Light-Emitting Device Cleaning Transmission Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In light-emitting devices with multiple units, accessing the transmission part from a region in one direction is difficult due to increased distance, making it hard to transmit moving force effectively to the cleaning unit.
Innovation Solution
The design includes an extending part that elongates the transmission part, allowing easier access by positioning the cleaning unit furthest in the opposite direction, with the end of the extending part located further in that direction than the midpoint between the light-emitting units, facilitating the transmission of moving force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the transmission part is accessed from a region in the one direction with respect to the other light-emitting unit, then the distance to the transmission part is increased, but the transmission part cannot be easily accessed
Solution Approach 1:
The extending part projects from the transmission part in a direction substantially perpendicular to the one direction (the direction along which light-emitting units are arranged). This dimensional change allows access to the transmission part from the region between light-emitting units, effectively reducing the access distance by utilizing a different spatial dimension rather than extending along the existing linear arrangement.
2Ease of operation
If the end of the extending part is positioned further in the one direction than the midpoint between light-emitting units, then accessibility is improved, but the transmission path becomes longer
Solution Approach 1:
The transmission system is divided into two distinct components: the transmission part (which transmits moving force between light-emitting units) and the extending part (which provides access). This segmentation allows the extending part to be optimized for accessibility without unnecessarily increasing the length of the transmission part, as each component serves its specific function independently.
Solution Approach 2:
The extending part projects in a direction substantially perpendicular to the arrangement direction of light-emitting units. This orthogonal projection minimizes the increase in transmission path length while achieving the accessibility goal, as the extending part adds length in a different dimension rather than extending the linear transmission path.

AI summary
A light-emitting device includes: a first light-emitting unit that extends in one direction and that has a first emission surface that emits light located along the one direction; a second light-emitting unit that is located in the one direction with respect to the first light-emitting unit, that extends in the one direction, and that has a second emission surface that emits light located along the one direction; a cleaning unit that is capable of moving in the one direction and an opposite direction that is opposite to the one direction to clean the first emission surface; a transmission part that extends from the cleaning unit in the one direction and that transmits a moving force for moving the cleaning unit to the cleaning unit; and an extending part that extends from the transmission part in the one direction to elongate the transmission part. When the cleaning unit is positioned furthest in the opposite direction, an end of the extending part in the one direction is located further in the one direction than a midpoint between an end of the first light-emitting unit in the one direction and an end of the second light-emitting unit in the one direction.
