Seat-Integrated Odor Filtration for Source Capture in Enclosed Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Body waste odor air expelled by a person contaminates enclosed spaces due to inefficient air ventilation, with existing solutions failing to effectively remove the odor at its source.
Innovation Solution
A seat with a built-in odor air cleaning system featuring a telescopic tube, odor filter filled with active charcoal, and blower system that automatically detects and absorbs odor air, ensuring it is cleaned and released back into the atmosphere, with accessible components for easy maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If ventilation means are used to remove odor air from a room or compartment, then the odor air can be removed from the enclosed space, but the ventilation means are normally located far from the person expelling the odor air, thus the offensive odor air must travel a relatively long distance and may still disperse in the atmosphere and be detected by other people
Solution Approach 1:
The invention extracts the odor air removal function from the centralized ventilation system and places it directly at the seat where the odor is generated. The seat incorporates an odor filter and suction mechanism that captures odor air at the source, eliminating the need for long-distance transport through the enclosed space.
Solution Approach 2:
The seat acts as an intermediary device between the person expelling odor air and the ventilation system. It provides a localized odor capture and filtration mechanism that bridges the gap between odor generation and removal, preventing odor dispersion before it can spread through the enclosed space.
2Object-affected harmful factors
If a built-in odor air cleaning system with multiple components is integrated into the seat, then odor air can be effectively removed and cleaned at its source, but the device complexity increases with multiple components including telescopic tube, odor filter, and blower system
Solution Approach 1:
The invention merges multiple odor removal functions (suction, filtration, and air movement) into a single integrated seat unit. The telescopic tube, odor filter, and blower system are combined in one compact arrangement that fits within the seat structure, reducing the need for separate distributed components.
Solution Approach 2:
The seat serves multiple functions: it provides seating support while simultaneously incorporating an odor air cleaning system. The integrated design allows the same structure to fulfill both mechanical support and environmental control functions, reducing overall system complexity.
3Ease of repair
If the odor filter is removably mounted in the air conducting compartment, then the components parts are readily accessible for easy repair or replacement, but the mounting structure requires additional design considerations for secure yet accessible installation
Solution Approach 1:
The odor filter is designed as a separate, removable component that can be independently accessed and replaced. The air conducting compartment is segmented to allow easy access to the filter without disassembling the entire seat structure, facilitating simple maintenance operations.
Solution Approach 2:
The mounting structure provides dynamic accessibility, allowing the odor filter to be securely mounted during operation but easily removed for maintenance. The design transitions between a fixed secure state during use and an accessible state during servicing.

AI summary
An odor air cleaning seat is provided with an opening for receiving body waste odor air expelled by a person sitting thereon. A odor air sensor is mounted in the opening for detecting the presence of odor air expelled by the person. An odor filter is mounted in a conducting compartment located below the seat. At least one air blower is provided in the conducting compartment for drawing the odor air to flow through the conducting compartment for cleaning and removing the offensive odor of the odor air.
