Anti-Slip Socket Geometry for Damaged Fastener Torque Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional wrench and wrench socket designs experience slippage due to wear and tear, corrosion, and damage to the fastener head, leading to inefficient torque transfer and the need for additional tools like bolt extractors.
Innovation Solution
The anti-slip torque tool incorporates grooves and serrations on the internal sidewalls of the socket to provide multiple gripping points, ensuring effective torque application on fastener heads, regardless of wear or damage, and is compatible with various tools and fastener types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wrench and socket designs are used, then the structure is simple and easy to manufacture, but slippage occurs due to wear, corrosion, and damage to the fastener head
Solution Approach 1:
The socket internal surface is equipped with grooves and serrations at specific locations rather than being uniformly textured. The grooves are positioned to engage with the fastener head corners, while serrations provide additional gripping points on the flat surfaces, creating localized high-grip zones that address wear and damage at critical contact points
Solution Approach 2:
The gripping surface is divided into multiple functional elements: grooves that segment the contact areas to engage corner regions, and serrations that further subdivide the gripping surface into multiple tooth-like contact points. This segmentation allows the tool to maintain grip even when individual contact points wear or become damaged
2Productivity
If traditional wrench designs are used, then the device is simple, but torque transfer is inefficient due to slippage
Solution Approach 1:
The grooves and serrations are strategically positioned on the socket internal surface to maximize torque transfer. The grooves engage the corner regions of the fastener head where structural integrity is highest, while serrations provide additional friction and mechanical interlocking on the flat surfaces, ensuring efficient torque transfer even when corners show signs of wear
Solution Approach 2:
The grooves and serrations are pre-formed on the socket internal surface before use, creating predetermined high-friction contact zones. This preliminary structuring of the gripping surface ensures that when torque is applied, the force is immediately directed through multiple engagement points rather than relying on smooth surface friction alone
3Reliability
If traditional socket designs are used, then manufacturing is simple, but the tool slips on damaged or worn fastener heads
Solution Approach 1:
Rather than texturing the entire internal surface, grooves are cut or formed at specific locations corresponding to fastener head corners, and serrations are added only on the flat contact surfaces. This localized approach provides enhanced grip where needed while minimizing additional manufacturing complexity
Solution Approach 2:
The gripping surface is segmented into grooves and serrations that can be manufactured as separate features and then combined. The grooves provide structural engagement points, while the serrations add friction surfaces, allowing the manufacturing process to address each feature's optimal creation method independently
