Solution Overview

Problem

Molds used in food product manufacturing face challenges such as mechanical, thermal, and chemical stress, leading to fatigue and potential contamination of products, resulting in costly delays and increased safety measures due to empirical design and lack of real-time monitoring capabilities.

Innovation Solution

A mold equipped with a measurement unit that includes sensors to collect and transfer data on mechanical parameters like stress, strain, and acceleration, allowing for real-time monitoring and optimization of the mold design and production process, enabling early detection of potential failures and improved hygiene.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If molds are designed with high safety factors to avoid failures, then reliability is improved, but the mold size increases and becomes heavier and harder to move

Engineering Contradiction:
Improvemold failure resistanceVSAvoidmold weight
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

The patent applies preliminary action by installing sensors and measurement units on the mold before production begins. These devices continuously monitor mechanical parameters such as stress, strain, and acceleration, allowing the actual load conditions to be measured in advance. This enables optimization of the mold design based on real data rather than conservative estimates, potentially reducing unnecessary weight while maintaining reliability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback mechanisms through sensors that continuously monitor the mold's mechanical state during production. The measured data on stress, strain, and acceleration is processed to provide feedback on actual load conditions. This feedback loop enables dynamic adjustment of safety factors and optimization of mold design, allowing for lighter molds that maintain adequate reliability based on actual performance data rather than worst-case assumptions.

Inventive Principle:
Principle #23Feedback

2Device complexity

If molds are designed without detailed knowledge of loads and environmental influences, then device complexity is reduced, but reliability deteriorates due to empirical design

Engineering Contradiction:
Improvedesign complexityVSAvoidmold integrity
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent introduces measurement units and sensors as intermediary devices between the mold and the design optimization process. These intermediaries collect real data on mechanical parameters, environmental conditions, and production processes. The data from these intermediaries is then used to refine the mold design, creating a bridge between empirical observations and theoretical design optimization, thereby improving reliability without excessive complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces empirical mechanical design methods with data-driven optimization. Instead of relying on conservative safety factors and empirical rules, the system uses sensor data to actually measure the mechanical loads and environmental influences. This substitution of empirical design with measured data enables more precise and reliable mold design while reducing unnecessary complexity.

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

3Reliability

If real-time monitoring of mold parameters is implemented, then reliability is improved through early detection of failures, but device complexity increases

Engineering Contradiction:
Improvefailure detection capabilityVSAvoidmonitoring system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the monitoring system into separate functional components: sensors for measuring mechanical parameters, data processing units for analyzing the information, and alert systems for detecting failures. This modular segmentation allows each component to be optimized independently and facilitates easier implementation and maintenance, reducing overall system complexity while maintaining high reliability through comprehensive monitoring.

Inventive Principle:
Principle #1Segmentation

4Reliability

If production is halted to check for chipped-off material, then safety is improved, but productivity decreases

Engineering Contradiction:
Improvefood safetyVSAvoidproduction speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent applies preliminary action by continuously monitoring mold integrity through sensors during production. The system detects signs of material degradation or chipping in real-time, allowing preventive measures to be taken before actual contamination occurs. This enables production to continue uninterrupted while maintaining food safety, as the system proactively identifies and addresses potential issues before they become problems requiring production halts.

Inventive Principle:
Principle #10Preliminary action
