Solution Overview

Problem

Current produce tracing systems for specialty crops face challenges in capturing fine-grained item traceability data at the harvesting location, particularly due to the reliance on manual labor and inefficiencies in data collection, which affects productivity and increases costs.

Innovation Solution

The implementation of a personal mobile data collection device (PMDC) that is hands-free and wearable, allowing harvest workers to collect and transmit data on location, item traceability, and environmental conditions wirelessly, synchronizing with a cloud-based system for aggregation and analysis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual labor is used for data collection at harvesting location, then traceability data can be captured, but productivity decreases and costs increase

Engineering Contradiction:
Improvetraceability data captureVSAvoidharvest productivity
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent replaces manual mechanical data collection methods with an automated electronic system. The PMDC device uses barcode scanners, GPS receivers, and wireless communications to automatically capture and transmit traceability data, eliminating the need for manual recording and processing while maintaining data accuracy.

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

Solution Approach 2:

The PMDC device is designed to be worn by harvest workers and automatically collects data without requiring separate manual intervention. The device self-activates upon detecting motion or specific conditions, automatically scans barcodes, records GPS location, and transmits data wirelessly, allowing the system to serve itself rather than requiring dedicated data collection personnel.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If data collection is performed at actual picking location, then fine-grained item traceability is achieved, but additional burden on harvest workers increases

Engineering Contradiction:
Improveitem traceability granularityVSAvoidharvest worker operation
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent merges the data collection function with the harvesting activity itself. The PMDC device combines barcode scanning, GPS tracking, and wireless communication capabilities into a single wearable unit that harvest workers already carry or wear, integrating data collection into the existing harvesting workflow without requiring separate actions or tools.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent replaces manual data recording operations with automated electronic capture. The barcode scanner automatically reads and records item identifiers, the GPS receiver automatically tracks location, and the wireless interface automatically transmits data, eliminating the need for workers to manually record or process traceability information.

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

3Ease of manufacture

If manual traceability systems are used, then implementation is simple, but data aggregation and analysis efficiency is low

Engineering Contradiction:
Improvesystem implementation simplicityVSAvoiddata aggregation time
Core Design Contradiction:
Ease of manufactureVSLoss of time

Solution Approach 1:

The patent implements continuous data transmission and processing. The PMDC device continuously collects traceability data and transmits it wirelessly in real-time or near-real-time to the central server, eliminating batch processing delays. The system maintains continuous operation throughout the harvesting process, ensuring data flows continuously without interruption or manual intervention.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The patent replaces manual data aggregation and analysis processes with automated electronic systems. The central server automatically receives, stores, and processes traceability data from multiple PMDC devices, using database systems and algorithms to aggregate and analyze data efficiently without requiring manual compilation or interpretation.

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