Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carriers for work vehicles require manual attachment and latching of implements, lack efficient locking mechanisms, and have high replacement costs due to wear and complexity in actuator integration.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual attachment and latching mechanisms are used, then device complexity is reduced, but ease of operation and productivity deteriorate due to high manual effort and time consumption
Solution Approach 1:
The latch mechanism is designed to automatically engage and lock when the implement is attached to the carrier, without requiring manual intervention. The actuator automatically transitions the latch plates between locked and unlocked positions, allowing the system to serve itself during the attachment and detachment process
Solution Approach 2:
The patent replaces complex manual mechanical latching operations with an automated actuator system that uses hydraulic or pneumatic pressure to move the latch plates. This substitution eliminates the need for manual manipulation of multiple latching components while maintaining reliable locking
2Reliability
If complex latch mechanisms with multiple components are used, then reliability of locking is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The latch mechanism is divided into separate functional components: latch plates with lock pins on each side, an actuator for movement, and indicator systems. Each component has a specific function, and they work together to provide reliable locking. The segmentation allows for easier manufacturing and maintenance while ensuring reliability through distributed locking points
Solution Approach 2:
The patent combines multiple locking functions into a single integrated latch mechanism that operates through one actuator. The first and second latch plates with their respective lock pins are merged into a unified system controlled by a single actuator, reducing overall system complexity while maintaining reliable dual-side locking
3Productivity
If automated actuators are integrated into the carrier, then productivity and ease of operation improve, but device complexity and manufacturing precision requirements increase
Solution Approach 1:
The actuator is designed as a multi-functional component that performs both the locking and unlocking operations for both latch plates. It can be controlled through various interfaces (manual, hydraulic, pneumatic, or electronic), making it adaptable to different vehicle systems. This universality reduces the need for multiple specialized components and simplifies manufacturing requirements
Solution Approach 2:
The latch mechanism allows for adjustment of operational parameters such as the force required to actuate, the speed of engagement, and the position of the latch plates. These parameter changes can be achieved through simple modifications to the actuator control system or spring tensions, without requiring high-precision manufacturing tolerances on the mechanical components
Data Source
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.
