Solution Overview

Problem

Existing carrying handles suffer from limitations such as inadequate rigidity, poor tolerance, and difficulty in quick movement of structures without lag.

Innovation Solution

A handle assembly comprising a handle with a passageway and a fastener with connectors and an elongate body, configured to surround structure portions, extend through the handle, and form a continuous loop to securely position the handle between structure portions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If a handle assembly is designed to quickly affect movement of a structure, then the response speed improves, but the rigidity and tolerance control become more difficult to maintain

Engineering Contradiction:

Improveresponse speedVSAvoidrigidity and tolerance control

Core Design Contradiction:

SpeedVSManufacturing precision

Solution Approach 1:

The handle assembly incorporates a passageway extending through the handle body that allows dynamic adjustment and secure positioning of the fastener, enabling the assembly to adapt to different structural configurations while maintaining rigidity. The fastener system can be quickly installed and removed, providing rapid deployment while ensuring tight tolerances when engaged.

Inventive Principle:

Principle #15Dynamics

2Strength

If the handle assembly is made rigid to maintain shape and structure, then the strength improves, but the ease of installation and adjustment decreases

Engineering Contradiction:

Improvehandle strengthVSAvoidinstallation ease

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The handle assembly is divided into distinct components: a handle body with an internal passageway, a fastener with connectors, and mounting portions. This segmentation allows each component to be manufactured independently with optimal rigidity, while the assembly process remains simple and tool-free, requiring only insertion and connection of the fastener through the passageway.

Inventive Principle:

Principle #1Segmentation

3Ease of manufacture

If the handle assembly uses a simple design for ease of manufacture, then the manufacturing complexity reduces, but the reliability of secure positioning decreases

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidsecure positioning reliability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The fastener is designed to extend through the passageway of the handle body, with the elongate body of the fastener passing through the hollow interior of the handle. This nested configuration ensures that the fastener is securely positioned within the handle structure, preventing lateral movement while maintaining a simple two-piece design that is easy to manufacture and assemble.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

A handle assembly comprises a handle and a fastener. The handle includes a first end, a second end opposite the first end, and a passageway. The fastener includes a first connector, a second connector, and an elongate body. The elongate body of the fastener is configured to at least partially surround a first portion of a structure disposed, extend through the passageway of the handle, and at least partially surround a second portion of the structure. The fastener is configured to form a continuous loop by connecting the first connector to the second connector to fixedly positon the handle between the first portion of the structure and the second portion of the structure.
