Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sprinkler reducer fixing brackets require sequential operation to insert and lock the reducer vertically, making installation cumbersome and difficult from a standing position on a ceiling.
Innovation Solution
A sprinkler reducer fixing bracket design that allows the reducer to be easily pushed into a body, featuring a hook with inclined teeth and a locking pin, enabling automatic closure and secure locking with a simple pushing motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional sequential operation is used to insert and lock the reducer, then the reducer can be securely installed, but the installation process becomes cumbersome and difficult
Solution Approach 1:
The bracket is designed with a self-locking mechanism where the locking lever automatically engages with the locking hole when the reducer is inserted. The elastic deformation of the bracket body during insertion automatically triggers the locking action, eliminating the need for separate manual locking operations. This self-service mechanism directly resolves the contradiction by making the installation process simple while maintaining secure locking.
Solution Approach 2:
The bracket is pre-configured with the locking lever positioned to automatically engage with the locking hole during the insertion process. The inclined surface of the locking lever is designed to interact with the locking hole in advance, so that the locking action occurs naturally as part of the insertion motion rather than requiring a separate subsequent step. This preliminary arrangement of the locking mechanism resolves the operational complexity issue.
2Productivity
If automatic closure mechanism is implemented, then installation speed improves, but device structure becomes more complex
Solution Approach 1:
The locking lever and locking hole are integrated into a single automatic locking system where the lever's movement during insertion automatically triggers the locking engagement. The elastic deformation of the bracket body is combined with the locking mechanism motion, so that one insertion action simultaneously achieves both closure and locking functions. This merging of functions increases installation speed without proportionally increasing structural complexity.
Solution Approach 2:
The locking lever is designed with elastic properties, allowing it to dynamically deform during the insertion process and automatically engage with the locking hole. The dynamic motion of the lever during insertion creates the locking action automatically, transforming a static locking mechanism into a dynamic self-activating system. This dynamic approach enables automatic closure while keeping the structural additions minimal.
