Vacuum Bag Outer Packing Unit for Shape Regularity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum bags are soft and irregular in shape, making them difficult to stack and store, prone to damage, and have a short lifespan due to susceptibility to scratches and hard objects.
Innovation Solution
A vacuum packing bag design featuring an outer packing unit with a buckle device, including a buckled belt to secure the vacuum bag, and a supporting board to maintain a regular shape and protect the bag, along with a handle for convenience and easy disassembly for storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the vacuum bag is made of soft material (PVC or nylon composite film), then it is flexible and easy to seal, but it cannot maintain a regular shape after items are packed, making it difficult to stack and store
Solution Approach 1:
The invention divides the vacuum bag system into two separate components: a soft inner vacuum bag for sealing and protection, and a rigid outer packing unit for shape maintenance and stacking. The inner bag can be easily sealed while the outer unit provides the regular shape, resolving the contradiction between ease of sealing and shape maintenance.
2Weight of moving object
If the vacuum bag is made of soft material, then it is lightweight and flexible, but it is easily scratched and damaged by sharp and hard objects, shortening its lifespan
Solution Approach 1:
The soft inner vacuum bag is nested inside the rigid outer packing unit. The inner bag maintains light weight and flexibility for sealing, while the outer unit provides protection against scratches and hard objects. This nested structure allows both components to fulfill their respective functions without compromising each other.
3Ease of operation
If the vacuum bag is made of soft material, then it is comfortable to handle, but it cannot be stacked nicely in wardrobe or other storing spaces
Solution Approach 1:
By separating the vacuum bag into an inner soft bag and an outer rigid unit, the inner bag remains easy to handle for packing items, while the outer unit provides the regular shape needed for neat stacking in wardrobes and storage spaces.
4Ease of manufacture
If the vacuum bag is made of soft material, then it is easy to manufacture, but the shape cannot be irregular after clothes or bed quilt are put in
Solution Approach 1:
The manufacturing of the inner soft vacuum bag remains simple and easy, while the outer rigid packing unit is separately manufactured with the desired regular shape. This segmentation allows each component to be optimized independently - the inner bag for ease of manufacture and the outer unit for shape regularity.
