Solution Overview

Problem

Conventional flushing water distributors fail to optimally direct water into rimless toilet bowls, leading to water splashing or overflowing, particularly in sanitary ware with non-traditional designs.

Innovation Solution

A flushing water distributor with a pipe element and a bearing surface that allows for precise alignment and mounting, ensuring optimal water distribution through aligned outlet openings, preventing twisting during use, and utilizing a seal for secure installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If conventional flushing water distributors are used, then the structure is simple and easy to manufacture, but the water distribution is not optimal leading to splashing or overflowing

Engineering Contradiction:
Improvewater distribution precisionVSAvoiddistributor structure complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The bearing surface is designed with an asymmetric non-circular shape that corresponds to the asymmetric bearing point in the receptacle. This asymmetric design ensures proper rotational alignment of the distributor, positioning the outlet openings correctly to direct water optimally into the toilet bowl and prevent splashing or overflowing.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The bearing surface is pre-shaped with a specific non-circular geometry during manufacturing that matches the bearing point. This preliminary design ensures that when the distributor is installed, it automatically assumes the correct rotational position without requiring additional alignment mechanisms or complex adjustment procedures.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If the flushing water distributor is designed with simple mounting, then installation is easy, but incorrect insertion or twisting can occur during use

Engineering Contradiction:
Improvemounting easeVSAvoidmounting reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The asymmetric bearing surface design provides a mechanical constraint that allows easy insertion while preventing incorrect rotational positioning. The shape complementarity between the bearing surface and bearing point ensures the distributor can only be installed in the correct orientation, eliminating the risk of incorrect insertion or twisting during use.

Inventive Principle:
Principle #4Asymmetry

3Manufacturing precision

If outlet openings are not optimally aligned, then manufacturing is simpler, but water is not directed optimally into the sanitary ware interior

Engineering Contradiction:
Improveoutlet alignment precisionVSAvoidbearing surface geometry
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The non-circular asymmetric bearing surface is designed with specific geometric features that, when engaged with the corresponding bearing point, automatically orient the outlet openings in the correct positions. This asymmetric coupling mechanism translates the simple act of insertion into precise angular alignment of the water discharge outlets.

Inventive Principle:
Principle #4Asymmetry
