Drive Bit With Longitudinal Slot For Eyebolts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools for installing eyebolts and cup hooks are cumbersome, require manual turning, and are not adaptable for varying sizes, making the process time-consuming and difficult, especially when dealing with multiple fasteners at different angles or elevations.
Innovation Solution
A socket tool with a drive bit featuring a hexagonal shank and a centrally located longitudinal slot that accommodates various sizes of eyebolts and cup hooks, allowing for easy installation using a power tool without pre-drilling, and enabling adjustable angle installation by seating into a power drill's chuck or manual driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual turning is used to install eyebolts and cup hooks, then the installation process can be performed without specialized tools, but the process becomes time-consuming and causes user fatigue
Solution Approach 1:
The patent replaces the manual mechanical turning operation with a power-driven rotational system. The drive bit interfaces with power tools (drills, impact drivers) to automatically rotate and drive eyebolts and cup hooks into surfaces, eliminating the need for manual hand-turning while maintaining ease of use through standardized tool interfaces.
Solution Approach 2:
The drive bit design enables self-contained operation where the tool assembly (drive bit + power tool) performs the complete installation function without requiring separate pre-drilling or manual positioning operations. The integrated design allows the system to self-adjust and self-drive the fastener in a single continuous motion.
2Manufacturing precision
If dedicated adaptors are used for specific eyebolt sizes, then precise fit is achieved, but the device complexity increases and assembly becomes time-consuming
Solution Approach 1:
The drive bit incorporates a universal gripping mechanism with adjustable or interchangeable gripping elements that can accommodate multiple eyebolt and cup hook sizes within a single tool design. This eliminates the need for multiple dedicated adaptors while maintaining precise fit through standardized interface geometries and adjustable gripping components.
Solution Approach 2:
The drive bit design incorporates dynamic or adjustable gripping elements that can adapt to different fastener sizes and geometries. The gripping mechanism may include movable jaws, adjustable clamps, or elastic elements that conform to the specific fastener being installed, providing precise fit without requiring complex dedicated adaptors for each size.
3Ease of operation
If pre-drilling is performed before installation, then the installation process becomes easier for hard surfaces, but the process becomes more time-consuming
Solution Approach 1:
The drive bit design incorporates preliminary action by integrating the drilling and fastening operations into a single unified process. The tool may include integrated cutting elements or pilot features that automatically prepare the hole and drive the fastener in one continuous motion, eliminating the separate pre-drilling step while maintaining ease of operation on various surface types.

AI summary
A drive bit used with a drill for installing a small diameter shanked cup hook or eyebolt into a stationary surface. The drive bit includes a tubular member integrally joined to the shaft. The shaft has a hexagonal cross-section shaped shank and includes a detent for insertion of the grip end into the chuck of a power tool, or the socket of a manual driver. The tubular member has opposite forward and rear ends and a central axis of rotation extending through the ends. The tubular member has at least one longitudinal extending from near the rear end through said forward end of said tubular member, said slot being sized to accept a fastener. The length of the slot is predetermined to allow the selection of a variety of shanked cup hooks or small eyebolts.
