Securing Strap with Backup Interface for Ratchet Failure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ratcheting straps rely solely on their devices for high-tension securement, which can malfunction, leading to potential loss of items or cargo and risk of injury or death, with no integrated backup securement mechanism.
Innovation Solution
A securing strap with at least two strap securing interfaces, including a strap securing rod and D-ring, that can maintain object securement even if the ratcheting device fails, providing additional protection and ease of use across various applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a ratcheting strap relies solely on the ratcheting device for high-tension securement, then the securement strength is improved, but the reliability deteriorates due to potential malfunction or failure of the ratcheting device
Solution Approach 1:
The patent incorporates a backup securement mechanism (such as a secondary ratcheting device, cam buckle, or locking mechanism) integrated into the strap system that activates automatically or can be manually engaged if the primary ratcheting device fails. This beforehand cushioning ensures that the securement function is maintained even when the primary mechanism malfunctions, thereby improving reliability without compromising securement strength
Solution Approach 2:
The patent applies different securement mechanisms at different locations along the strap. The primary ratcheting device provides high-tension securement at one location, while a backup securement mechanism is positioned at another location to provide redundant protection. This local differentiation allows the system to maintain both strength and reliability through distributed securement capabilities
2Reliability
If a backup securement mechanism is added to the strap, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The patent integrates the backup securement mechanism into the existing strap structure by combining it with the webbing, stitching, or housing of the primary ratcheting device. This merging approach allows the backup mechanism to share structural elements with the primary system, thereby improving reliability while minimizing the increase in overall device complexity
Solution Approach 2:
The backup securement mechanism is designed to serve multiple functions: it acts as a redundant security feature, provides an additional tightening capability, and can function as a manual release mechanism. This multi-functionality reduces the need for separate dedicated components, thereby improving reliability without proportionally increasing device complexity

AI summary
A securing strap having at least two strap securing interfaces that functions in combination with a ratcheting device. The strap has a first end, a second end, an inner surface, an outer surface, an upper edge, and a lower edge. The first end of the strap is looped around a strap attachment rod on the ratcheting device and extends back over a section of the strap allowing the two strap sections to be attached. At intervals along the two attached strap sections, attachment means are used to create openings, into which the at least two strap securing intervals and at least one strap securing member are inserted when securing an object. Once the strap is inserted through the ratcheting device, the two securing interfaces and the at least one securing member, the strap remains in place securing the object even if the ratcheting device fails.
