Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for preparing cooked tapioca pearls are inconvenient, time-consuming, and pose safety risks due to potential bag explosions during microwave heating, while manual filling leads to inconsistent filling amounts and sanitary issues.
Innovation Solution
A method involving automated production of a cooked tapioca pearl bag using a filling bag film and breathable bag film, with vent holes and a breathable zone, to create an explosion-proof and breathable package through a series of bag-making, filling, and sealing processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a plastic bag is used to contain cooked tapioca pearls for microwave heating, then heating convenience is improved, but the bag may explode due to steam pressure
Solution Approach 1:
The breathable bag film incorporates multiple vent holes distributed across its surface, allowing steam to escape during microwave heating while maintaining the convenience of microwaveable packaging. This porous structure resolves the contradiction by enabling pressure relief without compromising ease of operation.
Solution Approach 2:
The bag structure is divided into a filling bag film and a breathable bag film with distinct functions. The breathable bag film with vent holes handles steam venting, while the filling bag film contains the product. This segmentation allows each component to specialize, preventing explosion while maintaining heating convenience.
2Adaptability or versatility
If manual labor is used to fill plastic bags with cooked tapioca pearls, then flexibility is improved, but filling speed is slow and filling amount cannot be kept constant
Solution Approach 1:
The automated filling system uses the breathable bag film's unique properties to enable self-regulating filling. The vent holes allow the system to automatically control filling amount through pressure equalization, eliminating the need for manual adjustment while maintaining consistency and speed.
Solution Approach 2:
The breathable bag film serves multiple functions: it contains the product, allows steam venting during heating, and enables automated filling control. This multi-functionality replaces manual filling operations while maintaining the flexibility needed for consistent filling amounts at high speed.
3Strength
If heat pressing is used to seal the plastic bag, then sealing strength is improved, but the filling speed remains slow
Solution Approach 1:
The breathable bag film is pre-formed with vent holes and adhesive sections before filling. This preliminary preparation allows the heat pressing operation to focus only on sealing rather than creating the entire structure, thereby maintaining strong seals while increasing overall filling speed.
4Productivity
If automated bag making machine is used, then filling speed and consistency are improved, but device complexity increases
Solution Approach 1:
The invention uses flexible breathable bag film that can be easily manipulated by simple mechanical means. The thin film structure with pre-formed vent holes allows automated handling without requiring complex machinery, thereby achieving high filling speed with relatively simple device design.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The method ensures consistent filling, reduces fabrication costs, prevents explosions, and maintains sanitary standards by providing an automated, explosion-proof, and breathable tapioca pearl bag.
Implementation Method 1
the temperature in the plastic bag is increased rapidly during the heating process, and the steam will produce a great pressure that easily causes explosion of the plastic bag
Implementation Method 2
adhering an end edge of the filling bag film with an end edge of the breathable bag film and adhering a top and two sides of the end edge of the breathable bag film simultaneously

AI summary
A method for making a cooked tapioca pearl bag includes placing a filling bag film and a breathable bag film on a bag making machine so that the filling bag film overlaps the breathable bag film, combining the filling bag film and the breathable bag film to form a tapioca pearl bag film, folding the tapioca pearl bag film, adhering two sides of the tapioca pearl bag film so that the tapioca pearl bag film has a strip shape with a hollow interior, adhering and cutting the bottom of the tapioca pearl bag film, filling cooked tapioca pearl and syrup into the tapioca pearl bag film, and adhering and cutting the top of the tapioca pearl bag film to form a final product of a cooked tapioca pearl bag.
