Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy storage cabins face challenges in controlling temperature due to uncontrollable heat transfer through cabin doors, leading to inaccurate temperature regulation.
Innovation Solution
The energy storage cabin features a cabin door design with an inner and outer door panel separated by a thermal insulation layer and a heat insulation pad, connected via fixation frames and reinforcing ribs, reducing direct contact and enhancing thermal insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the cabin door uses a simple single-panel structure, then the device complexity is reduced, but the thermal insulation performance deteriorates leading to uncontrollable temperature in the energy storage cabin
Solution Approach 1:
The cabin door is divided into multiple independent panels including an inner door panel, outer door panel, and intermediate insulation panels. Each panel serves a specific function: the inner and outer panels provide structural integrity while the intermediate panels contain insulation materials. This segmentation allows the door to achieve better thermal insulation performance without excessive complexity by distributing the insulating function across multiple simplified components.
Solution Approach 2:
The cabin door employs composite construction combining different materials with complementary properties. Metal panels provide strength and durability, while insulation materials (such as foam or fibrous materials) embedded in intermediate panels provide thermal resistance. This composite approach enables the door to simultaneously achieve mechanical strength and effective thermal insulation, resolving the contradiction between simple structure and temperature control accuracy.
2Temperature
If thermal insulation measures are enhanced in the cabin door, then temperature control accuracy is improved, but the device complexity increases
Solution Approach 1:
The insulation system is segmented into multiple independent panels rather than using a single complex thick insulation layer. Each intermediate panel contains insulation material and can be independently manufactured and assembled. This segmentation simplifies the manufacturing process and assembly while achieving cumulative insulation effect, thus improving temperature control without proportionally increasing device complexity.
Solution Approach 2:
The cabin door structure applies different levels of insulation in different regions based on local thermal requirements. Areas with higher heat transfer risk receive enhanced insulation measures, while less critical areas use standard insulation. This localized approach optimizes temperature control accuracy where needed while avoiding unnecessary complexity in other regions, balancing performance and structural simplicity.

AI summary
The present disclosure relates to an energy storage cabin. The energy storage cabin includes a cabin body and a cabin door. The cabin body has an opening and a first accommodation space for accommodating an energy storage element. The cabin door is disposed at the opening of the cabin body in an openable and closable manner. The cabin door includes an inner door panel, an outer door panel, and a connecting member. The inner door panel is located at an inner side of the outer door panel in a stacking manner. A thermal insulation layer is provided between the inner door panel and the outer door panel. The connecting member penetrates the inner door panel to connect the inner door panel with the outer door panel. A heat insulation pad is sandwiched between the inner door panel and the outer door panel at a position where the connecting member penetrates the inner door panel. The cabin door has a relatively low thermal conductivity. Therefore, a quantity of heat/refrigeration in the first accommodation space can be stored for a long time, and a probability that a quantity of heat/refrigeration outside the energy storage cabin is transferred to the first accommodation space through the cabin door is greatly reduced, such that a temperature in the energy storage cabin can be accurately controlled.
