Valve Seat Breakaway Coupling for Plumbing Orientation Errors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valve systems for plumbing, such as shower setups, face installation errors where hot and cold water inlets are incorrectly connected, leading to delays and additional costs when errors are discovered after the base is built-in, and pose challenges in tight spaces where correct orientation is difficult.
Innovation Solution
A valve system with a housing and seat configuration that ensures correct fluidic connections by requiring the housing to couple in a specific position, featuring a breakaway part that allows intentional reconfiguration if incorrect connections are detected, ensuring correct operation without altering the base's water network connections and aiding in orientation identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base is built-in with fixed connections to water inlets, then the installation structure is stable and simple, but installation errors cannot be corrected without extracting the base
Solution Approach 1:
The seat is divided into a fixed part and a breakaway part. The breakaway part can be intentionally detached to change the coupling position of the housing relative to the base, allowing correction of installation errors without extracting the base from the wall.
Solution Approach 2:
The breakaway part is pre-configured on the seat during manufacturing. This preliminary design enables the fitter to correct installation errors by simply breaking the breakaway part, without needing to extract the base or perform complex reconfiguration operations.
2Reliability
If the housing is designed to couple in a specific position only, then correct fluidic connections are ensured, but installation flexibility in tight spaces is reduced
Solution Approach 1:
The coupling position of the housing is made dynamically changeable through the breakaway part mechanism. Initially, the seat structure guides the housing to couple in the correct position (first coupling position). If needed, the breakaway part can be detached to allow coupling in an alternative position (second coupling position), providing adaptability while maintaining reliability.
Solution Approach 2:
The physical state of the seat is changed by breaking the breakaway part. This parameter change (from intact to broken) transforms the coupling constraints, allowing the housing to be installed in different positions depending on the installation context and space availability.
3Reliability
If the seat structure enforces correct coupling position, then installation errors are prevented, but the device complexity increases
Solution Approach 1:
The breakaway part is designed as a disposable element that serves its purpose during installation and can be broken when needed. This simple, sacrificial component adds minimal complexity to the seat structure while effectively enabling error prevention and correction capabilities.

AI summary
Device for a valve system, comprising: a housing with a seat for being coupled to a base and exchanging water streams when the housing is in a first coupling position, the seat comprising a first seat opening fluidly connecting to a first base opening when the housing is in the first coupling position; an adjuster which is contained inside the housing for adjusting the flow rate of one of the water streams; and a controller for controlling the adjuster. To avoid any complications in the event of an error while making the system more versatile, the seat comprises a breakable portion which can be broken off from the seat to enable it to be coupled in a second coupling position, the first seat opening subsequently fluidly connecting to a second base opening.
