Auxiliary Handle Perpendicular Grip for Power Tool Torque
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-held power tools lack effective solutions for safely and precisely managing torque and providing ergonomic handling, especially during varied working positions and high-torque applications.
Innovation Solution
The introduction of an additional grip element aligned perpendicularly to the machining axis, combined with a fastening unit that allows tool-free attachment and detachment, enhances grip security and adaptability, enabling comfortable and precise handling by allowing operators to easily switch between grip positions and reduce torsional forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single handle element is used, then the device complexity is low, but the ability to manage torque and provide ergonomic handling in varied working positions is insufficient
Solution Approach 1:
The handle is divided into multiple independent grip elements (first grip element integrated with housing, second grip element as separate auxiliary handle) that can be selectively used. This segmentation allows the operator to choose different grip positions depending on the working situation, thereby improving handling adaptability without significantly increasing overall device complexity.
Solution Approach 2:
The handle system is designed to serve multiple functions: the first grip element provides standard handling, while the second grip element enables alternative gripping positions for high-torque applications or restricted access scenarios. This multi-functionality allows a single handle system to adapt to various working conditions and operator needs.
2Ease of operation
If the grip elements are aligned parallel to the machining axis, then the handle structure is simple, but the operator's hand must be twisted and the view of the workpiece is obstructed
Solution Approach 1:
The second grip element is positioned perpendicular to the machining axis, creating a different spatial dimension for hand placement. This perpendicular arrangement allows the operator's hand to remain in a natural, untwisted position while providing an alternative gripping option that does not obstruct the view of the workpiece, thereby improving ergonomic comfort.
3Adaptability or versatility
If a fixed handle configuration is used, then the device complexity is low, but the adaptability to different working positions and torque requirements is limited
Solution Approach 1:
The handle system transitions from a static, fixed configuration to a dynamic, selectable configuration. The second grip element can be positioned at different locations along the housing, and the operator can switch between grip elements based on the working situation. This dynamic adaptability allows the handle system to respond to different torque requirements and working positions without requiring complex adjustment mechanisms.
