Wireless Cargo Restraint Tension Monitoring and Auto-Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cargo restraint systems are inadequate in monitoring tension levels, leading to potential cargo shifts, driver injuries, and increased time and effort in securing loads, as they lack real-time feedback and automatic adjustment capabilities.
Innovation Solution
A smart cargo restraint system equipped with load sensors and a controller that monitors tension, filters noise, and automatically adjusts the securing member's tension, alerting drivers to necessary adjustments and reducing manual effort and time spent on securing cargo.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If passive tie down systems are used to secure cargo, then the cargo restraint function is provided, but the system cannot alert drivers when the load has shifted or the restraint has come loose
Solution Approach 1:
The patent implements feedback by installing load sensors on the securing members that continuously monitor tension levels and transmit this information to a controller, which then alerts the driver when tension drops below threshold levels indicating cargo shift or restraint failure
Solution Approach 2:
The patent replaces the purely mechanical passive tie-down system with an integrated electromechanical system that incorporates electronic sensors, controllers, and alert mechanisms to provide real-time monitoring and information feedback about cargo restraint status
2Reliability
If drivers constantly stop their vehicle to inspect cargo restraints, then cargo security is verified, but the stops are dangerous and time consuming
Solution Approach 1:
The system provides continuous real-time feedback through driver alerts that immediately notify when cargo restraint status changes, eliminating the need for periodic manual inspections and allowing drivers to maintain awareness without stopping the vehicle
Solution Approach 2:
The monitoring system operates autonomously without requiring driver intervention, automatically detecting cargo shifts or restraint failures and notifying the driver, thereby freeing the driver from time-consuming manual inspection tasks
3Ease of manufacture
If workers manually secure heavy cargo using chains and binders, then the cargo is restrained, but the effort results in strains and injury
Solution Approach 1:
The patent replaces manual mechanical operations with automated electromechanical systems that automatically tension and monitor securing members, eliminating the need for workers to physically handle heavy chains and binders
Solution Approach 2:
The system performs self-tensioning and self-monitoring operations automatically, with the cargo restraint system managing its own securing function without requiring manual physical effort from workers
4Ease of manufacture
If securement devices are heavy and require crawling around the vehicle, then the cargo can be restrained, but the operation becomes more difficult as one ages
Solution Approach 1:
The patent replaces heavy manual mechanical devices with lightweight automated systems that can be operated through electronic interfaces, significantly reducing the physical strength and mobility requirements for operation
Solution Approach 2:
The system performs securing operations automatically without requiring manual manipulation of heavy components, allowing operation by individuals regardless of age or physical capability through simple electronic controls
5Ease of manufacture
If securing cargo is done manually with heavy devices, then the cargo is restrained, but the activity is time consuming
Solution Approach 1:
The patent replaces time-consuming manual operations with automated electromechanical systems that can rapidly tension and secure cargo, dramatically increasing the speed of the securing process
Solution Approach 2:
The system can pre-tension securing members and prepare the cargo restraint system before cargo loading is complete, and automatically adjust tension during transport, reducing the overall time required for securement operations

AI summary
A cargo restraint system includes a body, a first connecting end and a second connecting end on opposing sides of the body, wherein the first and second connecting ends are coupled to a securing member which is used to restrain the cargo. One or more load sensors are coupled to the first connecting end and/or the second connecting end. A controller is coupled to the one or more load sensors. The controller is configured to receive tension information from the one or more load sensors. The controller includes a transmitter capable of transmitting the tension information to a remote device. The controller may include a database to store the information.
