Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing garbage bags are complex and expensive to manufacture, and they often fail to effectively absorb liquids and odors, leading to contamination and unpleasant vapors when damaged or filled with damp contents.
Innovation Solution
A garbage bag design featuring a liquid-absorbing strip made of materials that can be welded to the side walls, integrated into the weld seams, allowing it to hang down and absorb liquids, with the option of incorporating superabsorbent materials for enhanced capacity and odor control, produced using a continuous process that simplifies and reduces production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a liquid-absorbing layer is integrated into the bag body using complex methods (gluing, hot-gluing, multi-layer construction), then liquid absorption capacity is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The liquid-absorbing strip is merged with the side walls through welding, combining two separate functions (liquid absorption and structural integrity) into a single integrated component. This eliminates the need for separate gluing or hot-gluing processes, reducing manufacturing complexity while maintaining liquid absorption capacity.
Solution Approach 2:
The invention changes the manufacturing approach from chemical bonding (gluing, hot-gluing) to thermal bonding (welding). This parameter change in the bonding method simplifies the manufacturing process and reduces costs while achieving the same liquid absorption function.
2Quantity of substance
If a liquid-absorbing layer is applied to the inside of the bag body using multiple layers and adhesives, then liquid absorption is improved, but production cost increases
Solution Approach 1:
The liquid-absorbing function is extracted from the complex multi-layer construction and isolated into a separate strip component. This strip can be independently manufactured and then integrated into the bag body through welding, reducing production costs while maintaining liquid absorption capacity.
Solution Approach 2:
The liquid-absorbing strip is merged with the side walls through welding, combining two separate functions (liquid absorption and structural integrity) into a single integrated component. This eliminates the need for separate gluing or hot-gluing processes, reducing manufacturing complexity while maintaining liquid absorption capacity.
3Stability of the object's composition
If the liquid-absorbing strip is fixed at the bottom of the bag body, then it remains in position, but it cannot effectively hang down to absorb liquids at the floor level
Solution Approach 1:
The liquid-absorbing strip is welded into the side seams at a distance from the floor, allowing it to hang down excessively beyond the bag body's main structure. This partial fixation combined with excessive hanging length enables the strip to reach the floor level effectively, absorbing liquids that would otherwise escape.
4Reliability
If existing garbage bags are designed with integrated liquid absorbers using complex construction, then liquid containment is improved, but the bags become less recyclable and more expensive
Solution Approach 1:
The liquid-absorbing strip is merged with the side walls through welding, combining two separate functions (liquid absorption and structural integrity) into a single integrated component. This eliminates the need for separate gluing or hot-gluing processes, reducing manufacturing complexity while maintaining liquid absorption capacity.
Solution Approach 2:
The invention changes the bonding method from chemical bonding (gluing, hot-gluing) to thermal bonding (welding). This parameter change in the bonding method simplifies the manufacturing process and reduces costs while achieving the same liquid absorption function.

Function Achieved in This Case
The solution effectively absorbs liquids and reduces odor release, preventing contamination and simplifying production while maintaining the bag's integrity and recyclability, making it a cost-effective and efficient option for domestic and commercial use.
Implementation Method 1
the liquid-absorbing strip consists entirely or partially of a material that can be welded to the side walls
Implementation Method 2
a liquid-absorbing strip being arranged between the side walls... the liquid-absorbing strip is fixed only at the two welds and is welded into the lateral welds

AI summary
The garbage bag is provided with two side walls (2,3) and an opening (15) limiting an upper edge, where other edges are connected by welding seams (6,7). The lower edge is connected by a bottom (16). A liquid absorbent strip (17) is provided between the side walls. The liquid absorbent strip consists of polyethylene, polypropylene, nonwoven polyethylene fibers or polypropylene fibers.
