Solution Overview

Problem

Conventional color developing machines require winding and setting of print media into a roll form, making the process cumbersome and leading to a large device size when combined with ink jet printers, as they typically spread horizontally.

Innovation Solution

A color developing machine with a transportation path that intersects the horizontal direction, allowing for compact design, featuring heaters along the width of the path for optimized heating, a movable wall for maintenance, and an exhaust unit to efficiently discharge heated air, enabling independent heating control and reducing device size.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If the transportation path extends in the horizontal direction to accommodate the print medium, then the print medium can be transported through the color developing unit, but the device size becomes large

Engineering Contradiction:
Improvetransportation path lengthVSAvoiddevice footprint area
Core Design Contradiction:
Length of moving objectVSArea of stationary object

Solution Approach 1:

The patent changes the transportation path orientation from horizontal to vertical direction. The print medium is fed from a lower feed roller and transported upward through the heating unit to an upper discharge roller, eliminating the need for horizontal space while maintaining the necessary transportation path length for color development

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If the print medium is wound into a roll form and set on the feed roller, then the print medium can be fed into the color developing machine, but the operation becomes troublesome and time-consuming

Engineering Contradiction:
Improveprint medium feeding operationVSAvoidtime for winding and setting print medium
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent provides a feed roller that directly feeds the print medium from a reel in a continuous state without requiring the user to manually wind and set rolls. The feed roller is configured to automatically supply the print medium to the transportation path, eliminating preliminary manual preparation steps

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The feed roller system is designed to automatically handle the print medium supply from the reel, performing the feeding function without requiring user intervention for winding and setting operations. The system serves itself by maintaining continuous print medium supply through the automated feed mechanism

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If multiple heaters are arranged along the width direction of the print medium, then the heating control precision can be improved, but the device complexity increases

Engineering Contradiction:
Improveheating uniformity precisionVSAvoidheating control system complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The heating system is divided into multiple independent heater units arranged along the width direction of the print medium. Each heater can be independently controlled to provide precise temperature regulation across different zones, ensuring uniform heating while maintaining manageable system complexity through modular design

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different heaters positioned at different locations along the width direction can be controlled with different parameters to match the specific heating requirements of different regions of the print medium. This allows optimized heating control for each local area while maintaining overall system simplicity

Inventive Principle:
Principle #3Local quality

4Area of stationary object

If the color developing unit is compactly formed with vertical transportation path, then the device size is reduced, but the heated air discharge efficiency may be affected

Engineering Contradiction:
Improvedevice footprint areaVSAvoidheated air discharge efficiency
Core Design Contradiction:
Area of stationary objectVSProductivity

Solution Approach 1:

By orienting the transportation path vertically, the heated air naturally rises and can be efficiently discharged through the upper discharge roller area. This vertical arrangement utilizes gravitational and buoyant forces to facilitate air flow, maintaining high discharge efficiency while achieving compact horizontal footprint

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
