Solution Overview

Problem

Conventional food preparation equipment lacks ergonomic design, leading to difficulty in accessing ingredient containers, waste of spilled ingredients, and inefficient weighing processes, which increase operational costs and slow down food preparation.

Innovation Solution

A preparation table system with a movable grated work surface and integrated weigh scale that allows easy access to ingredient bins, recovers spilled ingredients, and enables ergonomic movement during food preparation, minimizing waste and improving efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of stationary object

If ingredient containers are located in openings below the work surface, then storage capacity is improved, but operator ergonomics deteriorate due to difficult reaching

Engineering Contradiction:
Improvestorage capacityVSAvoidoperator ergonomics
Core Design Contradiction:
Volume of stationary objectVSEase of operation

Solution Approach 1:

The ingredient containers are repositioned from below the work surface to the front edge of the work surface, changing the spatial dimension of access. This allows operators to reach ingredients directly in front of them rather than reaching down below, improving ergonomics while maintaining storage capacity through vertical stacking of multiple bins.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Loss of substance

If conventional bins are used to catch spilled ingredients, then ingredient recovery is improved, but operational efficiency deteriorates due to frequent manual redistribution

Engineering Contradiction:
Improveingredient recoveryVSAvoidoperational efficiency
Core Design Contradiction:
Loss of substanceVSProductivity

Solution Approach 1:

The bin system is designed to automatically redistribute spilled ingredients back onto the work surface through vibration or mechanical agitation, eliminating the need for manual intervention. The system self-regulates by detecting accumulated ingredients and automatically redistributing them, maintaining both high recovery rates and operational efficiency.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If separate weighing equipment is used, then measurement precision is improved, but process speed deteriorates due to lifting and returning products

Engineering Contradiction:
Improveportion accuracyVSAvoidpreparation speed
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The weighing function is integrated directly into the preparation surface, combining the work surface and weighing scale into a single unit. This eliminates the need to lift products off the surface for weighing, allowing continuous preparation flow while maintaining precise portion measurement through built-in sensors and display.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A preparation table is provided. The preparation table includes a cabinet with a work surface. The work surface includes a perimeter which defines a cavity of the cabinet. Opposing guide structures proximate opposing perimeter walls are configured to support a grate. The grate can be movable or stationary but is configured to support a product or product container while still providing access to the cavity. The product container is movable on the work surface to both rear and forward positions. The cabinet is configured such that excess ingredients fall from the product container, through the grate, and are recaptured within the cavity. The cabinet also includes a transition element which provides support for the product container as it is moved to an adjacent work surface.
