Solution Overview

Problem

Current fruit and vegetable blending machines require user intervention for the entire blending and cleaning process, including selecting ingredients, loading, blending, and cleaning, which is inefficient and not fully automated.

Innovation Solution

An automatic blender system with an annular internal cleaning element that uses water projection holes to automatically clean the blending area and ducts, connected to a water supply system, allowing for automated waste removal and preparation of a smoothie without user intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If the blender machine is designed to be fully automatic including cleaning, then the extent of automation is improved, but the device complexity increases due to additional cleaning components

Engineering Contradiction:
Improveautomation of cleaning processVSAvoidcomplexity of cleaning system
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The pusher tube is designed to perform multiple functions: it acts as both a pushing mechanism during blending and as a cleaning element during the cleaning phase. The same component that pushes food during operation is used to spray water and remove waste, eliminating the need for separate cleaning mechanisms and reducing overall device complexity while maintaining full automation.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system performs self-cleaning by using its own components (pusher tube, water reservoir, pump) to clean itself automatically after blending. The pusher tube sprays water through its own structure to flush waste from the ducts, and the system manages the entire cleaning process without external intervention, achieving self-service functionality.

Inventive Principle:
Principle #25Self-service

2Device complexity

If manual cleaning is required after blending, then the device complexity is reduced, but the loss of time increases due to user intervention for cleaning

Engineering Contradiction:
Improvesimplicity of system structureVSAvoidtime for cleaning operation
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The system performs preliminary cleaning action by flushing water through the ducts and blending area immediately after the blending cycle completes. The pusher tube sprays water to prevent waste from drying and adhering to surfaces, and the pump actively removes waste before the user needs to intervene, saving time while maintaining relatively simple device structure.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses hydraulic principles by employing a pump to circulate water through the cleaning system. Water is pressurized and sprayed through the pusher tube to effectively remove waste from ducts and the blending area, enabling automated cleaning without requiring complex mechanical scraping or brushing mechanisms.

Inventive Principle:
Principle #29Pneumatics and hydraulics

3Device complexity

If the pusher tube remains in the feeding duct, then the device complexity is reduced, but the object-generated harmful factors increase due to waste accumulation in the ducts

Engineering Contradiction:
Improvesimplicity of component placementVSAvoidwaste accumulation in ducts
Core Design Contradiction:
Device complexityVSObject-generated harmful factors

Solution Approach 1:

The system switches between blending mode and cleaning mode periodically. During the cleaning phase, the pusher tube performs a cleaning action by spraying water through its structure, flushing waste from the feeding duct. This periodic cleaning action prevents waste accumulation while keeping the pusher tube in place, maintaining simplicity without generating harmful factors.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The pusher tube, which would normally just push food during blending, is designed to also function as a cleaning spray nozzle. The same structure that contacts food during operation becomes the delivery mechanism for cleaning water, converting a potential source of contamination into a beneficial cleaning tool that prevents waste accumulation.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

Automatic cleaning system for a blender that includes a feeding duct, configured to locate the food inside it; food blending media; a pusher element, configured to bring the food closer and obtain the blend; and a dispensing conduit configured to lead the liquid obtained to a container that comprises a cleaning system with internal cleaning elements with: at least one water projection hole; means for conducting water from an internal and/or external supply; and means for propelling water from the feed to the orifices for projecting water through the conduction means; where the cleaning elements are configured to act automatically and/or manually after a food blending procedure, spray water through the water projection holes, and drag the remains of the blended food out of the blender.
