Sliding Latch Hitch Hook for Secure Pin Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hitch configurations for work vehicles lack efficient and user-friendly mechanisms for hitching and unhitching, often requiring complex operations and prone to misalignment during towing operations.
Innovation Solution
A hitch hook system with a slideably supported latch and retainer mechanism that facilitates easy engagement and disengagement of the towing and towed vehicles, featuring a hook body with a pin-receiving opening and a handle for ergonomic operation, ensuring secure alignment and retention of the pin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional hitch configuration is used, then the structure is simple, but the hitching and unhitching operations are complex and time-consuming
Solution Approach 1:
The latch is designed to slide between two positions (first position allowing pin insertion, second position retaining the pin) rather than rotating or requiring complex mechanical movements. This sliding action simplifies the operation while providing secure engagement.
Solution Approach 2:
The retainer automatically engages with the latch in the second position to secure it without requiring additional manual intervention or complex locking mechanisms. The system self-secures once the latch is positioned correctly.
2Reliability
If a secure pin retention mechanism is implemented, then the connection reliability is improved, but the operation becomes more complex
Solution Approach 1:
The retention function is separated from the latch itself and implemented through a distinct retainer component that automatically engages with the latch. This extraction allows the latch to remain simple for operation while the retainer provides the security function.
Solution Approach 2:
The retainer acts as an intermediary between the latch and the pin, providing the security function without interfering with the simple sliding operation of the latch. It mediates between the user's simple action and the required secure retention.
3Productivity
If manual latch operation is used, then the device complexity is low, but the productivity during hitching operations is reduced
Solution Approach 1:
The sliding latch mechanism allows for rapid transition between engaged and disengaged states compared to traditional manual latch operations. The linear sliding motion is faster and more ergonomic than rotational or multi-step latching mechanisms.
Solution Approach 2:
The retainer automatically secures the latch in the engaged position without requiring additional manual steps. This self-securing feature eliminates the need for separate locking actions, improving operational speed while maintaining simplicity.

AI summary
A hitch hook includes a hook body with a hook opening configured to removably receive a pin of another work vehicle. The hitch hook further includes a latch that is slideably supported on the hook body between a first position and a second position relative to the hook body. The hook opening is open when the latch is in the first position, and the latch is configured to retain the pin within the hook opening when the latch is in the second position. The hitch hook additionally includes a retainer that is configured to retain the latch in the second position.
