Cargo Net Spanner for Easier Access to Secured Cargo Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cargo nets are difficult to access and manipulate, requiring users to hold the opening open with one hand while placing items with the other, limiting their utility and flexibility.
Innovation Solution
A deployable cargo net spanner that positions between two cords of the cargo net envelope, allowing users to access, place, or retrieve items more easily by engaging with cord attachment portions and rotating around one cord.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bungie pulls are used to secure the cargo net envelope, then the cargo net can be securely closed and tension can be maintained, but the opening becomes difficult to access and items cannot be easily placed or retrieved
Solution Approach 1:
A spanner tool is introduced as an intermediary device between the user's hand and the bungie pulls. The spanner has a handle for user grip and engagement features that interact with the bungie pulls, allowing users to open, close, and secure the cargo net envelope without directly manipulating the tight bungie pulls with their fingers.
Solution Approach 2:
The spanner is designed to be attached to the cargo net envelope itself, making it a self-contained tool that travels with the cargo net. The spanner can be stored on the cargo net when not in use, eliminating the need for separate storage or additional tools.
2Ease of operation
If a user holds the opening wide with one hand to access the cargo net, then items can be placed or retrieved, but the user cannot simultaneously secure the cargo net or perform other tasks
Solution Approach 1:
The spanner acts as a mechanical intermediary that replaces the user's hand for manipulating the bungie pulls. By attaching the spanner to the opening, the user can secure the cargo net with one hand while using the other hand to place or retrieve items, eliminating the need to hold the opening wide.
Solution Approach 2:
The spanner is positioned and attached to the cargo net opening in advance, preparing the system for easy access. Once attached, the spanner maintains the opening in a ready state, allowing users to quickly place or retrieve items without repeated manual adjustment.
3Reliability
If the cargo net envelope is kept closed to maintain security, then cargo is protected, but users cannot easily access or retrieve items
Solution Approach 1:
The spanner provides a mechanical advantage for quickly opening and closing the cargo net envelope. Users can rapidly manipulate the bungie pulls through the spanner mechanism, reducing the time needed to access cargo while maintaining security when closed.
Solution Approach 2:
The spanner enables dynamic control of the cargo net opening, allowing users to quickly transition between open and closed states. The spanner can be attached and detached easily, and the bungie pulls can be rapidly tensioned or relaxed to open or close the envelope as needed.

AI summary
Provided are a cargo net spanner and a cargo management system including the cargo net spanner. The spanner includes a tab protruding longitudinally from a proximal end of the spanner; a first cord attachment portion proximal to the tab; and a second cord attachment portion at a distal end of the spanner. The tab is configured to allow a user to control a movement of the spanner. The first cord attachment portion is configured to engage with a first cord. The second cord attachment portion is configured to engage with a second cord. The system includes a cargo net and the cargo net spanner(s). When the first cord and the second cord attachment portions are respectively engaged with the first and the second cords, the spanner positions between the first cord and second cord such that an internal space formed by the cargo net becomes more accessible by the user.
