Modular Peep-hole Socket Driving Shank Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional deep-hole socket driving shank assemblies suffer from poor circularity between the tube and connecting member, leading to deflection during rotation, and are not modular, resulting in material waste and increased maintenance costs when components wear out or break.
Innovation Solution
A driving shank assembly with a tube, drive head, and connector that are coaxial and have precise circularity, allowing for detachable assembly with quick-release nuts and fastening caps, enabling use with different sizes and specifications, and allowing for replacement of individual components rather than the entire assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the tube and connecting member are formed integrally, then the structural strength is improved, but the adaptability for different nut sizes and specifications deteriorates
Solution Approach 1:
The driving shank assembly is divided into separate modular components: the tube, the drive head, and the connector can be detached from each other. This segmentation allows individual components to be replaced or adjusted based on specific application requirements, enabling adaptability to different nut sizes while maintaining structural integrity when assembled.
Solution Approach 2:
The tube is designed with universal mounting portions that can accommodate different types of drive heads and connectors. The standardized interface allows a single tube to work with multiple specifications of nuts, achieving multi-functionality and versatility across different fastening applications.
2Ease of manufacture
If the tube and connecting member are formed integrally, then the manufacturing simplicity is improved, but the ease of repair deteriorates
Solution Approach 1:
By segmenting the assembly into detachable components (tube, drive head, connector), the design enables selective replacement of only the worn or damaged part rather than the entire assembly. This significantly improves ease of repair while the modular design with standardized interfaces keeps manufacturing relatively simple.
Solution Approach 2:
The modular design allows the drive head or connector to be discarded and replaced independently when worn out, while the tube can be retained and reused. This recovering of functional components reduces maintenance costs and improves repair efficiency.
3Device complexity
If the tube and connecting member are formed integrally, then the device complexity is reduced, but the adaptability for different specifications deteriorates
Solution Approach 1:
The segmented modular design with standardized mounting portions actually simplifies the overall system complexity by allowing components to be independently manufactured and assembled. Different specifications can be achieved by simply changing the drive head or connector while keeping the tube the same, rather than creating entirely different integrated assemblies for each specification.
Solution Approach 2:
The universal mounting portions on the tube create a standardized interface that works across different specifications. This universality reduces device complexity by using a common base component (tube) that can accommodate various drive heads and connectors for different nut sizes and types.
4Ease of manufacture
If the tube and connecting member have poor circularity, then the manufacturing cost is reduced, but the stability during rotation deteriorates
Solution Approach 1:
The tube is designed with localized high-precision circularity at the mounting portions where the drive head and connector interface with the tube. This local quality ensures stable rotation and proper alignment at critical interfaces, while other portions of the tube can have standard manufacturing tolerances, balancing manufacturing cost with rotational stability.

AI summary
A driving shank assembly includes a tube, a drive head, a connector, two quick release nuts, and two fastening caps. The tube has two mounting portions each provided with a mounting recess for mounting the drive head and the connector respectively. The two quick release nuts are locked onto the two mounting portions of the tube respectively. The two fastening caps are locked onto the two quick release nuts respectively. Each of the two fastening caps has interior provided with an inner stepped edge. The drive head is provided with a stepped positioning edge abutting the inner stepped edge of one of the two fastening caps. The connector is provided with a stepped positioning edge abutting the inner stepped edge of the other one of the two fastening caps.
