Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an abutting element is disposed in the conventional socket to improve tool holding stability, then the stability of holding the tool is improved, but the difficulty of processing and manufacturing cost are increased due to the need to drill a through hole with a complicated shape
Solution Approach 1:
The abutting element is separated from the socket body and placed into a through hole, dividing the tool holding function into two independent components. This allows the through hole to be a simple circular shape that is easy to drill, while the abutting element provides the necessary tool retention force through its elastic deformation.
Solution Approach 2:
The abutting element acts as an intermediary component between the tool and the socket body. It transmits the holding force from the simple circular through hole structure to the tool, enabling stable tool retention without requiring the socket body itself to have a complex shape.
2Reliability
If an abutting element is disposed in the conventional socket to prevent tool detachment, then the reliability of tool retention is improved, but the manufacturing cost is increased
Solution Approach 1:
By separating the abutting element from the socket body and using a simple circular through hole, the manufacturing processes are simplified. The through hole can be drilled with standard equipment, and the abutting element can be manufactured independently, reducing overall manufacturing complexity and cost compared to integrating a complex abutting structure directly into the socket.
Solution Approach 2:
The abutting element is designed as a simple elastic component that can be easily manufactured and replaced if needed. This approach uses a relatively simple, potentially disposable component to achieve reliable tool retention, rather than requiring expensive, complex integrated structures in the socket body.
3Ease of manufacture
If a simple circular through hole is used instead of a complicated shape, then the ease of manufacture is improved, but the stability of the abutting element at the socket may be compromised
Solution Approach 1:
The abutting element is designed to be elastic and deformable, allowing it to dynamically adapt to the tool it holds. When the tool is inserted, the abutting element deforms elastically to conform to the tool's shape and size, creating a stable fit. This dynamic adaptation compensates for the simplicity of the circular through hole shape.
Solution Approach 2:
The elastic properties of the abutting element allow it to change its physical parameters (shape, volume) in response to the tool it holds. This parameter change enables the simple circular through hole to effectively retain various tools with different dimensions, maintaining stability without requiring a complex hole shape.

AI summary
A socket includes a body, a through hole, an accommodating base and an abutting element. The body includes an outer wall and an operating inner surface. The operating inner surface surrounds an operating space, and the operating space is configured for a tool to insert therein. The through hole penetrates the outer wall and the operating inner surface radially, and the through hole is communicated with the operating space. The accommodating base is accommodated in the through hole and includes a bottom portion and a surrounding wall. The bottom portion is located at an outer end of the through hole and covers the through hole. The surrounding wall is connected to the bottom portion and located in the through hole. The surrounding wall and the bottom portion surround an accommodating space. The abutting element is disposed in the accommodating space.
