Peep-hole Socket Driving Shank Modular Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional deep-hole socket driving shank assemblies suffer from poor circularity and non-coaxial alignment, leading to deflection during rotation, and are not modular, limiting their use with different nut sizes and specifications.
Innovation Solution
A driving shank assembly featuring a hollow tube with enlarged portions having external threads and elastic clamping pieces, allowing for quick release nuts to secure and release a drive head and connector, ensuring coaxial alignment and easy size adaptation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the tube and connecting member are formed integrally, then the structure is simplified and manufacturing is easier, but the driving head cannot be adapted to nuts of different sizes and specifications
Solution Approach 1:
The driving shank assembly is divided into separate modular components: the tube (10), drive head (20), connector (30), and quick release nuts (40). This segmentation allows the driving head to be easily detached and replaced to accommodate different nut sizes and specifications, while the tube maintains its structural integrity through the modular connection system.
Solution Approach 2:
The quick release nut mechanism enables dynamic reconfiguration of the assembly. The elastic clamping pieces (15) provide automatic locking when the quick release nut is tightened, and automatic release when the nut is removed, allowing rapid adaptation to different driving head configurations without complex assembly procedures.
2Device complexity
If the tube and connecting member are formed integrally, then the number of parts is reduced, but the components cannot be dismantled for size adaptation
Solution Approach 1:
The assembly is segmented into detachable modules connected through the tube's enlarged portions. The drive head and connector can be independently mounted and removed via the quick release nut mechanism, providing size adaptation capability while maintaining a relatively simple overall structure.
Solution Approach 2:
The tube (10) serves as a universal connector with enlarged portions that can accommodate different drive heads and connectors through the standardized quick release nut interface. This multi-functional design allows a single tube to support various configurations without requiring multiple specialized components.
3Ease of manufacture
If the tube and connecting member are not coaxial, then manufacturing alignment is easier, but the tube deflects easily during rotation
Solution Approach 1:
The elastic clamping pieces (15) automatically adjust to center and align the drive head (20) and connector (30) with the tube (10) during assembly. When the quick release nut is tightened, the elastic clamping pieces exert radial force that self-corrects any misalignment, ensuring coaxial positioning without requiring precision manufacturing or manual alignment procedures.
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
The solution enables stable, non-deflecting operation and easy size adaptation, facilitating quick and secure mounting and dismounting of the drive head and connector, enhancing usability and precision.
Implementation Method 1
Each of the enlarged portions has a periphery provided with a plurality of slits and a plurality of elastic clamping pieces between the slits. Each of the slits is connected to the mounting recess and extends axially along the tube.
