Screwing Tool Torque Support with Adaptive Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Applying torque to screw connections using a screwdriver can be uncomfortable, tiring, and potentially injurious, especially for multiple connections or high torques, necessitating improved and simplified operation of screwing tool torque supports.
Innovation Solution
A screwing tool torque support designed with a fastening area for attachment to a screwing tool and a support area for surrounding support, featuring a two-part construction with a support foot and arm connected via a coupling area allowing relative movement, enabling adaptation to ambient conditions and compensating for misalignments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hand-held screwdriver is used to apply torque to screw connections, then the fitter can directly operate the tool, but the reaction torque must be applied by the fitter which is uncomfortable and tiring
Solution Approach 1:
The torque support device is divided into separate functional components: a support foot for contacting the workpiece, a support arm for positioning, and a coupling mechanism for attachment to the screwdriver. This segmentation allows the reaction torque to be distributed to the workpiece through the support foot rather than being borne entirely by the fitter's hand.
Solution Approach 2:
The torque support device acts as an intermediary between the screwdriver and the workpiece. It provides a stable support structure that contacts the workpiece directly, thereby mediating the reaction torque and preventing it from being transmitted to the fitter's hand while maintaining control over the screwdriver's operation.
2Ease of operation
If a screwdriver torque arm is used to support the housing, then the fitter does not have to apply reaction torque, but the device complexity increases
Solution Approach 1:
The coupling area between the support foot and support arm provides at least one degree of freedom for relative movement, making the torque support device dynamic rather than rigid. This allows the device to adapt automatically to variations in workpiece geometry and positioning, simplifying operation while maintaining support functionality without requiring complex adjustment mechanisms.
Solution Approach 2:
The degree of freedom in the coupling area enables automatic adjustment of the relative position and orientation between the support foot and support arm. This parameter change capability allows the device to adapt to different work conditions without increasing structural complexity, as the adjustment occurs passively through the inherent mobility of the coupling mechanism.
3Adaptability or versatility
If the support foot and support arm are connected rigidly, then the structure is stable, but adaptation to ambient conditions and compensation for misalignments is limited
Solution Approach 1:
The coupling area is designed with at least one degree of freedom that allows relative movement between the support foot and support arm. This dynamic connection maintains structural stability for torque support while enabling automatic adaptation to ambient conditions such as workpiece positioning variations and geometric tolerances.
Solution Approach 2:
The torque support device combines rigid components (support foot, support arm) with a flexible coupling mechanism. This composite structure integrates both stability and adaptability: the rigid parts provide structural integrity for torque transmission, while the coupling area with degrees of freedom provides adaptability to misalignments and ambient conditions.
