Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the heat shrink tube is not properly cooled in a transmission channel, then the temperature inside the heat shrinkable machine is maintained, but the heat shrink tube cannot be cooled efficiently and heat is lost
Solution Approach 1:
The transmission channel is divided into a heating area and a cooling area that are spatially separated. The air guiding member creates distinct zones: one for heating the heat shrink tube and another for cooling it after processing. This segmentation allows independent temperature control in each zone, maintaining heating effectiveness while enabling efficient cooling without mixing hot and cold air flows.
Solution Approach 2:
The cooling function is extracted from the heating process by introducing a separate cooling area with dedicated air blowing members. Instead of attempting to cool the entire transmission channel, the invention extracts only the necessary cooling function into a specific zone downstream, allowing the heating area to maintain its temperature independently while providing targeted cooling where needed.
2Temperature
If cooling airflow is allowed to flow freely, then cooling efficiency is improved, but heat diffuses to the heating area reducing energy efficiency
Solution Approach 1:
The air guiding member provides localized air flow control with different properties in different areas. Air blocking plates are positioned to restrict cooling airflow specifically at the boundary between heating and cooling areas, while air deflecting plates guide the cooling airflow along the transmission channel. This local quality control ensures strong cooling where needed while preventing heat diffusion to the heating area.
Solution Approach 2:
The air guiding member acts as an intermediary structure between the heating and cooling areas. It includes air blocking plates that prevent direct mixing of hot and cold air flows, and air deflecting plates that mediate the cooling airflow path. This intermediary structure allows the cooling airflow to be effective in the cooling area while blocking its direct path to the heating area, thus preventing heat diffusion.
3Productivity
If cables are piled or stacked immediately after heat shrinking, then productivity is improved, but adhesion occurs affecting product quality
Solution Approach 1:
The cooling action is performed preliminarily in the cooling area before the cables are stacked for storage or further processing. By providing a dedicated cooling zone with controlled airflow that directs cooling air along the cables and blocks it from rising to the heating area, the cables are pre-cooled and solidified before stacking. This preliminary cooling prevents adhesion during subsequent stacking operations, allowing high productivity without compromising surface quality.

AI summary
An air-cooling mechanism includes an air guiding member and an air blowing member spaced from the air guiding member. An air-cooling area is formed between the air guiding member and the air blowing member. The air-cooling area has an air inlet and an air outlet. The air blowing member blows air towards the air guiding member to form a cooling airflow. The air guiding member includes air blocking plates and air deflecting plates connected to the air blocking plates and extending into the air-cooling area. The air blocking plates block the cooling airflow from flowing out of the air-cooling area, and an air outlet gap is formed between adjacent air blocking plates. The air deflecting plates block the cooling airflow in the air-cooling area from flowing towards the heating area and guide the cooling airflow towards the air outlet gap.
