Shopping Trolley Pivoting Side Wall for Lateral Goods Access
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
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
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.
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.
3Volume of moving object
If the shopping cart maintains a compact folded design, then storage space is reduced, but the structure becomes more complex
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.

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.
