Pneumatic Sweeping System for Race-Track Production Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In industrial manufacturing plants, loose debris on the production line surface frequently obstructs vehicles, leading to production shutdowns, especially in race-track type production systems where a single obstruction can halt the entire line.
Innovation Solution
A pneumatic sweeping system that includes a cleaning station with sensors to detect the presence of work stations, nozzles to direct a stream of fluid across the surface, and a container to collect debris, ensuring continuous operation by removing impediments from the production line surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If workers manually monitor and remove debris from the production line surface, then debris can be removed, but production efficiency decreases and the risk of obstruction increases
Solution Approach 1:
The system enables self-service cleaning by equipping the work station with its own cleaning apparatus (nozzles, container, and control system). The work station automatically detects debris presence via sensors and activates nozzles to blow debris into its own container, eliminating the need for external workers to monitor and clean the production line surface continuously.
Solution Approach 2:
The cleaning system performs preliminary action by continuously monitoring the production line surface for debris and removing it before it can obstruct vehicles. The sensor system detects debris presence in advance, and the control system activates nozzles to blow debris into the container before it becomes a hazard to vehicle operation.
2Productivity
If a race-track type production line system is used to increase productivity, then output increases, but the impact of debris obstruction is amplified causing complete production shutdown
Solution Approach 1:
Each work station in the race-track production line is equipped with its own autonomous cleaning system that can detect and remove debris independently. This self-service capability ensures that debris does not accumulate and obstruct vehicles, preventing complete production shutdowns that would otherwise occur in interconnected race-track systems where one obstruction halts the entire line.
Solution Approach 2:
The production line is segmented into multiple independent work stations, each with its own cleaning system. This segmentation isolates debris removal operations to individual stations, preventing debris from affecting the entire production line. If one station experiences debris, only that local station is affected, not the whole race-track system.
3Reliability
If continuous cleaning of the production line surface is implemented to prevent obstruction, then vehicle obstruction risk decreases, but energy consumption increases
Solution Approach 1:
The cleaning system operates periodically rather than continuously. Sensors monitor the production line surface for debris presence, and the control system activates nozzles only when debris is detected. This periodic operation maintains reliable debris removal (preventing vehicle obstruction) while significantly reducing energy consumption compared to continuous cleaning operations.
Solution Approach 2:
The system incorporates feedback control through sensor systems that continuously monitor for debris presence. The control system receives feedback from sensors and adjusts nozzle operation accordingly - activating nozzles only when debris is detected and deactivating them when the surface is clear. This feedback mechanism ensures reliable obstruction prevention while optimizing energy consumption by avoiding unnecessary cleaning operations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively reduces the likelihood of vehicle obstruction and subsequent manufacturing stoppages by continuously removing loose impediments from the production line surface, maintaining production flow.
Implementation Method 1
The at least one nozzle may direct a stream of fluid from the at least one nozzle onto and across the upwardly facing surface and displacing any loose impediments from the upwardly facing surface into the container via the fluid directed across the upwardly facing surface

AI summary
A method and system for removing loose impediments from a surface in a manufacturing setting. The surface may be where a widget is processed. As the widget is processed, loose impediments may fall onto the surface. The surface may be transported to a cleaning station where at least one nozzle directs a stream of fluid onto the surface to displace the loose impediments. A container may be provided adjacent to the surface to receive the loose impediments displaced from the surface. The at least one nozzle may continuously direct the stream of fluid onto to surface so long as the surface is present at the cleaning station. When the surface is no longer present at the cleaning station, the at least one nozzle may be deactivated.
