Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing odor control methods in garbage bags, such as activated carbon patches and fragrances, are inefficient, costly, and can lead to bacterial growth or environmental hazards, while powders accumulate at the bottom, limiting odor adsorption and causing manufacturing issues.
Innovation Solution
A garbage bag with a strip-shaped carrier containing an odor-controlling substance applied to a large surface area, allowing for efficient odor reduction by ensuring contact between odor molecules and the active ingredient, and using a thermoplastic material for easy integration into the bag during manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If activated carbon patches are used for odor adsorption, then odor control is achieved, but the material cost increases and the surface area for adsorption is limited
Solution Approach 1:
The bag is divided into multiple zones with different carrier configurations: a first carrier in the upper region and a second carrier in the lower region. This segmentation allows optimized placement of odor-controlling substances in different areas, improving overall odor control while managing material costs effectively.
Solution Approach 2:
The carrier is designed with a three-dimensional structure including upper and lower regions at different heights within the bag. This vertical dimensionality increases the effective surface area for odor adsorption compared to traditional single-layer patches, enhancing odor control effectiveness without proportionally increasing material cost.
2Object-affected harmful factors
If fragrances are applied to mask odors, then existing odors are masked, but new unpleasant smells can develop and allergenic potential increases
Solution Approach 1:
Instead of using fragrances that mask odors (which can create new unpleasant smells and allergens), the invention uses odor-neutralizing substances that chemically convert harmful odor molecules into benign substances. This transforms the approach from masking harmful odors to actively neutralizing them, eliminating the side effects of fragrance application.
Solution Approach 2:
The invention changes the chemical parameter of the odor-controlling substance from fragrance compounds to odor-neutralizing agents. This parameter change fundamentally alters the mechanism from masking to chemical neutralization, eliminating allergenic potential and preventing new unpleasant smells while maintaining odor control effectiveness.
3Reliability
If odor-controlling substances are applied as powders, then chemical odor neutralization is achieved, but powders collect at the bottom of the bag preventing odor molecules from contacting the active substance
Solution Approach 1:
The carrier is segmented into upper and lower regions, with the first carrier positioned in the upper region and the second carrier in the lower region. This segmentation ensures that odor-neutralizing substances are distributed throughout the bag volume, preventing powder accumulation at the bottom and ensuring continuous contact with rising odor molecules.
Solution Approach 2:
The invention transitions from a single-layer powder application to a three-dimensional carrier structure with vertical distribution. The carrier extends through different heights within the bag, creating multiple contact zones for odor molecules at various stages of their rise, thereby maintaining accessibility and neutralization effectiveness throughout the bag volume.
4Ease of manufacture
If aqueous solutions are used for fragrance application, then easy application is achieved, but liquid remains in the bag promoting bacterial growth
Solution Approach 1:
The invention changes the physical state parameter of the odor-controlling substance from liquid (aqueous solution) to solid form incorporated in the carrier. This parameter change eliminates the bacterial growth problem associated with liquid residue while maintaining ease of manufacture through simple carrier integration during bag production.
5Object-generated harmful factors
If volatile solvents are used for fragrance application, then complete evaporation is achieved, but occupational safety and explosion protection measures are required during manufacturing
Solution Approach 1:
The invention changes the volatility parameter of the odor-controlling substance from high (volatile solvents) to negligible (solid substances in carrier). This parameter change eliminates the need for occupational safety and explosion protection measures during manufacturing while still achieving complete elimination of residue, as the solid substance remains stable and does not evaporate.
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
The solution provides effective odor control with reduced material costs and manufacturing complexity, ensuring even distribution of the odor-controlling substance and preventing bacterial growth, while maintaining a high active surface area for odor reduction.
Implementation Method 1
The binding of odor molecules by adsorption to active surfaces can be further restricted by the fact that other substances, which do not contribute to the odor, also bind to the surface and reduce the adsorption capacity.
Implementation Method 2
the application of odor-controlling substances is known; these substances react chemically with odor molecules and convert them into less odorous or odorless substances
