Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bit holders are prone to fasteners falling off, leading to lost time and potential component failure due to the fasteners becoming foreign objects in the work area.
Innovation Solution
A magnetic bit holder design featuring a ring magnet surrounding the axis of rotation, with a first connector secured to a tool and a solid shaft of non-ferrous material extending through the ring magnet, which holds a tool bit and secures fasteners via a magnetic field.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional bit holder is used, then the structure is simple, but fasteners fall off and become foreign objects
Solution Approach 1:
The patent replaces mechanical retention methods (screws, clips, or manual holding) with a magnetic field-based retention system. A ring magnet is integrated into the bit holder body, generating a magnetic field that automatically holds fasteners on the tool bit without additional mechanical fastening components, thus improving reliability while maintaining structural simplicity.
Solution Approach 2:
The magnetic field acts as an intermediary force between the bit holder and the fastener. The ring magnet creates this magnetic field that mediates the retention function, allowing fasteners to be held securely without direct mechanical contact or additional fastening mechanisms, thereby simplifying the overall structure.
2Productivity
If manual holding of fasteners is required, then the bit holder structure remains simple, but operational efficiency decreases and safety is compromised
Solution Approach 1:
The magnetic bit holder enables self-service fastener retention where the magnetic field automatically holds fasteners in place during tool operation. The system serves itself by using the magnetic field generated by the ring magnet to continuously retain fasteners without requiring external manual intervention, thereby improving operational efficiency and safety.
3Reliability
If fasteners become foreign objects, then lost time is minimized, but component failure risk increases
Solution Approach 1:
The magnetic retention system ensures that fasteners remain securely attached to the tool bit throughout operation, eliminating the risk of them becoming lost foreign objects. This reliable retention mechanism prevents component failure and eliminates the need for time-consuming searches for lost fasteners, thereby improving both safety and operational efficiency.

AI summary
A magnetic bit holder includes a ring magnet surrounding an axis of rotation of the magnetic bit holder. A first connector is fixed with respect to the ring magnet and positioned along the axis of rotation on a first side of the ring magnet. The first connector is operable to secure to a tool along the axis of rotation. A solid shaft of non-ferrous material extends through the ring magnet. A second connector is positioned along the axis of rotation on a second side of the ring magnet. The second connector is operable to hold a tool bit.
