Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plastic container production machines require external cooling units and complex refrigeration systems for cooling forming components, which complicates the manufacturing process and increases costs.
Innovation Solution
Utilize the liquid being filled into plastic containers as a cooling medium to cool forming device components, such as blow molds, through a heat exchanger device that integrates with the product flow, ensuring efficient and integrated cooling without additional external cooling units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If external cooling units and refrigeration systems are used to cool forming components, then the forming components can be cooled effectively, but the device complexity and manufacturing costs increase
Solution Approach 1:
The liquid supply line serves dual functions: transporting the liquid product to be filled and cooling the forming components simultaneously. This multi-functional use of the supply line eliminates the need for separate cooling systems, reducing device complexity while maintaining effective cooling of blow molds and other forming components
Solution Approach 2:
The liquid product itself is used as the cooling medium for the forming components. The system serves its own cooling needs through the product flow, eliminating dependency on external cooling units and refrigeration systems, thereby simplifying the overall device structure
2Temperature
If external cooling units are delivered with each machine, then cooling can be provided, but the manufacturing cost and device complexity increase
Solution Approach 1:
The liquid supply line is designed to perform both product transport and cooling functions. This eliminates the need to manufacture and deliver separate cooling units with each machine, reducing manufacturing costs while ensuring adequate cooling capability through the integrated product flow system
3Temperature
If cooling piping and refrigeration systems are installed by the customer, then cooling can be achieved, but the device complexity and installation complexity increase
Solution Approach 1:
The forming device uses its own liquid supply system to provide cooling, eliminating the need for customer-installed cooling piping and refrigeration systems. The product flow itself performs the cooling function, greatly simplifying the cooling system structure and reducing installation complexity
