Front Loader Hook Locking Mechanism for Work Vehicle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for connecting a front loader to the main body of a work vehicle are time-consuming, complex, and require manual handling of numerous components, leading to inefficiencies and convenience issues.
Innovation Solution
A front loader locking mechanism that includes a hook, spring, and pawl, allowing for the secure and efficient connection of the front loader to the main body by rotating the hook between two angular positions, simplifying the assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional manual connection methods are used for the front loader, then the connection can be achieved, but the assembly process is time-consuming and complex requiring multiple manual steps
Solution Approach 1:
The patent combines multiple connection functions into a single integrated locking mechanism. The hook structure integrates the latching action, locking engagement, and securing functions into one component that performs multiple operations simultaneously, eliminating the need for separate manual connection steps
Solution Approach 2:
The locking mechanism is designed to automatically lock and secure the front loader once the hook is engaged with the mounting structure. The spring-loaded pawl automatically engages with the notched element to lock the hook in place without requiring additional manual intervention or complex assembly procedures
2Ease of operation
If traditional connection methods are used, then the front loader can be attached, but it requires manual handling of numerous components making the process inconvenient
Solution Approach 1:
The patent extracts and eliminates unnecessary intermediate components from the connection process. By using a direct hook-to-mounting-structure interface with an integrated locking mechanism, the design removes the need for handles, separate latches, pins, or other manual manipulation components that would complicate the assembly process
Solution Approach 2:
The hook structure serves multiple functions simultaneously: it provides the primary connection interface, incorporates the locking mechanism through the pawl and notched element, and ensures secure attachment. This multi-functionality reduces the number of separate components needed and simplifies the overall connection process
