Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sockets are prone to deformation or breakage due to repeated contact and collision with bolts, leading to increased costs and reduced lifespan.
Innovation Solution
A socket design featuring a ring on the driving end with a rib and groove structure that enhances stress-bearing capacity by increasing the bonding area and preventing detachment during operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the socket structure is simplified for ease of manufacture, then manufacturing cost is reduced, but the stress-bearing capacity and strength are insufficient leading to deformation or breakage
Solution Approach 1:
The socket is divided into two separate components: a body and a ring. The ring is fitted onto the body to form an integrated structure. This segmentation allows each component to be manufactured separately with optimized structures, then assembled together to achieve higher overall strength without excessively complicating the manufacturing process of individual parts.
Solution Approach 2:
The socket combines two different components (body and ring) made from suitable materials to form a composite structure. The ring, in particular, is designed with high strength properties to reinforce the connection section, creating a composite structure that achieves superior stress-bearing capacity while maintaining manufacturing feasibility.
2Reliability
If the socket structure is reinforced to prevent deformation or breakage, then strength is improved, but the structural complexity and manufacturing difficulty increase
Solution Approach 1:
By segmenting the socket into body and ring components, the reinforcement is achieved through a separate ring structure that can be manufactured independently using standard processes, then assembled. This avoids the need for complex monolithic structures while achieving the desired reliability.
Solution Approach 2:
The ring is fitted onto the body in a nested configuration, where the ring surrounds and reinforces the connection section of the body. This nesting approach allows the reinforcement structure to be integrated without adding external complexity, as the ring becomes part of the overall socket structure through interference fitting.
3Strength
If a ring is added to enhance stress-bearing capacity, then the bonding area is increased, but the device complexity increases
Solution Approach 1:
The ring is nested onto the body through interference fitting, creating a compact integrated structure. This nesting approach maximizes the bonding area between the ring and body connection section while keeping the overall structure compact. The interference fit ensures large contact area for stress distribution without requiring additional complex fastening mechanisms.
Solution Approach 2:
The ring adds a circumferential dimension to the reinforcement strategy. Instead of merely thickening the body in radial directions, the ring provides reinforcement around the entire connection section, increasing the effective bonding area in the circumferential direction and distributing stresses more uniformly across the connection interface.

AI summary
A socket includes a body having a first driving end and a second driving end. A connection section is formed in an outer periphery of the second driving end and has a rib projecting from an inner bottom thereof. The rib includes a curved and protruded surface. A ring is engaged with the connection section of the body and includes an inner surface which has groove corresponding to the rib of the body. A bottom surface of the groove is a concave arc surface. When the ring is engaged with the connection section, the rib is engaged with groove to enhance a tightness between the body and the ring, and a bonding area between the connection section of the body and the ring is increased, thereby increasing a stress-bearing capacity of the connection section of the body.
