This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,496.

Summary of the Inventive Concept

This inventive concept adapts the original temperature-controlled shipper for specific, narrow markets or unique operational environments, providing reliable temperature control in extreme weather conditions, high-security needs, disaster relief, or remote areas.

Background and Problem Solved

The original patent disclosed a temperature-controlled shipper for shipping diagnostic blood sample vials, but it did not address the challenges of extreme weather conditions, high-security needs, disaster relief, or remote areas. The new inventive concept addresses these limitations by providing specialized temperature-controlled shippers that can maintain a specific temperature range for an extended period in these unique environments.

Detailed Description of the Inventive Concept

The new inventive concept comprises a temperature-controlled shipper with a dual phase change material liquid suspension, designed to operate in extreme weather conditions, high-security environments, disaster relief scenarios, or remote areas. The shipper includes features such as tamper-evident seals, GPS tracking devices, solar-powered refrigeration units, communication devices for real-time monitoring, thermal insulation layers, and shock-absorbing materials. These features enable the shipper to maintain a specific temperature range for an extended period, ensuring the integrity of temperature-sensitive products.

Novelty and Inventive Step

The new claims introduce novel features and combinations of features that are not present in the original patent. The inventive step lies in the adaptation of the original temperature-controlled shipper for specific, narrow markets or unique operational environments, providing a reliable and effective solution for temperature control in these environments.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include variations in the design of the shipper, such as using different materials, shapes, or sizes. Additionally, the inventive concept could be implemented using different phase change materials or combinations of materials. Other variations could include integrating additional features, such as sensors, alarms, or automated monitoring systems.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in industries such as pharmaceuticals, biotechnology, and medical devices, particularly in areas where temperature control is critical. The target markets include disaster relief organizations, remote healthcare providers, and companies operating in extreme weather conditions.
