Flat Mop Trigger Mechanism for Touch-Free Cloth Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-operated flat mops require users to touch dirty cleaning cloths to discard them, posing a hygiene concern.
Innovation Solution
A single trigger mechanism is introduced, comprising a top plate, mechanical plate, and push plate, allowing for the release of dirty microfiber or non-woven cloths without direct hand contact by using force springs and a ratchet collar mechanism to separate the push plate from the mechanical plate, enabling the cloth to be disposed of without touching it.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the push plate is retained against the mechanical plate to hold the cloth, then the cloth retention is secure, but the user must touch the dirty cloth to remove it
Solution Approach 1:
The trigger mechanism serves as an intermediary device between the user and the dirty cloth. When the trigger is activated, it releases the push plate from its retained position against the mechanical plate, allowing the cloth to be removed without direct hand contact. This mediator mechanism resolves the contradiction by enabling easy cloth removal while preventing hygiene contamination.
Solution Approach 2:
The spring-loaded push plate system enables self-service cloth removal. The spring stores energy to automatically push the cloth away from the mechanical plate when the trigger is activated, eliminating the need for manual handling of the dirty cloth. This self-service mechanism allows the cloth to be discarded without user contact, resolving the hygiene issue while maintaining ease of operation.
2Object-affected harmful factors
If a trigger mechanism is added to release the push plate, then hygiene is improved, but the device complexity increases
Solution Approach 1:
The trigger mechanism is implemented locally within the handle assembly rather than as a separate system. The trigger, linkage, and spring components are integrated into the existing handle structure, adding hygiene functionality without significantly increasing overall device complexity. This localized implementation resolves the contradiction by providing hygiene protection with minimal added complexity.
Solution Approach 2:
The trigger mechanism uses simple, inexpensive components such as a spring, trigger lever, and linkage that can be easily manufactured and assembled. These components are designed for straightforward operation and replacement if needed, enabling hygiene improvement without substantial complexity increase. The simplicity of these disposable-like components resolves the contradiction between hygiene and complexity.
