High-Pressure Pipe Protector Element for Sealing Surface Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-pressure fluid systems, such as those in large internal combustion engines, face challenges with sealing surface damage during transportation and assembly due to external impacts, and the need for periodic disconnection of high-pressure pipes for servicing, which can lead to leakage and safety issues.
Innovation Solution
A pipe assembly with a protector element featuring a spring portion that covers and protects the sealing surface, allowing connection without removing the protector, and a sleeve that transmits clamping force to secure the sealing surface against adjacent components, maintaining protection during assembly and disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the sealing surface is exposed for connection, then the connection operation is simplified, but the sealing surface is damaged by external impacts
Solution Approach 1:
The sealing surface is pre-covered with a protective cap before transportation and assembly. This preliminary protective action ensures the sealing surface is already protected when the component arrives at the assembly location, eliminating the need to remove protection during connection operations.
Solution Approach 2:
A protective cap serves as an intermediary element between the sealing surface and external environment. This cap absorbs external impacts and prevents direct contact between harmful factors and the sealing surface, while allowing the connection operation to proceed by simply removing the cap.
2Ease of operation
If the protector element is removed for connection, then the connection is simplified, but the sealing surface is exposed to damage
Solution Approach 1:
The protective cap acts as a removable intermediary that can be easily taken off for connection operations. After connection is complete, the cap can be replaced to restore protection, thus maintaining sealing surface integrity without complicating the connection process.
Solution Approach 2:
The protective cap is temporarily discarded (removed) during the connection operation and then recovered (reinstalled) afterward. This approach allows the connection to proceed with full access to the sealing surface while ensuring protection is restored immediately after connection to prevent future damage.
3Reliability
If the sealing surface is protected during transportation, then the sealing surface integrity is maintained, but the connection process becomes more complex
Solution Approach 1:
The protective cap is pre-installed on the sealing surface before the component enters the assembly process. This preliminary protection eliminates the need for complex protective measures during connection, as the cap simply needs to be removed and replaced - a straightforward operation that doesn't add complexity to the connection process itself.
