Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the professional cleaning sector, there is a need to optimize complex cleaning tasks and improve logistics, process planning, and staff training, particularly in larger areas, where existing systems lack efficient movement and position determination for cleaning staff and devices, leading to inefficiencies and the requirement for constant supervision.
Innovation Solution
A cleaning system equipped with movement sensors, data transfer modules, and position determination devices, including inertial sensors, gyroscopes, GPS, and magnetic field strength sensors, allows for wireless data transmission and accurate tracking of cleaning utensils' movements and positions, enabling efficient logistics and training through real-time monitoring and feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional scheduling methods are used to track cleaning staff positions, then implementation is simple and low-cost, but real-time position determination and logistics optimization are insufficient
Solution Approach 1:
The cleaning device integrates multiple functions including motion sensing (accelerometer, gyroscope), position determination (GPS), and communication capabilities into a single universal platform. This multi-functional integration enables both simple tracking and complex motion analysis without requiring separate systems, resolving the contradiction between measurement precision and device complexity.
Solution Approach 2:
The system uses an intermediary evaluation device that receives data from multiple cleaning devices and processes the information centrally. This mediator handles the complex data fusion and analysis, allowing individual cleaning devices to remain relatively simple while achieving high-position determination accuracy through centralized processing.
2Reliability
If supervisors manually monitor cleaning activities to ensure correct procedures, then cleaning quality can be controlled, but supervision costs and time consumption increase
Solution Approach 1:
The system continuously monitors cleaning device motion through sensors and provides real-time feedback by comparing actual motion patterns against stored reference sequences. This automated feedback mechanism ensures cleaning quality control without requiring continuous human supervision, eliminating time loss while maintaining reliability.
Solution Approach 2:
The cleaning system performs self-monitoring and self-evaluation by automatically comparing its own motion patterns against predefined correct sequences. This self-service capability allows the system to ensure cleaning quality without external supervision, resolving the contradiction between reliability and time loss.
3Productivity
If detailed motion sequences are recorded and analyzed for training purposes, then training effectiveness improves, but data processing complexity and computational requirements increase
Solution Approach 1:
The system stores reference motion sequences in advance before actual cleaning tasks. During training and evaluation, these pre-stored references are directly compared with actual motion data, eliminating the need for complex real-time analysis and reducing data processing complexity while maintaining high training efficiency.
4Productivity
If wireless data transmission is implemented for real-time monitoring, then logistics optimization improves, but energy consumption increases
Solution Approach 1:
The system transmits data periodically rather than continuously, sending position and motion information at defined intervals to the evaluation device. This periodic transmission approach maintains logistics efficiency by providing regular updates while significantly reducing energy consumption compared to continuous transmission.
