Resin Garbage Bag with Integrated Odorant Repellent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional repellents are unsatisfactory in both effectiveness and cost, and existing methods for manufacturing shaped articles with repellent properties using synthetic resin compositions have not been practiced, leading to issues such as garbage bags being ripped by animals and cable insulation being damaged by rodents, resulting in waste and potential electrical hazards.
Innovation Solution
A synthetic resin composition incorporating 10 to 15,000 ppm of salicylic acid esters, menthol, or camphor, which can be shaped into articles like garbage bags and cable insulation, utilizing thermoplastic polymers and optional elastomers or fillers to prolong the repellent effect, preventing animal interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional repellents are used (impregnated into powdery support or sprayed directly), then repellent effect is achieved, but cost and satisfaction are unsatisfactory
Solution Approach 1:
The patent merges the repellent function with the structural material by incorporating repellent compounds directly into the synthetic resin composition during manufacturing. This combines the bag material and repellent into a single integrated product, eliminating separate application steps and reducing costs.
Solution Approach 2:
The repellent compounds are incorporated into the synthetic resin composition before the shaping process. This preliminary incorporation ensures the repellent effect is built-in from the start, eliminating the need for subsequent spraying or impregnation steps.
2Duration of action of stationary object
If high concentration of odorants is used to achieve sufficient repellent effect, then durability improves, but unwanted bleeding occurs above 15,000 ppm
Solution Approach 1:
The patent optimizes the concentration parameter of odorants within the specific range of 10-15,000 ppm. This parameter optimization ensures sufficient repellent effect while preventing unwanted bleeding that occurs at higher concentrations.
3Reliability
If repellent compounds are incorporated into synthetic resin before shaping, then shaped articles with repellent effect are produced, but manufacturing process complexity increases
Solution Approach 1:
The patent combines multiple functions (structural material and repellent) into a single synthetic resin composition, allowing both the bag structure and repellent effect to be produced in one manufacturing process rather than requiring separate steps.
Solution Approach 2:
The synthetic resin composition serves multiple functions: it provides the structural integrity of the garbage bag and simultaneously delivers the repellent effect. This multi-functionality simplifies the overall manufacturing process.
4Productivity
If conventional disposal method is used (garbage bags placed outside), then garbage collection is efficient, but animals rip bags causing scattering and waste
Solution Approach 1:
The patent applies preliminary anti-action by incorporating repellent compounds into the garbage bag material before use. This pre-applied repellent effect deters animals from approaching or damaging the bags, preventing the harmful action before it can occur.
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 composition effectively repels domesticated animals and varmints by incorporating odorants into the resin before shaping, providing a durable and long-lasting repellent effect that prevents damage to articles while being non-unpleasant for humans, with optimal concentrations between 1,000 to 14,000 ppm for best results.
Implementation Method 1
The inventor has discovered that animals, including cats, dogs, rats and crows, dislike the particular odor of salicylic acid esters, menthol and camphor. The invention uses this characteristic of salicylic acid esters, menthol and camphor to provide shaped articles with a repellent effect by incorporating the odorants into the synthetic resin prior to forming the shaped articles.
Data Source
AI summary
An article, such as a container or bag for garbage, which repels animals such as cats, dogs, rats, and crows. The article may be made from a synthetic resin composition including a synthetic resin and from 10 to 15,000 ppm by weight of a salicylic acid ester, menthol and/or camphor. The article may also be made from a synthetic resin composition including a synthetic resin and an odorant composition containing eucalyptus oil and one or more of a salicylic acid ester, menthol and camphor.
