Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional large-sized packaging bags are inconvenient to carry or move due to their size and weight, posing challenges in daily use and handling.
Innovation Solution
A packaging bag design featuring a portable portion on its side, which includes a sealing patch and a portable patch, manufactured using an apparatus comprising traction, punching, clamping, point-ironing, ironing, and cooling devices to create a handle structure that facilitates easy carrying and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If large-sized packaging bags are used to accommodate heavier goods, then the packaging capacity and load-bearing capability are improved, but the ease of carrying and moving deteriorates
Solution Approach 1:
The packaging bag is segmented into a main body and a separate portable portion (handle). The handle is formed by punching holes in the film material and sealing patches that cover these holes, creating a distinct carrying component separate from the main packaging body. This allows the bag to maintain large size for capacity while providing a dedicated structure for easy carrying.
2Ease of operation
If a portable portion is added to the packaging bag, then the ease of carrying is improved, but the device complexity increases
Solution Approach 1:
The portable portion is merged with the main body through sealing patches that are thermally bonded to the film material. The handle structure, punching holes, and sealing patches are integrated into a single cohesive component that becomes part of the packaging bag itself, rather than being a separate attachment. This reduces overall structural complexity while maintaining carrying functionality.
