Sleeve-Coupled Side Inlet Valve for Simpler Toilet Water Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing side water inlet valves have rigid structural features that limit appearance design and beauty, with complex structures and poor associative perception, and lack efficient water route design.
Innovation Solution
A side water inlet valve design featuring a sleeve-coupled water inlet body and outer sleeve pipe, forming a T-shaped water passage with seal rings and a simplified water route, allowing for detachable and aesthetically enhanced components, and incorporating a water stop assembly and anti-siphon mechanism for improved functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a rigid structural feature is used to meet uniform wall thickness requirements of injection molded parts, then manufacturing precision is improved, but appearance design flexibility deteriorates
Solution Approach 1:
The valve body is divided into multiple segments (first valve body segment, second valve body segment, third valve body segment) that can be independently designed and manufactured. This segmentation allows each segment to be optimized for its specific function while maintaining overall manufacturing precision through standardized connection interfaces.
Solution Approach 2:
The inner sleeve is nested within the valve body cavity, creating a multi-layer structure where the inner sleeve provides the water flow channel and the valve body provides structural support and connection functions. This nesting approach allows complex functionality to be achieved within constrained manufacturing dimensions.
2Device complexity
If the appearance structure is simplified, then device complexity is reduced, but associative perception deteriorates
Solution Approach 1:
The outer sleeve serves multiple functions simultaneously: it provides the external appearance, acts as a connection interface for the water supply pipe, provides structural support, and defines the overall valve geometry. This multi-functionality reduces the need for separate components while maintaining aesthetic design flexibility.
Solution Approach 2:
The connection interface for the water supply pipe is merged with the outer sleeve structure rather than being a separate component. The threaded connection is integrated into the outer sleeve's wall, combining the mounting function with the appearance structure to reduce overall device complexity.

AI summary
The invention discloses a side water inlet valve and a flush toilet, the side water inlet valve comprising a water inlet body provided with a water inlet channel, and a water outlet pipe provided with a water outlet channel, wherein, an outer sleeve pipe in communication with the water outlet pipe is fixed at the end of the water outlet pipe, and the water inlet body is sleeve coupled in the outer sleeve pipe from an opening at one end of the outer sleeve pipe, such that the water inlet body and the outer sleeve pipe are sleeve coupled and engaged. The water inlet body and the outer sleeve pipe are detachable, and a water flow channel is formed between the outer wall of the water inlet body and the inner wall of the outer sleeve pipe, through which the water inlet channel is in communication with the water outlet channel. With the above structure, the structure and appearance of the product are greatly adjusted compared with the existing side water inlet valve, and the appearance of the product is more beautiful, novel and holistic; moreover, some parts of the water inlet body of the existing side water inlet valve may be omitted by the use of the outer sleeve pipe, such that the product is simple in structure and good in assembly manufacturability, thereby achieving the effect of reducing the cost.
