-tensioned tensioner maintains constant contact pressure between the bearing lifter and bearing part, ensuring precise positioning without the need to increase gaps during securing.
Solution Approach 2:
The patent changes the geometric parameters of the contact surfaces between the bearing lifter and bearing part. The specifically designed rocker surfaces and complementary contact surfaces ensure that the bearing lifter can be secured in any angular position while maintaining optimal contact and eliminating play.
3Ease of operation
If the fitting structure is open upward to allow adjustment, then the door can be adjusted, but water and contaminants can enter causing malfunction
Solution Approach 1:
A sealing element is introduced as an intermediary between the adjustment mechanism and the external environment. This sealing element prevents water and contaminants from entering the adjustment mechanism while allowing the bearing lifter to be adjusted to any angular position.
Solution Approach 2:
The patent converts the potential harm of water ingress into a benefit by designing the sealing system to work in conjunction with the adjustment mechanism. The sealing element is specifically designed to prevent contamination while maintaining the accessibility needed for adjustment operations.
4Stability of the object's composition
If a clamping screw is used for adjustment, then the angular position can be fixed, but marks are left on bearing parts preventing subsequent adjustment
Solution Approach 1:
The patent replaces the clamping screw mechanical system with a pre-tensioned tensioner system combined with rocker surfaces. This substitution eliminates the need for marks on bearing parts, as the tensioner maintains constant contact pressure without leaving marks that would prevent subsequent adjustment.
