Ergonomic multifunctional tool holder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tools and holders fail to position tools at multiple angled positions along the X, Y, and Z axes, leading to inefficient and unsafe working conditions when reaching high areas, resulting in musculoskeletal disorders and insecure work environments.
Innovation Solution
A multifunctional tool holder with a handle and interconnection unit that allows for secure positioning of tools at various angles, adaptable to a conventional extension pole, featuring a cylindrical body with protrusions and wedges for adjustable coupling, enabling ergonomic positioning along multiple axes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional holders are used to hold painting tools, then the tool can be positioned in predetermined angles within the same plane, but the holder cannot adapt to multiple angles of high areas or objects installed in high locations
Solution Approach 1:
The holder is divided into multiple independent components: a handle, an interconnection unit with first and second coupling points, and a tool-carrying unit. Each segment can be independently positioned and angled, allowing the tool to reach high areas at various angles without requiring a completely complex redesign of the entire holder structure.
Solution Approach 2:
The holder transitions from fixed two-dimensional planar positioning to three-dimensional multi-angular positioning. The interconnection unit enables the tool-carrying unit to be angled relative to the handle in multiple dimensions (X, Y, and Z axes), allowing adaptation to high areas and objects at various orientations without excessive structural complexity.
2Ease of operation
If ladders, cradles, or scaffolds are used to reach high areas, then the worker can access difficult-to-reach places, but the worker must consistently move and reposition the working materials, which is time-consuming and inefficient
Solution Approach 1:
The holder incorporates adjustable and reconfigurable components that allow the tool position and angle to be dynamically changed without moving the entire extension pole or repositioning heavy equipment. The interconnection unit enables quick angular adjustments, reducing the time lost to repositioning while maintaining easy access to high areas.
3Length of stationary object
If conventional extension poles are used with fixed-angle holders, then the tool can reach high areas, but the worker must assume stressful postures leading to musculoskeletal disorders
Solution Approach 1:
The holder allows dynamic adjustment of the tool angle and position relative to the extension pole. This enables the worker to optimize their posture for each specific task by positioning the tool at the most convenient angle, reducing strain on the body while maintaining the reach provided by the extended pole length.
Solution Approach 2:
The holder enables changes in the angular parameters of tool positioning. By adjusting the angle of the tool-carrying unit relative to the handle, the worker can modify the tool's orientation to match ergonomic requirements, reducing musculoskeletal stress while preserving the extended reach capability.
4Adaptability or versatility
If specialized nonconventional painting tools are designed with fixed angular positions, then the tool can be positioned in specific angles, but the tool is designed only for that specific exclusive tool and cannot be adapted to other tools
Solution Approach 1:
The holder is designed as a universal system that can accommodate various painting and maintenance tools. The standardized handle with threaded borehole and the interconnection unit with multiple coupling points create a platform that can be adapted to different tool types, providing positioning flexibility without requiring specialized complex structures for each specific tool.

AI summary
The invention is directed to an ergonomic tool holder, adaptable to a conventional pole and having a handle and a supporting base. These are coupled to an interconnecting unit in a non-permanent manner. The coupling of the handle to the interconnecting unit and the coupling of the supporting base to the interconnecting unit allows the tool holder to be assembled, having the handle in straight or multiple angled positions with regard to the supporting base and wherein the tool may be held and positioned along the X-X, Y-Y, or Z-Z axes. A given conventional utensil used in working activities such as painting or maintenance may be clamped and secured on the supporting base. Thus, the User may position such utensils in the tool holder straight or in the angled position at their convenience and may change such positions easily and quickly.
