Solution Overview

Problem

Existing mechanical release aids for mop cover holders require vertical upward movement, which can damage overhead objects and necessitate manual handling of dirty mop covers, posing safety risks and operational inefficiencies.

Innovation Solution

A release device with a frame that includes a stop and pivot point support area, allowing the handle to pivot rather than move linearly, reducing the required movement space and avoiding vertical lifting, and incorporating a design that guides the mop cover into a collection container safely.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a mechanical release aid requires vertical upward movement to release the mop cover, then the locking mechanism can be reliably released, but overhead objects may be damaged and manual handling of dirty mop covers is required

Engineering Contradiction:
Improvelocking mechanism release reliabilityVSAvoiddamage to overhead objects
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The invention changes the movement direction from vertical (upward) to horizontal (lateral). The mop cover holder is moved sideways along the longitudinal axis of the handle rather than being lifted vertically, thereby releasing the locking mechanism without risking damage to overhead objects.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

Instead of lifting the mop cover holder upward to release the lock, the invention inverts the approach by moving it horizontally in the longitudinal direction. This reverse movement strategy achieves the same locking release function while avoiding the harmful vertical motion.

Inventive Principle:
Principle #13The other way round (Inversion)

2Device complexity

If manual handling of dirty mop covers is required, then the release mechanism can be simple, but operational efficiency decreases and contamination risk increases

Engineering Contradiction:
Improverelease mechanism simplicityVSAvoidoperational efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The system enables self-service by allowing the mop cover to be automatically ejected into a collection container through the lateral movement mechanism. The holder's motion along the longitudinal axis automatically releases and deposits the mop cover, eliminating the need for manual handling and improving operational efficiency.

Inventive Principle:
Principle #25Self-service
