Innovation Solution

A print interface system with multiple feed paths, a positionable diverter, and a controller that directs sheet material between a staging tray and a downstream module, allowing for independent printer operation and harmonious interaction with mailpiece inserters, including duplex printing capabilities without altering the printer's internal code.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a printer is integrated with a mailpiece inserter to enable on-demand printing, then productivity is improved, but device complexity increases

Engineering Contradiction:
Improveon-demand printing capabilityVSAvoidintegration complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

A print interface system is introduced as an intermediary component between the printer and the mailpiece inserter. This interface system manages the complexity of integration by providing standardized communication protocols and control mechanisms, allowing the printer to operate independently while still enabling on-demand printing functionality. The interface system acts as a mediator that coordinates between the printing device and the sheet handling equipment without requiring deep integration of internal systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of repair

If the printer operates independently without modifying internal program code, then ease of repair is improved, but adaptability worsens

Engineering Contradiction:
Improveprinter independenceVSAvoidoperating mode flexibility
Core Design Contradiction:
Ease of repairVSAdaptability or versatility

Solution Approach 1:

The system is divided into separate functional modules: the printer operates as an independent unit with its own control logic, while the mailpiece inserter has separate control for sheet handling. The print interface system provides standardized control signals to the printer without requiring modification of its internal program code. This segmentation allows each component to be repaired and maintained independently while still achieving coordinated operation through the standardized interface protocols.

Inventive Principle:
Principle #1Segmentation

3Productivity

If multiple feed paths are implemented for duplex printing, then productivity is improved, but device complexity increases

Engineering Contradiction:
Improveduplex printing throughputVSAvoidfeed path configuration
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The feed path configuration is made dynamic through the use of positionable diverters that can be repositioned based on printing requirements. For single-sided printing, sheets follow one feed path, while for duplex printing, the diverter redirects sheets to the appropriate feed path for back-siding. This dynamic reconfiguration capability allows the system to handle multiple operating modes without requiring permanent complex infrastructure, as the diverters can adapt their position based on the current printing task.

Inventive Principle:
Principle #15Dynamics

AI summary

A print interface system including a printer integrated in combination with a sheet handling system such as a mailpiece inserter. The print interface system facilitates the handling of sheet material in various operating modes, including conventional printing, duplex printing, and mailpiece creation modes. The system includes a printer having multiple feed paths for printing on opposing face surfaces of a sheet material. One of the feed paths directs sheet material to a staging tray and another feed path directs sheet material to a downstream module of the sheet handling system. The system further includes a positionable diverter for directing sheet material to one of the feed paths and a sheet sensor for determining when a sheet of material has been directed along the feed path leading to the output tray. A controller is operative to alternately reposition the diverter from one of two positions. A first position directs sheet material to the staging tray following a first print operation, and a second position directs sheet material to the downstream module of the sheet handling system. The controller, furthermore, repositions the diverter following a threshold period of time from receipt of the staging signal issued by the sheet sensor.
