Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual packing methods are used, then packing flexibility is maintained, but packing efficiency and item safety deteriorate

Engineering Contradiction:
Improvepacking efficiencyVSAvoiditem safety
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent replaces manual mechanical packing operations with an automated system that uses machine learning models to determine optimal packing orders. The system automatically analyzes item characteristics and generates packing sequences, substituting human decision-making with computational algorithms that optimize both efficiency and item safety.

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

Solution Approach 2:

The system enables self-service packing by providing automated packing order recommendations that agents can follow independently. The machine learning model autonomously generates packing instructions based on item data, allowing the system to serve itself in optimizing the packing process without requiring expert human judgment for each packing decision.

Inventive Principle:
Principle #25Self-service

2Productivity

If automated packing systems are implemented, then packing efficiency improves, but system complexity increases

Engineering Contradiction:
Improvepacking speedVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary machine learning model that acts as a mediator between item data and packing decisions. This model simplifies the system architecture by centralizing the complex decision-making logic in a single computational component, rather than requiring complex mechanical automation hardware throughout the packing process.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system replaces complex mechanical automation with computational algorithms. Instead of implementing physically complex automated packing machines, the patent uses software-based machine learning models to provide intelligent packing guidance, reducing mechanical complexity while maintaining high packing speeds.

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

3Reliability

If optimal packing order is achieved, then item damage is reduced, but computation time increases

Engineering Contradiction:
Improveitem damage reductionVSAvoidcomputation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary computation by training machine learning models in advance on historical packing data. This preliminary training phase allows the model to learn optimal packing patterns beforehand, so that during actual packing operations, the system can quickly retrieve and apply pre-learned knowledge without performing complex real-time calculations for each item.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms where packing outcomes are continuously monitored and used to retrain and improve the machine learning model. This feedback loop allows the system to learn from actual packing results, progressively improving item protection strategies while optimizing computation efficiency through pattern recognition rather than exhaustive calculation.

Inventive Principle:
Principle #23Feedback

AI summary

An online system uses a trained machine-learning model for efficient packing of items. Upon receiving, from a device of an agent or a device of a source via a network, a signal indicating that a set of items are ready for packing, the online system applies the machine-learning model to identify, based at least in part on input data, a packing order for one or more items of the set of items. Based on the identified packing order for the one or more items, the online system generates a packing interface signal. The online system sends the packing interface signal, wherein sending the packing interface signal causes the one or more items to be packed according to the identified packing order. This process is repeated until it is confirmed that all items from the set of items were packed.
