Dough Package Microvents Prevent Internal Pressure Buildup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packaging methods for pre-proofed dough products often result in pressurized containers that can pop when opened, and existing solutions with pressure release valves are prone to fouling and are expensive.
Innovation Solution
The use of microvents in dough packages, which allow gases like carbon dioxide to be expelled during dough expansion, reducing internal pressure and preventing further gas passage, thus eliminating the need for pressure release valves and minimizing the risk of container popping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed volume package is used for pre-proofed dough, then the dough can proof inside the package, but the internal pressure increases and may cause the container to pop
Solution Approach 1:
The package is segmented into multiple microvents distributed across the package surface, allowing pressure to be released at multiple locations rather than a single point, preventing container popping while maintaining proofing convenience
Solution Approach 2:
The package incorporates microvents that create a porous structure in the packaging material, allowing gas to pass through the package walls during proofing, thereby maintaining internal pressure at safe levels while enabling complete proofing inside the package
2Stress or pressure
If a pressure release valve is used to vent gas, then internal pressure is reduced, but the valve is prone to fouling and increases cost
Solution Approach 1:
Instead of a single pressure release valve, the system uses multiple microvents distributed across the package, eliminating the fouling problem associated with single-point valves while maintaining effective pressure control throughout the package
Solution Approach 2:
The problematic pressure release valve component is completely removed from the system. The microvents are integrated directly into the package structure, eliminating the need for separate valve mechanisms that are prone to fouling and increase cost
3Object-generated harmful factors
If a pressure release valve is used, then gas can be vented, but the device complexity and cost increase
Solution Approach 1:
The gas venting function is merged directly into the package structure through microvents, eliminating the need for separate pressure release valve components and reducing overall device complexity while maintaining effective gas venting capability
Solution Approach 2:
The package structure is modified to include microvents that provide gas venting as an inherent property of the packaging material itself, rather than requiring additional mechanical valve components, thereby simplifying the overall device
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
This approach allows dough to expand and fill the package volume without excessive pressure buildup, maintaining a low internal pressure and preventing container popping, while also reducing the risk of contamination and handling issues associated with external proofing.
Implementation Method 1
allowing a contained dough composition to proof and expand inside of the packaging... upon further expansion will increase the pressure inside the canister
