Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for preparing transport containers for temperature-sensitive cargo lack flexibility in accommodating extended transfer time periods between fitting and filling, which can lead to temperature deviations outside the target range, necessitating restrictive filling timelines.
Innovation Solution
Incorporating supplementary energy storage elements with adjustable heat capacity to ensure the target temperature range is maintained during the transfer time period, which can be set based on expected delays, and these elements can be removed or reused as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the transport container is prepared with latent heat storage elements fitted at a given location, then the target temperature range is achieved quickly, but the method lacks flexibility for extended transfer time periods between fitting and filling
Solution Approach 1:
The system transitions from a static heat capacity configuration to a dynamic one by introducing supplementary energy storage elements that can be adjusted based on the expected transfer time period. The total heat capacity becomes variable rather than fixed, allowing adaptation to different operational scenarios while maintaining temperature control reliability.
Solution Approach 2:
The heat capacity is divided into two independent segments: main latent heat storage elements for the target time period and supplementary energy storage elements for the transfer time period. This segmentation allows each component to be optimized and adjusted independently, providing flexibility in managing different time periods between fitting and filling operations.
2Duration of action of stationary object
If the accommodation space is fitted with main latent heat storage elements for the target time period, then temperature control is ensured for the intended duration, but additional time periods for transfer cannot be accommodated
Solution Approach 1:
The supplementary energy storage elements are pre-positioned in the accommodation space during the fitting phase, alongside the main latent heat storage elements. This preliminary preparation ensures that when the transfer time period extends beyond expectations, the additional heat capacity is already in place to bridge the time gap without compromising temperature control.
Solution Approach 2:
The system changes the heat capacity parameter dynamically by activating supplementary energy storage elements based on the actual transfer time period. This parameter adjustment allows the system to extend its operational duration beyond the originally designed target time period while maintaining the required temperature range.
3Stability of the object's composition
If the transport container uses conventional thermal insulation and latent heat storage elements, then temperature stability is maintained, but the system cannot adapt to variable transfer time periods
Solution Approach 1:
The supplementary energy storage elements serve multiple functions: they can be used to extend the operational duration for extended transfer periods, provide additional thermal buffer capacity, and be removed or adjusted based on actual needs. This multi-functionality allows the system to maintain temperature stability while adapting to various transfer time scenarios.

Function Achieved in This Case
This approach enhances flexibility by ensuring the target temperature range is maintained throughout the extended transfer period, reducing the risk of temperature deviations and providing a more flexible preparation method for transport containers.
Implementation Method 1
latent heat storage elements having been preconditioned to a specific temperature—the target temperature. This temperature is maintained by latent heat storage elements during the phase transition with little deviation.
Implementation Method 2
This temperature is maintained by latent heat storage elements during the phase transition with little deviation.
Implementation Method 3
The thermal insulation for the accommodation space can be achieved in any conventional way. The use of vacuum insulation panels as a component of thermal insulation is particularly expedient.

AI summary
The invention relates to a method for preparing a transport container which has an accommodation space for goods to be transported, said accommodation space being insulated by external thermal insulation. At an equipment site, the accommodation space is equipped with preconditioned, main latent heat storage elements necessary for a target heat capacity. In addition to the preconditioned, main latent heat storage elements, the accommodation space is also equipped with further thermal energy storage elements, the auxiliary energy storage elements, which are preconditioned to a specified temperature. This means that a longer transfer time period can be allowed after equipping and before filling the accommodation space with the goods to be transported, such that, from the filling time, the full target time period within the desired target temperature range is available for transporting the goods to be transported.
