Light-emitting device cleaning mechanism with shared transmission unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light-emitting devices require independent cleaning mechanisms for each emission surface, which complicates the cleaning process and increases maintenance complexity.
Innovation Solution
A light-emitting device structure that includes a first and second light-emitting unit with shared cleaning units, where a transmission unit extends from the cleaning units to transmit a moving force, allowing both emission surfaces to be cleaned simultaneously.

Engineering Contradiction Analysis
1Reliability
If independent cleaning mechanisms are provided for each emission surface, then each surface can be cleaned independently, but the device complexity and maintenance complexity increase
Solution Approach 1:
The patent combines multiple cleaning units into a single integrated cleaning mechanism that can simultaneously clean multiple emission surfaces. The cleaning units are merged into one coordinated system that moves together to clean both the first and second emission surfaces, reducing the number of independent mechanisms required while maintaining effective cleaning of each surface.
Solution Approach 2:
The cleaning mechanism is designed with multi-functionality to perform cleaning operations on multiple different emission surfaces using a single integrated system. The transmission unit enables the cleaning units to universally clean both the first light-emitting unit emission surface and the second light-emitting unit emission surface, making the cleaning mechanism adaptable to multiple cleaning tasks simultaneously.
2Ease of operation
If independent cleaning mechanisms are provided for each emission surface, then each surface can be cleaned independently, but maintenance complexity increases
Solution Approach 1:
By merging multiple cleaning units into one integrated mechanism with a shared transmission unit, the patent reduces the number of separate components that require maintenance. The combined structure allows for centralized maintenance operations while preserving the capability to clean each emission surface independently through the coordinated movement of the integrated cleaning units.
3Ease of operation
If separate cleaning mechanisms are used for first and second emission surfaces, then cleaning can be performed independently, but operational efficiency decreases
Solution Approach 1:
The patent merges multiple cleaning units into an integrated system that can operate simultaneously on multiple emission surfaces. This combination enables parallel cleaning operations where the first and second cleaning units work at the same time on their respective emission surfaces, significantly improving cleaning efficiency while maintaining independent control capability through the transmission unit.
Solution Approach 2:
The integrated cleaning mechanism with transmission unit enables continuous cleaning action across multiple emission surfaces simultaneously. The coordinated movement of the cleaning units ensures that cleaning operations continue without interruption on both the first and second emission surfaces, maximizing the productivity and efficiency of the cleaning process.
