Alginate Capsule Packaging with Dual-Liquid Cushioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Food capsules coated with an alginate film often break during transport or handling, leading to product loss and quality issues due to their fragile nature.
Innovation Solution
A packaging method involving a container with a first liquid surrounding the capsules and a second liquid with a lower density layered above, providing cushioning and preventing breakage, with the second liquid having a thickness of at least 0.5 cm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If capsules are packaged in a container with first liquid only, then the packaging structure is simple, but capsule breakage occurs during transport
Solution Approach 1:
The patent introduces a second liquid layer with lower density than the first liquid, positioned above the capsules in the container. This second liquid acts as a cushioning layer that absorbs impact forces during transport, preventing capsule breakage before damage can occur. The layer thickness is maintained at至少 0.5 cm to ensure adequate protection.
Solution Approach 2:
The second liquid serves as an intermediary substance between the capsules and the container lid, as well as between capsules during stacking. This intermediary layer distributes and reduces mechanical stresses transmitted to the fragile capsules, resolving the contradiction between simple packaging and capsule protection.
2Ease of operation
If alginate film is made sufficiently fragile to break in mouth, then consumption experience is improved, but capsules break during transport
Solution Approach 1:
The second liquid layer provides beforehand cushioning that protects the fragile alginate film capsules during transport. By absorbing impact forces before they reach the capsules, the cushioning layer allows the film to remain sufficiently fragile for mouth-breaking while preventing premature breakage during handling and transport.
Solution Approach 2:
The patent changes the physical parameters of the packaging environment by introducing a second liquid layer with specific density and thickness characteristics. This parameter change creates a protective environment that compensates for the inherent fragility of the alginate film, allowing it to maintain both its mouth-breaking property and transport durability.
3Loss of substance
If capsule breakage occurs during transport, then product loss increases, but adding protection increases packaging complexity
Solution Approach 1:
The second liquid layer serves as a beforehand cushioning mechanism that prevents capsule breakage and subsequent product loss. By absorbing impact forces during transport, this simple liquid layer reduction in product loss without requiring complex protective structures or additional packaging materials.
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 method effectively prevents capsule breakage during transport and handling, maintaining product quality by ensuring the capsules remain intact with a damage percentage of 0% when the oil layer thickness is at least 0.5 cm.
Implementation Method 1
adding a second liquid with a density lower than that of the first liquid so that the layer of the second liquid in the container has a thickness of at least 0.5 cm
Implementation Method 2
said second liquid is situated in the upper part of the container, cushioning the contact between the capsules and the lid of the can in which they are packaged
