Surface cleaning device with odor management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Powered surface cleaning devices often suffer from odor management issues during operation, as they lack effective mechanisms to control and vary the release of fragrance particles, leading to inconsistent cleaning experiences.
Innovation Solution
An odor control assembly is integrated into the surface cleaning device, featuring an adjustment member that allows users to select from multiple positions to vary the output of fragrance particles, ensuring a predetermined amount is released, which can be adjusted based on user preference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If no odor control assembly is integrated, then the device structure remains simple, but fragrance output cannot be controlled or varied
Solution Approach 1:
An odor control assembly is introduced as an intermediary component between the fragrance source and the environment. This assembly includes a fragrance member with fragrance particles, an adjustment member with variable openings, and a housing that directs airflow. The adjustment member acts as a mediator that controls the interaction between the fragrance particles and the surrounding air, enabling variable fragrance output without fundamentally changing the overall device structure.
2Reliability
If fragrance particles are released without controlled amounts, then the release mechanism is simple, but the cleaning experience becomes inconsistent
Solution Approach 1:
The odor control assembly employs dynamic elements including a rotatable adjustment member with multiple selectable positions (first position, second position, etc.) that vary the opening size. The variable opening dynamically controls the amount of fragrance particles released into the airflow. This dynamic control mechanism ensures consistent and reliable fragrance delivery according to user preference, transforming a static release system into an adjustable one.
3Adaptability or versatility
If multiple components are added for odor control, then fragrance management improves, but manufacturing complexity increases
Solution Approach 1:
The odor control assembly is segmented into distinct functional components: a housing defining a cavity, a fragrance member containing fragrance particles, and an adjustment member with variable openings. Each component can be manufactured separately and then assembled together. The adjustment member is rotatably coupled to the housing, allowing independent manufacturing of each part while maintaining functional integration in the final assembly.

AI summary
A surface cleaning device includes a nozzle and an odor dial assembly. The nozzle includes a nozzle housing and a dirty air passageway. The odor dial assembly include a fragrance member and a dial body configured to be removably coupled to the nozzle housing. The dial body at least partially defines a fragrance cavity configured to at least partially receive the fragrance member and a fragrance passageway extending therethrough. The odor dial assembly is configured to transition between a plurality of user-selectable positions to adjust an amount of fragrance particles released by the fragrance member into the dirty air passageway.
