Solid Fragrance Carrier Integrated into Vacuum Cleaner Filter Media
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vacuum cleaners lack an effective method to provide a pleasant scent or deodorize the air stream during operation, with existing solutions often requiring additional components or complex integration with the filtration system.
Innovation Solution
A solid fragrance carrier comprising a fragrance mixed with a polymeric matrix, such as a hot melt adhesive or polymeric gel, is applied to the filter media within the vacuum cleaner, allowing the fragrance to be emitted as the air stream passes through, providing a pleasant aroma without increasing airflow resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a fragrance or deodorizing element is added to the vacuum cleaner, then the air stream can be deodorized and fragrances can be provided, but additional components and complex integration with the filtration system are required
Solution Approach 1:
The fragrance is combined with the hot melt adhesive used in the filtration system, merging the deodorizing function with the existing structural component. This eliminates the need for separate fragrance containers or additional integration steps, directly resolving the contradiction between providing fragrance functionality and maintaining system simplicity
Solution Approach 2:
The hot melt adhesive serves dual functions: as a structural bonding agent in the filtration system and as a fragrance carrier. This multi-functionality approach allows the same component to perform both mechanical and deodorizing roles, reducing overall system complexity while effective air stream treatment
2Object-affected harmful factors
If a solid fragrance carrier is applied to the filter media, then the fragrance can be emitted as air passes through, but the adhesive material must withstand vacuum cleaner operating temperatures
Solution Approach 1:
The hot melt adhesive is selected or formulated with specific thermal parameters (melting point, thermal stability) that match the vacuum cleaner operating conditions. By adjusting the adhesive's physical parameters to withstand high temperatures, the fragrance carrier maintains reliability while still enabling effective deodorizing function
Solution Approach 2:
The solution uses a composite material system where the hot melt adhesive is formulated with fragrance compounds. This composite structure allows the adhesive to simultaneously provide structural integrity at high temperatures and serve as a fragrance reservoir, resolving both the temperature reliability requirement and the deodorizing function
