Solution Overview

Problem

Existing temperature control devices for containers are not simple and reliable enough to maintain a predetermined temperature, especially in sterile environments where precise temperature control is crucial for biochemical reactions.

Innovation Solution

A flexible temperature control device with heating and cooling areas that can be deformed to fit snugly on a container, using heating elements like resistors or Peltier elements, and cooling elements with fluid lines, allowing for precise temperature control with minimal temperature deviation (less than 1°C) by making thermal contact with the container.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If heating or cooling elements protrude into the interior of the container to contact the fluid directly, then temperature control precision is improved, but the device complexity and risk of contamination increase

Engineering Contradiction:
Improvetemperature control precisionVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent uses the container wall as an intermediary medium to transfer heat between the heating/cooling elements and the fluid. The heating and cooling elements are positioned on the outer surface of the container wall, which acts as a thermal conduit to indirectly heat or cool the fluid inside, eliminating the need for elements to protrude into the container interior.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The heating and cooling elements are designed as flexible elements that can conform to the outer surface of the container wall. This flexible design allows intimate thermal contact with the container wall while maintaining simplicity in structure, enabling precise temperature control without complex internal mechanisms.

Inventive Principle:
Principle #30Flexible shells and thin films

2Device complexity

If heating and cooling elements are positioned on the outer surface of the container, then device simplicity is improved, but thermal contact efficiency deteriorates

Engineering Contradiction:
Improvedevice simplicityVSAvoidthermal contact efficiency
Core Design Contradiction:
Device complexityVSLoss of energy

Solution Approach 1:

The heating and cooling elements are designed as flexible elements that can be pressed against the outer surface of the container wall to ensure intimate thermal contact. This flexibility allows the elements to conform to the container's shape and maintain efficient thermal coupling without requiring complex mechanical pressure systems.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The system uses the container wall itself as the thermal contact medium, eliminating the need for separate thermal coupling mechanisms. The wall serves dual purposes: containing the fluid and facilitating heat transfer from the externally positioned heating/cooling elements, thereby simplifying the overall device structure while maintaining thermal efficiency.

Inventive Principle:
Principle #25Self-service

3Stability of the object's composition

If the temperature control device is rigid, then structural stability is improved, but adaptability to different container shapes deteriorates

Engineering Contradiction:
Improvestructural stabilityVSAvoidadaptability to container shapes
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The heating and cooling elements are designed as flexible components that can conform to various container shapes and sizes. This flexibility is achieved through using flexible materials or structures that can bend and adapt to the outer surface geometry of different containers while maintaining thermal contact, thereby providing universal applicability across diverse container types.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The temperature control device transitions from a static rigid structure to a dynamic flexible system that can adapt its shape. The flexible elements allow the device to dynamically adjust its configuration to match different container geometries, enabling a single device design to serve multiple container types effectively.

Inventive Principle:
Principle #15Dynamics
