Tool Connector with Movable Collar for Dual Bit Seating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool connectors cannot accommodate both one-inch and two-inch hex bits efficiently, as they require different seating depths, leading to difficulties in bit removal and potential jamming, and existing solutions with multiple seating positions are complex and costly to manufacture.
Innovation Solution
A tool connector with a shaft and collar assembly that includes a magnetic mechanism and a ball detent locking mechanism, allowing for reciprocation between two seating positions to accommodate different bit sizes, ensuring easy engagement and release of both one-inch and two-inch bits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single tool connector is designed to accommodate both one-inch and two-inch hex bits, then the connector must provide multiple seating positions, but this increases device complexity and manufacturing cost
Solution Approach 1:
The connector employs a movable collar that can shift between two positions along the shaft. This dynamic element allows the connector to adapt its internal geometry to accommodate different bit sizes without requiring multiple fixed structures, thereby maintaining versatility while controlling complexity
Solution Approach 2:
The connector changes its effective seating depth parameter by moving the collar between two defined positions. This parameter adjustment enables the same connector structure to properly seat both one-inch and two-inch bits at appropriate depths, achieving adaptability without complex multi-configuration design
2Strength
If one-inch bits are seated at the deeper position required for two-inch bits, then torque transmission is improved, but the bits become difficult to grasp for removal and may jam in the connector
Solution Approach 1:
The movable collar dynamically adjusts the seating depth based on bit size. When a one-inch bit is inserted, the collar positions itself to provide shallower seating that maintains adequate torque transmission while leaving sufficient bit length exposed for easy grasping and removal, preventing jamming
Solution Approach 2:
The seating depth parameter is adjusted based on bit size: one-inch bits are seated at a shallower depth optimized for removal accessibility, while two-inch bits are seated deeper to maximize torque transmission. This parameter optimization resolves the contradiction between strength and ease of operation for different bit types
3Adaptability or versatility
If previously designed connectors use wire detent or ball bearing detent mechanisms with precision machining, then multiple seating positions are achieved, but manufacturing cost and complexity increase
Solution Approach 1:
The invention replaces complex mechanical detent mechanisms with a simpler movable collar system that achieves multiple seating positions through controlled displacement rather than precision-machined detents. This substitution maintains versatility while significantly simplifying manufacturing
Solution Approach 2:
The movable collar serves multiple functions: it enables both seating positions, provides the locking mechanism, and guides bit insertion. This multi-functionality eliminates the need for separate wire detents or ball bearing mechanisms, reducing manufacturing complexity and cost while maintaining adaptability

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The tool connector provides a cost-effective and user-friendly solution by allowing the use of both one-inch and two-inch bits without jamming, using magnetic force and a ball detent locking mechanism to securely hold and release bits in their respective positions.
Implementation Method 1
a magnet disposed within the shaft for magnetically engaging the first and second work tools when the first or second work tool is received within the shaft
Implementation Method 2
a ball detent locking mechanism for lockingly engaging at least one of the first and second work tools

AI summary
A tool connector generally includes a tool receiving portion configured for reciprocating between first and second work tool seating positions, wherein the tool receiving portion is normally biased to the first work tool seating position, and actuatable to the second work tool seating position. The tool connector further includes a magnetic mechanism in the tool receiving portion for providing magnetic force to engage a work tool in either of the first and second work tool seating positions, and a locking mechanism for lockingly engaging a work tool in the second work tool seating position.
