Torque-Resisting Hand Drill Support with Counterweight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for supporting hand drills are either cumbersome or require complex anchoring systems, making overhead drilling physically demanding and inefficient.
Innovation Solution
A device comprising a body support, a support rod, and a drill holder with a form-fitting recess for the hand drill, allowing for easy attachment and detachment without additional connecting elements, and featuring a length adjustment and torsion freewheel mechanism for improved usability and torque transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing drill supports are used, then the drill can be supported on the floor or with anchoring systems, but the device becomes cumbersome and physically demanding
Solution Approach 1:
The patent extracts the essential support function from complex anchoring systems and floor-supported devices. By removing unnecessary components and focusing only on the critical support mechanism, the device achieves overhead drilling capability without cumbersome anchoring systems, directly resolving the contradiction between ease of operation and device complexity
Solution Approach 2:
The support device is designed to be universally applicable to different hand drill types through standardized mounting interfaces. The single device can serve multiple functions: supporting overhead drilling, providing torque reaction absorption, and enabling precise positioning, thereby simplifying the overall system while maintaining operational ease
2Power
If heavy hand drilling machines are used, then drilling capability is improved, but physical effort and difficulty in aiming increase
Solution Approach 1:
The support device acts as a counterbalancing mechanism that absorbs the weight and torque reaction of heavy hand drilling machines. By providing a stable support structure that opposes the downward and rotational forces, the device enables users to operate powerful drills without experiencing excessive physical effort or difficulty in maintaining aim
Solution Approach 2:
The device creates a balanced operational state where the support structure equalizes the forces involved in overhead drilling. By positioning the support point and adjusting the leverage arms, the system achieves equipotentiality in terms of force distribution, making heavy drills as easy to aim and handle as lighter equipment

AI summary
The invention relates to a device for supporting and holding a hand drill. The device comprises: a body support; a support rod, wherein a longitudinal axis of the device extends in the longitudinal direction of the support rod; and a drill holder, wherein the body support is connected to the drill holder via the support rod, and the drill holder has a recess. The drill holder is designed for the positive-locking and rotationally fixed reception of a rear section of a hand drill, in order to hold the hand drill exclusively by its rear section in the drill holder, wherein the hand drill is arranged with its axis of rotation approximately parallel to the longitudinal axis.
