Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The existing chuck structures are operationally inconvenient and time-consuming due to the need to manually screw the pressing mechanism in opposite directions to clamp and release objects, leading to inefficiencies in clamping and unclamping processes.

Innovation Solution

A chuck structure featuring a first chuck with a sliding seat and a limiting element with one-way sawtooth stops, an operating element connected to a second chuck, and an elastic element to create a controlled accommodation space, allowing for single-direction rotation and adjustment of the clamping mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the pressing mechanism is screwed in opposite directions to clamp and release objects, then the clamping function is achieved, but the operation becomes inconvenient and time-consuming

Engineering Contradiction:

Improveclamping operation convenienceVSAvoidtime consumption for clamping and releasing

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent inverts the traditional threading direction of the pressing mechanism. The pressing mechanism uses left-handed threading instead of conventional right-handed threading, allowing the operator to push the handle forward to simultaneously achieve both clamping and releasing actions in opposite directions, thereby eliminating the need for reverse screwing operations

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent introduces a dynamic limiting element that can swing between locked and unlocked positions. When the limiting element is in the locked position, it prevents the operating element from rotating in the releasing direction. When pushed to the unlocked position, it allows bidirectional rotation. This dynamic mechanism enables quick switching between clamping and releasing modes without manual threading direction changes

Inventive Principle:

Principle #15Dynamics

2Productivity

If the operating element is restricted to single-direction rotation, then operational efficiency is improved, but the ability to adjust clamping space in both directions is limited

Engineering Contradiction:

Improveoperational efficiencyVSAvoidclamping space adjustment flexibility

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The limiting element is designed as a dynamic component that can change its state between locked and unlocked. In the locked state, it restricts rotation to one direction only, improving operational efficiency. When needed for adjustment, it can be pushed to unlock, allowing bidirectional rotation. This dynamic characteristic resolves the contradiction between efficiency and flexibility

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The elastic element acts as an intermediary between the operating element and the limiting element. It provides the necessary force to return the limiting element to its locked position after being pushed, and also provides cushioning during the unlocking process. This intermediary mechanism enables smooth transition between restricted and unrestricted rotation modes

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A chuck structure includes: a first chuck, provided with a seat slidable relatively thereto, the seat provided with a first stop; a limiting element, swingable relatively to the seat, and provided with a second chuck; and an operating element, respectively connected with the limiting element and a second chuck, and driving the second chuck to move relatively to the first chuck to form an accommodation space between the first chuck and second chuck, an elastic element configured between the operating element and limiting element, and the elastic element pressing against the limiting element to approach the seat, allowing the second and first stops to be in contact with each other. The present invention can use the operating element 3 to adjust the size of the accommodation space, and the second stop in contact with first stop to make the operating element can only be rotated in a single direction.
