Floor Unit Light Guide Layout for Multi-Edge Cleaning Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor cleaning devices, such as vacuum cleaners, lack optimal illumination of areas to the side and behind the nozzle, making it difficult for users to see dirty areas and assess cleaning results effectively.
Innovation Solution
The light output area of the light guide is arranged along the front, side, and rear edges of the floor unit, utilizing LEDs and optical fibers to provide continuous illumination around the cleaning path, enhanced by a reflector and lens for efficient light distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the light guide is only arranged at the front edge of the nozzle, then the structure is simple, but the illumination coverage is insufficient and areas to the side and behind the nozzle are not illuminated
Solution Approach 1:
The light guide is segmented into multiple sections arranged at different edges of the floor unit. Specifically, light guides are arranged at the front edge, side edges, and rear edge, dividing the illumination function across multiple locations to achieve comprehensive coverage while maintaining manageable complexity at each segment
Solution Approach 2:
The illumination is extended from a single-dimensional front-edge arrangement to a multi-dimensional configuration by adding light guides at side edges and rear edge, creating a circumferential illumination pattern that covers all areas around the floor unit
2Loss of information
If the light guide illuminates only the area directly in front of the nozzle, then the device complexity is low, but the visibility of dirty areas and cleaning results is insufficient
Solution Approach 1:
The visibility function is segmented by placing light guides at multiple edges (front, side, rear) to provide distributed illumination across the entire cleaning path, ensuring that both dirty areas ahead and cleaned areas behind remain visible
Solution Approach 2:
The light guides are positioned to illuminate areas before they are cleaned (front edge) and areas after cleaning (rear edge), providing continuous visibility of both the work ahead and the results achieved
