Solution Overview

Problem

Conveyor systems processing bulk food products face challenges in ensuring uniform processing, particularly in achieving minimum temperature levels across the depth of the product bed, leading to inefficiencies and quality issues due to overprocessing.

Innovation Solution

Integration of sensors with adjustable probes into the conveyor belt to detect conditions within the product layer, allowing for precise measurement and adjustment of sensor height to monitor critical depths, enabling accurate control of processing conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If sensors are embedded in the conveyor belt to measure product conditions, then processing uniformity is improved, but measurement precision deteriorates when the product layer increases in depth

Engineering Contradiction:
Improveprocessing uniformityVSAvoidmeasurement precision
Core Design Contradiction:
Stability of the object's compositionVSMeasurement precision

Solution Approach 1:

The sensor probe height is made adjustable rather than fixed, allowing dynamic adaptation to different product layer depths. The probe can be positioned at optimal heights to measure conditions at critical depths within the product mass, maintaining measurement precision regardless of layer thickness variations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The measurement parameters are changed by adjusting the sensor probe's physical position (height above conveying surface) to match the product layer depth. This allows the sensor to measure at the appropriate depth position within the product mass, ensuring accurate readings even when layer depth varies.

Inventive Principle:
Principle #35Parameter changes

2Loss of energy

If the product mass depth is increased to improve processing uniformity, then energy waste from overprocessing is reduced, but measurement precision deteriorates

Engineering Contradiction:
Improveenergy wasteVSAvoidmeasurement precision
Core Design Contradiction:
Loss of energyVSMeasurement precision

Solution Approach 1:

The adjustable probe height allows the measurement system to adapt to increased product mass depth. By extending the probe deeper into the product layer, accurate temperature measurements can be obtained at the cold spot location even when the product bed is thicker, enabling energy-efficient processing without sacrificing measurement accuracy.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If a fixed sensor height is used to simplify the device structure, then device complexity is reduced, but adaptability to different product layer depths deteriorates

Engineering Contradiction:
Improvedevice complexityVSAvoidadaptability to product layer depth
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The sensor probe incorporates an adjustable height mechanism that allows it to be positioned at different depths above the conveying surface. This provides adaptability to various product layer depths while maintaining a relatively simple overall device structure, avoiding the need for complex multi-sensor arrays or extensive mechanical systems.

Inventive Principle:
Principle #15Dynamics

AI summary

A conveyor belt having a sensor probe extending upward from an outer conveying surface into a mat of bulk products conveyed on the belt. The probe senses a condition of the product mat at a predetermined depth. The probe height above the conveying surface may be fixed or may be adjustable to be positioned at a critical depth within the product mat.
