Solution Overview

Problem

Current imaging systems require labor-intensive and time-consuming manual or external cutting processes to trim media to the appropriate size, which can be costly and inefficient, especially when dealing with media of varying sizes or after imaging operations.

Innovation Solution

Integration of a cutting module within the imaging device, comprising a housing, cutter, and drive system, allowing for automatic cutting of media to the desired size within the device, eliminating the need for pre-cutting or separate cutting devices, and enabling the cutting module to be stowed out of the media path when not in use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual or external cutting processes are used to trim media, then media can be trimmed to appropriate size, but labor and time costs increase

Engineering Contradiction:
Improvemedia trimming operationVSAvoidcutting process time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent combines the cutting function with the imaging device by integrating a cutting module that includes a cutter and drive system directly into the device. This merging eliminates the need for separate manual or external cutting processes, allowing media to be automatically trimmed to the desired size within the imaging device itself, thereby reducing labor and time costs while maintaining ease of operation

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The imaging device performs its own media cutting operation through the integrated cutting module, eliminating the need for external assistance or separate cutting equipment. The drive system automatically advances the media and the cutter trims it to the appropriate size, enabling the device to serve itself in the media preparation process

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If separate cutting devices are used for media trimming, then cutting function is provided, but device complexity and cost increase

Engineering Contradiction:
Improvemedia cutting capabilityVSAvoidsystem configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cutting module is integrated directly into the imaging device structure, combining the cutting function with the existing media handling system. The cutter and drive system are positioned to work with the media path already established in the device, eliminating the need for separate cutting equipment and reducing overall system complexity while maintaining adaptability for media cutting

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The imaging device is enhanced to perform multiple functions - both imaging operations and media cutting - through the integrated cutting module. This multi-functionality allows the same device to handle both the primary imaging task and the secondary media trimming task, reducing the need for additional specialized equipment

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If cutting module is always in media path, then cutting operation is available, but media path is blocked when cutting is not needed

Engineering Contradiction:
Improvecutting operation availabilityVSAvoidmedia flow
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The cutting module is designed with movable components that can dynamically adjust its position. The cutter and associated components can be retracted or moved out of the media path when cutting operations are not required, and positioned into the media path when cutting is needed. This dynamic positioning ensures continuous media flow during non-cutting operations while maintaining cutting capability when required

Inventive Principle:
Principle #15Dynamics

AI summary

In an example, a cutting module may comprise a housing to engage the cutting module with a drive shaft, a cutter engaged with the housing, and a drive system engaged with the housing. The cutting module may be movable along the drive shaft laterally to a media path, the cutter may cut media along the media path, and the drive system may lock when the drive shaft rotates in a second drive direction such that the cutting module moves with the drive shaft.
