Solution Overview

Problem

Conventional socket holders fail to securely retain sockets due to the retractable ball member being easily disengaged by external forces, leading to insufficient security and easy disconnection.

Innovation Solution

A socket holder design featuring a driving portion with a receiving room and a base member having a shaft with large and small diameter portions, allowing the blocking member to move between these portions for secure engagement and quick release, utilizing a radially movable blocking member that is abutted against the shaft and socket for locking and unlocking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a retractable ball member urged by an elastic member is used to secure the socket, then the socket holder structure is simple, but the socket cannot be sufficiently secured and is easy to disengage due to external force

Engineering Contradiction:
Improvesocket securityVSAvoidblocking structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The blocking member is divided into two distinct diameter portions: a large-diameter portion for secure blocking engagement and a small-diameter portion for easy disengagement. This segmentation allows the single blocking member to provide both strong retention and simple release mechanisms, resolving the contradiction between security and simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The blocking member is designed to be radially movable relative to the driving portion, transitioning between different positions (blocked and disengaged) based on the interaction with the shaft portion. This dynamic capability allows the structure to adapt between secure locking and easy release states without complex mechanisms.

Inventive Principle:
Principle #15Dynamics

2Reliability

If a single ball member is used for blocking, then the device structure is simple, but the socket is easy to disengage from the socket holder

Engineering Contradiction:
Improvesocket retentionVSAvoidengagement and disengagement ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The blocking member is segmented into large-diameter and small-diameter portions that interact differently with the shaft portion. The large-diameter portion provides reliable retention during normal operation, while the small-diameter portion enables easy disengagement when needed, thus improving both reliability and ease of operation simultaneously.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The blocking member utilizes changes in its radial dimension (diameter) to achieve different functional states. By varying the diameter along its length, it can provide strong blocking force in one section while allowing easy passage in another, resolving the contradiction between secure retention and easy operation.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If the blocking member is radially movable, then engagement and disengagement can be achieved, but the structure becomes more complex compared to a fixed blocking structure

Engineering Contradiction:
Improvequick release capabilityVSAvoidblocking member structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The blocking member combines multiple functions (secure blocking, easy release, and radial movement) into a single integrated component. This merging eliminates the need for separate mechanisms for each function, achieving quick release capability without significantly increasing overall structural complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The blocking member incorporates radial movability as an inherent dynamic characteristic rather than requiring additional actuating mechanisms. This dynamic design allows the blocking member to automatically transition between blocked and disengaged states through simple radial movement, achieving ease of operation with minimal added complexity.

Inventive Principle:
Principle #15Dynamics

AI summary

A socket holder is provided, including: an assembling member, including a driving portion which includes a receiving room and a blocking member which is disposed on and radially movable; a base member, including a shaft portion inserted in the receiving room and defining an axis, the shaft portion including a large-diameter portion and small-diameter portion, a diametric size of the large-diameter portion being larger than a diametric size of the small-diameter portion; wherein the driving portion and the base member are relatively movable so that the blocking member is relatively movable between the large-diameter portion and the small-diameter portion, when the large-diameter portion abuts against the blocking member, the blocking member is abutted against and between the shaft portion and the socket; when the small-diameter portion spatially corresponds to the blocking member, the blocking member is radially retractable inwardly between the shaft portion and the socket.
