Urinal Top Cover Access for Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing urinal designs require disassembly for maintenance due to the placement of electrical components in a mounting cavity, making repairs inconvenient.
Innovation Solution
A urinal design with a mounting cavity at the top of the urinal body, featuring an openable top cover that allows for easy access to the power supply, electric-controlled water valve, and other equipment, eliminating the need to disassemble the urinal body for maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If electrical components are mounted in a mounting cavity on the rear side of the urinal body, then the appearance is compact and integrated, but maintenance requires disassembly of the urinal body which is inconvenient
Solution Approach 1:
The patent divides the mounting cavity into two accessible parts: the rear side cavity for electrical components and the front side cavity for the water valve assembly. This segmentation allows maintenance personnel to access different components from different sides without disassembling the entire urinal body, resolving the contradiction between integrated appearance and maintenance accessibility.
Solution Approach 2:
The patent introduces a removable panel or cover as an intermediary element that provides access to the mounting cavity. This intermediary structure allows the cavity to remain integrated in appearance while enabling convenient access to electrical components for maintenance, effectively resolving the contradiction between compact integration and ease of repair.
2Reliability
If the urinal spray head is mounted on the bowl wall or bottom plate, then it can effectively flush the urinal bowl surface, but the protruding nozzle affects the appearance
Solution Approach 1:
The patent embeds the spray head within a cavity formed in the bowl wall or bottom plate, nesting the functional component inside the structural body. This nesting approach allows the spray head to maintain its flushing function while being hidden within the urinal structure, eliminating the protruding appearance and resolving the contradiction between reliability and aesthetic shape.
Solution Approach 2:
The patent extracts the spray head from the external surface and relocates it to an internal cavity position. By taking out the protruding element and repositioning it within the structure, the solution maintains the flushing effectiveness while improving the appearance quality by eliminating visible protrusions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates convenient maintenance by allowing users to open the top cover for repairs without disassembling the urinal body, improving maintenance accessibility.
Implementation Method 1
a sensor is assembled on the ceramic body of the urinal or a wall, and when a user is detected to be standing in front of the urinal, the sensor sends a signal
Implementation Method 2
the controller automatically opens an electric valve controlling the opening and closing of the nozzle
