Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining the centrifugation status of biological samples are prone to errors, particularly in laboratories that do not integrate centrifugation data into their IT systems, leading to potential damage from unnecessary centrifugation steps and misinterpretation of natural sedimentation effects.
Innovation Solution
A g-force sensitive label attached to sample tubes that changes its physical state upon application of a centrifugal force above a threshold, allowing for machine-readable indication of centrifugation status, enabling accurate determination of centrifugation through a reading device and subsequent analytical processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If image-systems are used to determine centrifugation status, then automation is improved, but measurement precision deteriorates due to inability to distinguish natural sedimentation from centrifugation effects
Solution Approach 1:
A g-force sensitive label is introduced as an intermediary element that attaches to the sample tube and physically responds to centrifugal force through a visible state change. This label acts as a mediator between the centrifugation process and the detection system, providing unambiguous visual indication of actual g-force application rather than relying on indirect optical detection of sample characteristics.
Solution Approach 2:
The g-force sensitive label utilizes color change or visible pattern transformation in response to applied g-force. The label contains materials or structures that undergo measurable physical or optical changes when subjected to centrifugal acceleration, enabling clear visual or machine-readable distinction between centrifuged and non-centrifuged states regardless of natural sedimentation in the sample.
2Device complexity
If IT systems are used to track centrifugation status, then device complexity is reduced, but reliability deteriorates due to lack of integrated centrifugation data in many laboratories
Solution Approach 1:
The sample tube system becomes self-documenting through the g-force sensitive label, which automatically records and displays centrifugation status without requiring external data input or system integration. The label itself carries the centrifugation history information, making the sample container self-sufficient for status tracking and eliminating dependence on laboratory IT system configurations.
Solution Approach 2:
The g-force sensitive label is pre-attached to the sample tube before centrifugation, preparing the system to automatically indicate centrifugation status. This preliminary preparation ensures that the detection mechanism is already in place and requires no additional setup, data entry, or system configuration during the centrifugation process or afterward.
3Device complexity
If manual determination of centrifugation status is used, then device complexity is minimized, but productivity deteriorates due to time-consuming manual assessment
Solution Approach 1:
The g-force sensitive label provides immediate visual indication of centrifugation status through color change or pattern transformation, enabling instant determination without time-consuming manual assessment. The visible state change occurs during or immediately after centrifugation, allowing rapid identification of processed samples.
Solution Approach 2:
The manual visual inspection of sample characteristics is replaced by a dedicated g-force sensitive label designed specifically for status indication. This specialized component substitutes the complex manual assessment process with a simple, direct visual or machine-readable signal that requires minimal interpretation time.

AI summary
A g-force-sensitive label for detecting and indicating the application of a g-force is provided, the g-force sensitive label comprising an area for detecting and indicating an application of a g-force above a threshold value on the g-force sensitive label and an attachment area for attaching the g-force sensitive label on an object. At least one physical property of the area measurably changes its state upon applying a g-force above the threshold value, thereby altering a displayed pattern such that a machine-readable 1 D or 2D or alphanumeric code is displayed.
