Shower Hinge Monoblock Design for Water Leakage and Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hinges for revolving shutters in shower boxes are aesthetically disappointing due to visible linear slots, complex construction leading to high wear and noise, and abrupt rotation, while also allowing water to escape, causing wet floors and safety issues.
Innovation Solution
A simplified hinge design with a single idle roller extending along the strike block, embedded elastic means, and a compact structure that minimizes visible gaps and enhances water-tightness, reducing noise and wear, and allowing smoother rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional hinges with multiple components (strike block, shaped flanges, idle roller, elastic means) are used, then the hinge can provide stable positioning and rotation functionality, but visible linear slots appear between components creating aesthetic discontinuity and allowing water leakage
Solution Approach 1:
The patent merges the strike block and shaped flanges into a single monoblock structure, eliminating the visible linear slots between separate components. This integration maintains the stable positioning function while achieving aesthetic continuity and preventing water leakage paths that existed between discrete parts.
Solution Approach 2:
The idle roller is nested within a recess of the monoblock structure, with elastic means positioned within the same monoblock. This nesting approach conceals the rotating components within the aesthetic form, eliminating visible gaps while maintaining functionality.
2Ease of operation
If traditional hinges with multiple discrete components are used, then the hinge provides rotation functionality, but the complex construction leads to high wear, noise, and abrupt rotation
Solution Approach 1:
By combining the strike block, shaped flanges, and supporting structure into a single monoblock, the patent reduces the number of discrete components that require assembly and maintenance. This simplification reduces wear points and noise sources while maintaining smooth rotation through the integrated design.
3Reliability
If traditional hinges with discrete components are used, then the hinge provides structural functionality, but water can escape through gaps causing wet floors and safety issues
Solution Approach 1:
The monoblock construction eliminates the linear slots and gaps that existed between discrete components in traditional hinges. This integration creates a continuous water-tight barrier while maintaining all necessary structural and rotational functionalities.
4Reliability
If traditional hinges with visible components are used, then the hinge provides mechanical functionality, but the aesthetic impact is disappointing due to visible linear slots and discontinuity
Solution Approach 1:
The patent integrates all mechanical components into a single monoblock structure with smooth, continuous surfaces. The idle roller and elastic means are concealed within recesses, eliminating visible linear slots and creating aesthetic continuity that matches modern shower design requirements while maintaining full mechanical functionality.

AI summary
An improved hinge (1; 100; 150; 200; 250; 300) for revolving shutters (A), especially of shower boxes, comprising a structural assembly which includes a strike block (2; 201) defining a substantially vertical main axis (Y) and suitable to be made integral with a fixed or bearing auxiliary structure (Α'), a pair of shaped flanges (3, 4; 103, 104; 203, 204; 203, 204) opposite, facing and coupled each other through fastening means (5) in such a way as to define a side recess (6) in which the strike block is substantially housed (2; 201), a side groove (7) which communicates with the outside and develops for at least part of the perimeter of the shaped flanges (3, 4; 103, 104; 203, 204; 253, 254) and is suitable to receive a peripheral portion of a revolving shutter (A) of a shower box, and an inner seat (8) hidden from view in which rotation means (9) are stably housed defining an auxiliary axis (Υ') parallel to the main axis (Y) of the strike block (2; 201) and cooperating, on one hand, with the strike block (2; 201) itself in such a way as to define a first operative position, in which the revolving shutter (A) closes, remaining stable in position, a room of the shower box, and at least one second operative position, in which the rotating shutter (A), as a result of rotation around the main axis (Y) imparted by a user, opens fully, remaining stable in position, the room of the shower box, and, on the other side, with elastic means (10) suitable to retain the rotation means (9) stably against the strike block (2; 201) at each of aforesaid operative positions. In particular, the elastic means (10) comprise an elastically yielding laminar body (11) shaped in such a way as to substantially embed in its own overall encumbrance the rotation means (9) which include a single idle roller (12; 156) extending for the entire height (H), defined parallel to said main axis (Y), of a head portion (13) of the strike block (2; 201), opposite to the base portion (14) associated with the fixed or bearing auxiliary structure (Α').
