Shower Screen Hinge Band With Movable Seal for Low-Resistance Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shower partition walls with hinges experience increased resistance and reduced seal lifespan due to the arrangement of seals, making opening and closing difficult and compromising splash water tightness.
Innovation Solution
The design allows for relative mobility of sealing elements with respect to the hinge edges, ensuring they adapt to the door's rotational position and provide space adjustments, using L-shaped profiles and conical disc fastening for easy installation and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the seal is arranged on the door element and/or the floor, then splash water tightness is achieved, but opening and closing resistance increases and seal service life decreases
Solution Approach 1:
The patent applies the dynamics principle by making the sealing element movable relative to the hinge wing through a slot arrangement. The sealing element can dynamically adjust its position along the slot during door opening and closing operations, allowing it to adapt to changing spatial requirements and reduce friction resistance while maintaining effective sealing when the door is closed.
2Device complexity
If the hinge is arranged in a recess in the wall element or door element, then compact design is achieved, but sealing the hinge area becomes difficult
Solution Approach 1:
The patent merges the sealing function with the hinge structure by integrating the sealing element directly into the hinge wing. The sealing element is arranged on the hinge wing and works in conjunction with the recess arrangement, combining the hinge's rotational function with the sealing function in a single integrated component system.
Solution Approach 2:
The sealing element acts as an intermediary between the hinge mechanism and the recess arrangement. It is guided by the slot in the hinge wing and makes contact with the wall element or door element to provide sealing, mediating between the mechanical hinge movement and the sealing requirement.
3Reliability
If the sealing element is fixed in position, then sealing position is maintained, but it impedes door element movement during opening and closing
Solution Approach 1:
The patent implements dynamics by allowing the sealing element to move relative to the hinge wing through a slot arrangement. This movement capability enables the sealing element to adapt its position during door opening and closing operations, reducing friction and movement resistance while maintaining effective sealing contact when the door is in the closed position.

AI summary
The screen (1) i.e. shower screen (2), has a door element (4) rotatably supported at a wall element (3) by hinge bands (8, 9). A rotation movement of the door element overlies against the wall element by an axial movement of the door element in direction of a rotation axis (d). The axial movement is generated by blades (8a, 8b) of the bands. A recess (5) is dimensioned, such that blade is movable in the recess between a lower position (I) and a raised position in direction of the rotation axis, where the wall element and the door element are formed as plates made of security glass.
