Solution Overview

Problem

Existing avocado preparation devices are bulky, inefficient in accommodating pits of different sizes and shapes, and struggle with cleaning avocado residue from their blades.

Innovation Solution

A compact avocado pitting device with a housing and engagement members that securely retain the pit, allowing easy removal without damaging the fruit, and a handle with integrated blade members for cutting and slicing, designed to accommodate varying pit sizes and shapes, and facilitate cleaning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a lasso-like blade is used to carve the pit from the fruit, then the pit can be removed, but the device becomes bulky and cannot accommodate pits of different sizes and shapes

Engineering Contradiction:

Improveaccommodation of different pit sizes and shapesVSAvoidbulkiness of the device

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device uses a recess with engagement members that can adapt to different pit sizes and shapes by adjusting the engagement depth and position, rather than requiring different tools for different pit variations

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The single device structure with a recess and engagement members serves multiple functions: holding the pit securely, accommodating various pit sizes and shapes, and enabling easy removal without requiring multiple specialized tools

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Productivity

If spaced apart blades are used for slicing the fruit, then the fruit can be sliced while removing it from the skin, but avocado residue becomes trapped in the spaces between blades making cleaning difficult

Engineering Contradiction:

Improveslicing efficiencyVSAvoidcleaning difficulty

Core Design Contradiction:

ProductivityVSEase of manufacture

Solution Approach 1:

The patent extracts the slicing function from the multi-blade structure and separates it from the pit removal function, eliminating the trapped residue problem by removing the spaced apart blade configuration

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The design accepts that the blade may need periodic replacement or cleaning, prioritizing ease of maintenance over permanent residue-free operation, allowing for simple cleaning protocols

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Device complexity

If a sharp knife is used to perform all tasks, then the tool is simple, but the process is time-consuming and may damage the fruit

Engineering Contradiction:

Improvetool simplicityVSAvoidpreparation speed

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The patent combines multiple functions (pit removal and slicing) into a single integrated device, maintaining tool simplicity while significantly improving preparation speed and reducing fruit damage compared to sequential knife operations

Inventive Principle:

Principle #5Merging (Combining)

AI summary

An avocado pitting device comprises a housing having an inner surface defining a recess. The recess is configured to receive a pit of an avocado. An engagement member projects inwardly from the housing inner surface. The engagement member is configured to engage the pit and retain the pit within the recess such that the pit is removable with the housing from the avocado.
