Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trash cans fail to effectively eliminate waste odors and prevent bacterial growth, leading to air pollution and health issues, with current solutions like deodorizing bags and agents being costly, complicated, and inconvenient.
Innovation Solution
A trash container equipped with an ultrasonic deodorizing device that injects deodorant in an atomization manner through an ultrasonic nozzle, controlled to actuate when the lid is closed or after a predetermined idling time, simplifying operation and integrating with the lid mechanism without altering the container's structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If deodorizing bags made of deodorizing material are used to remove odors from waste material, then odor elimination is improved, but manufacturing cost increases and deodorizing power becomes limited
Solution Approach 1:
The patent replaces the passive chemical absorption mechanism of deodorizing bags with an active ultrasonic atomization system. The ultrasonic nozzle generates fine mist droplets through mechanical vibration at ultrasonic frequencies, enabling active delivery of deodorizing agent throughout the container space rather than relying on passive diffusion from bag material.
Solution Approach 2:
The patent changes the physical state and delivery parameters of the deodorizing agent. Instead of using solid or liquid deodorizing material in bag form, the system transforms the deodorizing agent into a fine aerosol mist through ultrasonic atomization, dramatically increasing surface area and distribution efficiency for enhanced odor elimination.
2Object-affected harmful factors
If a deodorizing applicator is incorporated into the trash can, then deodorizing function is added, but device complexity increases and manufacturing cost highly increases
Solution Approach 1:
The ultrasonic nozzle serves multiple functions: it atomizes the deodorizing agent, distributes it throughout the container, and can be controlled to operate at different times (when lid opens, when lid closes, or periodically). This multi-functionality eliminates the need for separate deodorizing applicator mechanisms.
Solution Approach 2:
The system uses the existing lid mechanism's motion (opening/closing) to trigger deodorizing cycles automatically. The control system monitors lid position and activates the ultrasonic nozzle accordingly, eliminating the need for manual operation or complex separate actuation mechanisms for the deodorizing function.
3Object-affected harmful factors
If deodorizing agent is applied via applicator, then odor elimination is attempted, but ease of operation deteriorates as user must operate lid and applicator individually
Solution Approach 1:
The control system continuously monitors the lid's position and operational state, using this feedback to automatically determine when to activate the ultrasonic nozzle. When the lid opens or closes, or based on timing cycles, the system automatically initiates deodorizing without requiring user input, creating a seamless integrated operation.
Solution Approach 2:
The trash can's lid mechanism itself triggers the deodorizing function through automatic detection of lid position changes. The system serves itself by using the necessary mechanical motion (lid opening/closing) as the trigger signal for deodorizing, eliminating the need for separate user actions.
4Object-affected harmful factors
If ultrasonic nozzle is controlled to actuate at different conditions, then deodorizing effectiveness is improved, but control complexity increases
Solution Approach 1:
The control system uses feedback from lid position sensors and timing circuits to automatically determine optimal deodorizing moments. The system monitors when the lid opens and closes, and uses this information along with predetermined timing intervals to trigger ultrasonic nozzle operation, achieving adaptive control without complex user programming.

AI summary
A trash container includes a container unit and an ultrasonic deodorizing device. The container unit includes a container having a top opening and a container cavity, and a container cover being moved between an opened position and a closed position. The ultrasonic deodorizing device includes a deodorizing carrier supported above the top opening of the container body for containing deodorant in liquid form, an ultrasonic nozzle operatively coupled at the deodorizing carrier for downwardly injecting the deodorant in an atomization manner below the top opening of the container body, and a nozzle controller configured to control and activate the ultrasonic nozzle.
