Solution Overview

Problem

In quick service restaurants (QSR) and food service settings, handling and preparing baked goods for sandwich assembly is inefficient due to the complexity of managing pre-sliced buns, which can lead to staleness and degradation, and increased menu options complicate the assembly process, making it difficult for workers to remember and execute orders accurately.

Innovation Solution

A bun separator system that includes a bun feeder, obstruction, and actuator to selectively separate pre-sliced buns into portions, directing them along specific feed paths for individual treatment, such as toasting, while maintaining a controlled environment to prevent degradation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If pre-sliced buns are held separately once sliced, then the interior of the baked good is exposed to air causing degradation, staleness, and mold, but keeping them together makes separation and individual treatment difficult

Engineering Contradiction:
Improvefreshness of baked goodsVSAvoidseparation and handling of bun portions
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The bun separator divides the bun into multiple portions (typically top and bottom halves) by introducing a separation element that splits the bun along its natural seam line, allowing each portion to be handled independently while maintaining freshness through controlled exposure

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary separation of bun portions at the point of use rather than pre-separating them earlier, which would expose them to air degradation. The bun remains intact during storage and transport, then is separated just before toasting or assembly

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If baked goods are toasted or treated individually, then sandwich assembly time increases (nearly half of total preparation time), but treating them together reduces efficiency and customization flexibility

Engineering Contradiction:
Improveindividual treatment of bun portionsVSAvoidsandwich assembly speed
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The system provides dynamic control over bun portion handling, allowing operators to direct different portions to different treatment paths (toasting, no toasting, different orientations) based on customer preferences and order requirements, optimizing both flexibility and efficiency

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The bun separator acts as an intermediary device between the bun storage and the toasting/assembly stations, directing portions to appropriate treatment paths and enabling parallel processing of multiple bun portions simultaneously

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If more menu options and customizations are offered, then customer satisfaction increases, but order assembly complexity increases and workers have harder time remembering instructions

Engineering Contradiction:
Improvemenu options and customizationsVSAvoidorder assembly complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system enables self-service operation where the bun separator and directing mechanism are designed to be intuitively operated with minimal training, allowing workers to handle complex orders through simple physical actions rather than complex memory-intensive procedures

Inventive Principle:
Principle #25Self-service

AI summary

A bun separator separates pre-sliced buns into portions. A bun feeder receives a pre-sliced bun having a plurality of portions and moves the pre-sliced bun along a first feed path. An obstruction is arranged relative to the first feed path and engages at least one portion of the plurality of portions of the pre-sliced bun. An actuator operates to selectively engage at least one portion of the plurality of portions of the pre-sliced bun against the obstruction to separate the least one portion of the pre-sliced bun and transfer the at least one portion to a second feed path.
