Trigger-Activated Cleaning Assembly for Cross-Contamination-Free Agent Change
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hard surface cleaning and conditioning assemblies face difficulties in ease of use, particularly when dealing with large surface areas, leading to user fatigue due to inefficient motion and potential cross-contamination of conditioning agents.
Innovation Solution
A hard surface cleaning and conditioning assembly with a removable container and dispensing valve that allows for easy conversion between agents without purging, featuring a pole, trigger, and agent dispensing device with an activation arm that moves between positions to open and close the dispensing valve, ensuring no internal volume for fluid communication, thus preventing cross-contamination and improving ease of movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the assembly uses internal fluid communication channels to dispense conditioning agents, then the dispensing function is achieved, but cross-contamination between different conditioning agents occurs
Solution Approach 1:
The patent removes internal fluid communication channels from the dispensing assembly, extracting the source of cross-contamination. The assembly now lacks any internal volume that can fluidly communicate with the container, eliminating the risk of conditioning agent residue causing contamination between different agents.
Solution Approach 2:
The patent introduces a dispensing valve as an intermediary component that interfaces directly with the container opening. This valve acts as a mediator between the container and the application tool, allowing conditioning agent transfer without requiring internal fluid channels within the assembly housing.
2Adaptability or versatility
If the assembly is designed to accommodate multiple container types, then versatility is improved, but ease of operation deteriorates due to difficulty in conversion
Solution Approach 1:
The dispensing assembly is designed with a universal interface that can accommodate multiple container types including pails, drums, and backpacks. The valve mounting structure and activation mechanism are standardized to work with various container configurations, enabling one assembly to serve multiple functions.
Solution Approach 2:
The assembly incorporates a removable valve system that can be dynamically configured for different container types. The valve can be easily removed and replaced or repositioned to accommodate different container openings, allowing rapid adaptation without complex reconfiguration.
3Productivity
If the assembly uses traditional dispensing mechanisms, then the dispensing function is achieved, but user fatigue increases due to inefficient motion
Solution Approach 1:
The dispensing system is designed to be self-regulating through the valve mechanism that responds automatically to trigger activation. The system eliminates the need for manual pumping or complex actuation mechanisms, allowing the user to simply trigger the valve and the conditioning agent flows automatically based on the applied force to the surface.

AI summary
A hard surface cleaning and conditioning assembly is provided for use with a removable container having a dispensing valve that moves between a closed state and an open state. The assembly includes a pole; a trigger that moves between a normal position and an activated position; a tool depending from the pole remote from the trigger; and an agent dispensing device depending from the pole. The agent dispensing device has an activation arm operatively coupled to the trigger. The activation arm moving between a first position when the trigger is in the normal position and a second position when the trigger is in the activated position. The agent dispensing device has a housing into which at least a portion of the dispensing valve can be removably positioned to be activated by the activation arm.
