Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing temperature-controlled shipping containers are unable to maintain varying temperature ranges within a single container, posing challenges in transporting perishable goods that require different temperature conditions during transit.
Innovation Solution
The active cryo container features multiple storage areas with independent temperature control, a control system that monitors and adjusts temperatures using a circulating fan and solid dry ice cooling, and includes visual and audible alarms for temperature deviations, powered by a removable battery or vehicle power supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single temperature-controlled container is used, then transportation simplicity is improved, but the ability to maintain different temperature ranges for different goods deteriorates
Solution Approach 1:
The container is divided into multiple independent storage chambers (first storage chamber, second storage chamber, third storage chamber) that can be separated or combined. Each chamber can be independently temperature-controlled, allowing different temperature ranges for different goods while maintaining a single container structure for simplified transportation.
Solution Approach 2:
The container incorporates movable divider walls and adjustable shelving that can be reconfigured based on cargo requirements. The chambers can be dynamically adjusted in size and position, and the container can transition between a unified configuration and separated configurations to adapt to different transportation needs.
2Adaptability or versatility
If multiple independent temperature zones are created, then temperature control flexibility is improved, but system complexity deteriorates
Solution Approach 1:
Multiple storage chambers are merged into a single integrated container structure with shared walls and coordinated temperature control systems. The chambers can function independently when different temperatures are needed, but can also be operated as a unified system when uniform temperature is sufficient, reducing operational complexity.
Solution Approach 2:
Each storage chamber is designed with multi-functional capabilities, serving as both a thermal insulation barrier and a structural element. The divider walls serve dual purposes as both separation barriers and thermal insulation layers, reducing the need for additional components and simplifying the overall system.
3Measurement precision
If active cooling systems are added, then temperature control precision is improved, but energy consumption deteriorates
Solution Approach 1:
The cooling system operates periodically rather than continuously, with temperature sensors monitoring each chamber and activating cooling only when temperature thresholds are exceeded. This on-demand operation maintains precise temperature control while minimizing energy consumption during stable temperature periods.
Solution Approach 2:
Temperature sensors in each storage chamber provide continuous feedback to the control system, which adjusts cooling activation and intensity based on real-time temperature conditions. This feedback mechanism ensures precise temperature maintenance while optimizing energy usage by cooling only when and where needed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the transportation of products at different temperatures from ambient to cryogenic levels, ensuring the integrity of goods by maintaining precise temperature control and alerting users to temperature excursions, thus extending the shelf life of perishable items.
Implementation Method 1
The bunker section contains a cooling vector material. In the preferred embodiment, this cooling vector material is solid dry ice. Solid dry ice cools the ambient air encompassing it, therefore reducing the temperature in said bunker section.
Implementation Method 2
Upon the activation of a circulating fan, cooling air is displaced from the bunker section to various material storage sections depending on thermal needs. This is accomplished by a circulating fan moving the warmer air internal to material storage sections down to bunker section 28.
