Solid fragrance carrier and method of use in a vacuum cleaner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaners lack an efficient and cost-effective method to provide a pleasant fragrance or deodorizing solution that does not compromise suction power or increase system resistance, as traditional methods often require additional containers or materials that can affect airflow and require higher energy usage.
Innovation Solution
A method involving the formation of a solid fragrance carrier using a fragrance-infused polymeric gel or hot melt adhesive, which is applied to the filter elements or filter bags within vacuum cleaners, allowing the fragrance to be emitted as air passes through, thus providing a pleasant scent without increasing airflow resistance or requiring additional containers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If traditional fragrance containers or materials are added to vacuum cleaners, then fragrance or deodorizing function is provided, but suction power is compromised and system resistance increases
Solution Approach 1:
The patent combines the fragrance delivery function with the existing filter element by applying fragrance-containing materials directly to the filter surface or integrating fragrance capsules within the filter structure. This merging eliminates the need for separate fragrance containers that would obstruct airflow, while still providing effective fragrance and deodorizing functions through the filter media itself.
Solution Approach 2:
The filter element is designed to serve multiple functions simultaneously: filtration of particles from the air stream and delivery of fragrance compounds. By incorporating fragrance materials into the filter structure, the single component performs both air cleaning and odor control, avoiding additional parts that would increase system resistance and energy consumption.
2Object-generated harmful factors
If traditional fragrance containers or materials are added to vacuum cleaners, then fragrance or deodorizing function is provided, but device complexity increases
Solution Approach 1:
The fragrance delivery system is merged with the filter element, eliminating the need for separate containers, mounting structures, and distribution mechanisms. The fragrance material is applied directly to the filter or integrated into its structure, reducing the number of parts and simplifying the overall device architecture while maintaining effective fragrance delivery.
Solution Approach 2:
The filter element is designed to serve multiple functions simultaneously: filtration of particles from the air stream and delivery of fragrance compounds. By incorporating fragrance materials into the filter structure, the single component performs both air cleaning and odor control, avoiding additional parts and simplifying the device structure.
3Object-generated harmful factors
If traditional fragrance containers or materials are added to vacuum cleaners, then fragrance or deodorizing function is provided, but manufacturing cost increases
Solution Approach 1:
The fragrance delivery function is combined with the filter element manufacturing process. Fragrance materials are applied to the filter during production or through simple post-processing methods, eliminating the need for separate fragrance container fabrication, assembly, and installation steps. This integration reduces manufacturing complexity and cost while providing effective fragrance delivery.
Solution Approach 2:
The patent employs cost-effective fragrance delivery methods using readily available fragrance materials and simple application techniques. The fragrance-containing filter or integrated fragrance capsules provide effective deodorizing function at lower cost compared to traditional separate container systems, aligning with the principle of using economical solutions for fragrance delivery.
