Flexible Kimchi Container with Rigid Base and Pressing Plates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional kimchi packaging containers are prone to damage from external impacts, shape deformation, and freezing issues during storage, leading to quality deterioration and difficulties in storage and transportation.
Innovation Solution
A kimchi packaging container with a flexible pouch design featuring a support part with a fixed shape to protect the lower end, a cover part with pressing plates to maintain pressure on the kimchi, and a handle strap for easy handling, ensuring the shape is maintained and pressure is consistently applied.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the pouch is made of flexible material, then the packaging is easy to manufacture and store, but the lower end is easily damaged by external impact
Solution Approach 1:
The patent uses a composite structure combining a flexible pouch (accommodation part) made of flexible material with a rigid support part made of rigid material. The rigid support part is coupled to the lower end of the flexible pouch, providing impact resistance while the flexible pouch maintains ease of manufacture and storage. This composite structure resolves the contradiction by combining materials with different properties to achieve both flexibility and strength.
2Ease of manufacture
If the pouch is made of flexible material, then the packaging can be easily formed, but the shape cannot be maintained and stacking is difficult
Solution Approach 1:
The packaging container is divided into two functional segments: the accommodation part (pouch) made of flexible material that is easy to form, and the support part made of rigid material that maintains the shape. The support part is coupled to the lower end of the pouch, allowing the flexible portion to be easily manufactured while the rigid portion provides shape stability for stacking and storage.
3Temperature
If the lower end of the pouch is in contact with the refrigerator wall, then refrigeration is effective, but the kimchi is easily frozen and quality deteriorates
Solution Approach 1:
The rigid support part acts as an intermediary between the flexible pouch and the refrigerator wall. It provides thermal insulation, preventing direct contact between the kimchi in the pouch and the cold refrigerator surface, thereby avoiding excessive freezing while still allowing effective refrigeration. This mediator structure resolves the contradiction by controlling the thermal interaction.
4Device complexity
If the connection part is positioned lower than the pressing plates, then the structure is simple, but kimchi cannot be pressed when storage amount is reduced
Solution Approach 1:
The pressing plates are designed to be movable rather than fixed, allowing them to dynamically adjust their position based on the storage amount of kimchi. When kimchi is consumed and the storage amount decreases, the pressing plates can move downward to maintain contact and continue pressing the remaining kimchi. This dynamic design maintains pressing function reliability without significantly increasing structural complexity.
