Adjustable Tool Hook Mounting for Flexible Handle Positioning

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing portable tools with hooks lack the ability to change the hook's position and distance from the handle, limiting their operability and usability depending on the object being secured.

Innovation Solution

A portable tool design featuring a hook with a mounting device that allows the hook body to be oriented and positioned in various directions and at different distances along the handle, enabling flexible mounting on either side and adjusting for different thicknesses of objects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the hook is disposed at a fixed position proximal to the rear end of the handle, then the hook does not interfere with the operation of the tool, but the operability and versatility are limited

Engineering Contradiction:

Improvehook operabilityVSAvoidhook positioning flexibility

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The hook is designed to be movable along the handle rather than fixed, allowing it to dynamically adjust its position. The mounting device includes a slot or guide structure that permits the hook to slide to different locations, enabling the operator to optimize the hook's position based on the specific task or object being handled.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The hook mounting system is divided into separate components: the hook body, the mounting device with positioning features (such as slots, guides, or adjustable brackets), and the handle. This segmentation allows the hook to be independently positioned and adjusted along the handle without affecting the overall tool structure.

Inventive Principle:

Principle #1Segmentation

2Device complexity

If the hook is made fixed on one side of the handle, then the structure is simple, but the position cannot be changed between left side and right side

Engineering Contradiction:

Improvemounting structureVSAvoidhook side positioning

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The mounting device is designed with symmetric or bidirectional positioning capabilities, allowing the hook to be mounted on either the left or right side of the handle. The mounting structure includes features such as opposing slots, guides, or attachment points that enable the hook to be positioned on both sides, making the tool adaptable to different user preferences and applications.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of manufacture

If the hook distance from the handle is fixed, then the manufacturing is simple, but the distance cannot be adjusted for different objects

Engineering Contradiction:

Improvehook mountingVSAvoidhook distance adjustment

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The mounting device incorporates adjustable positioning mechanisms such as slots of varying lengths, movable brackets, or telescopic components that allow the hook's distance from the handle to be dynamically changed. This enables the operator to adjust the hook position to accommodate different object sizes and shapes while maintaining manufacturing simplicity through standardized adjustable components.

Inventive Principle:

Principle #15Dynamics
