Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Efficient operation of analytical devices in a pool, such as chromatographic sample separation apparatuses, is challenging due to uneven wear and tear, leading to arbitrary maintenance times and high maintenance efforts.
Innovation Solution
A method and control unit for allocating functional tasks to analytical devices based on predefined control targets, such as balancing wear and tear, to coordinate maintenance and optimize resource utilization, including predicting maintenance times and allocating tasks to achieve synchronized maintenance schedules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If analytical devices are operated in a pool without systematic allocation, then device utilization appears simple and flexible, but wear and tear becomes uneven leading to arbitrary maintenance times and high maintenance efforts
Solution Approach 1:
The system changes the parameter of task allocation from random/manual assignment to controlled assignment based on wear and tear parameters. The control unit monitors usage parameters of each device and dynamically adjusts task allocation to balance wear accumulation across devices, transforming maintenance from an arbitrary process to a parameter-driven controlled process.
Solution Approach 2:
The system implements feedback by continuously monitoring the usage and wear status of analytical devices, then using this information to adjust future task allocations. The control unit receives feedback on device condition and modifies allocation decisions to prevent any single device from accumulating excessive wear, thereby coordinating maintenance needs across the device pool.
2Productivity
If tasks are allocated without considering wear and tear, then allocation process is simple and quick, but maintenance times become unsynchronized increasing overall maintenance effort
Solution Approach 1:
The system performs preliminary action by predicting future wear and maintenance needs based on current task allocation patterns. The control unit calculates projected maintenance times in advance and adjusts task allocations proactively to synchronize maintenance schedules, preventing situations where multiple devices require maintenance simultaneously and thereby reducing total downtime.
3Adaptability or versatility
If analytical devices are used arbitrarily, then operational flexibility is maintained, but device lifespan is reduced due to uneven wear and tear
Solution Approach 1:
The system enables self-service by allowing the control unit to automatically monitor device wear and reallocate tasks without external intervention. This automated wear-balancing mechanism extends device lifespans by preventing any single device from being overused, while maintaining operational flexibility through dynamic, rules-based task redistribution rather than rigid scheduling.

AI summary
In a method of allocating a plurality of functional tasks to a plurality of functional devices each capable of carrying out one or more of the functional tasks, the functional devices are analytical devices and each of the functional tasks corresponds to a respective predefined process related to analyzing a respective sample by a respective one of the functional devices. The functional tasks are allocated to the functional devices based on a criterion to achieve compliance with at least one predefined control target of controlling the functional devices.
