Adjustable Cargo Net Structure for Mixed-Size Load Securing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cargo net devices struggle to securely fasten items of varying sizes and shapes in vehicles, requiring multiple cords and ropes, which can be cumbersome and error-prone, and lack visibility and strength for safe transport.
Innovation Solution
An adjustable cargo net device with a rectangular configuration and overhand knots allows sliding horizontal and vertical ropes to fit around objects, featuring brightly colored double-braided ropes and a fixed outer perimeter for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate cords and ropes are used to secure different sized items, then each item can be secured individually, but the device complexity and ease of operation deteriorate due to the need to manage multiple separate securing mechanisms
Solution Approach 1:
The patent implements a universal cargo net structure where a single net assembly with multiple adjustable knots can secure various sizes and shapes of cargo. The net replaces multiple separate cords and ropes with one integrated system that adapts to different cargo configurations through its adjustable knot design, thereby reducing device complexity while maintaining versatility
2Adaptability or versatility
If multiple separate cords and ropes are used to secure different sized items, then each item can be secured individually, but the ease of operation worsens due to the need to carefully secure each separate cord
Solution Approach 1:
The universal net design allows users to secure various cargo types with a single device, simplifying the operation by eliminating the need to select and manage multiple separate cords. The adjustable knots provide intuitive manipulation points that make the securing process easier while maintaining adaptability to different cargo sizes and shapes
3Ease of manufacture
If standard ropes are used, then the net is easy to manufacture, but the strength and visibility deteriorate for safe transport
Solution Approach 1:
The patent specifies using double-braided rope construction which combines multiple strands in a braided pattern, creating a composite structure that significantly enhances strength and durability compared to simple single-strand ropes. This composite approach maintains ease of manufacture through standardized rope production while dramatically improving the securing capability for safe transport
4Ease of manufacture
If standard ropes are used, then the net is easy to manufacture, but the visibility at night deteriorates
Solution Approach 1:
The patent incorporates brightly colored ropes (such as yellow, orange, or reflective materials) into the net construction to dramatically improve visibility during low-light and nighttime conditions. This color enhancement maintains ease of manufacture by using commercially available colored ropes while solving the critical safety issue of net visibility
5Adaptability or versatility
If adjustable knots are used to allow rope sliding, then the adaptability improves for fitting various cargo, but the device complexity increases
Solution Approach 1:
The patent divides the net into multiple segments connected by adjustable knots, allowing each section to be independently adjusted to fit different cargo dimensions. This segmentation provides high adaptability while keeping each individual knot simple and manageable, preventing the overall system from becoming overly complex

AI summary
An adjustable cargo net device is disclosed which comprises a net component that is configured in a rectangular base shape with attaching horizontal and vertical rows. The horizontal and vertical rows are adjustable by the overhand knot which connects them. Further, the overhand knot allows the rope to be slid to the right or left to adjust each square. Thus, the net component is relatively strong and adjustable. The device is also comprised of brightly colored ropes to allow for more visibility at night. Further, the net component comprises a fixed outer perimeter to easily secure the device to the vehicle. The end of each rope may also be torched to prevent fraying or other damage to the net component.
