Dual-Belt Conveyor Segmentation for Continuous Food Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional food and drink conveying systems face inefficiencies when the conveying path is long, as the next dish cannot be placed on the belt conveyor while it is in transit, leading to increased operational time and decreased efficiency in delivering ordered food and drink to customer seats.
Innovation Solution
The system incorporates a main belt conveyor and an auxiliary belt conveyor that extends from the kitchen, allowing the next dish to be placed on the auxiliary conveyor before the main conveyor stops, enabling continuous delivery of food and drink by controlling the conveyance operations and using sensors to manage dish placement and route changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single belt conveyor is used to convey dishes from the kitchen to customer seats, then the conveying path is established, but the next dish cannot be placed on the conveyor while it is in transit, resulting in increased operational time and decreased efficiency
Solution Approach 1:
The belt conveyor system is segmented into a first belt conveyor (for general dish conveyance) and a second belt conveyor (for pre-positioning dishes). This segmentation allows the second conveyor to prepare the next dish while the first conveyor is in transit, enabling continuous operation and eliminating idle time between dish deliveries.
Solution Approach 2:
The second belt conveyor performs preliminary action by pre-positioning the next dish to be conveyed before the current dish has completed its journey. This allows the system to prepare for the next delivery in advance, so that when the first conveyor becomes available, the next dish is already ready to be transferred, thus reducing operational time and increasing productivity.
2Area of stationary object
If the belt conveyor follows a long route to reach customer seats, then the conveying path covers more areas, but the period of operating time elongates, remarkably decreasing efficiency
Solution Approach 1:
The long conveying path is segmented into two functional zones: the first belt conveyor handles the long-distance transport from kitchen to customer seats, while the second belt conveyor handles the shorter pre-positioning segment. This segmentation allows the system to maintain extensive coverage while reducing the operational cycle time through parallel preparation activities.
Solution Approach 2:
The dual conveyor system ensures continuity of useful action by eliminating idle time. While the first conveyor is transporting a dish along the long route, the second conveyor continuously prepares the next dish, ensuring that the system is always in productive operation and maximizing the utilization of the conveying infrastructure.
3Ease of operation
If the belt conveyor stops to allow dish placement, then dishes can be loaded, but the conveying path operation is interrupted, reducing overall conveyance efficiency
Solution Approach 1:
The loading function is segmented from the conveying function. The second belt conveyor is dedicated to dish placement and preparation, while the first belt conveyor is dedicated to continuous conveyance. This segmentation allows dish placement to occur without interrupting the main conveying operation, as the second conveyor handles loading while the first remains in continuous motion.
Solution Approach 2:
The second belt conveyor acts as an intermediary between the kitchen (where dishes are prepared) and the first belt conveyor (which performs the main conveyance). This intermediary allows dishes to be transferred to the first conveyor in a controlled manner without requiring the first conveyor to stop, thus maintaining conveyance efficiency while enabling easy dish placement.

AI summary
The ordered food and drink conveying apparatus includes: a main belt conveyor to form a conveying path leading to a customer seat from a kitchen side of a restaurant; an auxiliary belt conveyor to be provided in extension from the main belt conveyor on the kitchen side to elongate the conveying path; and a control unit to operate the auxiliary belt conveyor and the main belt conveyor upon a conveyance start operation being performed and to convey the dish of the food and drink placed on the auxiliary belt conveyor to the customer seat, the control unit setting the auxiliary belt conveyor in a stop state enabling placement of the dish to be conveyed next on the auxiliary belt conveyor before stopping the main belt conveyor upon the dish being transferred onto the main belt conveyor from the auxiliary belt conveyor by performing the conveyance start operation.
