Gardening Fluid Coupling Sleeve Locking for Clear Open-Close Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gardening fluid connection devices are difficult to open and close, and users struggle to determine the device's position due to complex mechanisms involving fitting sleeves and stop ribs.
Innovation Solution
A gardening fluid connection device featuring a body with retainers, a resilient element, and a fitting sleeve with spaced engagement teeth and locking elements, where the resilient element pushes the fitting sleeve to open or close the device, allowing easy connection or disconnection from water spray guns or sprinklers, with a stop rib and locking elements facilitating the operation.
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 opened or closed, but it is difficult to determine the device's position and the operation is complex
Solution Approach 1:
The patent uses visual indicators (such as different colored regions or markings on the fitting sleeve and body) to clearly indicate the open and closed positions of the device. This allows users to immediately recognize the device state without complex mechanisms, resolving the contradiction by providing simple visual feedback that reduces operational complexity.
Solution Approach 2:
The resilient element automatically pushes the fitting sleeve to indicate its position, and the locking elements self-engage with the spaced engagement teeth. This self-indicating mechanism eliminates the need for complex external indicators or manual positioning, making the device easy to operate while maintaining simple structure.
2Reliability
If multiple locking elements and spaced engagement teeth are used, then the device can be securely locked, but the operation becomes more difficult and position indication is unclear
Solution Approach 1:
The locking mechanism is segmented into multiple independent locking elements and spaced engagement teeth that work in sequence. Each locking element corresponds to a specific engagement tooth, creating discrete locking positions that are easy to recognize and operate, thereby maintaining reliability while improving ease of operation.
Solution Approach 2:
The resilient element acts as an intermediary between the fitting sleeve and the locking elements. It transmits the rotational force smoothly and provides tactile feedback, making the multi-stage locking operation easy to perform while maintaining secure locking at each position.
3Adaptability or versatility
If the fitting sleeve is rotated reciprocatingly to connect or disconnect retainers, then connection and disconnection is achieved, but the position indication is not clear to users
Solution Approach 1:
The patent incorporates visual indicators such as colored regions on the fitting sleeve that align with corresponding regions on the body to clearly indicate connection and disconnection states. This provides immediate visual feedback to users, preventing loss of position information while maintaining the versatile connection function.
Solution Approach 2:
The resilient element provides tactile feedback during rotation, and the visual indicators provide continuous position feedback. This dual feedback mechanism ensures users always know the device state, eliminating information loss while maintaining the ability to connect and disconnect retainers easily.

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.
