Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional casings for electronic devices in explosion-prone areas lack sufficient structural strength to reliably reduce explosion pressure, risking damage or destruction and compromising certification requirements.
Innovation Solution
A pressure-resistant casing with a damping element surrounded by a stabilizing device, such as a wire mesh, to absorb and redirect explosion pressure, ensuring the casing's integrity and reducing gas molecule speed, thereby minimizing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If a damping element is used to reduce explosion pressure, then the explosion pressure is reduced, but the structural strength is insufficient causing damage or destruction
Solution Approach 1:
The patent combines a damping element (for pressure reduction) with a stabilizing device having mesh-like structure (for structural strength). This composite construction allows the damping element to reduce explosion pressure while the mesh structure prevents destruction, resolving the contradiction between pressure reduction and structural strength
Solution Approach 2:
The damping element is pre-installed in the casing to cushion against explosion pressure before an actual explosion occurs. This beforehand preparation allows the system to absorb and redirect explosion forces, reducing peak pressure while the mesh structure provides preemptive structural support
2Weight of stationary object
If the casing walls are made thinner to reduce weight, then the user friendliness increases, but the ability to withstand explosion pressure decreases
Solution Approach 1:
The combination of thin casing walls with the damping element and mesh-like stabilizing structure creates a composite system where the lightweight casing is compensated by the pressure-reducing and strength-providing internal components, achieving both weight reduction and explosion resistance
Solution Approach 2:
The mesh-like structure of the stabilizing device provides a porous framework that maintains structural integrity while allowing gas passage, enabling thin walls to withstand explosion pressures through the distributed support of the mesh structure
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
The solution effectively reduces explosion pressure, maintaining the casing's structural integrity and enabling certification for use in hazardous environments, even if the casing is damaged, by using a damping element with a mesh-like stabilizing structure to absorb and redirect gas expansion.
Implementation Method 1
The damping element having damping properties brings about a not inconsiderable reduction in the speed of the gas atoms or gas molecules in the event of an explosion
