Solution Overview

Problem

Existing bottle holders for shopping carts require additional clamping parts for attachment to wire mesh structures, increasing manufacturing and assembly costs, and do not easily form bottle holder units.

Innovation Solution

A bottle holder design that uses snap-fit fastening means to attach directly to a wire mesh structure without additional fasteners, allowing for easy assembly into units by bridging dimensional tolerances with wider receiving areas for vertical lattice bars and utilizing connecting means for multiple holders.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If additional clamping parts and fasteners are used to attach the bottle holder to the wire mesh structure, then the attachment reliability is improved, but the device complexity and manufacturing costs increase

Engineering Contradiction:

Improveattachment reliabilityVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The fastening function is merged into the bottle holder body itself. The U-shaped design of the bottle holder allows it to encircle and attach directly to the wire mesh structure without requiring separate clamping parts or fasteners, thus reducing device complexity while maintaining attachment reliability

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The bottle holder performs its own fastening function through its U-shaped structure that can be placed around the wire mesh structure. The elastic element provides automatic tension to secure the attachment, eliminating the need for external fasteners or complex assembly mechanisms

Inventive Principle:

Principle #25Self-service

2Strength

If additional clamping parts and fasteners are used to attach the bottle holder, then the attachment strength is improved, but the manufacturing costs increase

Engineering Contradiction:

Improveattachment strengthVSAvoidmanufacturing costs

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The fastening function is integrated into the bottle holder body, eliminating the need for separate fasteners and clamping parts. This reduction in component count directly lowers manufacturing costs while the elastic element ensures sufficient attachment strength

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The design uses simple, inexpensive materials and structures. The elastic element is a basic mechanical component that provides sufficient strength at low cost, and the overall design prioritizes cost-effective manufacturing over using expensive fasteners

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Ease of manufacture

If a single wire or simple structure is used for the bottle holder, then the ease of manufacture is improved, but the ability to form stable bottle holder units decreases

Engineering Contradiction:

Improveease of manufactureVSAvoidstability of bottle holder unit

Core Design Contradiction:

Ease of manufactureVSStability of the object's composition

Solution Approach 1:

Multiple bottle holders are merged into a single integrated unit through connecting elements that join them together. This allows the formation of stable bottle holder units capable of holding multiple bottles, while each individual holder remains simple to manufacture

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The bottle holder design is universal and can be configured in different arrangements. The connecting elements allow multiple holders to be joined in various configurations, providing multi-functionality and adaptability while maintaining simple individual components

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Manufacturing precision

If fixed fastening positions are used, then the manufacturing precision is improved, but the adaptability to different wire mesh structures decreases

Engineering Contradiction:

Improvefastening position precisionVSAvoidadaptability to wire mesh structure

Core Design Contradiction:

Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The fastening system is designed to be dynamic and adjustable rather than fixed. The elastic element allows the bottle holder to adapt to different positions and dimensions of wire mesh structures, providing versatility while maintaining secure attachment through elastic tension

Inventive Principle:

Principle #15Dynamics
