Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If items are manually fed into the automatic packaging device, then the packaging device can process items, but items may be omitted or incorrect items may be included and operational capacity is reduced

Engineering Contradiction:
Improveaccuracy of item transferVSAvoidoperational capacity of packaging device
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent replaces the manual mechanical feeding process with an automated robotic system that uses vision guidance and automated picking mechanisms to transfer items from storage containers to the packaging device, eliminating human error and enabling continuous operation at full capacity

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

Solution Approach 2:

The system enables self-service through automated item identification, selection, and placement mechanisms that operate autonomously to feed the packaging device, ensuring accurate item transfer without manual intervention and maintaining full operational capacity

Inventive Principle:
Principle #25Self-service

2Productivity

If manual feeding is used, then flexibility in handling different items is maintained, but errors occur and efficiency is reduced

Engineering Contradiction:
Improveoperational efficiencyVSAvoidaccuracy of order fulfillment
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent incorporates vision systems and sensors that provide real-time feedback on item identification, location, and placement accuracy, allowing the automated system to detect and correct potential errors before they affect order fulfillment accuracy while maintaining high operational efficiency

Inventive Principle:
Principle #23Feedback

AI summary

An inventory handling apparatus for transferring inventory items from an inventory bin onto a conveyer includes a rotatable member with a conveyance assembly mounted inside. The conveyance assembly receives an inventory bin into a conveyance channel sized to restrain the inventory bin during inversion of the inventory bin. The inverted inventory bin is moved onto a conveyor and the inventory bin lifted thereby leaving the inventory items on the conveyor.
