Solution Overview

Problem

Existing strap winding tools for flatbed trucks are complex to install and uninstall, requiring additional tools and taking significant effort to roll cargo straps for storage.

Innovation Solution

A strap winding apparatus with a bracket and rotating shaft assembly, featuring a frame, handle member, and hook member that easily attaches to a flatbed truck, allowing the shaft to wind straps and retract into the frame for storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If existing strap winding tools are used, then strap winding function is provided, but installation and uninstallation become complex requiring additional tools

Engineering Contradiction:

Improveease of installation and uninstallationVSAvoidconnection mechanism complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The device is divided into separate functional components: a bracket assembly that attaches to the truck and a rotating shaft assembly that winds the strap. The shaft can be independently removed from the bracket, allowing the winding function to be separated from the mounting structure. This segmentation enables simple hook-based attachment while maintaining effective strap winding capability.

Inventive Principle:

Principle #1Segmentation

2Productivity

If hand rolling of cargo straps is performed, then straps are organized for storage, but significant time and effort are required

Engineering Contradiction:

Improvestrap winding efficiencyVSAvoidtime required for manual rolling

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The rotating shaft assembly is designed to wind the strap automatically as it rotates. The strap feeds onto the shaft and winds itself through the rotation motion, eliminating the need for manual rolling operations. The user simply needs to rotate the shaft, and the strap winds itself efficiently onto the shaft for compact storage.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If existing strap winding tools with complex connection mechanisms are used, then strap winding is enabled, but additional tools are required for installation and uninstallation

Engineering Contradiction:

Improveease of attachment to flatbed truckVSAvoidnumber of additional tools required

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A simple hook member serves as an intermediary element between the bracket and the flatbed truck structure. The hook engages with existing features on the truck without requiring specialized installation tools. This intermediary connection method provides adaptability to various truck configurations while eliminating the need for additional installation tools.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A strap winding apparatus for winding a strap including a bracket and a rotating shaft assembly. The bracket includes a frame having frame holes. The bracket includes a handle member extending from the frame. The handle includes a hook member. The rotating shaft assembly includes a shaft having shaft openings. The shaft connects to a crank having a grip. The hook member connects to a flatbed truck and positions the frame parallel to the side of the flatbed truck. The shaft inserts through the frame holes while positioning the crank outside of the frame. The shaft openings receive the strap. The rotating shaft assembly rotates causing the strap to wind around the shaft. The shaft is removed from the frame while retaining the strap in a wounded configuration. In one example, the rotating shaft assembly is configured to position within the frame when not in use.
