Rotatable Cargo Bed Anchor with Claw End
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing cargo on cargo carrying vehicles are often unreliable, prone to disengagement due to vibration during transport, and can cause permanent deformation or damage to vehicle structures.
Innovation Solution
The development of releasible cargo bed engaging anchors with a rotatable base and cap, featuring a claw end with a hook and gap configuration, and a swivel joint option, which can engage multiple types of ties and distribute force to prevent deformation, allowing for secure and adjustable attachment to cargo beds without causing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional ties are used to secure cargo, then cargo can be held in place, but the ties are prone to disengagement due to vibration during transport
Solution Approach 1:
The anchor incorporates a rotatable base that can dynamically adjust its orientation during transport. This rotational capability allows the anchor to adapt to vibrations and movements, maintaining secure engagement with the cargo bed while accommodating dynamic forces that would otherwise cause disengagement of fixed anchors.
Solution Approach 2:
The anchor is divided into distinct functional segments: a base portion that interfaces with the cargo bed, a rotatable connection mechanism, and a tie-engaging portion. This segmentation allows each component to perform its specific function independently, with the rotatable connection absorbing vibrational stresses while the other segments maintain their securing functions.
2Strength
If traditional securing methods are used, then cargo can be attached, but permanent deformation or damage to vehicle structures can occur
Solution Approach 1:
The anchor acts as an intermediary device between the tie and the cargo bed. Instead of the tie directly contacting and potentially damaging the cargo bed, the anchor provides a dedicated engagement point with a claw end designed to grip the tie securely. This intermediary structure distributes forces appropriately and prevents direct damage to the vehicle's cargo bed structure.
Solution Approach 2:
The anchor's claw end features a specific geometric configuration with a gap and hooked portion that changes the interaction parameters between the tie and the anchor. The gap allows the claw to engage the tie in a controlled manner, distributing the securing force across multiple contact points rather than concentrating it, thereby preventing deformation of either the tie or the cargo bed.
3Reliability
If fixed anchors are used, then cargo can be secured, but the anchors cannot accommodate different tie orientations or types
Solution Approach 1:
The rotatable base enables the anchor to dynamically change its orientation to accommodate different tie directions and types. Whether the tie approaches horizontally, vertically, or at an angle, the base can rotate to present the appropriate engagement surface, making the anchor versatile for various cargo securing configurations while maintaining reliable engagement.
Solution Approach 2:
The anchor is designed as a universal securing device that can engage multiple types of ties (ropes, chains, straps) in multiple orientations. The combination of the rotatable base and the specifically designed claw end creates a multi-functional anchor that replaces the need for multiple specialized anchors, enhancing adaptability while maintaining securing reliability across different applications.

AI summary
A cargo carrying vehicle (10, 130) includes a load supporting deck (24, 132). Cargo supported on the deck may be secured through releasible engaging anchors (32, 110). The anchor includes a base (34, 112) and a cap (36, 114). The base and cap are relatively rotatable about a pivot (64, 116). The base includes a claw end (40) configured for engaging a ledge projection (58) of a cargo bed (60). The cap includes a post (68, 122) and a cleat (70, 128) which bound a tie engaging recess (104). The cleat (70) also includes an aperture (90) suitable for accepting further ties therein.
