Solution Overview

Problem

Existing print apparatuses face issues with establishing a reliable electrical connection between print material containers and components, which can lead to data transmission failures and inefficient material transfer during printing operations.

Innovation Solution

The implementation of a guide structure with a guideway and recess system that assists in forming an electrical connection by guiding the print material container's rotation, ensuring secure electrical contact and material transfer between the container and the print component.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a guide structure with guideway and recess system is implemented to guide the print material container's rotation, then the reliability of electrical connection is improved, but the device complexity increases

Engineering Contradiction:
Improveelectrical connection reliabilityVSAvoidguide structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The guide structure acts as an intermediary mechanical system between the print material container and the print component. It includes a guideway that receives a protrusion from the container and a recess that guides the rotation movement, ensuring the electrical contact on the container properly aligns with the electrical contact on the print component during the rotation operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the print material container is designed to rotate within a recess guided by a guideway, then the ease of operation is improved, but the manufacturing precision requirements increase

Engineering Contradiction:
Improvecontainer rotation easeVSAvoidguideway and recess alignment precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The guide structure performs preliminary alignment actions before the electrical connection is established. The guideway receives the protrusion and guides the rotation movement in advance, ensuring that the electrical contact on the container is properly positioned relative to the electrical contact on the print component before contact is made.

Inventive Principle:
Principle #10Preliminary action

AI summary

In an example, a print component includes a guide structure. The example guide structure includes a recess to receive a print material container and a guideway with a guide wall to support rotation of the print material container. Upon rotation of the print material container, an electrical contact of the print material container moves towards an electrical contact coupled to the guide structure of the print component. In another example, a container includes a housing, a material transfer interface, and a mechanical interface. In that example, the mechanical interface includes a guide structure that defines a protrusion and a guideway to allow the container to rotate within a recess defined by a receptacle shell. Upon rotation of the container, an electrical contact coupled to the guide structure moves towards an electrical contact on the receptacle shell.
