Solution Overview

Problem

Existing shopping baskets lack a simple, easy-to-assemble design made of plastic with integrated advertising capabilities and efficient storage and transportation features, particularly in self-service premises.

Innovation Solution

A plastic basket with a truncated rectangular base, featuring castors and a telescopic arm for easy rolling and storage, along with a dedicated space for advertisements using 'Hot printing' and 'In-mould labelling' techniques, allowing for easy assembly without additional fastening elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional plastic basket with U-shaped traction handle is used, then the basket can be rolled and towed, but the handle requires complex folding mechanisms and additional fastening elements for assembly

Engineering Contradiction:

Improverolling and towing capabilityVSAvoidhandle folding mechanism and assembly complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent removes the complex U-shaped folding handle mechanism entirely, extracting only the essential rolling function through a simple telescopic arm that deploys from the basket body. This eliminates the need for hinges, folding mechanisms, and multiple fastening elements while maintaining the core rolling capability.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The telescopic arm is divided into segments that can extend and retract, allowing the grasping means to deploy only when needed for rolling. This segmentation enables a simpler structure compared to a permanent U-shaped handle, reducing assembly complexity while maintaining operational functionality.

Inventive Principle:

Principle #1Segmentation

2Device complexity

If a basket design without integrated advertising space is used, then the structure remains simple, but advertising capabilities are lost

Engineering Contradiction:

Improvestructural simplicityVSAvoidadvertising display capability

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The basket body is designed to serve multiple functions: it provides structural containment for goods, supports the telescopic arm mechanism, and includes an integrated advertising space. This multi-functionality allows the advertising feature to be added without requiring a completely separate structure, maintaining overall simplicity while enabling marketing capabilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Strength

If a basket requiring screws or additional fastening elements for assembly is used, then structural strength is improved, but ease of manufacture and assembly is reduced

Engineering Contradiction:

Improvestructural strengthVSAvoidassembly simplicity without fastening elements

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The telescopic arm is merged with the basket body through direct integration, where the arm deploys from a predetermined location in the body without requiring separate fastening elements. This merging maintains structural strength through the integrated design while eliminating the need for screws or additional fastening elements, simplifying both manufacture and assembly.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

The invention relates to a basket, in particular, intended for storing and transporting goods in shops and other selling premises. The basket is formed of a body, including a bottom wall and four lateral walls, castors, and a grasping mechanism. The casters enable the basket to move by rolling over the ground. According to the invention, the grasping mechanism is a telescopic arm deploying from one of the walls of the body of the basket, the one wall being called the proximal wall.
