Solution Overview

Problem

Existing devices for analyzing dough provide limited information, primarily focusing on the increase in volume of dough lumps, and do not effectively measure material properties such as viscosity and elasticity, which are crucial for understanding dough changes during production.

Innovation Solution

A device that applies a jet of pressurized fluid to the dough surface and uses a distance sensor to measure deformation, allowing for the determination of material properties like viscosity and elasticity by analyzing the development and removal of deformation using a mathematical deformation model, while maintaining a contactless analysis to prevent contamination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If contactless measurement is used to prevent contamination, then product purity is improved, but measurement precision is worsened due to inability to directly interact with the dough surface

Engineering Contradiction:
Improveproduct contaminationVSAvoidmaterial property measurement accuracy
Core Design Contradiction:
Loss of substanceVSMeasurement precision

Solution Approach 1:

A jet of pressurized fluid is introduced as an intermediary medium to transmit force to the dough surface from a contactless distance. The fluid jet serves as a mediator that bridges the gap between the non-contacting measurement device and the dough surface, enabling force application without direct mechanical contact while maintaining measurement capability through deformation observation

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces direct mechanical contact measurement systems with a combined fluid jet and optical/electronic distance measurement system. Instead of using physical probes that touch the dough, the system uses a fluid jet to apply force and a distance sensor to measure the resulting deformation, substituting mechanical contact with a hybrid fluid-optical approach

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

2Device complexity

If only volume increase measurement is performed, then device complexity is reduced, but information completeness is worsened by lacking material property data

Engineering Contradiction:
Improvemeasurement system simplicityVSAvoidmaterial property information
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The measurement device is designed to perform multiple functions: it can measure both volume increase (through distance measurements at different positions) and material properties (through controlled deformation measurements). The same fluid jet and distance sensor combination serves dual purposes, making the system universal rather than requiring separate specialized devices for each measurement type

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

3Measurement precision

If a jet of pressurized fluid is applied to measure deformation, then material property analysis is improved, but device complexity increases due to additional components

Engineering Contradiction:
Improvematerial property determination accuracyVSAvoidsystem component quantity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent merges the force application mechanism (fluid jet) with the measurement mechanism (distance sensor) into an integrated system. The fluid jet nozzle and distance sensor are positioned and coordinated to work together as a unified measurement assembly, reducing the need for separate independent systems for force application and deformation measurement

Inventive Principle:
Principle #5Merging (Combining)
