Solution Overview

Problem

Existing destruction systems for detonation-dangerous materials require complex and costly locking mechanisms to ensure safety and reliability, which are difficult to operate and prone to manufacturing inaccuracies and thermal issues.

Innovation Solution

A locking arrangement using elongated connection elements with mechanical actuators to clamp vessel portions together, eliminating the need for a locking ring, allowing for cost-effective materials and reduced manufacturing complexity, while ensuring a secure and gas-tight interconnection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a locking ring is used to interconnect vessel portions, then reliability and safety are improved, but device complexity and manufacturing cost increase

Engineering Contradiction:
ImprovesafetyVSAvoidcomplexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The locking ring is segmented into multiple discrete connection elements (e.g., bolts or lugs) distributed around the circumference of the vessel portions. Each connection element independently contributes to the clamping force, allowing the system to achieve reliability through distribution rather than relying on a single complex locking ring structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The locking ring is completely removed from the design. Instead, connection elements are directly attached to the vessel portions and work in conjunction with actuators to create the clamping force. This extraction eliminates the complexity of the locking ring while maintaining the essential function of interconnecting the vessel portions.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If a locking ring is used to ensure gas-tight connection, then reliability is improved, but manufacturing precision requirements increase

Engineering Contradiction:
Improvegas-tight connectionVSAvoidprecision
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The connection is segmented into multiple discrete connection elements distributed around the circumference. This segmentation allows each element to independently achieve proper alignment and sealing, reducing the cumulative precision requirements compared to a single locking ring that must maintain uniform precision around the entire circumference.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each connection element is designed with localized sealing features (such as gaskets or sealing surfaces) that ensure gas-tight connection at each specific location. This local approach to sealing is more forgiving of manufacturing variations than a continuous locking ring that requires uniform precision throughout.

Inventive Principle:
Principle #3Local quality

3Strength

If a locking ring is used to withstand detonation loads, then strength is improved, but manufacturing cost increases

Engineering Contradiction:
Improvedetonation resistanceVSAvoidmanufacturing cost
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The strength requirement is segmented across multiple connection elements rather than concentrated in a single locking ring. Each connection element can be designed and manufactured independently using standard, cost-effective components, while the collective arrangement provides the necessary strength to withstand detonation loads.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The expensive and complex locking ring is removed and replaced with simpler, more manufacturable connection elements. These elements can be produced using conventional manufacturing processes, significantly reducing manufacturing cost while maintaining the required strength through proper design and material selection.

Inventive Principle:
Principle #2Taking out (Extraction)

4Force

If a locking ring is used to clamp vessel portions, then clamping force is improved, but ease of operation decreases

Engineering Contradiction:
Improveclamping forceVSAvoidoperation simplicity
Core Design Contradiction:
ForceVSEase of operation

Solution Approach 1:

The manual mechanical operation of installing and removing a locking ring is replaced with automated or semi-automated actuators that apply clamping force to the connection elements. This substitution maintains or enhances the clamping force while dramatically improving ease of operation, as the actuators can be controlled through simple interfaces or automated sequences.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
