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 an interconnect unit, handle, and supporting base, featuring engaging units that allow for multiple angled positions, enabling tools to be securely clamped and positioned in ergonomic orientations relative to a conventional extension pole.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional extension poles with fixed-angle holders are used, then tools can be held at predetermined angles, but the tool angles cannot be adjusted to match the multiple angles of high areas or objects, forcing workers to assume stressful postures
Solution Approach 1:
The holder employs a dynamic adjustment mechanism with a locking system that allows the tool to be positioned at multiple angles along the X-X, Y-Y, and Z-Z axes. The adjustable structure enables workers to dynamically change the tool angle to match the work surface orientation, eliminating the need to maintain awkward postures while working on angled or elevated surfaces.
Solution Approach 2:
The holder is divided into multiple independent angular adjustment components, each capable of rotating and locking at specific angles. This segmentation allows for precise positioning of the tool in three-dimensional space, enabling adaptation to various work angles without compromising structural integrity or requiring complex mechanisms.
2Productivity
If ladders, cradles, or scaffolds are used to reach high areas, then workers can access elevated surfaces, but the equipment must be consistently moved and repositioned, resulting in time-consuming and inefficient work
Solution Approach 1:
The holder acts as an intermediary between the extension pole and the tool, providing a stable mounting platform that eliminates the need for ladders or scaffolds. By attaching the tool directly to the extension pole through this holder, workers can reach high areas without the need to move heavy support equipment, significantly reducing setup time and increasing productivity.
3Reliability
If ladders or scaffolds are used to reach high areas, then workers can access elevated surfaces, but the work conditions become highly insecure and potentially dangerous
Solution Approach 1:
The invention extracts the need for ladders, cradles, and scaffolds from the work system by using an extension pole with a holder that can be safely operated from ground level. This eliminates the primary source of danger—working at height on unstable platforms—while still enabling access to elevated surfaces for painting and maintenance tasks.
4Adaptability or versatility
If holders designed for specific predetermined angles are used, then the tool can be held at those specific angles, but the predetermined angles may not match the multiple angles required for different high areas or objects
Solution Approach 1:
The holder is designed as a universal mounting device that can accommodate tools at multiple angles along three axes (X-X, Y-Y, and Z-Z). This multi-functional capability allows the same holder structure to adapt to various work scenarios and surface orientations without requiring angle-specific designs, maintaining structural simplicity while providing extensive positioning flexibility.

AI summary
The invention is directed to an ergonomic tool holder, adaptable to a conventional pole and having a handle (14) and a supporting base (28). These are coupled to an interconnecting unit (21) 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 (11) 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.
