Strap Thrower Pole for Truck Load Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Securing large and tall loads on trucks with conventional straps is labor-intensive and hazardous due to the need for manual throwing or ladder use, requiring significant effort and risking injuries from heavy straps.
Innovation Solution
A strap thrower device featuring a pole with a strap throwing part that holds a rolled strap, allowing for efficient and controlled placement of straps over loads by propelling the strap while maintaining alignment, reducing manual effort and strain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual throwing of straps is used, then the straps can be placed over the load, but significant physical effort is required and injury risk increases
Solution Approach 1:
The patent introduces a strap thrower device as an intermediary tool between the worker and the strap. The device includes a throwing mechanism that launches the strap over the load, eliminating the need for manual throwing. The worker simply loads the strap into the device and activates the throwing mechanism, which propels the strap to the desired location, thereby reducing physical strain and injury risk while maintaining operational effectiveness.
Solution Approach 2:
The patent replaces the manual mechanical system (human arm throwing) with a mechanical throwing system. The strap thrower device uses a spring-loaded or elastic-based launching mechanism to propel the strap, substituting human physical effort with a mechanical system that can consistently throw straps with sufficient force and accuracy without causing worker injury.
2Length of moving object
If straps are thrown over tall loads, then the straps can reach the other side, but control and alignment become difficult
Solution Approach 1:
The strap thrower device serves as a controlled intermediary that manages the strap's trajectory. It includes guide channels or alignment features that ensure the strap is properly oriented before launch, and the throwing mechanism provides a consistent launch angle and force, enabling accurate placement even over tall loads without requiring manual adjustment during the throw.
Solution Approach 2:
The patent utilizes controlled parameter changes in the throwing mechanism to achieve both distance and precision. By adjusting the launch angle, force, and initial orientation of the strap within the device, the system can adapt to different load heights and distances while maintaining alignment precision. The mechanical design ensures these parameters are optimized for each throwing scenario.

AI summary
A strap holding and placement system that propels a rolled up strap over a load such as a truck bed. A handle attaches to a strap part that holds a rolled up strap. The strap part has multiple surfaces for holding the rolled strap. The multiple surfaces include a first rounded portion, which holds only a portion of the rolled strap, and a second curved portion above the rounded portion, which enables the strap to be propelled from the strap part from an area near a distal end of the strap part, when the handle is moved to propel the strap. The strap is held below the level of the front surface, in a rounded surface that is recessed below the front.
