Parabolic Dust Scanner Lighting for Floor Debris Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large areas such as offices, it is difficult for cleaners to identify and remove small foreign substances like dust due to their visibility under ceiling lighting, leading to reduced cleaning efficiency and increased re-cleaning efforts.
Innovation Solution
A dust scanner that projects light beams in parallel to the floor using LED lighting components and a transparent parabolic transmissive body, allowing foreign substances to be clearly identified through shadows and reflections, reducing the need for re-cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If ceiling lighting is used for cleaning, then the cleaning area can be covered, but small foreign substances like dust are difficult to identify
Solution Approach 1:
The patent applies local quality by using a separate low-positioned light source specifically for illuminating the floor surface where dust exists, rather than relying on general ceiling lighting. This localized lighting arrangement improves the visibility of small foreign substances in the specific area where cleaning is needed, while maintaining overall area coverage through the extended structure of the cleaning device.
2Productivity
If vacuum cleaning is performed first, then easily scattered dust is removed, but residual dust remains undetected
Solution Approach 1:
The patent implements preliminary action by illuminating the floor surface with a low-positioned light source before the cleaning operation to make residual dust visible. This allows the cleaner to identify and remove dust that would otherwise remain undetected after vacuum cleaning, thereby improving overall cleaning precision and reducing the need for re-cleaning.
3Reliability
If re-cleaning is performed in large areas, then cleaning completeness is improved, but working time increases
Solution Approach 1:
The patent applies feedback by providing real-time visual information about the presence of dust and foreign substances through specialized lighting. This allows the cleaner to immediately identify areas that need attention and adjust their cleaning actions accordingly, eliminating the need for time-consuming re-cleaning operations and ensuring cleaning completeness in a single pass.

Function Achieved in This Case
Improves cleaning efficiency by clearly identifying dust and debris, reducing the effort required for re-cleaning in large areas, enhancing the effectiveness of the cleaning process.
Implementation Method 1
a transmissive body including a parabolic surface having a vertical cross-section convex toward an outside, the transmissive body being formed to be transparent and configured to transmit light beams emitted from the plurality of LED lighting components located at an inside thereof to an outside
Implementation Method 2
each of the plurality of LED lighting components may be disposed at a focal point of the parabolic surface, the focal point being spaced apart from the transmissive body by a predetermined interval, whereby the light beams transmitted to the parabolic surface may be projected in parallel to a floor without spreading up and down
