Solution Overview

Problem

Existing carts require cumbersome lifting of goods or children over the side face due to fixedly connected sides, making loading and unloading inconvenient.

Innovation Solution

A cart design with detachable side-brackets that can be flipped open laterally, allowing easy access to the storage chamber and featuring folding and unfolding mechanisms for enhanced usability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the side face of the cart is fixedly connected, then the structural stability is improved, but the ease of operation deteriorates due to cumbersome loading requiring lifting over the side face

Engineering Contradiction:
Improvestructural stabilityVSAvoidease of loading
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The side face of the cart is divided into multiple detachable side-brackets that can be separated from the main frame. Each side-bracket is connected through a detachable connection mechanism, allowing the side face to be segmented into independent modules that can be removed or repositioned to facilitate easier loading and unloading of goods or children.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the side-bracket is detachably connected, then the ease of operation is improved by enabling lateral opening, but the device complexity increases due to additional connection mechanisms

Engineering Contradiction:
Improveease of loadingVSAvoidconnection mechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The side-bracket connection mechanism is designed to be dynamically changeable between locked and unlocked states. The detachable connection allows the side-bracket to transition from a fixed connected state to a removable state, providing dynamic adaptability that simplifies operation while managing complexity through standardized connection interfaces.

Inventive Principle:
Principle #15Dynamics

AI summary

A cart capable of being laterally opened comprises a cart body, which comprises a main frame and a first side-bracket arranged on one side of the main frame, wherein a storage chamber is formed between the main frame and the first side-bracket. The first side-bracket is detachably connected to the main frame, when the first side-bracket is disconnected from the main frame, an upper end of the first side-bracket is flipped downward relative to a lower end toward a direction away from the storage chamber, thus to form a first side-opening communicated with the storage chamber at one side of the main frame. When goods or children need to be placed into the cart, the first side-bracket can be disconnected from the main frame, and then the goods or children can be placed into the storage chamber from the first side-opening, so its usage is more effort-saving and convenient.
