Surface-Mount Cartridge Holder-Ejector for Consistent Trash-Can Air Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trash-can sanitization devices face challenges in maintaining consistent disinfectant/deodorizer dissemination and retention during trash-bag removal or emptying, with a need for improved methods and devices that minimize user exposure to contamination.
Innovation Solution
A surface mount air disinfectant/deodorizer holder-ejector device with a 'H'-shaped mechanism, including thumb-finger compressible lower arms, inward projections, and a top-flanged cup, allows for controlled dispensation and reuse by using disposable or refillable cartridges with a spring mechanism for secure mounting and easy replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional trash-can sanitization device is used, then disinfectant/deodorizer dissemination is provided, but the device fails to maintain retention during trash-bag removal or emptying and requires frequent replacement
Solution Approach 1:
The device employs a spring-loaded ejection mechanism that dynamically adapts to different operational states. The spring-loaded plunger automatically ejects the cartridge when needed, while the resilient nature of the spring allows the device to maintain retention during normal operation but facilitate easy replacement when required
Solution Approach 2:
The device performs self-service through its spring-loaded ejection mechanism that automatically propels the cartridge into position and secures it without requiring manual intervention for each dispensing action, thereby maintaining reliable retention while enabling easy replacement when the cartridge is depleted
2Ease of operation
If a disposable cartridge system is used, then product replacement is simplified, but user exposure to contamination increases during replacement
Solution Approach 1:
The device utilizes disposable cartridges that are discarded after use, eliminating the need for cleaning and sanitization of the cartridge itself. This allows users to simply replace the entire cartridge unit, minimizing exposure to contamination while maintaining ease of operation
Solution Approach 2:
The device is segmented into a reusable holder component and a disposable cartridge component. This segmentation allows the cartridge to be easily removed and replaced as a separate unit, simplifying the replacement process and reducing user exposure to contamination by isolating the disposable element
3Reliability
If a complex mounting mechanism is used, then device retention is improved, but device complexity increases
Solution Approach 1:
The complex mounting mechanism is extracted into a separate surface-mountable base unit that can be independently installed on the trash can. This separates the retention function from the dispensing mechanism, allowing the holder to provide secure retention while the cartridge replacement remains simple
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures consistent and controlled dispensation of disinfectants/deodorizers while minimizing user exposure to contamination, facilitating easy replacement and reuse of the device.
Implementation Method 1
Out-stretched spring fitted to the interior center base of the top-flanged cup that suspends a flat-plate which may freely move in the cup but restricted by the cup flange

AI summary
Devices, systems, and methods are disclosed for facilitation of continuous release of fluids or vaporizable solids using disinfectants, deodorizers, repellants, etc., into an enclosed unit, such as trash-can in consistent and predictable amounts. The device generally includes a surface mount holder-ejector device in the resemblance of letter “H”; inward slanted upper arm as in the upper arm of letter “H”; inward slanted lower arm as in lower arm of letter “H”; or slightly curve bilateral arms as in letter “H” that may have thumb-finger fitting. The device has an encasement unit with holder-ejection mechanism mounted on the horizontal arm of the device as in the horizontal arm of letter “H”. Device can be utilized with modified disposable or refillable fluid container cartridge adaptable to the device, and device surface wall affixer. The lower “H” shaped arms of the device may be thumb-finger compressed to cause outward pull of the two upper “H” shaped arms of the device to allow insertion or ejection process of the cartridge. The ends of the two upper arms of the device have inward projection forming stoppers/internal grip surface that causes retention of the cartridge in the device and restricting outward pressure by the spring and flat-plate beneath the cartridge.
