System for temperature mapping in temperature-controlling storage units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current controlled temperature units (CTUs) face challenges in maintaining temperature uniformity and compliance due to issues like compressor inefficiency, frost buildup, poor airflow, and power failures, leading to costly and time-consuming requalification processes and potential product quality or safety risks.
Innovation Solution
A controlled temperature unit equipped with multiple temperature probes within the insulated chamber, connected to a process control unit (PCU) for continuous temperature monitoring and control, featuring a visual display for data management and alarm functions, allowing for self-validation and self-calibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external temperature mapping devices are used for commissioning and requalification, then temperature uniformity can be validated, but the process is time-consuming and requires frequent requalification
Solution Approach 1:
The patent applies preliminary action by installing multiple temperature probes during the initial commissioning phase to continuously monitor temperature distribution. This preliminary setup eliminates the need for repeated external mapping devices during requalification, as the already-installed probes provide ongoing validation data.
Solution Approach 2:
The system implements self-service through automated continuous monitoring by the temperature probes and PCU, which independently track and record temperature uniformity without requiring external intervention. This self-monitoring capability allows the CTU to validate its own performance continuously, replacing periodic manual requalification processes.
2Reliability
If multiple temperature probes are installed within the insulated chamber, then continuous temperature monitoring is achieved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the temperature monitoring function across multiple independent probes positioned at different locations within the insulated chamber. Each probe independently monitors its local temperature, and the PCU aggregates these readings to assess overall temperature uniformity, providing comprehensive coverage without requiring a single complex monitoring system.
3Reliability
If continuous temperature monitoring is implemented, then temperature uniformity can be maintained, but energy consumption increases
Solution Approach 1:
The patent replaces mechanical or manual temperature monitoring methods with electronic temperature probes and a PCU-based digital monitoring system. This substitution enables continuous automated monitoring with minimal energy consumption, as the electronic sensors and processing unit require significantly less power compared to manual measurement devices or frequent physical inspections.

AI summary
The various components of the controlled temperature unit allow the unit to control temperature and collect or manage temperature data. The controlled temperature unit may be equipped with multiple temperature probes, and data generated by these probes may be managed by a process control unit housed within the wall of the controlled temperature unit. The process control unit may then be operable to display temperature related data on a visual display attached to one of the exterior walls of the controlled temperature unit.
