Cargo Vehicle Hanger with Rotatable Track Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hanger systems are inadequate for accommodating various types of tie down straps, leading to them being stored in different locations or left on the floor, where they can be damaged by hand carts or heavy cargo.
Innovation Solution
A hanger apparatus with a mounting plate, multiple hook apparatuses, ladder apparatuses with horizontal pins, and rotatable track connectors, designed to mount to a cargo vehicle's interior wall and couple with an E-track, allowing for the secure hanging of different types of tie down straps in a single location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional hanger systems are used, then tie down straps can be stored, but they cannot accommodate various types of tie down straps with different connectors
Solution Approach 1:
The hanger apparatus incorporates multiple types of hooks (J-hooks, S-hooks, G-hooks) and ladder apparatuses with horizontal pins on a single mounting plate, enabling one device to accommodate various connector types (ratchets, flat hooks, eyes) of different tie down straps. This multi-functional design resolves the contradiction by providing universal compatibility without requiring separate hanger systems for each strap type.
2Ease of operation
If tie down straps are stored in different locations or left on the floor, then they are easily accessible, but they are vulnerable to damage from hand carts or heavy cargo
Solution Approach 1:
The patent consolidates multiple storage locations into a single integrated hanger apparatus with mounting plate, hooks, and ladder structures. This unified structure provides centralized storage that is both accessible and protected, as all tie down straps are hung securely on the same apparatus rather than scattered in vulnerable locations.
3Adaptability or versatility
If a single hanger apparatus is used for all tie down straps, then organization is improved, but the system must accommodate diverse connector types
Solution Approach 1:
The hanger apparatus is divided into distinct functional segments: multiple hook types (J-hooks, S-hooks, G-hooks) for different connector shapes, and ladder apparatuses with horizontal pins for alternative attachment methods. This segmentation allows each component to specialize in accommodating specific connector types while collectively providing universal compatibility.
Solution Approach 2:
The patent utilizes vertical space by extending hooks upward from the mounting plate and positioning ladder apparatuses at different heights. This vertical arrangement accommodates multiple strap types in a compact footprint, reducing horizontal complexity while maintaining adaptability to various connector configurations.
4Adaptability or versatility
If track connectors are fixed in orientation, then the mounting structure is simpler, but they cannot adapt to different track orientations and vehicle configurations
Solution Approach 1:
The track connectors are designed to rotate relative to the mounting plate, transforming from a static fixed-orientation connection to a dynamic adjustable connection. This rotational capability allows the same hanger apparatus to adapt to different track orientations (horizontal, vertical, angled) and vehicle configurations without requiring multiple specialized mounting devices.

AI summary
A hanger apparatus includes a mounting plate configured to mount to a cargo vehicle, a plurality of hook apparatuses mounted to a first side of the mounting plate, wherein each hook apparatus extends out and up from the mounting plate, and at least one ladder apparatus mounted to the first side of the mounting plate. The ladder apparatus includes a plurality of horizontal pins extending between side rails, wherein the side rails are mounted to mounting plate and the horizontal pins are spaced apart from the mounting plate.
