Isolator Cleaning Tool Head for Hands-Free Pad Handling

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing cleaning tools for isolators require significant fine motor skills to attach and detach pads, are cumbersome with heavily gloved hands, lack flexibility and maneuverability, and do not provide a means to store clean and soiled pads within the controlled environment, leading to inefficiency and potential cross-contamination.

Innovation Solution

A lightweight, ergonomic cleaning tool with an adjustable handle and asymmetrical tool head design, featuring a quick-release mechanism and hands-free pad attachment/detachment system, integrated with a packaging tray that allows for easy storage and management of clean and soiled pads, ensuring minimal contamination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional cleaning tools are used to attach and detach pads, then cleaning function is provided, but significant fine motor skills are required making it difficult and cumbersome with heavily gloved hands

Engineering Contradiction:

Improvepad attachment and detachmentVSAvoidfine motor skill requirement

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The pad assembly is designed with a self-aligning mechanism where the pad automatically positions itself on the tool head frame during attachment, eliminating the need for precise manual alignment by the operator wearing heavily gloved hands

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The cleaning tool is divided into modular components (tool head frame, pad assembly, handle) that can be independently manipulated and assembled, allowing each component to be optimized for ease of handling with gloved hands

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If traditional cleaning tools are used in small spaces, then cleaning of hard-to-reach areas is attempted, but maneuverability is limited due to long tool handles

Engineering Contradiction:

Improveaccess to hard-to-reach areasVSAvoidmaneuverability in confined spaces

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The tool head frame incorporates a pivoting mechanism that allows the frame to dynamically adjust its angle and orientation relative to the handle, enabling the operator to reach hard-to-access areas while maintaining control and maneuverability in confined spaces

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The tool head frame features an asymmetrical design with different geometries at different locations, allowing specific portions of the frame to access particular hard-to-reach areas while the overall tool maintains manageable proportions for operator control

Inventive Principle:

Principle #3Local quality

3Productivity

If traditional cleaning tools are used for pad handling, then cleaning operation is performed, but cross-contamination risk increases due to operator contact with soiled pads

Engineering Contradiction:

Improvecleaning operation efficiencyVSAvoidcross-contamination risk

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The tool head frame automatically secures the pad assembly through a snap-fit or friction-fit mechanism that engages without operator contact with the pad surface, and automatically releases the pad for removal, eliminating the need for operators to touch soiled pads and reducing cross-contamination risk

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The tool head frame acts as an intermediary between the operator and the pad assembly, allowing the operator to manipulate the pad indirectly through the frame structure rather than direct contact with the pad surface, thereby reducing contamination risk

Inventive Principle:

Principle #24Intermediary (Mediator)

4Adaptability or versatility

If traditional cleaning tools are used, then cleaning function is provided, but flexibility and adaptability to access detail areas is insufficient

Engineering Contradiction:

Improveaccess to detail areasVSAvoidtool design flexibility

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The pivoting tool head frame provides dynamic adaptability, allowing the frame to rotate and adjust its orientation to access various detail areas and angles within the isolator, enhancing the tool's versatility without requiring multiple specialized tools

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The asymmetrical tool head frame design features non-uniform geometries and attachment points that provide superior access to specific detail areas and hard-to-reach surfaces compared to symmetrical designs, increasing adaptability for targeted cleaning tasks

Inventive Principle:

Principle #4Asymmetry

AI summary

An apparatus for cleaning a controlled and regulated equipment, wherein the apparatus comprises a tool handle including a first handle portion removably connected to a second handle portion and a tool head frame pivotably connected to the second handle portion. The tool head frame further comprises a leading edge opposite a trailing edge and a first side edge opposite a parallel second side edge disposed between the leading edge and the trailing edge respectively wherein the leading edge and the trailing edge are non-parallel to each other—forming a trapezoidal shaped tool head frame.
