Extendable Strap Cover System for Rapid Load Securing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for securing and covering loads in trucks and trailers are time-consuming and often inadequate, leading to objects falling or blowing off during transportation, which can cause safety hazards for other vehicles.
Innovation Solution
A cover system comprising a sheet and an extendable strap with couplers and fasteners that allows for quick and secure anchoring to structures, maintaining tension to hold the load in place, even when the strap is not actively being pulled.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional ropes or elastics are used to secure and cover loads, then the load can be secured and covered, but the process is time-consuming and often inadequate
Solution Approach 1:
The strap is divided into distinct functional segments: a first end portion with a coupler for anchoring, a middle portion for tensioning, a fastener section for securing to the sheet, and a second end portion with another coupler. This segmentation allows each part to perform its specific function efficiently, enabling quick attachment while ensuring reliable load securing through distributed tension points.
Solution Approach 2:
The single strap component performs multiple functions simultaneously: it secures the load to the truck bed, anchors the cover sheet to the structure, maintains tension on the load, and positions the cover properly. This multi-functionality eliminates the need for separate ropes, elastics, and anchoring devices, dramatically reducing the time required while maintaining adequate securing through integrated design.
2Reliability
If multiple ropes or elastics are used to adequately secure the load, then the load is more securely fastened, but the process becomes even more time-consuming
Solution Approach 1:
Multiple securing functions that traditionally required separate ropes and elastics are merged into a single integrated strap component. The strap combines anchoring capabilities at both ends, tensioning through its extendable middle portion, and load securing through the fastener section, all in one piece. This consolidation maintains adequate load security through distributed attachment points while reducing the time-consuming process of handling multiple separate components.
3Adaptability or versatility
If the strap is made extendable to accommodate load movement, then the load can be held in new positions, but maintaining tension becomes difficult
Solution Approach 1:
The strap incorporates an extendable middle portion that provides dynamic adjustment capability. When the load shifts to a new position, the extendable section allows the strap to lengthen and re-establish tension automatically. The fastener section then locks the strap at the new length, maintaining continuous tension on the load without requiring manual intervention. This dynamic design enables the strap to adapt to load movement while automatically maintaining securing force.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables rapid and effective securing and covering of loads, preventing objects from shifting or falling, thereby enhancing safety by maintaining load stability during transport.
Implementation Method 1
a strap having a length that is extendable... With tension in the strap and because the strap's length is extendable, the strap holds the load in place

AI summary
A cover for securing a load in an environment includes a sheet; a strap having a length that is extendable, and that includes a first end portion, a middle portion, and a second end portion; a first coupler attached to the strap's first end portion and operable to releasably attach the strap's first end portion to a structure other than the sheet to anchor the cover; a second coupler attached to the strap's second end portion and operable to releasably attach the strap's second end portion to a structure other than the sheet to anchor the cover; and a fastener operable to fasten the strap's first end portion to the sheet. When the sheet is used to secure and/or cover a load the first coupler is disposed between the fastener and the strap's middle portion. By having the first coupler located between the fastener and the strap's middle portion, one can both secure the load with the strap and secure the cover 10 to the structure. Thus, one can quickly, easily and adequately secure and cover a load with the cover.
