Solution Overview

Problem

Food processors often fail to achieve an optimal blending level, leading to unsmooth mouthfeel due to undigested dietary fibers and nutrient loss from over-blending, as they lack effective monitoring to determine the desired fine and homogeneous particle size and nutrient retention.

Innovation Solution

A monitoring apparatus with sensors, such as particle image analysis, conductance, and refractive index measurement systems, integrated into or connected with food processors to continuously monitor particle size, electrical conductivity, and soluble solids content, providing real-time feedback to control the blending process and terminate it when predetermined nutrient values are met.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If food is blended for longer time or with higher intensity to achieve finer particle size, then the homogeneity and nutrient release are improved, but heat is generated that reduces micronutrients in the food

Engineering Contradiction:
Improveparticle size uniformityVSAvoidmicronutrient loss
Core Design Contradiction:
Manufacturing precisionVSLoss of substance

Solution Approach 1:

The patent employs sensors (optical, electrical conductivity, temperature) that continuously monitor food characteristics during blending and provide real-time feedback to the control system. This feedback mechanism allows the system to adjust blending parameters dynamically, achieving fine particle size uniformity without excessive heat generation that would cause micronutrient loss.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The blending process is made dynamic through continuous adjustment of blade speed and operation cycles based on real-time sensor data. The system transitions from static fixed-time blending to dynamic adaptive blending, modifying operational parameters to maintain optimal conditions for particle size reduction while preventing heat-induced nutrient degradation.

Inventive Principle:
Principle #15Dynamics

2Quantity of substance

If food is blended to reduce particle size for better nutrient intake, then the bioavailability is improved, but over-blending generates heat that reduces micronutrients

Engineering Contradiction:
Improvenutrient bioavailabilityVSAvoidmicronutrient reduction
Core Design Contradiction:
Quantity of substanceVSLoss of substance

Solution Approach 1:

Sensors monitor electrical conductivity and optical properties that correlate with nutrient release and particle size. The control system uses this feedback to determine when optimal nutrient bioavailability is achieved, stopping the process before over-blending occurs and causing heat-related micronutrient loss.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces purely mechanical blending judgment with sensor-based detection systems (optical sensors, electrical conductivity sensors) that objectively measure nutrient release and particle size, eliminating the need for extended blending times that would generate harmful heat.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If traditional food processors operate without monitoring to ensure thorough blending, then the operation is simple, but they fail to achieve optimal blending level resulting in unsmooth mouthfeel and nutrient loss

Engineering Contradiction:
Improveoperation simplicityVSAvoidblending optimization
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The food processing system performs self-monitoring and self-adjustment through integrated sensors and control algorithms. The system automatically detects when optimal blending is achieved and terminates the process, eliminating the need for user intervention or expertise while ensuring precise blending optimization.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Real-time sensor feedback enables the system to autonomously determine blending completion based on measured parameters (particle size, electrical conductivity, temperature). This automated feedback loop maintains ease of operation while achieving superior blending precision compared to traditional unmonitored processors.

Inventive Principle:
Principle #23Feedback
