Solution Overview

Problem

Existing extension handles and poles require multiple connection mechanisms to accommodate different implements, leading to user discomfort and increased storage and transportation needs.

Innovation Solution

A dual-ended handle with a pole featuring a first end with a threaded fastener and tapered cone for one implement connection, and a second end with a locking member and threaded fastener for another, allowing a single grip to securely engage both ends and switch between different implement connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple different connection mechanisms are used to accommodate different implements, then the implement can be compatible with various implements, but the user must obtain, store and transport multiple different handles or poles

Engineering Contradiction:

Improvecompatibility with various implementsVSAvoidnumber of handles or poles needed

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The handle is designed with dual-ended functionality where one end features a threaded fastener connection mechanism and the other end features a locking member connection mechanism. This allows a single handle to be compatible with multiple different implements that use different connection types, eliminating the need for users to maintain multiple separate handles or poles for different tasks.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple different handles or poles are obtained to accommodate different connection mechanisms, then compatibility with various implements is achieved, but storage and transportation requirements increase

Engineering Contradiction:

Improvecompatibility with various implementsVSAvoidstorage and transportation space

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The invention merges two different connection mechanisms (threaded fastener and locking member) into a single handle structure. By integrating both connection types at opposite ends of the same handle, the design consolidates what would traditionally require two separate handles into one unified tool, thereby reducing storage and transportation volume.

Inventive Principle:

Principle #5Merging (Combining)

3Quantity of substance

If a single handle is designed to accommodate multiple connection mechanisms, then the number of handles needed is reduced, but the handle structure becomes more complex

Engineering Contradiction:

Improvenumber of handles neededVSAvoidhandle structure

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The handle is segmented into two distinct ends, each equipped with a different connection mechanism. The first end contains a threaded fastener while the second end contains a locking member. This segmentation allows each end to independently serve different implement types without requiring a completely complex integrated system, thereby managing structural complexity through functional division.

Inventive Principle:

Principle #1Segmentation

AI summary

A dual ended handle such as that used with cleaning implements is provided. The dual ended handle comprises a pole with a first end and a second end, the first end having a first threaded fastener and an implement connecting feature having a tapered cone, the second end having a second threaded fastener and a locking member. A grip having a first end is configured to releasably engage at least one of the first threaded fastener or the implement connecting feature, and a second end configured to releasably engage the second threaded fastener.
