Insulated Explosion Panel Shell for Watertight Rupture Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing explosion panels with thermal insulation face issues such as loss of sealing integrity due to weather exposure, which compromises their effectiveness, and the manufacturing process is complex and time-consuming.
Innovation Solution
A thermally insulated explosion panel with a three-dimensional profiled rupture element, manufactured as a single piece, incorporates thermal insulation and ensures a continuous seal by housing insulating material within a shell that maintains a solid, continuous surface, preventing water infiltration and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a separate insulating box is added to the explosion panel, then thermal insulation is improved, but the sealing integrity deteriorates due to weather exposure damaging sealant joints
Solution Approach 1:
The patent merges the insulating box and explosion panel into a single integrated unit. The insulating material is directly coupled to the backside of the rupture sheet, eliminating separate sealant joints between components. This integration resolves the sealing integrity issue while maintaining thermal insulation benefits.
Solution Approach 2:
The rupture sheet serves multiple functions: it acts as both the explosion-resistant barrier and the mounting surface for thermal insulation. The single-piece construction provides both structural integrity for explosion containment and thermal insulation properties, reducing the need for additional sealing components.
2Temperature
If a separate insulating box with multiple attachment steps is used, then thermal insulation is improved, but manufacturing complexity increases
Solution Approach 1:
The patent combines multiple manufacturing steps into a single integrated process. The insulating material is coupled directly to the rupture sheet in one operation, eliminating separate box fabrication, assembly, and attachment steps. This reduces manufacturing complexity while achieving the same thermal insulation effect.
Solution Approach 2:
The patent segments the thermal insulation function from the complex box structure, applying insulation material directly to the rupture sheet surface. This simplification reduces the number of components and assembly steps required, directly addressing the manufacturing complexity issue.
3Temperature
If a separate insulating box is added to the explosion panel, then thermal insulation is improved, but the weight increases adding load to the rupture sheet
Solution Approach 1:
The patent uses a thin-film approach by coupling insulation material directly to the rupture sheet surface rather than adding a bulky box structure. This reduces the overall weight increase while maintaining effective thermal insulation, directly addressing the weight concern.
Solution Approach 2:
The insulating material is nested directly against the backside of the rupture sheet, creating a compact integrated structure. This nesting approach minimizes the volume and weight of additional materials required compared to a separate box structure, reducing the load on the rupture sheet.

AI summary
Explosion panel (1) comprising a rupture element (1') which includes a weakening zone (11) and a peripheral fixing surface (14), a clamping frame (3) arranged on the peripheral fixing surface without covering the weakening zone (11), and a thermally insulating material (2) coupled to the rupture element (1'). The rupture element (1') has a solid, continuous, three-dimensional profiled surface which is manufactured as a single piece, in particular by stamping, forming a shell providing an internal volume (V) in which the thermally insulating material (2) is housed.
