Solution Overview

Problem

Current return systems for food packaging lack automation and efficiency, relying on staff for manual handling and recording, which is inefficient and prone to errors, especially in ensuring proper disposal and preventing non-food packaging items from being returned.

Innovation Solution

An automatic return machine with a pivotably mounted input compartment, a locking mechanism controlled by a computer, and scanners for identification, along with a light barrier device to ensure proper disposal, allowing users to safely and efficiently return food packaging while preventing non-food items from being processed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual staff handling is used for returning food packaging, then flexibility and adaptability are maintained, but productivity and operational efficiency are reduced

Engineering Contradiction:
Improveoperational efficiencyVSAvoidautomation level
Core Design Contradiction:
ProductivityVSExtent of automation

Solution Approach 1:

The system enables self-service return of food packaging through automated identification and verification. Users independently insert packaging into the input compartment, and the system automatically scans, verifies, and processes the return without requiring staff intervention for each item.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Manual mechanical handling by staff is replaced with an automated system combining scanners, light barriers, and controlled compartment mechanisms. The physical action of staff accepting and recording returns is substituted with optical scanning and automated verification systems.

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

2Measurement precision

If manual recording systems are used, then system complexity is reduced, but measurement precision and reliability of return tracking are worsened

Engineering Contradiction:
Improvereturn tracking accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system incorporates feedback mechanisms where scanners detect packaging insertion, the computer verifies packaging type against return criteria, and the system provides confirmation to the user. This closed-loop feedback ensures accurate tracking and verification of returned packaging.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

A computer system acts as an intermediary between the physical packaging and the return record. The computer receives data from scanners, processes verification logic, and maintains accurate records, serving as a mediator that ensures precision without requiring complex manual procedures.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If no verification system is used, then ease of operation is improved, but reliability of preventing non-food items from being returned is reduced

Engineering Contradiction:
Improvepackaging verification reliabilityVSAvoidoperation simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system performs preliminary verification before completing the return process. Scanners scan the packaging before it is fully processed, and the computer verifies eligibility before allowing the return to be finalized, preventing non-food items from being accepted.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system takes preliminary anti-action by actively preventing non-food items from being returned through verification. The scanner and computer system work to identify and reject inappropriate items before they can be processed, countering potential errors before they occur.

Inventive Principle:
Principle #9Preliminary anti-action

4Reliability

If the input compartment is always accessible, then ease of operation is improved, but reliability of controlled return is reduced

Engineering Contradiction:
Improvecontrolled return reliabilityVSAvoidcompartment accessibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The input compartment transitions between locked and unlocked states dynamically based on the return process. The compartment is locked during verification to prevent removal, then unlocked to allow proper disposal, providing controlled accessibility that adapts to the operational stage.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system uses feedback from scanners and light barriers to control compartment locking. When packaging is detected and verified, the system provides feedback that triggers the locking mechanism to engage or disengage, ensuring the compartment is accessible only at appropriate stages of the return process.

Inventive Principle:
Principle #23Feedback
