Releasable Coupler for Reciprocating Slat Conveyor Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an easy-to-make and use releasable connection between conveying and lifting/holding slats on a dock and conveying and lifting/holding slats in a vehicle, which is not limited to conveyor slats but has general utility.
Innovation Solution
A connection system using a coupler member with a shim and lock surfaces that allows for push/pull action to connect and disconnect first and second portions of members, featuring an elongated coupler member that extends into a passageway and includes a hook mechanism for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a releasable connection system is implemented between conveyor slats on dock and vehicle, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The connection system is divided into separate components: a coupler member with lock surfaces, a distinct shim element, and passageways in both members. This segmentation allows each component to perform its specific function independently while simplifying the overall assembly and disassembly process.
Solution Approach 2:
The shim acts as an intermediary element between the coupler member and the second member. It facilitates the connection by being inserted into the passageway alongside the coupler member, enabling the lock surfaces to engage while maintaining ease of operation.
2Reliability
If lock surfaces are made to contact for secure connection, then reliability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The push/pull action between the first and second members automatically positions the lock surfaces into contact with each other. The members self-align through the mechanical interaction of the coupler member and shim, reducing the need for high manufacturing precision while ensuring reliable connection.
Solution Approach 2:
The connection system uses dynamic movement (push/pull action) to achieve proper alignment of the lock surfaces. Rather than relying on static precision, the system allows the members to move and self-position during the connection process, ensuring reliable engagement.
3Strength
If an elongated coupler member with hook mechanism is used, then strength of connection is improved, but ease of manufacture decreases
Solution Approach 1:
The coupler member is designed with distinct functional segments: the elongated body for insertion, the hook mechanism for engagement, and the lock surface for securing. This segmentation allows each feature to be manufactured using appropriate processes while maintaining overall strength.
Solution Approach 2:
The coupler member serves multiple functions: it provides structural strength through its elongated form, creates mechanical engagement via the hook, and enables locking through the lock surface. This multi-functionality is achieved through integrated design that doesn't significantly complicate manufacturing.

AI summary
A trailer (T) and a dock (D) are provided with substantially identical slat conveyors (10, 12). Each conveyor (10, 12) has alternating conveyor slats (36, 36′) and lifting/holding slats (38, 38′). The trailer (T) is backed up to the dock (D). Upper portions of the lifting/holding slats (38, 38′) are coupled together at their ends. The confronting ends of the conveying slats (36, 36′) are also coupled together. A mechanism carried by the dock (D) raises and lowers the upper portions of the two sets of lifting/holding slats (38, 38′) a drive mechanism carried by the dock (D) where it reciprocates both sets of conveying slats (36, 36′).
