Side Sprayer Locking Assembly for Quick Flow Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional accessory sprayers for faucets either lock into place inefficiently or require continuous button activation, lacking a quick and efficient way to switch between normal and locked configurations.
Innovation Solution
A side sprayer assembly with three buttons allows users to transition between inactive, normal active, and locked active configurations, utilizing pistons and a locker mechanism to control fluid flow, enabling efficient operation without continuous button pressing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional accessory sprayer locks into place, then the sprayer can maintain fluid flow without continuous button activation, but the switching between configurations becomes inefficient and complex
Solution Approach 1:
The sprayer implements three dynamic configurations (inactive, momentarily active, and continuously active) that allow the user to quickly switch between different operational states. The momentarily active configuration enables temporary fluid flow when the button is pressed, while the continuously active configuration maintains flow without continuous button activation, resolving the contradiction between ease of activation and switching time.
Solution Approach 2:
The control mechanism is segmented into distinct configurations with dedicated buttons for each state. The first button controls transition between inactive and momentarily active states, while the second button controls transition to continuously active state. This segmentation allows users to select the appropriate configuration quickly without complex switching procedures.
2Loss of time
If a conventional accessory sprayer requires continuous button activation, then the configuration switching is simple, but the operation becomes inefficient and cumbersome
Solution Approach 1:
The sprayer provides a continuously active configuration where the first piston remains in the fluid flow permitting position without requiring continuous button pressure. This dynamic state maintains fluid flow while eliminating the need for continuous user activation, making the sprayer more efficient for extended use while keeping configuration switching simple.
3Ease of operation
If a locking mechanism is added to maintain piston position, then the sprayer can operate without continuous button activation, but the device complexity increases
Solution Approach 1:
The locking function is segmented into two separate buttons with distinct functions. The first button controls the activation state (inactive vs. momentarily active), while the second button controls the locking state (unlocked vs. continuously active). This segmentation simplifies the overall device complexity by assigning specific functions to dedicated controls rather than requiring a complex multi-function mechanism.
Solution Approach 2:
The patent introduces intermediary components including a locker that can engage with the first piston to maintain its position, and a diverter that works with the second piston to control fluid flow paths. These intermediary elements enable the locking and continuous activation functions while keeping the overall device structure manageable and understandable.
4Adaptability or versatility
If multiple buttons and pistons are used to control fluid flow configurations, then the sprayer offers multiple operational states, but the device complexity increases
Solution Approach 1:
The control system is segmented into two independent button-piston pairs, each handling specific configuration transitions. The first button and first piston manage the inactive/momentarily active states, while the second button and second piston (with diverter) manage the continuously active state. This segmentation provides three distinct configurations while maintaining a relatively simple and modular device structure that is easy to understand and operate.
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
Enables users to quickly and efficiently switch between configurations, enhancing usability by allowing fluid flow without continuous button activation and maintaining flow in a locked position.
Implementation Method 1
The first piston in the first position prevents fluid flow through the waterway from an inlet to an outlet, and the first piston in the second position permits fluid flow through the waterway from the inlet to the outlet
Implementation Method 2
a first spring is operably coupled with the first piston to bias the first piston toward the lever
Implementation Method 3
A diverter defines a piston opening and a spring operably coupled to the diverter to bias the diverter away from the locker
Implementation Method 4
The second piston including a cam surface in selective contact with the diverter
