Solution Overview

Problem

Existing carrying devices can only clamp goods boxes of fixed sizes, limiting their application scope and causing larger distances between adjacent boxes, especially when handling smaller items.

Innovation Solution

A goods taking mechanism with movable clamping plates that adjust to different sizes, allowing for wider application and reducing the distance between adjacent objects by using a driving assembly to move the clamping plates relative to a fixed member.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fixed-size clamping arms are used, then the structure is simple, but the application scope is limited and the distance between adjacent goods boxes increases

Engineering Contradiction:
Improveapplication scopeVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The clamping arms are designed with movable joints and driving assemblies that enable them to change their spacing dynamically. The first and second clamping arms can move relative to each other along the transportation direction, allowing the device to adapt to different goods box sizes while maintaining a relatively compact base structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The clamping mechanism is divided into multiple independent segments - the first clamping arm, second clamping arm, and connecting components. This segmentation allows each part to move independently, enabling the overall structure to adjust its configuration for different cargo dimensions without requiring complete structural redesign.

Inventive Principle:
Principle #1Segmentation

2Length of moving object

If fixed-size clamping arms are used, then the manufacturing is simple, but the distance between adjacent goods boxes becomes larger

Engineering Contradiction:
Improvedistance between adjacent goods boxesVSAvoidmanufacturing complexity
Core Design Contradiction:
Length of moving objectVSEase of manufacture

Solution Approach 1:

The clamping arms incorporate movable connections and driving mechanisms that allow real-time adjustment of the distance between adjacent clamping points. This dynamic adjustment capability enables the device to minimize the distance between goods boxes during transportation, optimizing space utilization without requiring overly complex fixed structures.

Inventive Principle:
Principle #15Dynamics

3Productivity

If clamping arms extend into large distances, then fixed-size boxes can be clamped, but the space efficiency decreases

Engineering Contradiction:
Improvestorage efficiencyVSAvoiddistance between clamping points
Core Design Contradiction:
ProductivityVSLength of stationary object

Solution Approach 1:

The driving assembly actuates the first and second clamping arms to move closer together when handling smaller goods boxes, and farther apart for larger boxes. This dynamic positioning optimizes the use of available space on the carrying device, improving storage efficiency by reducing unnecessary gaps between clamped objects while maintaining the ability to handle various box sizes.

Inventive Principle:
Principle #15Dynamics

AI summary

The present disclosure provides a goods taking mechanism and a carrying device. The goods taking mechanism includes a fixed member, a first clamping plate, a second clamping plate, and a driving assembly, where the first clamping plate and the second clamping plate are oppositely mounted on the fixed member and are connected to the driving assembly, and the first clamping plate and the second clamping plate are movable relative to the fixed member under the action of the driving assembly, to act on two opposing sides of a to-be-moved object. The goods taking mechanism of the present disclosure can clamp to-be-moved objects of different sizes, which helps reduce the distance between the adjacent to-be-moved objects.
