Sprayer Holder Clamping Section with C-Shaped Spring Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sprayer holder devices are not durable due to plastic engagement elements that wear out quickly, and are inconvenient to operate due to limited space and design limitations, making it difficult to engage and disengage the locking ring and engagement element.
Innovation Solution
A holder apparatus with a clamping section featuring jaw portions, inner and outer rim portions, and a C-shaped grip element that securely grips the sprayer neck and supports the rim, along with a trigger element for operating the push-button valve, providing improved durability and ease of use through a more efficient design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a plastic engagement element with cam surfaces is used, then the device can be manufactured easily and成本低, but the cam surfaces wear away quickly reducing reliability
Solution Approach 1:
The engagement element is constructed from composite materials including a resilient member (elastic material) and a rigid member (metal or rigid plastic), combining the advantages of both materials to achieve both ease of manufacture and high reliability through wear resistance
Solution Approach 2:
The resilient member provides dynamic elasticity that compensates for wear over time, maintaining engagement reliability while the overall structure remains simple and easy to manufacture
2Device complexity
If the locking ring and engagement element are arranged in limited space, then the device structure is compact, but it becomes difficult to operate the locking ring and engagement element
Solution Approach 1:
The resilient member provides dynamic movement capability within the compact structure, allowing the engagement element to flex and move freely during engagement and disengagement operations despite space constraints
Solution Approach 2:
The engagement element is divided into distinct functional segments (resilient member and rigid member) that can move independently, improving operability within limited space
3Ease of operation
If the engagement finger is pushed repeatedly for engagement and disengagement, then the device is functional, but the limited space around the engagement finger makes operation difficult and tiring
Solution Approach 1:
The resilient member automatically provides return force after engagement finger actuation, eliminating the need for complex return mechanisms and reducing operational effort while maintaining simple device structure
Solution Approach 2:
The resilient member serves itself by automatically returning to its original position after deformation, providing self-reset functionality that simplifies operation without adding device complexity

AI summary
A holder apparatus includes a handhold formed on an end thereof for holding and a barrel section extending from another end thereof. A clamping section is formed from the front end of the barrel section opposite to the handhold and includes two jaw portions joined together, two limited grooves respectively formed in and extending along the two jaw portions, two inner rim portions respectively defined against the two limited grooves and two clamping edges respectively formed on the inner wall of the two jaw portions related to the two limited grooves. The clamping edges grip a neck of a sprayer and support the bottom of a rim of a sprayer. A trigger element is pivotally connected to the barrel section. A C-shaped spring is disposed in the two limited grooves and grips the inner rim portions related to the two clamping edges.
