Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools lack a standard handle and strap that provides ergonomic solutions and complete control without causing fatigue or repetitive strain injuries, and current gripping options are inadequate.
Innovation Solution
A universal handle system with a secure hook and loop strap and ergonomic design that can be adapted to various tools, featuring a palm rest, hand strap, and anti-rotation mechanism, along with an aluminum mount and adhesive tape for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a standard handle and strap system is implemented, then ergonomic comfort and control are improved, but compatibility with existing tools is limited
Solution Approach 1:
The handle system employs a universal mounting interface with a standardized threaded connection (5/16-18 male thread) that can attach to various tool types including drywall hawks, mud pans, and mixing boards. The aluminum mount block with adhesive backing provides a standardized attachment method that works across different tool surfaces and materials, making the ergonomic handle compatible with existing tools without requiring tool-specific designs
2Ease of operation
If a secure grip mechanism is used, then control is improved, but fatigue and repetitive strain injuries may occur
Solution Approach 1:
The handle incorporates a palm rest at the gripping area to distribute pressure and reduce strain on the hand. The curved edges of the palm rest provide increased comfort by conforming to the natural shape of the hand, while the hook and loop strap secures the handle to the back of the hand without excessive tightness. This localized ergonomic design provides secure control while preventing fatigue and repetitive strain injuries
3Strength
If the handle is directly attached to the tool, then connection strength is improved, but thermal transfer between tool and handle increases
Solution Approach 1:
The aluminum mount block serves as an intermediary component between the tool surface and the handle's threaded connection. The high bond double sided foam acrylic adhesive tape provides the bonding interface to the tool, while the threaded hole in the mount block accepts the handle's male thread. This intermediary mount block structure maintains strong connection while providing thermal separation between the tool and handle, reducing thermal transfer
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Provides ergonomic comfort and improved control for users, reducing fatigue and strain by allowing secure attachment to a variety of tools without altering their design.
Implementation Method 1
Body 24 is a high bond, double sided foam acrylic adhesive tape. It is attached to the block, with the second side of the adhesive attached to the tool.
Implementation Method 2
Body 12 is a webbing backing hook and loop strap adjustable in nature and for securing the handle firmly to the back of the hand.

AI summary
An adaptable handle and mount provided for the use with tools needing the assist of a handle. Handle is used in a horizontal fashion and offers the user a no grip solution. The handle comprises a palm rest that is intended to be positioned in your palm, having additional features for comfort. The handle also includes a hand strap that is fastened to the palm rest, its function is to secure the handle assembly firmly to the hand. Also consists of a connection point for attaching handle to the tool with a threaded bolt, nut, and push-on bolt retainer used for Anti-rotation and handle to tool alignment. Further comprised of a mount consisting of an aluminum block with female threads sized and shaped to allow for sufficient adhesion of a high bond, double sided, acrylic adhesive tape to accommodate original tools design.
