Upright Bottle Bottom Cooling via Diagonal Nozzle Injection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing carbonated drink filling methods require complex manufacturing line structures and increased equipment costs due to the need to invert and reorient bottles for cooling and filling, which can lead to deformation and instability, especially in bottles with thick bottoms.
Innovation Solution
A method where the bottle is kept upright throughout the process, with a sterilization device and coolant injection nozzles positioned to cool the bottle's bottom before and after sterilization, preventing deformation by injecting coolant from nozzles on either side of the conveyance line, directed diagonally upward to intersect with the bottle's path, ensuring efficient cooling and minimizing liquid droplet entry into the bottle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the bottle is inverted and water is injected for cooling and washing, then the bottom of the bottle can be quickly cooled, but the manufacturing line structure becomes complex and equipment cost increases
Solution Approach 1:
Instead of inverting the bottle to inject cooling water from below, the patent applies cooling nozzles directed diagonally upward from the sides of the conveyance line. This inverted approach achieves bottom cooling without requiring bottle inversion, thereby simplifying the manufacturing line structure while maintaining cooling effectiveness
2Device complexity
If the bottle is kept upright throughout the process, then the manufacturing line structure is simplified, but the bottom of the bottle may deform due to slow heat removal
Solution Approach 1:
The patent applies cooling nozzles positioned to direct coolant diagonally upward at the bottom area of the bottle. This localized cooling approach concentrates thermal energy removal at the bottom region, ensuring rapid heat removal and preventing deformation while keeping the bottle upright throughout the process
3Object-affected harmful factors
If coolant is injected from nozzles on either side of the conveyance line, then liquid droplets are less likely to enter the bottle, but the cooling coverage area increases
Solution Approach 1:
The patent positions cooling nozzles asymmetrically on either side of the conveyance line with diagonal upward orientation. This asymmetric arrangement creates a cooling pattern that directs coolant away from the bottle opening while maintaining effective bottom cooling coverage, thereby reducing contamination risk without sacrificing cooling efficiency

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach simplifies the manufacturing line, prevents buckling and deformation of bottle bottoms, maintains bottle stability, and reduces contamination risks by keeping the bottle upright during filling, ensuring a stable and clean filling process.
