Sprayer Holder with Elastic C-Clip for Wear Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sprayer actuating and holding devices are not durable due to worn-out plastic components and are inconvenient to operate, with limited space making it difficult to engage and disengage the locking mechanism.
Innovation Solution
A device with a holder featuring a clamp with jaws and a gap, an elastic element, and a trigger that allows easy engagement and disengagement of the sprayer neck, enhancing the clamping mechanism with an elastic C-clip for improved durability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the engagement element is made of plastic, then the device is easy to manufacture, but the cam surfaces are worn away after some time of use so that the contact between the external edge of the engagement element and the internal edge of the locking ring is loose
Solution Approach 1:
The engagement element is constructed using composite materials, specifically a plastic body with an metal reinforcement insert. This combination provides the ease of manufacture and molding advantages of plastic while incorporating the durability and wear resistance of metal, directly resolving the contradiction between ease of manufacture and reliability
Solution Approach 2:
Instead of making the entire engagement element from metal, the reinforcement insert is strategically placed only in the critical areas where wear occurs (the cam surfaces and engagement edges). This localized reinforcement maintains the overall lightweight and easy-to-manufacture plastic structure while providing enhanced durability where needed
2Device complexity
If the locking ring is arranged around the engagement element after the engagement element is arranged around the rim, then the device can function, but the area of the locking ring and that of the engagement element are limited and render it difficult to operate
Solution Approach 1:
The engagement element is designed with a three-dimensional structure that includes protrusions extending axially from the rim. The locking ring engages with these protrusions in a different spatial dimension, allowing operation space to be utilized more effectively and enabling easier actuation despite the constrained radial space
3Ease of manufacture
If the engagement finger is pushed to insert or remove the locking ring, then the device can be assembled, but space around the engagement finger is limited and renders it difficult to operate
Solution Approach 1:
The engagement finger is designed as a resilient (elastic) component that can deflect and return. This dynamic characteristic allows the finger to be pushed for engagement/disengagement and then automatically return to its original position, making operation easier despite limited space, as the resilient nature provides tactile feedback and reduces the force required for actuation

AI summary
A device for holding and actuating a sprayer includes a holder and a trigger. The sprayer includes a neck, a rim formed on the neck, a push-button valve and a nozzle provided on the push-button valve. The holder includes a handle, a barrel extending from the handle and a clamp extending from the barrel. The clamp includes two jaws formed thereon, a mouth defined between the jaws and a gap defined between the jaws. The neck of the sprayer can be pushed into the mouth through the gap. The trigger is connected to the holder so that the trigger is operable to push the push-button valve of the sprayer.
