Geared Clickless Socket Wrench Infinitesimal Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing socket wrenches provide fixed incremental rotations, which are not precise enough for certain applications, lacking the ability for continuous rotation in infinitesimally small incremental steps.
Innovation Solution
A geared rotating socket wrench with a handle, rotating driver head, and a lever system that allows for infinitesimally small incremental rotations by using a first and second rotating gear with fixed small gears to prevent rotation in unintended directions, enabling continuous rotation in desired incremental steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a traditional click mechanism is used in the socket wrench, then the wrench provides fixed incremental rotations, but the rotation precision is insufficient for certain applications
Solution Approach 1:
The patent replaces the traditional click mechanism with a gear system that translates linear handle movement into rotational socket movement. This substitution eliminates the clicking mechanism while achieving precise rotational control through gear tooth engagement, where each handle movement produces a predetermined precise rotation of the socket.
2Adaptability or versatility
If a click mechanism with fixed incremental rotations is used, then the structure is simpler, but the ability to achieve continuous rotation in infinitesimally small incremental steps is lost
Solution Approach 1:
The gear system acts as an intermediary between the linear handle movement and the rotational socket movement. The gears translate and control the motion, allowing precise incremental rotations without requiring a complex click mechanism. Each gear tooth engagement provides a controlled incremental step, enabling continuous rotation control.
3Manufacturing precision
If the socket rotates a fixed amount for each click, then the mechanism is simpler to operate, but the precision for certain tightening applications is inadequate
Solution Approach 1:
The gear system segments the rotation into precise incremental steps corresponding to gear tooth engagements. Each handle movement is segmented into controlled rotational increments, providing precise tightening control while maintaining operational simplicity through the direct gear transmission mechanism.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables precise and continuous rotation of the socket, allowing for more accurate tightening and loosening of bolts and nuts without the limitations of fixed incremental movements.
Implementation Method 1
a first rotating gear with a plurality of teeth disposed on its perimeter connected by a first shaft to the rotating driver head; a second rotating gear with a plurality of teeth disposed on its perimeter mounted to a second shaft on the handle wherein the teeth on the first gear rotatingly mate with the teeth on the second gear
Implementation Method 2
two third gears fixed to the handle mounted laterally to the second rotating gear wherein the third gears engage the second gear if the user attempts to rotate the socket in a direction not selected and thereby preventing the driver head from rotating in a direction not selected by the lever
