Dynamic-Tension Cargo Strap for Vibration-Absorbing Securement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cargo straps are excessively rigid, leading to damage of cargo due to inability to absorb vibrations or shifts during transport and lack of controlled tension release.
Innovation Solution
A ratcheting cargo strap apparatus with a spring component that provides dynamic tension, allowing the strap to adjust to cargo movements, absorbing energy from vibrations and maintaining securement without losing tension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional rigid cargo straps are used, then cargo is securely held in place, but cargo may be damaged due to inability to absorb vibrations or shifts during transport
Solution Approach 1:
The cargo strap system incorporates a spring component that transforms the static, rigid strap into a dynamic system. The spring allows the strap to flex and absorb vibrations and shifts during transport, preventing cargo damage while maintaining securement. The spring's elastic deformation enables the system to adapt to moving conditions rather than resisting them rigidly.
Solution Approach 2:
The spring component changes the mechanical parameters of the strap system by introducing elasticity. This allows the strap to change its tension and length dynamically in response to vibrations and cargo movements, converting the fixed-parameter rigid strap into a variable-parameter flexible system that can absorb harmful vibrations.
2Object-affected harmful factors
If bungee-type cargo straps are used to provide flexibility, then vibrations can be absorbed, but tension cannot be controlled and safe release means are lacking
Solution Approach 1:
The cargo strap system is segmented into distinct functional components: the flexible strap portion for vibration absorption, the spring component for maintaining tension, and the ratchet assembly for controlled tensioning and safe release. This segmentation allows each component to perform its specific function optimally while working together as an integrated system.
Solution Approach 2:
The ratchet assembly acts as an intermediary mechanism between the flexible strap and the user. It provides controlled tension by allowing the strap to be tightened in discrete increments and maintains that tension automatically. For release, the ratchet provides a safe, controlled mechanism to gradually reduce tension rather than sudden release, giving the user precise control over the entire tensioning and releasing process.
3Adaptability or versatility
If natural or synthetic rubber is used to provide tension, then flexibility is achieved, but the same weaknesses as bungee straps persist
Solution Approach 1:
The invention merges three distinct components into a unified system: the flexible strap (providing adaptability), the spring (providing controlled tension through elastic force), and the ratchet assembly (providing controlled operation for tightening and release). This combination retains the flexibility and vibration absorption of rubber-like materials while adding the tension control and safe release capabilities of mechanical systems.

AI summary
A ratcheting strap apparatus is provided which effectuates dynamic tension when securing a load to allow for shifting, sinking, or certain movements of the items being secured to prevent damage of such items. The ratcheting cargo strap may include a strap, a ratchet assembly, a spring, a compression component, and a hook wherein the strap may be configured as a single continuous strap without interconnecting links and wherein the strap may be attached to the ratchet assembly on one end and includes free slack on the opposite end of the strap. The strap may be configured to extend through the spring as well as through a loop of the hook on one end of the spring and around a compression component on the opposite end of the spring.
