Adjustable-Weight Painting Handle for Stable Miniature Work

Solution Overview

Problem

Commercial painting handles for miniatures are either too light and prone to falling when handling heavy or high-center-of-gravity objects, or too heavy and burdensome for users.

Innovation Solution

A painting handle with a base extension and top seat that allows adjustable weight by filling an accommodating space with liquid or solid materials, featuring a spiral connecting structure for stability and a multilayer shell for comfort and anti-slip grip.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Weight of moving object

If a lighter painting handle is used, then user burden is reduced, but the handle becomes prone to falling when handling heavy or high-center-of-gravity objects

Engineering Contradiction:

Improveweight of painting handleVSAvoidstability of painting handle

Core Design Contradiction:

Weight of moving objectVSReliability

Solution Approach 1:

The painting handle incorporates an adjustable weight system that allows users to dynamically modify the handle's weight based on the specific miniature work requirements. The base extension contains an accommodating space that can be filled with different amounts of material, enabling the handle to adapt its weight characteristics rather than being fixed.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The invention changes the weight parameter of the painting handle by allowing users to adjust the amount of filling material in the base extension. This enables optimization of the center of gravity position and overall weight according to different operational needs, resolving the contradiction between lightness and stability.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If a heavier painting handle is used, then stability when handling miniatures is improved, but user burden increases

Engineering Contradiction:

Improvestability of painting handleVSAvoidweight of painting handle

Core Design Contradiction:

ReliabilityVSWeight of moving object

Solution Approach 1:

The painting handle incorporates an adjustable weight system that allows users to dynamically modify the handle's weight based on the specific miniature work requirements. The base extension contains an accommodating space that can be filled with different amounts of material, enabling the handle to adapt its weight characteristics rather than being fixed.

3Ease of manufacture

If the painting handle weight is fixed, then manufacturing is simplified, but adaptability to different miniature operations is reduced

Engineering Contradiction:

Improvemanufacturing simplicity of painting handleVSAvoidadaptability to different miniature operations

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The painting handle is divided into separable components: a base extension with an accommodating space, a top seat, and a finger rest. The base extension can be separately filled with material to adjust weight, while other components remain fixed. This segmentation allows weight adjustment without complicating the manufacturing of individual parts.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The base extension serves multiple functions: it provides structural support, contains the accommodating space for weight adjustment, and houses the connection mechanism. This multi-functionality allows the handle to adapt to different operational requirements while maintaining a relatively simple overall structure.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A painting handle includes a base extension, a top seat and a finger rest. The base extension has a shell, an opening which is arranged at a free end of the shell, a first connecting portion, and an accommodation space is provided in the shell and connected with the opening. The top seat has a stand include a second connection portion that could be detachably separated from or coupled to the first connecting portion. The accommodating space can be filled in with liquid or solid materials, so that a user can freely adjust the weight of the painting handle according to the operation requirement of the work on miniature, neither the painting handle will fall down on the workbench easily, nor user will feel burdened when holding the painting handle, so that it will improve the working quality and efficiency.
