Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shower device three-way water distributors have a unified knob design that lacks novelty, is prone to damage due to moisture and repeated use, resulting in a short service life and increased size, with no compact and space-efficient switching valve available on the market.
Innovation Solution
A convenient switching valve with a main body, switching member, and positioning disc, featuring a switching chamber, first and second switching levers, water-stop parts, and a rotatable positioning disc with a spring mechanism, allowing for labor-saving operation and reduced maintenance, while maintaining a compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional three-way water distributor uses a unified knob design with an external handle to facilitate rotation, then the ease of operation is improved, but the device size increases and the reliability deteriorates due to moisture damage and repeated use
Solution Approach 1:
The invention divides the switching mechanism into separate components: a positioning disc with positioning grooves and switching levers with water-stop parts, eliminating the need for a unified external handle. Each component performs a specific function, improving reliability while maintaining ease of operation through rotational switching.
Solution Approach 2:
Instead of using an external handle that rotates to control water flow, the invention inverts the approach by using a positioning disc with grooves that guide internal switching levers. The switching action is reversed from external handle rotation to internal lever movement guided by the positioning disc, eliminating the vulnerable external handle.
2Ease of operation
If a conventional three-way water distributor uses a unified knob design with an external handle, then the ease of operation is improved, but the device complexity and size increase
Solution Approach 1:
The switching mechanism is segmented into a positioning disc with grooves and separate switching levers, each with specific functions. This segmentation simplifies the overall structure by eliminating the complex external handle mechanism while maintaining operational ease through the groove-guided lever system.
Solution Approach 2:
The positioning disc serves multiple functions: it guides the switching levers, provides positioning grooves for stable switching, and eliminates the need for a separate external handle. This multi-functionality reduces device complexity while maintaining ease of operation.
3Ease of operation
If a conventional three-way water distributor uses a unified knob design, then the ease of operation is improved, but novelty is reduced and adaptability to different user needs deteriorates
Solution Approach 1:
The invention introduces a novel segmented design with a positioning disc and multiple switching levers, providing design novelty while maintaining ease of operation. The segmented structure allows for better adaptability to different user needs compared to the unified knob design.
Solution Approach 2:
Different parts of the switching mechanism have specialized local qualities: the positioning disc provides rotational guidance, the positioning grooves ensure stable switching positions, and the water-stop parts provide sealing. This local specialization enhances both novelty and adaptability while maintaining ease of operation.
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
The solution provides a labor-saving, long-lasting, and space-efficient water control mechanism, where only the water-stop parts may wear out, reducing maintenance costs and extending the service life, while maintaining a compact structure.
Implementation Method 1
a spring is provided between the first switching lever and the first switching chamber, and the spring provides an elastic force to press the first switching lever toward the positioning disc
Implementation Method 2
The first water-stop part is sealingly fitted against an inner wall of the first switching chamber. The first water-stop part is movable to block a water passage between the water inlet and the first water outlet

AI summary
A convenient switching valve includes a main body, a switching member and a positioning disc. The main body is provided with a water inlet and at least one water outlet. The positioning disc is rotatably fitted at an end of the main body. The positioning disc cooperates with the switching member, enabling the switching member to be moved in the main body to block a water passage between the water inlet and the water outlet. By rotating the positioning disc, the positioning disc movably press the switching member to block the water passage, thereby realizing the control of the water flow of the water outlet. The operation is convenient and labor-saving.
