Solution Overview

Problem

Existing containers lack the ability to have interchangeable and detachable handles and straps, limiting user flexibility and adaptability in different scenarios.

Innovation Solution

The container assembly features a detachable and interchangeable system using buckle connectors, allowing for the attachment and detachment of straps and rigid handles, enabling users to customize their container according to specific needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If containers have fixed non-detachable handles and straps, then manufacturing is simpler and structure is more stable, but user flexibility and adaptability are reduced

Engineering Contradiction:

Improveuser flexibilityVSAvoidattachment system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The container attachment system is divided into separate modular components: the container body with integrated buckle connectors, and detachable handles/straps with complementary buckle connectors. This segmentation allows users to mix and match different attachment types while maintaining structural integrity through standardized connection interfaces.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The buckle connector design provides universal compatibility across multiple attachment types. The same buckle connector interface on the container body can accommodate both rigid handles and flexible straps, enabling a single attachment mechanism to serve multiple functions and reducing overall system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If containers have detachable and interchangeable handles and straps, then user adaptability is improved, but manufacturing complexity and assembly difficulty increase

Engineering Contradiction:

ImproveinterchangeabilityVSAvoidmanufacturing complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By segmenting the attachment system into modular components with standardized interfaces, the manufacturing process can be simplified. Each component (container body, handle, strap, buckle connector) can be manufactured independently using optimized processes, then assembled through straightforward attachment mechanisms.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The buckle connector design allows for parameter standardization in terms of connection geometry, attachment force requirements, and interface dimensions. This standardization enables manufacturing processes to be tuned for specific parameters, improving ease of production while maintaining interchangeability.

Inventive Principle:

Principle #35Parameter changes

AI summary

A container assembly includes a container body, one or more first buckle connectors, a strap, and a rigid handle. The container body includes a liner. The first buckle connectors are attached to the liner. The strap includes one or more second buckle connectors at the ends of the strap. The rigid handle includes one or more arms, a cross-bar, and one or more third buckle connectors. Each arm includes a cross-bar end and a buckle end. The cross-bar end is connected to an end of the cross-bar. The buckle end is connected to one of the third buckle connectors. Each second buckle connector and each third buckle connector are interchangeably coupled to each first buckle connector such that the strap and the rigid handle are interchangeable with and removably connectable to the one or more first buckle connectors.
