Trash Container Liquid Dispensing Device with Piston Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current trash container treatment systems are inefficient and hazardous for drivers, as they require repeated manual spraying of disinfectants and odor suppressors into large numbers of containers, leading to time consumption and potential health risks.
Innovation Solution
A liquid dispensing device integrated with trash containers that uses a manually operated pump and various nozzles for selective spraying, including a locking mechanism to prevent spraying during transport, and a float valve for automatic dispensing based on liquid levels, allowing for efficient and safe treatment of interior surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If manual spraying by driver is used, then treatment can be performed, but time consumption increases and driver exposure to harmful materials occurs
Solution Approach 1:
The spray system is integrated into the trash container itself, enabling the container to be treated automatically without requiring the driver to manually spray each container. The system uses the container's own structure (piston, reservoir, nozzle) to perform the spraying function, eliminating the need for external intervention and reducing driver exposure time to harmful materials.
Solution Approach 2:
The spraying function is extracted from the driver's manual task and embedded directly into the container structure. By integrating the spray reservoir, piston, and nozzle into the container, the treatment function becomes an inherent capability of the container rather than an external operation performed by the driver.
2Reliability
If manual spraying procedure is required for each container, then treatment can be applied, but productivity decreases due to repetitive tasks
Solution Approach 1:
Each container is equipped with its own automated spray system that activates during the dumping process. The piston mechanism automatically dispenses the treatment material when the container is upended, ensuring consistent treatment without requiring the driver to manually service each container, thereby maintaining reliability while dramatically improving productivity.
Solution Approach 2:
The treatment material is pre-loaded into the container's integrated reservoir before the container is filled with trash. The spray system is pre-positioned within the container structure, ready to automatically dispense the treatment material at the appropriate moment during the dumping process, eliminating the need for on-site manual spraying.
3Object-affected harmful factors
If spray tank and hose arrangement is used, then treatment can be performed, but device complexity increases and operation becomes cumbersome
Solution Approach 1:
The spray reservoir, piston mechanism, and nozzle are merged into a single integrated assembly that is built into the container structure. This eliminates the need for separate spray tanks, hoses, and mounting hardware, simplifying the overall system while still providing automated treatment functionality that protects the driver from exposure.
Solution Approach 2:
The spray system components are nested within the container structure itself. The reservoir is positioned within the container body, the piston mechanism is housed within the container walls, and the nozzle is integrated into the container's existing features, creating a compact nested arrangement that minimizes added complexity.

Function Achieved in This Case
The system enables thorough and efficient treatment of trash containers with reduced exposure risks for drivers, saving time and ensuring consistent sanitation, while allowing for customizable spray patterns and materials usage.
Implementation Method 1
The piston and actuator component may be moved from a first position to a second position and back to the first position thereby forcing liquid compound into the inside of the trash container through the nozzle
Implementation Method 2
The liquid dispensing device may include a float valve for automatically controlling the liquid level in the reservoir
Implementation Method 3
The nozzle may be shaped and adapted to spray a liquid on at least a portion of the interior of a trash container
