Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If direct heating device is used to melt and mount fluororesin tubes, then heating process is simplified, but uneven heating occurs causing false welding and extended process time
Solution Approach 1:
A vacuum chamber serves as an intermediary environment that enables uniform thermal distribution throughout the fluororesin tube bundle. The vacuum atmosphere eliminates heat loss through convection and allows consistent thermal energy transfer from the heating source to all tube surfaces, resolving the uneven heating problem while maintaining process simplicity
Solution Approach 2:
The invention changes the thermal parameters by controlling temperature distribution uniformly across all fluororesin tubes through the vacuum environment. By maintaining consistent temperature parameters throughout the bundle rather than localized heating, the method achieves uniform melting and mounting without false welding
2Device complexity
If direct heating device is used, then equipment complexity is reduced, but processing time is extended due to uneven heating
Solution Approach 1:
The vacuum chamber acts as a time-efficient intermediary that accelerates the heating process by eliminating thermal losses. This allows rapid and uniform heating of the entire fluororesin tube bundle simultaneously, significantly reducing processing time compared to conventional direct heating methods while adding minimal equipment complexity
Solution Approach 2:
The vacuum heating method enables continuous and simultaneous heating of all fluororesin tubes throughout the bundle. The thermal energy acts continuously on all surfaces without interruption or repositioning, eliminating the time loss associated with uneven heating and multiple heating cycles
3Reliability
If uneven heating occurs, then some tubes are properly mounted, but false welding occurs on other spots increasing safety risks
Solution Approach 1:
By changing the thermal environment to a vacuum state, the invention achieves uniform temperature distribution across all fluororesin tubes. This parameter change ensures that melting and mounting occur uniformly throughout the bundle, eliminating false welding spots and the associated safety risks of chemical leakage
Solution Approach 2:
The vacuum chamber creates an inert environment that prevents oxidation and contamination during the heating and mounting process. This controlled atmosphere ensures consistent thermal properties throughout the bundle, preventing localized false welding and enhancing the overall reliability and safety of the fluororesin tube assembly

AI summary
The present invention reveals a manufacturing method of a fluororesin bundle having a plurality of fluororesin tube hold by a fixing element as a bundle. The bundle is pre-sealed when the ends of the fluororesin tubes are heated to a status being deformable and mount on the fixing element while being place in a vacuum environment and receive a thermal energy. Immersing the pre-sealed bundle into a heating pool to extend the mounted surface between the fluororesin tubes and the fixing element. Thus, a high quality fluororesin bundle can be done by using the above processes.
