Faucet Valve Two-Way Automatic Repositioning Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bi-temperature water faucets pose a safety risk, particularly for young and elderly users, as the valve does not reposition to a neutral state when turned off, potentially causing burns when the water is turned on again.
Innovation Solution
A faucet valve structure incorporating a base ring, resilient spring, and linking component that repositions the brake valve shaft to a middle section, ensuring safety by automatically resetting to a neutral position regardless of the water temperature when the faucet is turned off.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional bi-temperature water faucet is used, then the structure is simple and easy to manufacture, but the valve does not reposition to a neutral state when turned off, creating safety risks for users
Solution Approach 1:
The patent implements nesting by placing the repositioning device inside the valve structure. The resilient spring, base ring, and activating ring are nested within the valve body, with the resilient spring (60) housed inside the base ring (50), and the activating ring (70) rotating within the base ring. This nested arrangement adds the safety repositioning function without significantly increasing the overall device footprint or complexity.
Solution Approach 2:
The patent applies self-service through the resilient spring mechanism that automatically repositions the valve shaft to a neutral position when the faucet is turned off. The resilient spring (60) stores energy during valve operation and automatically releases it to return the valve to a safe middle position, eliminating the need for external control systems or additional power sources while ensuring user safety.
2Reliability
If an automatic repositioning structure is added to the faucet, then user safety is improved by preventing burn injuries, but the device complexity increases
Solution Approach 1:
The patent applies inversion by reversing the conventional approach: instead of requiring the user to manually return the valve to a cold position for safety, the system automatically returns to a neutral middle position using the resilient spring mechanism. The activating ring (70) and base ring (50) work together to invert the control flow, with the spring-driven mechanism autonomously resetting the valve state after each use.
Solution Approach 2:
The patent uses the resilient spring (60) as an intermediary element between the valve shaft and the neutral position. The spring acts as a mediator that stores and releases mechanical energy to facilitate the automatic repositioning of the valve shaft (30) to the middle position, enabling safe automatic resetting without direct mechanical linkage to external control systems.
3Ease of operation
If the valve remains in hot water mode when turned off, then the structure is simple, but young and elderly users are at risk of burn injuries
Solution Approach 1:
The patent applies preliminary action by pre-configuring the resilient spring (60) to automatically return the valve shaft (30) to a safe neutral position when the faucet is turned off. This preliminary safety mechanism is built into the valve structure, ensuring that regardless of whether the faucet was last used for hot or cold water, it automatically resets to a middle position that prevents burn injuries before the next use.
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 effectively prevents burn injuries by ensuring the faucet resets to a safe position, enhancing user safety across various user demographics.
Implementation Method 1
a resilient spring (60), which has a first effector (61) and a second effector (62)

AI summary
The faucet valve structure of two way automatic repositioning function includes a base ring, resilient spring, activating ring, and linking component. The base ring has a protruding block placed thereon. The resilient spring is placed on the base ring, which includes a first and second effector. The activating ring is placed on the resilient spring, which includes a first support that corresponds to the protruding block and a second support that corresponds to the second effector. The linking component is placed on the top end of the rotary base, and it has a crosswise protruding extension. When the user is using the faucet, whether it is on hot water mode or cold water mode, the brake valve shaft can be repositioned to the middle position, so that when the user is turning on the water regardless of warm or cold, it ensures safety from a burn injury.
