Vending Shelf Conveyor Coupling With Exposed Gear Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing dispensing mechanisms in article vending machines face difficulties in coupling the drive section to the dispensing unit due to the hidden coupled portion, making it challenging to align and connect the output shaft of the drive section with the input shaft of the dispensing unit.
Innovation Solution
A dispensing mechanism with a gear system where a part of the gear is exposed through a cover, allowing easy rotation and alignment of the input shaft, facilitating the coupling of the output shaft from the drive section to the input shaft of the dispensing unit, which includes a movement mechanism and a cover with an opening to expose the gear for manual rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the coupled portion is located in an inner part of the shelf, then the structure is compact, but it becomes difficult to visually see and couple the dispensing unit to the drive section with ease
Solution Approach 1:
A guide member is introduced as an intermediary component between the drive section and dispensing unit. The guide member includes a guide groove that receives and guides the input shaft during coupling, and a guide protrusion that aligns with the groove to facilitate precise connection. This intermediary structure makes the hidden coupling process visible and controllable, resolving the contradiction between compact structure and easy operation.
2Reliability
If rotation alignment is required during coupling, then power transmission is achieved, but the coupling process becomes difficult due to the hidden coupled portion
Solution Approach 1:
The guide member serves as a mediator that provides visual and physical guidance for the rotation alignment process. The guide groove and guide protrusion work together to indicate when proper alignment is achieved, making the previously hidden and difficult rotation alignment process observable and manageable.
Solution Approach 2:
The guide groove and guide protrusion are designed to automatically align and engage during the coupling process. As the input shaft is inserted, the guide structures self-adjust to provide the correct rotational alignment, eliminating the need for complex external alignment tools or procedures.
