Insulated Container With Telescoping Handle For Heavy-Load Transport

Solution Overview

Problem

Existing containers, especially when fully loaded, are difficult to transport by a single person and often require multiple handling options that are not convenient for storage in small spaces.

Innovation Solution

A container design featuring a telescoping handle and bail handle, combined with roller wheels, allowing for both carrying and rolling transport, with integrated features for secure closure and easy access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the container is designed with a fixed handle for carrying, then it is simple in structure, but it becomes difficult to transport when fully loaded and heavy

Engineering Contradiction:

Improveease of transportVSAvoidcontainer weight

Core Design Contradiction:

Ease of operationVSWeight of moving object

Solution Approach 1:

The patent applies the dynamics principle by making the handle telescopic rather than fixed. The handle can extend to provide leverage when the container is heavy and full, then retract to a compact position when not in use or when the container is light. This dynamic adjustment allows the same handle to accommodate varying weight conditions, solving the contradiction between ease of transport and container weight.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If the container provides multiple transport options (carrying and rolling), then it increases versatility, but it increases device complexity

Engineering Contradiction:

Improvetransport optionsVSAvoidhandle assembly complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the universality principle by designing a multi-functional handle assembly that combines both carrying and rolling capabilities in a single integrated structure. The telescopic handle can function as a carrying handle when extended, and the same assembly incorporates roller wheels that can be deployed for rolling transport. This multi-functional design increases versatility while managing complexity through integration rather than separate components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent applies the nested doll principle by incorporating the roller wheels within the telescopic handle assembly. The wheels are nested inside the handle structure when not in use, and can be deployed when needed for rolling transport. This nesting approach allows multiple transport functions to coexist in a compact form, increasing versatility while minimizing the increase in device complexity.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Volume of moving object

If the container allows compact storage in small areas, then it saves space, but it limits access to transport features

Engineering Contradiction:

Improvestorage spaceVSAvoidaccess to handles

Core Design Contradiction:

Volume of moving objectVSEase of operation

Solution Approach 1:

The patent applies the dynamics principle by making the handle telescopic rather than fixed. The handle can extend to provide leverage when the container is heavy and full, then retract to a compact position when not in use or when the container is light. This dynamic adjustment allows the same handle to accommodate varying weight conditions, solving the contradiction between ease of transport and container weight.

Inventive Principle:
