Solution Overview

Problem

Existing cleaning tools with elongated handles lack effective interchangeable head systems that allow for quick and easy attachment and detachment of various cleaning tool head accessories, limiting their versatility and functionality.

Innovation Solution

A tool head clamping system utilizing a novel male clip member and female clip member connection, where the male clip member is configured with resilient tabs and slots to securely attach and detach various cleaning elements from a mop or elongated handle, enabling easy interchangeability of cleaning tool head accessories.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a traditional fixed cleaning tool head design is used, then the tool structure is simple and reliable, but the versatility and adaptability are limited as only one cleaning function is provided

Engineering Contradiction:
ImproveversatilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cleaning tool is divided into two separable parts: a handle and an interchangeable tool head. The tool head can be detached and replaced with different cleaning elements (mop heads, brush heads, etc.), allowing one handle to perform multiple cleaning functions. This segmentation enables versatility without requiring multiple complete tool sets.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The handle is designed with a universal clamping mechanism that can accommodate various types of tool heads and cleaning elements. The female clip member on the handle works with male clip members on different tool heads, creating a universal system where one handle can perform multiple cleaning functions (mopping, scrubbing, sweeping, etc.).

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If an interchangeable tool head system is implemented, then the versatility and adaptability are improved, but the attachment and detachment process becomes more complex and time-consuming

Engineering Contradiction:
ImproveinterchangeabilityVSAvoidattachment ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The clamping mechanism incorporates resilient (spring-loaded) tabs that automatically engage with corresponding slots on the tool head. This dynamic spring-loaded connection allows for quick, tool-free attachment by simply pushing the tool head onto the handle, and easy detachment by releasing the engagement. The resilient nature of the tabs provides automatic locking without requiring manual fastening operations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The clamping system is designed to automatically secure the tool head to the handle through the engagement of resilient tabs with slots. The spring-loaded tabs self-engage when the tool head is pushed onto the handle, eliminating the need for manual fastening or complex locking mechanisms. The system serves itself by automatically creating a secure connection through its inherent elastic deformation and geometric interlocking.

Inventive Principle:
Principle #25Self-service

AI summary

A tool head clamping system allows for the interchangeability of various cleaning tool head accessories. These accessories are connected by a clip assembly to a mop handle or like elongated hand tool handle. The system utilizes a novel male clip member to female clip member connection, with the female clip member located on the end of the elongated tool handle, and a tool head accessory consisting of the male clip member configured to have a variety of cleaning elements.
