Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional expansion and contraction methods are used to install tube plugs, then the installation process becomes complex and time-consuming, but the tube plug can be installed

Engineering Contradiction:
Improveinstallation speedVSAvoidinstallation process complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The tube plug is pre-assembled with the expansion band in the correct configuration before insertion into the tube. This preliminary preparation eliminates the need for complex on-site assembly and expansion operations, allowing for quick insertion and immediate functionality.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The expansion and contraction operations are extracted from the installation process by using a pre-assembled plug that requires no field expansion. The plug is simply inserted into the tube opening and secured, removing the time-consuming expansion step entirely.

Inventive Principle:
Principle #2Taking out (Extraction)

2Loss of time

If conventional expansion and contraction methods are used to install tube plugs, then the installation time increases, but the tube plug can be installed

Engineering Contradiction:
Improveinstallation timeVSAvoidinstallation ease
Core Design Contradiction:
Loss of timeVSEase of operation

Solution Approach 1:

The tube plug is pre-assembled with the expansion band in the correct configuration before insertion into the tube. This preliminary preparation eliminates the need for complex on-site assembly and expansion operations, allowing for quick insertion and immediate functionality.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The expansion and contraction operations are extracted from the installation process by using a pre-assembled plug that requires no field expansion. The plug is simply inserted into the tube opening and secured, removing the time-consuming expansion step entirely.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If tube plugs are not properly installed, then tube leakage occurs affecting heat exchanger performance, but proper installation requires complex procedures

Engineering Contradiction:
Improveheat exchanger performanceVSAvoidinstallation procedure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The tube plug is pre-assembled with the expansion band in the correct configuration before insertion into the tube. This preliminary preparation eliminates the need for complex on-site assembly and expansion operations, allowing for quick insertion and immediate functionality.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The expansion band acts as an intermediary component that provides a simple mechanical interference fit between the tube plug and tube opening. This intermediary mechanism ensures reliable sealing and structural integrity without requiring complex installation procedures.

Inventive Principle:
Principle #24Intermediary (Mediator)
