Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing product transport containers fail to effectively control temperature within the desired range of −40° C. to 4° C., leading to inefficiencies and increased costs due to oversized refrigerated loads and inadequate temperature maintenance during long transport durations.
Innovation Solution
A product transport container with an adjustable heat dissipation system, where the heat energy emitted by the refrigerated load and the thermal diffusion coefficient of the divider wall are optimized to match the heat dissipation of the container, allowing precise temperature control within the compartment, and the container's design includes a pivoting cover and divider wall for efficient loading and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the container uses a fixed insulating structure with standard refrigerated load, then the container can be manufactured simply, but the temperature control precision deteriorates and cannot maintain desired temperature range for long transport durations
Solution Approach 1:
The patent applies the dynamics principle by making the divider wall movable rather than fixed. The divider wall can pivot between a first position (for loading refrigerated load) and a second position (for sealing the chamber), allowing the container to adapt its configuration dynamically. This resolves the contradiction by enabling precise temperature control through adjustable refrigerated load positioning while maintaining manufacturing simplicity through a single movable component rather than complex active control systems.
Solution Approach 2:
The patent applies parameter changes by adjusting the thermal diffusion coefficient of the divider wall and the heat energy emitted by the refrigerated load to match the heat dissipation characteristics of the box. This optimization allows precise temperature control within the compartment by balancing heat transfer parameters, resolving the contradiction between temperature precision and structural complexity without requiring active control mechanisms.
2Reliability
If the refrigerated load is made oversized to ensure sufficient cooling, then temperature maintenance is improved, but material waste increases and cost price rises
Solution Approach 1:
The patent applies local quality by positioning the refrigerated load specifically against the diffusing divider wall in the chamber, rather than distributing it uniformly or using excess load. The divider wall's thermal diffusion properties are optimized to distribute heat evenly from the localized refrigerated load position, ensuring reliable temperature maintenance with minimal refrigerated load quantity, thus reducing waste and cost.
3Adaptability or versatility
If the container is designed for broad temperature range (−40° C. to −18° C.), then frozen product storage is effective, but maintaining narrower temperature range (0° C. to 4° C.) becomes difficult or impossible
Solution Approach 1:
The patent applies dynamics by enabling the divider wall to pivot between positions, which allows adjustment of the chamber volume and refrigerated load positioning. This dynamic configuration enables the container to optimize thermal characteristics for different temperature requirements - whether broad range for frozen products or narrow range for fresh products - resolving the contradiction between versatility and temperature precision.
Solution Approach 2:
The patent applies parameter changes by optimizing the thermal diffusion coefficient of the divider wall and the heat energy of the refrigerated load to match the box's heat dissipation characteristics. This parameter optimization allows the container to maintain precise temperature control for narrow ranges (0° C. to 4° C.) while retaining the capability for broader temperature ranges, resolving the contradiction between adaptability and temperature precision.
4Productivity
If the container uses a fixed sealed structure, then manufacturing is simple, but loading and sealing operations become inefficient and time-consuming
Solution Approach 1:
The patent applies dynamics by designing the divider wall as a movable component that can pivot between a first position (allowing access for loading refrigerated load) and a second position (sealing the chamber). This single dynamic element enables both loading efficiency and sealing integrity without requiring complex multi-component mechanisms, resolving the contradiction between productivity and structural complexity.
