Hollow Sprinkler Button Ridge Structure for Fire-Resistant Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sprinkler buttons made from materials like stainless steel, phosphor bronze, or copper are susceptible to deformation, leaks, or cracks under fire conditions due to reduced material strength and rigidity when made hollow, and require effective ejection from fluid flow paths.
Innovation Solution
The sprinkler button design incorporates a body with a ridge and cavities, a tab wall with tabs, and a hollow chamber, providing structural integrity and ensuring proper ejection by using a harder insert secured by the tabs to contact the frame, reducing material usage while maintaining rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If the sprinkler button is made hollow to reduce material usage, then material consumption and weight are reduced, but structural integrity and rigidity deteriorate causing deformation and leaks under fire conditions
Solution Approach 1:
The sprinkler button employs local quality by implementing a composite structure where a harder insert material is placed specifically in the regions requiring enhanced strength and rigidity (such as the sealing surfaces and load-bearing areas), while the main body remains hollow to reduce overall material consumption. This localized reinforcement resolves the contradiction by providing strength where needed without sacrificing the weight reduction benefits of the hollow design.
Solution Approach 2:
The invention applies composite materials by combining a base hollow button structure with a harder insert material. The composite construction allows the sprinkler button to achieve both reduced material usage (from the hollow design) and improved structural integrity (from the harder insert), directly resolving the technical contradiction between material reduction and strength maintenance under fire conditions.
2Loss of substance
If the sprinkler button is made hollow to reduce material usage, then material consumption and weight are reduced, but resistance to deformation and cracking under fire conditions deteriorates
Solution Approach 1:
The harder insert is strategically positioned in critical areas of the hollow sprinkler button to provide localized reinforcement against deformation and cracking. This ensures that the regions most susceptible to fire-induced stress receive enhanced protection, maintaining reliability while preserving the material reduction benefits of the hollow construction.
Solution Approach 2:
The composite material system combines the lightweight hollow structure with a harder, more fire-resistant insert material. This composite approach directly addresses the contradiction by providing the deformation and crack resistance needed for reliability under fire conditions while maintaining the reduced material consumption of the hollow design.
3Productivity
If the sprinkler button uses a harder insert secured by tabs to contact the frame, then ejection efficiency improves, but device complexity increases
Solution Approach 1:
The harder insert is segmented into a separate component that can be independently manufactured and then secured to the hollow button body using tabs. This segmentation allows for optimized ejection performance through the harder material while keeping the overall device complexity manageable through modular assembly. The tabs provide a simple yet effective connection mechanism that minimizes assembly complexity.
Solution Approach 2:
The tabs act as intermediary elements that connect the harder insert to the hollow button body. These tabs serve as a simple mechanical interface that enables effective ejection (by securing the harder material that contacts the frame) without requiring complex fastening mechanisms, thus improving ejection efficiency while limiting the increase in device complexity.
