WISP-Embedded Slide for Temperature Logging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current slides lack the capability to track and log temperature exposure history, which is critical for specimen integrity and diagnosis, leading to potential misdiagnosis or damage due to unknown temperature and duration exposures during specimen processing in medical and research labs.
Innovation Solution
A temperature measuring and logging slide with a wireless identification and sensing platform (WISP) that captures and records temperature data in real-time, providing a unique identifier and allowing wireless communication of data for quality control, featuring a substrate made of laminated or tempered glass with embedded or attached WISP and temperature sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional slides without temperature tracking are used, then the slide structure remains simple and成本低, but temperature exposure history cannot be tracked leading to specimen damage and misdiagnosis
Solution Approach 1:
The WISP device is embedded within the slide substrate, nesting the temperature tracking functionality inside the existing slide structure. This allows the slide to gain temperature monitoring capabilities without requiring an external separate device, thus improving reliability while minimizing structural complexity
Solution Approach 2:
The slide equipped with WISP autonomously tracks and records its own temperature exposure history throughout the specimen processing chain. This self-monitoring capability ensures specimen integrity without requiring external intervention or manual temperature logging, resolving the contradiction between reliability and complexity
2Measurement precision
If temperature tracking is added to slides, then temperature logging accuracy is improved, but the slide becomes more complex and harder to manufacture
Solution Approach 1:
The WISP device is designed as a disposable component integrated into the slide, allowing for simplified manufacturing processes. The low cost of the WISP module enables its integration without significantly increasing manufacturing complexity, while providing accurate temperature logging throughout the specimen processing chain
3Loss of information
If WISP is embedded in the slide, then temperature data can be captured and communicated wirelessly, but the slide substrate must accommodate additional components
Solution Approach 1:
The WISP device combines the temperature sensor, data storage, and wireless communication capabilities into a single integrated unit that is embedded within the slide substrate. This merging of functions eliminates the need for separate components, allowing temperature data tracking without significantly increasing substrate structural complexity
