Rolling-Element Tool Bit Connector for Drop-Free Swapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tool part attachment systems face challenges such as tool bits being easily dropped during changes and difficult storage, especially when multiple tools are needed for various fastener heads.
Innovation Solution
A tool part attachment assembly featuring a connector with rolling elements and a bungee cord or metallic wire, allowing tool bits to be securely retained and easily swapped without tools, with the connector's design preventing accidental dropping and facilitating storage by hanging from the tool's handle grip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If tool bits are removably connected to the tool using conventional chuck methods, then the tool can accommodate various fastener heads and drill bits, but the tool bits can be easily dropped during the changing process and storage becomes difficult
Solution Approach 1:
The attachment assembly is divided into separate components: a connector that attaches to the tool bit, a retaining structure with rolling elements, and a magnetic retention mechanism. This segmentation allows the tool bit to be securely held while enabling easy detachment and storage of individual bits without dropping them during the changing process
Solution Approach 2:
The connector acts as an intermediary between the tool bit and the tool, providing a secure attachment mechanism with rolling elements and magnetic retention. This intermediary structure prevents the tool bit from being dropped during changing while maintaining the ability to accommodate various fastener heads and drill bits
2Adaptability or versatility
If tool bits are removably connected to the tool using conventional chuck methods, then the tool can accommodate various fastener heads and drill bits, but storage of tool bits after removal becomes difficult
Solution Approach 1:
The connector serves as an intermediary that provides an integrated storage solution. The retaining structure with rolling elements and magnetic retention mechanism allows tool bits to be securely stored in the connector itself or easily carried along with the tool, eliminating the need for separate storage containers and making bit storage convenient and organized
3Reliability
If a connector with rolling elements is used to retain tool bits, then tool bit retention security is improved, but the device complexity increases
Solution Approach 1:
The rolling elements in the retaining structure automatically engage with the tool bit to provide secure retention. The magnetic mechanism self-activates to hold the tool bit in place without requiring additional fastening actions, providing reliable retention while keeping the structure relatively simple and easy to operate

AI summary
A tool part attachment assembly for a tool is disclosed. The tool part attachment assembly has a tool part connector and a line. The tool part connector, which is configured for selectively retaining a tool part, has first and second parts and rolling elements disposed radially therebetween. The first part defines a connecting aperture configured to receive a portion of the tool part, is rotationally fixed relative to the tool part when the tool part is received in the connecting aperture, and is disposed inside the second part. The second part is rotationally connected to the first part. The line has a first end connected to the tool part connector, and a second end. In response to the tool part rotating, the first part rotates with the tool part relative to the second part. A tool part connector and a tool assembly are also disclosed.
