Gardening Fluid Coupling Sleeve With Open-Close Position Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gardening fluid connection devices are difficult to open and close, and it is not easy to determine whether they are in the opening or closing position, due to the lack of clear indicators and intuitive operation mechanisms.
Innovation Solution
A gardening fluid coupling device featuring a body with retainers, a resilient element, and a fitting sleeve with spaced engagement teeth and a stop rib, where the resilient element and locking elements facilitate easy opening and closing by rotating the fitting sleeve, with shoulders to maintain the closing position and release retainers from a water spray gun or sprinkler.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional fitting sleeve is rotated to open or close the device, then the device can be operated, but it is difficult to determine whether the device is in the opening or closing position
Solution Approach 1:
The patent employs visual indicators (such as colored regions or markings on the fitting sleeve and body) that change their relative positions or visibility states to indicate whether the device is in the opening or closing position. This allows users to quickly determine the device state without complex mechanical indicators.
Solution Approach 2:
The patent introduces an indicator mechanism that acts as an intermediary between the fitting sleeve position and the user's perception. This indicator translates the mechanical position into a visually distinguishable state, resolving the information loss problem.
2Device complexity
If the fitting sleeve is rotated without clear indicators, then the structure remains simple, but the user cannot easily distinguish between open and closed states
Solution Approach 1:
The patent uses visual indicators such as colored regions, markings, or contrasting colors on the fitting sleeve and body that become visible or change appearance based on the rotation position, providing clear state indication without adding complex mechanical components.
Solution Approach 2:
The patent divides the fitting sleeve or body into distinct visual segments or zones with different appearances (colors, patterns, or transparency) that correspond to different operational states, making position identification intuitive while maintaining structural simplicity.
3Ease of operation
If the fitting sleeve rotates freely without locking elements, then the operation is simple, but the device cannot maintain stable opening or closing positions
Solution Approach 1:
The patent incorporates locking elements that dynamically engage with the fitting sleeve at specific positions during rotation. These locking elements remain inactive during normal rotation but automatically engage at predetermined positions (open or closed) to maintain stability, providing both ease of operation and position stability.
Solution Approach 2:
The locking elements are designed to automatically engage and lock the fitting sleeve in the correct position without requiring additional user action. The device self-regulates its position stability through the interaction between the locking elements and the fitting sleeve's rotation.
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 device allows for easy operation by distinguishing the open or closed state through the interaction of the stop rib, locking elements, and resilient element, ensuring effortless connection and disconnection from water supply devices.
Implementation Method 1
a resilient element, wherein the fitting sleeve rotates along the body reciprocatingly and pushes the resilient element

AI summary
A gardening fluid connection device contains a body including multiple retainers, a resilient element, and a fitting sleeve including multiple spaced engagement teeth. The resilient element abuts against the body and the fitting sleeve. The body includes a stop rib, and the multiple spaced engagement teeth are pushed by the resilient element to abut against the stop rib. The body includes at least one retaining element, each retaining element is located on a first side of each spaced engagement tooth, and a width of each spaced engagement tooth is equal to a rotation distance of the fitting sleeve, hence the fitting sleeve is rotated reciprocatingly to open or close of the gardening fluid coupling device by using the stop rib, each retaining element, each spaced engagement tooth and the resilient element, and each retaining element is stopped when moving to a second side of each spaced engagement tooth.
