Sprinkler Mounting Bracket Positioning Groove and Protrusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sprinkler mounting devices face issues with the open-type mounting bracket separating from the support bar during operation, particularly when the user needs to mount a reducer with a larger head, leading to discomfort and difficulty in handling and manufacturing due to the requirement for separate components and bent support units.
Innovation Solution
A sprinkler mounting device featuring an open-type mounting bracket with upper and lower plates, a retaining jaw portion, an elastically bent portion, and a tightening screw, which allows for secure attachment to the support bar, preventing separation and enabling convenient mounting without regard to the type of support units or support bar.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the open-type mounting bracket is used to allow front fitting of the reducer, then the ease of operation is improved, but the mounting bracket may separate from the support bar during mounting work
Solution Approach 1:
A positioning protrusion on the mounting bracket fits into a positioning groove on the support bar, creating an intermediary mechanical connection that prevents separation while allowing front fitting operation. This intermediary structure resolves the contradiction by providing both operational accessibility and positional stability.
Solution Approach 2:
The mounting bracket is designed with an L-shaped configuration, adding a dimensional aspect to the connection. The vertical plate extends downward from the horizontal plate, creating a three-dimensional structure that engages with the support bar in multiple directions, preventing separation while maintaining front accessibility.
2Reliability
If the closed-type mounting bracket is used to prevent separation, then the reliability is improved, but the ease of operation deteriorates as the user must work in an upward-looking posture
Solution Approach 1:
Instead of requiring the user to look upward at a closed-type bracket, the design inverts the approach by using an open-type bracket with front accessibility. The positioning groove and protrusion mechanism provides the necessary stability without requiring an upward-looking posture, reversing the traditional design paradigm.
3Reliability
If the support units are made integral with the support bar, then the reliability is improved by preventing separation, but the device complexity increases due to bent portions and manufacturing difficulty
Solution Approach 1:
The mounting bracket is segmented into a horizontal plate and a vertical plate connected at a right angle. This segmentation allows the bracket to be manufactured from a standardized rectangular bar without requiring complex bending operations, while still providing the structural integrity needed to prevent separation.
Solution Approach 2:
The positioning groove on the support bar serves multiple functions: it guides the positioning protrusion during assembly, maintains proper alignment, and prevents separation during operation. This multi-functional design element reduces overall device complexity while maintaining reliability.
4Ease of manufacture
If the support bar and support units are manufactured separately, then the ease of manufacture is improved, but the mounting bracket may separate from the support bar during mounting work
Solution Approach 1:
The positioning protrusion and positioning groove act as intermediary elements that connect the separately manufactured support bar and mounting bracket. This mechanical intermediary ensures reliable connection without requiring integrated manufacturing, allowing both components to be produced independently using standardized processes.
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 solution allows for secure and rapid sprinkler mounting by restricting the mounting bracket's position with the elastically bent portion and vertical face, preventing separation from the support bar, thus enhancing operational convenience and structural durability.
Implementation Method 1
an elastically bent portion formed in such a way that a portion formed by the cut portion is bent to have front and rear inclined faces
