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

VSEngineering 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

Engineering Contradiction:
Improvethermal insulationVSAvoidsealing integrity
Core Design Contradiction:
TemperatureVSReliability

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.

Inventive Principle:
Principle #5Merging (Combining)

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Temperature

If a separate insulating box with multiple attachment steps is used, then thermal insulation is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvethermal insulationVSAvoidmanufacturing process complexity
Core Design Contradiction:
TemperatureVSDevice complexity

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.

Inventive Principle:
Principle #5Merging (Combining)

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.

Inventive Principle:
Principle #1Segmentation

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

Engineering Contradiction:
Improvethermal insulationVSAvoidpanel weight
Core Design Contradiction:
TemperatureVSWeight of moving object

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.

Inventive Principle:
Principle #30Flexible shells and thin films

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.

Inventive Principle:
Principle #7Nested doll (Nesting)
