Dispensing Device Spacing for Rimless Toilet Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing devices for cleaning agents in sanitary facilities, such as toilet bowls and urinals, disrupt water flow conditions, particularly in rimless toilet bowls, leading to complex flushing adjustments and inefficient surface coverage.
Innovation Solution
A dispensing device with a receiving element placed at a distance from the channel side wall, allowing water to flow around it, and a bearing strut to hold the element in place, minimizing flow resistance and maintaining consistent flow properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the dispenser protrudes into the pipe section perpendicular to the flow direction, then the cleaning agent can be dispensed into the water stream, but the flow patterns within the channel are negatively affected
Solution Approach 1:
The receiving element is repositioned from a perpendicular orientation to a parallel orientation with the flow direction, and is spaced away from the side wall to allow circumferential flow. This dimensional reconfiguration enables the water stream to flow around the receiving element on all sides, maintaining flow characteristics while still achieving cleaning agent dispensing.
Solution Approach 2:
The bearing strut acts as an intermediary element that positions the receiving element in the channel space at a controlled distance from the side wall. This intermediary structure enables the receiving element to be held in a position that optimizes flow characteristics while maintaining its function for cleaning agent dispensing.
2Device complexity
If the receiving element is positioned close to the side wall, then the device complexity is reduced, but the flow characteristics become complex and may cause overflowing or incomplete surface coverage
Solution Approach 1:
The bearing strut serves as an intermediary component that provides the necessary spacing between the receiving element and the side wall. This simple structural element achieves the optimal positioning without requiring complex adjustment mechanisms, thereby maintaining device simplicity while ensuring proper flow characteristics.
Solution Approach 2:
The invention specifies a particular spacing parameter between the receiving element and the side wall that optimizes flow characteristics. By controlling this dimensional parameter, the system achieves consistent flow patterns that prevent overflowing and ensure complete surface coverage.
3Productivity
If the receiving element is spaced circumferentially from the side wall, then the flow characteristics are improved with consistent flow patterns, but the device structure becomes more complex
Solution Approach 1:
The bearing strut is a simple intermediary component that achieves the circumferential spacing requirement. Rather than using complex positioning mechanisms, the bearing strut provides the necessary spacing in a straightforward structural manner, minimizing the increase in device complexity while achieving the desired flow characteristics.
Solution Approach 2:
The device is segmented into distinct functional components: the channel for water flow, the bearing strut for positioning, and the receiving element for cleaning agent dispensing. This segmentation allows each component to be optimized independently, with the bearing strut specifically designed to provide the necessary spacing without adding overall system complexity.

Function Achieved in This Case
The solution ensures better flow conditions and consistent flushing performance by allowing water to flow evenly around the dispensing element, improving the distribution of cleaning agents without obstructing the water stream.
