Solution Overview
Problem
Existing toilet roll deodorizing techniques face issues such as limited deodorant coverage, excessive fragrant agent usage, insufficient odor masking, delayed deodorizing effects, and difficulty in recognizing the effectiveness of applied deodorants in toilet spaces.
Innovation Solution
A toilet roll design featuring belt-shaped toilet paper wound around a paper tube, where a volatile deodorizing fragrant agent is applied to the outer periphery and a deodorizing region with polyphenol or its derivatives is applied to the inner periphery, utilizing ester-based compounds like citronellyl formate and phenylethyl formate for chemical deodorization and fragrance release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a deodorant is coated on the inner surface of a paper tube, then the deodorant is carried on the paper tube, but the amount of deodorant is small and it is covered by adhesive component
Solution Approach 1:
The deodorizing function is segmented into two separate locations: the inner surface of the paper tube (for sustained deodorizing) and the outer surface of the paper tube (for immediate effect). This segmentation allows each surface to be optimized for its specific function without interference from adhesive components on the inner surface.
Solution Approach 2:
The deodorant application is extended from a single-dimensional inner surface coating to a two-dimensional approach by also applying deodorant to the outer surface of the paper tube. This dimensional expansion increases the total deodorant capacity and provides both immediate and sustained deodorizing effects.
2Object-affected harmful factors
If fragrance is applied to mask malodor, then malodor is modulated or masked, but a large amount of fragrant agent is used and fragrance may be excessively strong
Solution Approach 1:
Instead of merely masking malodor with fragrance, the invention converts the fragrant agent into a chemical deodorizing substance that actively decomposes malodorous components. The ester-based compounds react with ammonia and other odor-causing substances, transforming the harmful malodor into harmless substances while producing a pleasant fragrance as a byproduct.
Solution Approach 2:
The chemical properties of the fragrant agent are changed by selecting ester-based compounds with specific deodorizing capabilities. These compounds have different chemical reactivity parameters that enable them to chemically react with and decompose malodorous components rather than simply masking them, thereby reducing the total amount of fragrant agent needed.
3Reliability
If a deodorant is impregnated in a paper tube for neutralizing effect, then ammonia is decomposed, but contact between ammonia and deodorant is required so immediate effect on diffused ammonia cannot be expected
Solution Approach 1:
The deodorizing function is segmented into two separate locations: the inner surface of the paper tube (for sustained deodorizing through contact) and the outer surface of the paper tube (for immediate effect on diffused ammonia). This segmentation allows each surface to be optimized for its specific function without interference from adhesive components on the inner surface.
Solution Approach 2:
The deodorant is pre-applied to both the inner and outer surfaces of the paper tube during manufacturing, so that it is immediately available to react with ammonia as soon as it is generated or diffuses into the toilet space, eliminating the delay associated with applying deodorant after ammonia release.
4Reliability
If deodorant is applied to paper tube, then deodorizing effect is provided, but it is difficult to recognize whether the deodorant effect is exhibited
Solution Approach 1:
The invention uses the presence and intensity of fragrance as an indicator of deodorant effectiveness. As the ester-based deodorizing compounds chemically react with and decompose malodorous components, they release a pleasant fragrance that serves as a visible (olfactorily) indicator that the deodorant is actively working. The strength of the fragrance correlates with the level of deodorizing activity.
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
This design provides an immediate and sustained deodorizing effect on ammonia and other malodorous components, ensuring the deodorant remains effective and easy to recognize, with reduced fragrant agent usage and improved manufacturing stability.
Implementation Method 1
a volatile deodorizing fragrant agent that is vaporized to emit fragrance and chemically deodorizes a malodorous component
Implementation Method 2
a deodorizing region to which a deodorant that chemically deodorizes a malodorous component is applied for deodorizing a malodorous component by contact with the malodorous component
