Multiple Ink Dispensing System for Printers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image forming apparatuses face limitations in producing accurate colors due to limited gamut, frequent depletion of ink containers, and cumbersome replacement processes, leading to increased servicing needs and production downtime.
Innovation Solution
A multiple dispensing system that includes removable cartridges with a first dispensing system for small area coverage and a second dispensing system with a larger hopper for larger area coverage, allowing for increased color flexibility and reduced replacement frequency, featuring an ink transporting mechanism to support the second dispensing system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If ink containers are frequently replaced to maintain sufficient imaging media supply, then productivity is maintained, but loss of time and operational complexity increase due to frequent replacement and servicing
Solution Approach 1:
The imaging media supply system is segmented into multiple independent containers (first container, second container, third container) that can be independently managed. This allows the system to switch between containers as they deplete, extending the overall supply duration without requiring frequent complete replacements of all containers simultaneously.
Solution Approach 2:
Multiple containers are pre-loaded with imaging media before the main container is depleted. The system is configured to automatically or easily switch to backup containers when the primary container is exhausted, eliminating the need for waiting during refilling operations.
2Ease of operation
If service representatives are relied upon to refill and replace depleted ink containers, then ease of operation is improved, but loss of time and cost increase due to production halts
Solution Approach 1:
The system enables operators to perform container replacements independently without requiring service representatives. The multiple container configuration allows operators to simply remove the depleted container and install a fresh one, with the system automatically switching supply sources, thereby eliminating production halts for servicing.
Solution Approach 2:
Depleted containers are easily removed and replaced with fresh containers. The system is designed to accommodate rapid container exchanges, allowing operators to discard empty containers and load new ones without complex procedures or waiting for service personnel.
3Device complexity
If standard CMYK ink containers are used, then device complexity is minimized, but manufacturing precision of color reproduction deteriorates due to limited gamut
Solution Approach 1:
The imaging media supply system is designed to accommodate multiple types of containers (standard CMYK containers and custom color containers) within the same device architecture. This universal design allows the system to maintain simplicity while enabling enhanced color reproduction capabilities through the addition of specialized containers when needed.
Solution Approach 2:
The system dynamically adapts its imaging media supply configuration based on the specific print job requirements. Operators can select from different container types (standard CMYK or custom colors) depending on the job needs, allowing the system to optimize color accuracy without permanently increasing complexity.
4Loss of time
If reserve ink containers are added to extend imaging media supply, then loss of time for replacement is reduced, but device complexity increases due to hidden locations and additional components
Solution Approach 1:
The imaging media supply is divided into multiple independent containers that can be independently accessed and replaced. This segmentation allows the system to extend supply duration through multiple containers while maintaining relatively simple individual container designs and replacement procedures.
Solution Approach 2:
Additional containers are positioned in accessible locations within the device, allowing operators to easily reach and replace them without requiring complex internal mechanisms or hidden storage spaces. The containers are arranged in a manner that extends the supply timeline while remaining operationally simple.

AI summary
Systems and methods of a multiple dispensing system may include an image carrier, and may include a plurality of substantially aligned developing units positioned to develop image information on the image carrier. Each developing unit may include only one ink container and only one developer housing. The systems and method may also include a first dispensing system positioned upstream in a sheet feed direction of the plurality of substantially aligned developing units. The first dispensing system may include a first ink container and a first developer housing. The first developer housing may be configured to receive first imaging media from the first ink container and second imaging media from at least one other ink supply source.
