Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses face challenges in efficiently cooling and managing toner and ozone dispersion when only a subset of image forming units is in use.
Innovation Solution
The image forming apparatus is designed with a system that allows air supply and exhaust management based on the number of installed image forming units, ensuring efficient cooling and containment of toner and ozone when operating in full or specified specification states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If air supply and exhaust paths are designed for full specification state with all image forming units installed, then cooling performance is improved, but energy consumption increases when operating in specified specification state with fewer units
Solution Approach 1:
The air supply and exhaust paths are made dynamically adjustable based on the number of installed image forming units. When operating in specified specification state with fewer units, the system automatically adjusts the air paths to supply air only to stations with installed units, preventing energy waste from cooling empty stations while maintaining adequate cooling for active units.
Solution Approach 2:
The air supply system provides localized air flow to specific stations based on actual usage. Instead of uniformly supplying air to all stations regardless of whether image forming units are installed, the system directs air supply only to stations with installed units, optimizing energy efficiency while maintaining cooling performance where needed.
2Temperature
If air supply is provided to all stations regardless of image forming unit installation, then cooling coverage is improved, but toner scatter increases in unused stations
Solution Approach 1:
The air supply system dynamically adapts its configuration based on which stations have image forming units installed. When a station does not have an image forming unit, the air supply path to that station is automatically adjusted or closed, preventing toner from being dispersed into unused stations while maintaining cooling coverage for stations with active units.
Solution Approach 2:
The system extracts or removes air supply functionality from stations that do not have image forming units installed. By selectively disabling air supply to unused stations, the patent eliminates the harmful effect of toner scatter in those stations while preserving the beneficial cooling function for stations with installed units.
3Object-generated harmful factors
If air exhaust paths are configured for all stations, then ozone management is improved, but system complexity increases when operating with fewer image forming units
Solution Approach 1:
The air exhaust system is designed to dynamically configure exhaust paths based on the number and location of installed image forming units. When operating in specified specification state, the system automatically adjusts exhaust paths to match the active units, managing ozone effectively without requiring complex manual reconfiguration or increasing overall system complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enhances cooling performance, reduces toner scatter, and minimizes ozone dispersion, thereby improving operational efficiency and maintaining a cleaner working environment.
Implementation Method 1
Air is supplied to the plurality of stations through the plurality of air supply ports. The air supply duct causes air taken from an outside of a body of the image forming apparatus to flow toward the plurality of air supply ports.
Implementation Method 2
Air is exhausted from the plurality of stations through the plurality of exhaust ports. The exhaust duct causes air exhausted from the plurality of air exhaust ports to flow toward the outside of the body of the image forming apparatus.

AI summary
An image forming apparatus includes a plurality of image forming units, a plurality of stations, a plurality of air supply ports, and an air supply duct. When image formation is performed in a full specification state in which all of the image forming units are installed in the stations, air is supplied from all of the air supply ports to all of the stations. When image formation is performed in a specified specification state in which a station to be used in which one of the image forming units is installed and an unused station in which none of the image forming units is installed are present, air is supplied to the station to be used from an air supply port corresponding to the station to be used, and air is not supplied to and is not exhausted from the unused station via another air supply port.
