Restaurant Elevator Transport System for Gravity-Based Food Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing restaurant systems face challenges in transporting food and drinks from a working area to a guest area without the need for manual intervention, especially when the working area is not elevated relative to the guest area, as they rely on gravity-based transport which requires a minimum potential energy difference.
Innovation Solution
Incorporating a second transport section with an elevator that positions food and drinks at a higher point than the guest area, converting potential energy into kinetic energy to facilitate gravity-based transport through a first transport section, allowing food and drinks to move without additional drives and overcome frictional forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If gravity-based transport is used from working area to guest area, then energy consumption is reduced, but the working area must be located at a higher point than the guest area
Solution Approach 1:
The transport system is divided into multiple sections: a first transport section for gravity-based transport and a second transport section with an elevator for vertical transport. This segmentation allows the working area and guest area to be arranged at different heights while maintaining energy-efficient gravity transport in the horizontal section.
Solution Approach 2:
An intermediate elevator system is introduced to bridge the height difference between the working area and guest area. The elevator acts as a mediator that vertically transports food and drinks between floors, enabling gravity-based transport in the horizontal direction without requiring the working area to be elevated.
2Device complexity
If the working area is elevated above the guest area for gravity transport, then food and drinks can be transported without additional drives, but the layout becomes constrained
Solution Approach 1:
The transport system is segmented into a vertical section (elevator) and a horizontal section (gravity transport). This allows the horizontal transport section to remain simple and drive-free while the vertical section handles height differences, providing layout flexibility without compromising transport simplicity.
Solution Approach 2:
The solution moves the height adjustment from the horizontal transport plane to the vertical dimension by introducing an elevator. This dimensional separation allows the horizontal transport to maintain its simple gravity-based operation while the vertical dimension handles the elevation requirements through the elevator system.
3Adaptability or versatility
If manual service is used to deliver food and drinks, then height and location constraints are eliminated, but labor requirements increase
Solution Approach 1:
The transport system is designed to be self-service, automatically transporting food and drinks from the working area to the guest area using gravity and elevator mechanisms. This eliminates the need for manual carrying by staff while maintaining location flexibility, thereby improving labor efficiency without sacrificing adaptability.
4Reliability
If electric conveyor belts are used for transport, then transport reliability is improved, but energy consumption increases
Solution Approach 1:
The transport system is divided into sections with different drive mechanisms: electric drives are used only where necessary (vertical transport via elevator), while gravity-based transport is used in horizontal sections. This segmentation maintains reliability through controlled electric intervention while minimizing overall energy consumption.
Solution Approach 2:
The electric drive function is extracted from the entire transport system and applied only to the specific section where it is necessary (the elevator for vertical transport). The remaining horizontal transport sections use passive gravity-based mechanisms, reducing overall energy consumption while maintaining transport reliability through targeted active control.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables impact-free delivery of food and drinks to the guest area, allowing for arbitrary arrangement of working and guest areas, reducing energy consumption, and overcoming height limitations by converting potential energy into kinetic energy for efficient transport.
Implementation Method 1
the second transport section has an elevator (7), which is designed to transport the food and/or drinks into a position, which is located at a higher point as compared to the guest area (3)
Implementation Method 2
the transport of food and/or drinks from the working area (2) to the guest area (3) takes place at least in sections by means of the force of gravity
Implementation Method 3
the transport of the food and/or drinks by means of the force of gravity as known from DE 10 2005 059 188 B4 and EP 1 833 331 B1, requires a minimum level of potential energy of the food and/or drinks
Implementation Method 4
The food and/or drinks also continue to move without an additional drive in the first transport section at least in sections in this manner. By converting the potential energy, which is supplied in the second transport section, into kinetic energy, the food and/or drinks can also overcome frictional forces
