Valve Core Seat Bypass Structure for Solenoid Switch Failure

Solution Overview

Problem

Induction taps with solenoid valve switches face issues where damage leads to constant water flow or inability to control water outlet, necessitating replacement and increased maintenance costs.

Innovation Solution

A core seat and valve core module design that allows for switching to an ordinary tap function when the electric control switch is damaged, using a water path switching valve core with a base and transition passages to redirect water flow, enabling continued functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a solenoid valve switch is used for induction water outlet control, then the tap can be controlled without contact and the tap surface can be kept clean, but when the solenoid valve switch is damaged the induction water outlet cannot be achieved and the tap cannot be used normally

Engineering Contradiction:

Improvecontactless controlVSAvoidfunctionality after damage

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The water outlet control system is segmented into two independent paths: an electrically controlled path (first water outlet passage controlled by solenoid valve) and a manual mechanical path (second water outlet passage controlled by valve core). This segmentation allows the system to switch between automatic induction mode and manual mode, ensuring that damage to the solenoid valve does not completely disable the tap functionality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system changes the control parameter from purely electrical (solenoid valve) to mechanical (valve core position) when the electrical control fails. By providing an alternative control mechanism with different operational parameters, the system maintains functionality even when the original electrical control path is damaged.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If a multi-functional valve core is used to adjust water temperature and control water path, then the tap functions are integrated, but when the electric control switch is damaged the tap still cannot be used normally

Engineering Contradiction:

Improveintegrated functionsVSAvoidfunctionality after damage

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The water outlet control system is segmented into two independent paths: an electrically controlled path (first water outlet passage controlled by solenoid valve) and a manual mechanical path (second water outlet passage controlled by valve core). This segmentation allows the system to switch between automatic induction mode and manual mode, ensuring that damage to the solenoid valve does not completely disable the tap functionality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent prepares for potential solenoid valve failure by pre-designing a manual bypass path. The second water outlet passage and corresponding valve core are installed in advance as a backup mechanism, so when the electrical control fails, users can immediately switch to manual operation without needing additional components or complex repairs.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

3Extent of automation

If the tap is designed as an induction tap with electric control switch, then automatic water outlet control is achieved, but replacement is needed when the switch is damaged increasing use cost

Engineering Contradiction:

Improveautomatic controlVSAvoidmaintenance cost

Core Design Contradiction:

Extent of automationVSEase of manufacture

Solution Approach 1:

The water outlet control system is segmented into two independent paths: an electrically controlled path (first water outlet passage controlled by solenoid valve) and a manual mechanical path (second water outlet passage controlled by valve core). This segmentation allows the system to switch between automatic induction mode and manual mode, ensuring that damage to the solenoid valve does not completely disable the tap functionality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The manual valve core mechanism enables users to service the tap themselves when the electrical control fails. By providing a simple mechanical bypass that does not require specialized knowledge or tools, the system allows end-users to switch to manual mode and continue using the tap without professional maintenance intervention.

Inventive Principle:

Principle #25Self-service
