Sprinkler Reducer Fixing Bracket With Hinge Lever
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sprinkler systems face issues with the secure fastening and easy attachment/detachment of reducers due to the use of bolts, which lead to inadequate fastening force, tool dependency, and potential loss of bolts during adjustments.
Innovation Solution
A fixing bracket for sprinklers featuring a body with holes for mounting the reducer and a pressing lever that uses a hinge shaft to securely engage the reducer without bolts, allowing for one-touch fixation and separation, and an optional coupling assembly with an elastic member for enhanced fastening and tool-free operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bolts are used to fix the reducer, then the fastening can be achieved, but the fastening force deteriorates due to damage from tightening force and bolts loosen over time
Solution Approach 1:
The patent replaces the traditional bolt-based mechanical fastening system with a clamp-based friction grip system. The clamp applies continuous radial pressure to the reducer through friction, eliminating the need for bolts that cause damage during tightening and loosening. This substitution resolves the contradiction by providing reliable fastening without the strength-deteriorating effects of bolt tightening forces.
Solution Approach 2:
The patent changes the fastening mechanism from discrete bolt connections to continuous friction-based pressure. By adjusting the clamp's pressing force parameter, the system maintains optimal fastening strength without the cyclic loading and damage associated with bolt tightening and loosening, thereby improving both reliability and preserving strength.
2Reliability
If bolts are used to fix the reducer, then the fastening can be achieved, but it becomes troublesome to loosen and tighten fasteners for replacement
Solution Approach 1:
The patent replaces the complex bolt tightening/loosening system with a simple clamp release mechanism. The clamp can be quickly released and repositioned without tools, making replacement operations trivial while maintaining secure fastening during operation. This resolves the contradiction between reliable fastening and ease of operation.
Solution Approach 2:
The clamp mechanism is designed to be self-adjusting and tool-free, allowing operators to quickly attach and detach reducers without requiring specialized tools or complex procedures. The simple release mechanism enables rapid replacement while the friction-based grip ensures reliable fastening, simultaneously improving ease of operation and maintaining reliability.
3Reliability
If bolts are used to fix the reducer, then the connection can be made, but bolts are loosened by damage and fastening force deteriorates
Solution Approach 1:
The patent replaces the bolt connection system with a clamp-based friction system that applies continuous radial pressure. This eliminates the cyclic stress and damage accumulation that occurs with repeated bolt tightening and loosening, thereby maintaining both connection reliability and fastening stability over time.
Solution Approach 2:
The clamp mechanism provides continuous protective pressure on the reducer, preventing the damage accumulation that occurs with bolted connections. By maintaining constant friction-based grip, the system cushions against vibrations and movements that would otherwise loosen bolts and deteriorate fastening stability.
4Reliability
If bolts are used to fix the reducer, then the fastening can be achieved, but specific tools are required and bolts may be lost during separation
Solution Approach 1:
The patent replaces the tool-dependent bolt system with a tool-free clamp mechanism. The clamp can be easily attached and detached by hand, eliminating the need for wrenches or other tools, while maintaining reliable fastening through friction-based grip. This resolves the contradiction between reliability and device complexity.
