Automated Fruit Cutting Assembly for On-Demand Fresh Preparation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Quick service restaurants face challenges in providing fresh, consistent, and cost-effective cut fruit to customers due to limitations in handling and preparing whole fruits on demand, including safety concerns, inconsistency, and the need for preservatives in pre-packaged fruit slices.
Innovation Solution
A countertop apparatus that automatically washes, senses, and cuts whole fruits into consumable pieces using a lance and cutting assembly, directing waste to a disposal outlet without human handling, eliminating the need for preservatives and remote distribution centers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If pre-packaged fruit slices are prepared off-site and shipped to quick service restaurants, then fruit availability is improved, but storage space, refrigeration, and shipping costs increase
Solution Approach 1:
The fruit is washed and prepared for cutting in advance using the automated apparatus, but the actual cutting operation is delayed until the moment of customer order. This allows the fruit to be pre-treated for optimal cutting conditions while avoiding the need for long-term storage of pre-cut pieces, thereby reducing refrigeration and storage requirements while maintaining fruit availability
Solution Approach 2:
The automated cutting apparatus performs the cutting operation on-demand without requiring manual intervention or complex storage infrastructure. The system automatically processes whole fruits into cut pieces at the point of service, eliminating the need for off-site preparation facilities, refrigerated storage, and complex shipping arrangements
2Reliability
If preservatives are added to maintain fruit slices during storage, then fruit preservation is improved, but consumer appeal and healthiness decrease
Solution Approach 1:
The invention extracts and removes the need for preservatives by implementing on-demand cutting. Whole fruits are stored without any preservatives and are only cut when ordered, eliminating the requirement for chemical additives while maintaining fruit freshness and consumer appeal
Solution Approach 2:
The system accepts that cut fruit pieces have a limited shelf life and are consumed quickly after preparation. By cutting fruit on-demand and serving it immediately, the system eliminates the need for long-term preservation methods involving preservatives, accepting the short lifespan of fresh cut fruit as a trade-off for maintaining healthiness and consumer appeal
3Reliability
If whole fruits are hand-cut at the point of sale, then fruit freshness is improved, but service speed and consistency decrease
Solution Approach 1:
The automated cutting apparatus performs the cutting operation autonomously without requiring manual intervention. The system automatically impales the fruit on a lance, determines the cutting operation type, executes the cutting, and delivers cut pieces to a tray, all without human handling of the fruit, thereby maintaining freshness while dramatically increasing service speed
Solution Approach 2:
The invention replaces the manual mechanical cutting process with an automated mechanical system. The automated apparatus uses a lance and cutting assembly guided by sensors and controllers to perform cutting operations, substituting human labor with automated machinery that operates faster and more consistently while maintaining fruit freshness through minimal handling
4Productivity
If automated cutting apparatus is implemented, then service speed and consistency are improved, but initial cost and complexity increase
Solution Approach 1:
The automated cutting apparatus is designed to handle multiple types of fruits with a single machine. The system can process different fruit varieties and sizes by adjusting cutting parameters and selecting appropriate cutting operations, consolidating what would otherwise require multiple specialized devices into one universal machine, thereby reducing overall system complexity
Solution Approach 2:
The apparatus incorporates sensors that detect fruit characteristics such as size, shape, and type, and use this information to automatically adjust cutting parameters. This feedback mechanism allows the system to adapt to different fruits without requiring complex manual programming or multiple specialized devices, simplifying the overall system while maintaining high service speed and consistency

AI summary
An apparatus for preparing fruit includes a main housing with a cutting area containing a cutting assembly and a drive assembly, a removable cup assembly for inserting the fruit into the apparatus, and a removable drawer and tray for removing cut pieces of fruit from the apparatus after a cutting operation. The apparatus includes a rinsing assembly for cleaning the fruit and the cutting assembly, and a deflector configured to route cut pieces of fruit into the tray and waste material through a disposal outlet. The cutting assembly is configured to perform one or more cutting operations depending on the type of fruit detected in the cup assembly: wedging for apples, lemons, limes, and pears, and cutting/peeling for oranges and grapefruits. The apparatus quickly prepares various fruits for consumption without requiring an operator to touch the cut pieces of fruit.
