Solution Overview

Problem

Existing shopping carts do not facilitate easy and safe transportation of goods by allowing direct access without lifting them above the side walls, and they lack flexibility in handling different types of goods and space-saving folding.

Innovation Solution

A shopping cart with a pivotable side wall attached to a main frame, enabling goods to be picked up through a lateral opening without lifting, combined with a foldable design for compact storage and noise-dampening features.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If goods are placed in a shopping cart with fixed side walls, then the cart structure is simple and stable, but goods cannot be easily accessed without lifting them above the side walls

Engineering Contradiction:
Improveease of goods accessVSAvoidcart structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The side wall is made dynamically movable through a pivot mechanism attached to the main frame. The side wall can rotate between a closed position (providing containment) and an open position (providing access to goods). This dynamic element allows the cart to adapt its structure based on operational needs, resolving the contradiction between structural simplicity and ease of goods access.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The cart structure is segmented into fixed components (main frame, base, other side walls) and a movable component (one side wall). This segmentation allows the majority of the structure to remain simple and stable while only one segment provides the additional functionality of easy goods access, minimizing the overall complexity increase.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the shopping cart has a fixed design, then manufacturing is simple, but it lacks flexibility in handling different types of goods

Engineering Contradiction:
Improveflexibility in handling goodsVSAvoidmanufacturing simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The pivotable side wall mechanism provides adaptability for handling different types of goods. The side wall can be opened to accommodate various item sizes and shapes, and the mesh material allows visibility and ventilation for different product types. This single dynamic element adds versatility without requiring multiple specialized cart designs.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The pivotable side wall serves multiple functions: it provides easy access to goods, allows the cart to accommodate different item sizes and types, and maintains structural integrity when closed. This multi-functional element increases adaptability while adding minimal complexity to the manufacturing process.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Volume of moving object

If the shopping cart maintains a compact folded design, then storage space is reduced, but the structure becomes more complex

Engineering Contradiction:
Improvestorage volumeVSAvoidfolding mechanism complexity
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The side wall's pivot mechanism enables the cart to transition between expanded and folded states. When not in use, the side wall can be rotated to a folded position, reducing the cart's overall volume for compact storage. The same dynamic mechanism that provides goods access also enables space-saving folding, balancing reduced storage volume with acceptable structural complexity.

Inventive Principle:
Principle #15Dynamics

AI summary

The invention relates to a shopping cart for hand-guided rolling on a driving surface and for picking up and transporting goods with a wire basket having a pivoting side wall, such that by pivoting the pivoting side wall a lateral receiving opening on the wire basket is released through which goods can be picked up from the wire basket.
