Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing explosion protection slides in pipelines face challenges with expensive maintenance, complex replacement of damping elements, and slower closing times due to the need for robust closure plates and inefficient damping mechanisms.
Innovation Solution
An explosion protection slide design featuring a laterally arranged deformation body, preferably a hollow tube made of aluminum, which dampens the closure plate's movement by being placed between the slide housing and the closure plate, allowing for lighter construction, faster closing times, and easier replacement, while preventing rebound through deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a robust closure plate is used to withstand impact forces, then the closure plate can reach the closed position without damage, but the closure plate becomes heavier and closing time increases
Solution Approach 1:
The patent applies beforehand cushioning by positioning deformation bodies (energy absorbers) in the closing path before the closure plate reaches the closed position. These deformation bodies are designed to deform plastically during closure, absorbing kinetic energy and reducing impact forces on the closure plate. This allows the use of a lighter closure plate that would otherwise be unable to withstand the high impact forces, thereby maintaining strength requirements while reducing weight and improving closing speed.
2Reliability
If expensive oil piston brakes are used to cushion the closure plate and prevent rebound, then the closure plate is protected from damage and rebound is prevented, but the system becomes very expensive
Solution Approach 1:
The patent implements this principle by using simple, inexpensive deformation bodies made from materials like aluminum, copper, or plastic instead of expensive oil piston brakes. These deformation bodies are designed to be deformed or destroyed during the closure process to absorb energy, serving as a cost-effective alternative to expensive reusable braking systems. The deformation bodies can be easily replaced after use, providing reliable closure plate protection at a fraction of the cost of oil piston brakes.
3Reliability
If damping elements are arranged in a stop area of the closure plate, then the closure plate can be cushioned, but the damping elements are difficult to replace after triggering
Solution Approach 1:
The patent applies this principle by extracting the damping function from the closure plate itself and placing separate, independent deformation bodies in the closing path. These deformation bodies are positioned laterally between the closure plate and slide housing, allowing them to be easily accessed and replaced without disassembling the closure plate or other critical components. This modular arrangement significantly simplifies maintenance and replacement procedures compared to integrating damping elements directly into the closure plate structure.
4Speed
If the closure plate is made lighter to reduce closing time, then closing speed improves, but the closure plate becomes more susceptible to damage from impact forces
Solution Approach 1:
The patent uses deformation bodies as intermediary elements between the moving closure plate and the stationary slide housing. These intermediaries absorb the impact energy through controlled deformation, protecting the lighter closure plate from damage while allowing it to maintain reduced mass for faster closing. The deformation bodies act as a buffer zone that mediates the energy transfer, enabling the system to achieve both light weight and durability.
