Exposure Unit Relay Wiring for Multi-Drum Image Forming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of wiring for control signals to multiple exposure units in image forming apparatuses is a challenge due to the increased number of signal lines, which complicates the structural arrangement and increases the risk of interference.
Innovation Solution
A relay unit is introduced on the main body surface to relay control signals to exposure portions, using a reception connector to receive signals from a controller and separate connectors to transmit them to individual exposure units, simplifying the wiring and reducing signal line complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple exposure units are provided for multiple photosensitive drums, then image forming capability is improved, but the number of signal lines increases and wiring becomes complicated
Solution Approach 1:
A relay unit is introduced as an intermediary component to receive control signals from the controller and distribute them to multiple exposure units. The relay unit includes a reception connector that receives control signals and multiple transmission connectors that transmit these signals to respective exposure units, thereby simplifying the overall wiring structure while maintaining the ability to control multiple exposure units
2Ease of operation
If the controller is arranged on the first surface and exposure units are inside the main body, then control functionality is improved, but signal transmission distance and wiring complexity increase
Solution Approach 1:
The relay unit serves as an intermediary that bridges the controller on the first surface and the exposure units inside the main body. By placing the relay unit strategically and using its reception and transmission connectors, control signals can be efficiently transmitted over the required distance without excessive wiring complexity
3Device complexity
If signal lines are wired directly from controller to each exposure unit, then control signal transmission is simplified, but the number of signal lines increases
Solution Approach 1:
The relay unit merges multiple signal transmission paths by receiving control signals through a single reception connector and then distributing them through multiple transmission connectors to respective exposure units. This consolidates the wiring structure, reducing the overall number of signal lines required while maintaining direct control signal transmission to each exposure unit
