Cam-Locking Sprinkler Bracket for Fast Secure Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing center brackets for fire-fighting sprinklers require complex assembly and disassembly processes, making it inconvenient to fix sprinklers securely to support frames without interruptions.
Innovation Solution
A bracket system with end brackets mounted to a support frame and a center bracket featuring a cam protrusion with an eccentric axis, allowing for pivotal movement to securely clamp the sprinkler without interrupting the assembly process, and a contact piece to ensure secure fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a center bracket with assembly and disassembly structure is used, then the bracket can be disassembled and reassembled, but the sprinkler fixing process becomes complicated and requires additional bolts and steps
Solution Approach 1:
The locking part integrates the clamping function and locking function into a single component that pivots about a hinge pin. The cam protrusion on the locking part directly engages with the sprinkler support frame, eliminating the need for separate bolts and assembly steps while maintaining the ability to disassemble and reassemble the bracket.
Solution Approach 2:
The locking part is designed to pivot dynamically about the hinge pin, allowing the cam protrusion to move from an engaged position (securing the sprinkler) to a disengaged position (allowing disassembly). This dynamic movement simplifies the fixing process while maintaining security during operation.
2Reliability
If a traditional center bracket is used, then the sprinkler can be fixed securely, but the mounting and dismounting process requires interruption and additional fastening steps
Solution Approach 1:
The locking part is pre-configured with the cam protrusion positioned to engage with the sprinkler support frame. When the bracket is assembled, the locking part is already in the correct position to secure the sprinkler immediately, eliminating the need for additional fastening steps and reducing mounting time while maintaining secure fixation.
3Strength
If the center bracket is designed to fix the sprinkler securely, then the connection is strong, but the assembly process becomes more complex with multiple components
Solution Approach 1:
The locking part combines multiple functions (clamping, locking, and securing) into a single component that pivots about the hinge pin. The cam protrusion on this integrated locking part directly engages with the sprinkler support frame, providing strong connection strength while reducing the number of separate components and simplifying the overall assembly.
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
Enables rapid and secure fixation of sprinklers with reduced assembly complexity, preventing damage and easy mounting of components, while maintaining an open side portion for convenience.
Implementation Method 1
The locking part includes a cam lever and a cam protrusion having an eccentric axis. The sprinkler fitted in the center bracket is directly pressurized and clamped by the cam protrusion by pivoting the locking part about the hinge pin
Implementation Method 2
As the cam lever coupled to the center bracket pivots, the cam protrusion of the cam lever causes the contact piece coupled to the center bracket to move linearly so that the sprinkler is securely clamped by a concave portion of the contact piece
