Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand tools for driving hex head screws face issues with clogging due to screw shavings and metal waste, requiring frequent cleaning and the need for multiple drivers for different sizes, which slows down the assembly process.
Innovation Solution
A cleanable reversible socket and driver tool combination with a hex or splined passage, featuring a magnetized socket end for holding fasteners and a spring-loaded detent for secure locking, allowing easy cleaning and size switching without tool replacement, compatible with various handle types and drill chucks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a magnet is placed in the socket to hold hex head fasteners, then the fastener holding capability is improved, but the socket becomes clogged with metal shavings and debris requiring frequent cleaning
Solution Approach 1:
The socket is divided into two separate hexagonal openings of different sizes within a single socket body, allowing the user to switch between different fastener sizes without changing sockets. This segmentation also creates separate magnetic zones for each opening, isolating debris accumulation to specific areas that can be independently cleaned.
Solution Approach 2:
The magnetized driver shaft is designed to be easily removable from the socket, allowing users to discard accumulated debris by removing the driver and cleaning the socket cavity. The magnet itself can be brushed off to remove debris, and the socket can be tapped to dislodge accumulated shavings, recovering the cleaning function without replacing entire components.
2Manufacturing precision
If multiple separate drivers are used for different sized hex head screws, then the precision for different fastener sizes is improved, but the device complexity and number of tools required increases
Solution Approach 1:
A single socket body incorporates two different sized hexagonal openings, allowing one socket to perform the function of two separate sockets. The magnetized driver shaft can be inserted into either opening depending on the fastener size required, making one tool universally applicable to multiple fastener sizes and eliminating the need for multiple specialized drivers.
Solution Approach 2:
Two separate socket functions (different sized hexagonal openings for different fastener sizes) are merged into a single integrated socket body. The magnetized driver shaft serves as a common interface for both openings, combining multiple tool functions into one unified device that reduces tool inventory while maintaining size-specific precision.
3Reliability
If the socket is made secure and releasably interlockable with the driver shaft, then the connection reliability is improved, but the ease of cleaning the socket is reduced
Solution Approach 1:
The connection between socket and driver shaft transitions from static to dynamic - the spring-loaded detent mechanism provides automatic engagement and secure locking during operation, but allows easy manual disengagement by applying slight axial force. This dynamic characteristic enables the connection to be both secure during use and easily removable for cleaning.
Solution Approach 2:
The locking function is extracted as a separate spring-loaded detent mechanism rather than being integrated into the main connection structure. This separate extraction of the locking function allows it to operate independently - providing secure engagement through the detent-ball-and- groove interaction while permitting easy removal by overcoming the spring force, thus maintaining both connection reliability and cleaning ease.

Function Achieved in This Case
Enables efficient assembly by allowing easy cleaning and size switching, reducing downtime due to clogging and eliminating the need for multiple drivers, while maintaining secure fastener holding and torque transmission.
Implementation Method 1
A magnet on the socket mounting end of the driver shank is to be located at a bottom of one of the two hex socket ends when the socket is mounted on the driver shank to hold the hex head fastener in one of the socket ends

AI summary
A cleanable reversible socket and driver for a hex head fastener having a driver shank with a hex shaped shaft, or otherwise splined, having a tool mounting end and a socket mounting end and a collar therebetween. A cleanable reversible socket is provided having a hex, or otherwise splined, passage therethrough rotationally lockable with the similarly shaped driver shank shaft. The socket is removably, nonrotatably mountable onto the driver shank shaft at the socket mounting end up to the collar having two different sized hex socket ends. A magnet on the socket mounting end of the driver shank is to be located at a bottom of one of the two hex socket ends when the socket is mounted on the driver shank to hold the hex head fastener in one of the socket ends.
