Carrier Latch Mechanism With Single-Actuator Auto Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carriers for work vehicles require manual attachment and latching of implements, lack efficient locking mechanisms, and are prone to wear, with high spare parts costs and limited integration with operator interfaces.
Innovation Solution
A carrier and latch mechanism featuring a pair of brackets, a latch mechanism with lock pins and actuator, and a shield plate, allowing for automated locking and unlocking, reduced wear, and integration with in-cab controls, while maintaining a secure locking force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual attachment and latching mechanisms are used, then device complexity is reduced, but productivity and ease of operation deteriorate due to manual labor requirements
Solution Approach 1:
The latch mechanism is designed to automatically engage and lock when the implement is inserted into the carrier. The lock pins are spring-loaded and automatically move into the latch receptacles upon insertion, eliminating manual latching operations while maintaining relatively simple structure.
Solution Approach 2:
The patent replaces manual mechanical latching operations with an automated mechanism that uses the insertion motion itself to trigger the locking action. The spring-loaded lock pins automatically engage with the latch receptacles without requiring separate manual locking steps.
2Reliability
If simple latch mechanisms are used, then device complexity is reduced, but reliability deteriorates due to wear and high spare parts costs
Solution Approach 1:
The latch mechanism is divided into separate functional components: lock pins, latch receptacles, and a shield plate. This segmentation allows each component to be optimized independently and facilitates easier maintenance and replacement of wear-prone parts without replacing the entire mechanism.
Solution Approach 2:
The shield plate is positioned to protect the latch mechanism from external damage and wear before failures occur. This protective element absorbs and distributes wear and damage, extending the service life of the locking components and reducing the frequency of replacements.
3Ease of operation
If automated locking mechanisms are integrated with in-cab controls, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The latch mechanism is designed with universal compatibility with standard in-cab control interfaces. The actuator can be controlled by various input methods (manual switch, sensor, or vehicle control system), allowing the same basic mechanism to serve multiple control scenarios without requiring complex specialized components.

AI summary
A carrier with a latch mechanism movable between a locked position and an unlocked position through operation of a single actuator. The actuator provides a locking force to maintain the latch mechanism in the locked position. A visible locking indicator is coupled to the latch mechanism to signal a locking status to an operator.
