Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sockets are prone to cracking under repeated impact and collision with fasteners, leading to insufficient tightening torque, potential worker injury, and frequent replacements, resulting in increased costs.
Innovation Solution
A socket design featuring a metal body with a conical section and a metal reinforcing sleeve of greater hardness, mounted around the conical section to enhance strength, with a deformation section and engagement portion for secure coupling, ensuring the socket's structural integrity and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a socket is made with a fastener receiving recess, then it can perform tightening or loosening operations, but the recess is liable to crack in corners due to repeated impact and collision with fasteners
Solution Approach 1:
The socket is divided into two distinct parts: the body (containing the fastener receiving recess) and the reinforcing sleeve (a separate protective component). The reinforcing sleeve is fitted over the body to specifically protect the vulnerable corners of the recess, allowing the socket to maintain its operational functionality while significantly improving crack resistance through this segmented structural approach.
2Strength
If the socket material is made stronger to prevent cracking, then the strength increases, but the cost increases and the size increases
Solution Approach 1:
The socket employs a composite structure consisting of the body made from standard socket material and the reinforcing sleeve made from high-strength material with greater hardness. This composite approach allows the vulnerable areas to be reinforced with superior material properties without requiring the entire socket to be made from expensive high-strength material, thus achieving enhanced crack resistance while controlling manufacturing costs.
3Strength
If the socket is made with larger dimensions to increase strength, then the strength increases, but the weight increases and the size increases
Solution Approach 1:
Instead of uniformly increasing the size and weight of the entire socket to improve strength, the reinforcing sleeve is designed to provide localized reinforcement only at the vulnerable corners and edges of the fastener receiving recess. This local quality approach concentrates the additional strength where it is most needed, preventing cracking in critical areas without unnecessarily increasing the overall dimensions and weight of the socket.
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 reinforced socket design significantly increases strength, reduces deformation, and extends service life by maintaining functionality even if the actuating hole cracks, while allowing for lower-cost, high-strength body materials and reduced size and weight.
Implementation Method 1
The reinforcing sleeve has a hardness greater than a hardness of the body
Implementation Method 2
The conical section has increasing diameters perpendicular to the longitudinal axis away from the second coupling end

AI summary
A socket (10) includes a body (20) and a reinforcing sleeve (30). The body (20) includes first and second coupling ends (21, 22) for respectively coupling with a fastener and a driving tool. The first coupling end (201) includes a conical section (26) having a small diameter end (261) and a large diameter end (262). A spacing between the small diameter end (261) and the second coupling end (202) along the longitudinal axis is smaller than a spacing between the large diameter end (262) and the second coupling end (202) along the longitudinal axis. The conical section (26) has increasing diameters perpendicular to the longitudinal axis away from the second coupling end (202). The reinforcing sleeve (30) is mounted around the conical section (26) of the body (20) to reinforce the socket (10).
