Solution Overview

Problem

Existing explosion panels require manual insertion of spacers to ensure proper tightening of seals, which can be overlooked, leading to compromised sealing and potential damage.

Innovation Solution

Integration of clamping adjustment means directly into the rupture sheet, eliminating the need for additional parts and ensuring balanced compression of seals through integrated bosses that provide resistance points during tightening.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If spacers are inserted into each mounting hole to control tightening, then seal compression is improved, but device complexity increases and reliability decreases due to human error risk

Engineering Contradiction:
Improveseal compression controlVSAvoidnumber of additional parts
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The adjustment means are integrated directly into the rupture sheet as molded-in bosses or raised sections, merging the adjustment function with the panel structure itself. This eliminates the need for separate spacer components and their insertion steps, reducing device complexity while maintaining precise seal compression control.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated bosses on the rupture sheet automatically provide the necessary adjustment reference during tightening. The system serves itself by having the adjustment means built-in, eliminating reliance on operator memory to insert external spacers, thereby improving reliability while maintaining manufacturing precision.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If spacers are used for tightening adjustment, then ease of operation is improved, but reliability decreases due to risk of oversight

Engineering Contradiction:
Improvetightening adjustmentVSAvoidseal compression consistency
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The adjustment means are built into the rupture sheet structure itself, eliminating the need for separate spacer components and their insertion steps. This self-integrated design ensures that the adjustment reference is always present and eliminates reliance on operator memory, thereby improving reliability while maintaining ease of operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The bosses or raised sections are pre-formed as integral parts of the rupture sheet during manufacturing. This preliminary integration ensures that the adjustment reference is already in place before installation, eliminating the risk of oversight during operation while maintaining ease of use.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If multiple separate adjustment components are used, then adaptability is improved, but device complexity increases

Engineering Contradiction:
Improvetightening controlVSAvoidnumber of interface parts
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adjustment means are merged with the rupture sheet as integral bosses or raised sections, eliminating the need for separate adjustment components. This integration reduces the number of interface parts and assembly steps while maintaining the adaptability of tightening control through the built-in reference features.

Inventive Principle:
Principle #5Merging (Combining)
