Optical Collector Localization Using Projected Ceiling Markers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing localization systems for monitoring the position of collectors within work areas, such as trolleys and shelves, are inefficient due to the need for complex installation, frequent maintenance, and high costs, especially when ceilings are irregular, and do not adapt well to changes in the work area layout.
Innovation Solution
A localization system using projectors to emit optical signals onto the ceiling, coupled with optical devices on collectors, which generate measurement signals for a control unit to determine precise positions without extensive ceiling installations, allowing scalability and reduced maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If graphic elements are applied to the ceiling of the work area, then localization coverage can be achieved, but installation time and cost increase significantly due to works at height and irregular ceiling shapes
Solution Approach 1:
The patent uses virtual copies (projected images) of graphic elements instead of physical applications. The projector creates optical representations of localization markers on the ceiling without requiring physical installation, thereby achieving localization coverage while eliminating installation time and cost associated with works at height
Solution Approach 2:
The patent replaces the mechanical process of applying physical graphic elements to the ceiling with an optical projection system. Instead of using adhesives, paints, or stickers that require manual application and drying time, the system uses a projector to generate virtual markers that can be instantly deployed and reconfigured
2Reliability
If graphic elements are applied to the ceiling, then localization can be performed, but the system becomes difficult to implement due to irregular ceiling shapes requiring adaptation of coupling mechanisms
Solution Approach 1:
The projector creates virtual copies of localization markers that can be projected onto any ceiling shape without requiring physical adaptation. The optical copies conform to the projected surface regardless of the ceiling's geometry, eliminating the need for custom coupling mechanisms for irregular surfaces
Solution Approach 2:
The projection system allows dynamic reconfiguration of localization markers without physical reinstallation. The virtual markers can be moved, resized, or reshaped through software control, adapting to irregular ceiling shapes and changing localization requirements without modifying the physical infrastructure
3Reliability
If physical graphic elements are used on the ceiling, then localization is achieved, but the system requires significant material and installation costs
Solution Approach 1:
The system uses optical copies projected by a digital projector instead of physical graphic elements. This eliminates material costs for paints, stickers, or printed films, and reduces installation costs by removing the need for specialized ceiling work, adhesives, and manual application labor
Solution Approach 2:
The projection system uses inexpensive, easily replaceable components (projector, software) compared to permanent ceiling installations. If the localization needs change, the entire system can be reconfigured without wasting physical materials, as the projected markers can be instantly modified or removed
